4. 对欧洲食品安全管理局第12条法规规定的矮壮素现存最大残留量的评价

潘淑春

Chlormequat was included in Annex I to Directive 91/414/EEC on 1 December 2009 by Commission Directive 2009/37/EC, amended by Commission Directive 2010/2/EU, and has been deemed to be approved under Regulation (EC) No 1107/2009, in accordance with Commission Implementing Regulation (EU) No 540/2011, as amended by Commission Implementing Regulation (EU) No 541/2011. As the active substance was approved after the entry into force of Regulation (EC) No 396/2005 on 2 September 2008, EFSA is required to provide a reasoned opinion on the review of the existing MRLs for that active substance in compliance with Article 12(1) of the aforementioned regulation. In order to collect the relevant pesticide residues data, EFSA asked the United Kingdom, as the designated rapporteur Member State (RMS), to complete the Pesticide Residues Overview File (PROFile) and to prepare a supporting evaluation report. The PROFile and evaluation report provided by the RMS were made available to the Member States. A request for additional information was addressed to the Member States in the framework of a completeness check period which was initiated by EFSA on 24 June 2015 and finalised on 11 September 2015. After having considered all the information provided, EFSA prepared a completeness check report which was made available to Member States on 13 October 2015. Based on the conclusions derived by EFSA in the framework of Directive 91/414/EEC, the MRLs established by the Codex Alimentarius Commission and the additional information provided by the RMS and Member States, EFSA prepared in December 2015 a draft reasoned opinion, which was circulated to Member States for consultation via a written procedure. Comments received by 3 February 2016 were considered during the finalisation of this reasoned opinion. The following conclusions are derived. The metabolism of chlormequat chloride has been investigated in cereals as well as in rotational crops. A similar metabolism was depicted in these studies with chlormequat being the only relevant compound identified. Hydrolysis studies simulating beer brewing (100°C, pH 4 for 120 minutes) and bread making (100°C, pH 5 for 40 minutes) showed that processing conditions relevant for cereals are not expected to degrade the parent compound significantly but a general residue definition for processed commodities could not be derived in the absence of standard hydrolysis studies. Therefore, a residue definition for cereal crops for monitoring and risk assessment was proposed as the sum of chlormequat and its salts, expressed as chlormequat chloride. The residue definition derived for cereals was also deemed appropriate for pears and cultivated fungi where carry-over of unchanged parent compounds may occurs. A validated analytical method for this residue definition in high water content, dry commodities and cereal straw is available. The available residue trials data were considered sufficient to derive MRL proposals as well as risk assessment values for all primary crops under evaluation, except for grass which residue trials were not available. Based on the metabolism studies, no significant residues levels of chlormequat are expected in the investigated rotational crops (cereals, roots, pulses and oilseeds and leafy crops), the main part of the radioactivity being incorporated in the plant matrix. However, EFSA derived MRLs proposals in order to cover unintentional carry-over of residues in pears (due to former uses) and cultivated fungi (grown on substrate composed of cereals straw treated with chlormequat). Different options for MRLs were derived on the basis on monitoring data and different methodologies. A risk management decision should still be taken on the level of these MRLs and the period of their applicability. In addition, studies investigating the magnitude of residues in processed commodities of wheat, barley and oats allowed EFSA to derive robust processing factors for wheat (bran, flour and bread), barley (pot/pearl, malt and beer) and oat flakes. Chlormequat is authorised for use in cereals which might be fed to livestock. The metabolism of chlormequat was investigated in lactating goats and laying hens. As metabolic pathways are expected to be similar in ruminants and pigs, the results of the goat metabolism study could be extrapolated to swine. From these studies, EFSA proposed a general residue definition for monitoring and risk assessment in livestock commodities as the sum of chlormequat and its salts, expressed as chlormequat chloride. A validated analytical method for enforcement of the proposed residue definition in commodities of animal origin is available. Based on the available feeding studies for ruminants and poultry, MRLs and risk assessment values were derived in ruminants, swine and poultry products. Chronic and acute consumer exposure resulting from the authorised uses reported in the framework of this review and the possible carry-over in non-treated pears and cultivated fungi (considering the most protective assumption) was calculated using revision 2 of the EFSA PRIMo. The highest chronic exposure represented 28.9% of the ADI (Danish children) and the highest acute exposure amounted to 33.1% of the ARfD (wheat). Apart from the MRLs evaluated in the framework of this review, internationally recommended CXLs have also been established for chlormequat. Additional calculations of the consumer exposure, considering these CXLs, were therefore carried out and the highest chronic exposure represented 29.3% of the ADI (Danish children) and the highest acute exposure amounted to 62.3% of the ARfD (milk and milk products).

5. 烘焙咖啡通过增加人神经母细胞瘤SH-SY5Y细胞中蛋白酶体β-分泌酶的降解来减少β-淀粉样蛋白的产生

mj

流行病学研究表明，咖啡消费可能与发生几种神经系统疾病，包括阿尔茨海默病（AD）的风险较低有关。咖啡因是咖啡预防效果的重要候选成分。但是，咖啡中其他成分的贡献尚不清楚。为了阐明这个问题，研究了烘焙咖啡豆对人神经母细胞瘤SH-SY5Y细胞中β-分泌酶（BACE1）表达的影响。 咖啡（2％）在24小时后的培养基中Aβ积聚减少至对照水平的80％。因此，BACE1表达在12小时降低至对照水平的70％。使用环己酰亚胺和蛋白酶体抑制剂MG132的实验表明，咖啡通过激活蛋白酶体活性来增强BACE1降解。此外，咖啡激活cAMP依赖性蛋白激酶，并因此激活蛋白酶体26S亚基，以及非ATP酶11（PSMD11）的丝氨酸残基的磷酸化。邻苯二酚，一种被称为儿茶酚或1,2-二羟基苯的强抗氧化剂，在焙烧过程中由绿原酸产生，也通过激活蛋白酶体活性降低BACE1的表达。此外，邻苯二酚降低SH-SY5Y细胞中的Aβ产生。 数据表明，烘焙过程可能对AD中咖啡消费的保护作用至关重要。

线粒体的功能就像一种广谱的特点例如静息线粒体活性 、最大或最小的氧化磷酸化的能力（OXPHOS）、线粒体动力学、翻滚和可塑性。线粒体和胰岛素敏感性之间的相互作用是双向的，并且取决于组织、实验模型、方法论，和线粒体功能测试特点的变化。人类骨骼肌的线粒体发生异常，一方面可能是遗传因素造成的，例如线粒体含量较正常量低，另一方面是后天的，如OXPHOS能力或者可塑性的受损。线粒体异常最终会导致线粒体功能的降低或者导致胰岛素抵抗型的2型糖尿病。类似的机制也可能发生在脂肪组织和心脏肌肉。与此相反，线粒体的氧化能力瞬时上调会导致肥胖的胰岛素抵抗的人有脂肪肝或没有脂肪肝，引起氧化应激和脂肪肝疾病的下降。这些数据表明在人类代谢性疾病过程中，胰岛素敏感性和氧化代谢之间具有高度组织特异性的相互作用。

9. 欧洲联盟对来自人类、动物和食物的人畜共患病和指标细菌的抗菌素耐药性的总结报告 2014

潘淑春

The data on antimicrobial resistance in zoonotic and indicator bacteria in 2014, submitted by 28 EU Member States (MSs), were jointly analysed by EFSA and ECDC. Resistance in zoonotic Salmonella and Campylobacter species from humans, animals and food, and resistance in indicator Escherichia coli as well as meticillin-resistant Staphylococcus aureus in animals and food was assessed. ‘Microbiological’ resistance was assessed using epidemiological cut-off (ECOFF) values; for some countries, quantitative data on human isolates were interpreted in a way which corresponds closely to the ECOFF-defined ‘microbiological’ resistance. In Salmonella from humans, high proportions of isolates were resistant to ampicillin, sulfonamides and tetracyclines, whereas resistance to third-generation cephalosporins and to fluoroquinolones remained generally low, although it was markedly higher in some serovars commonly associated with broilers and turkeys. In Salmonella and Escherichia coli isolates from broilers, fattening turkeys and meat thereof, resistance to ampicillin, (fluoro)quinolones, tetracyclines and sulfonamides was frequently detected, whereas resistance to third-generation cephalosporins was uncommon. For the first time, presumptive extended spectrum beta-lactamase (ESBL)-/AmpC-/carbapenemase production in Salmonella and Escherichia coli was monitored in poultry. The occurrence of ESBL-/AmpC-producers was low, and carbapenemase-producers were not detected. Resistance to colistin was observed at low levels in Salmonella and Escherichia coli from poultry and meat thereof. In Campylobacter from humans, a high to very high proportion of isolates were resistant to ciprofloxacin and tetracyclines, whereas resistance to erythromycin was low to moderate. Resistance to fluoroquinolones in some MSs was extremely high; in such settings, the effective treatment options for human enteric Campylobacter infection may be significantly reduced. High resistance to ciprofloxacin and tetracyclines was observed in Campylobacter isolates from broilers and broiler meat, whereas much lower levels were recorded for erythromycin. Co-resistance to critically important antimicrobials in both human and animal isolates was generally uncommon, but very high to extremely high MDR levels were observed in some Salmonella serovars. A minority of Salmonella isolates from animals belonging to a few serovars (notably Kentucky and Infantis) exhibited high-level resistance to ciprofloxacin.  © European Food Safety Authority, 2016 Summary:  Zoonoses are infections that are transmissible between animals and humans. Infections can be acquired directly from animals, via environmental exposure or through the ingestion of contaminated foodstuffs. The severity of these diseases in humans can vary from mild symptoms to life-threatening conditions. Zoonotic bacteria that are resistant to antimicrobials are of particular concern, as they might compromise the effective treatment of infections in humans. Data from the EU Member States (MSs) are collected and analysed in order to monitor the occurrence of antimicrobial resistance (AMR) in zoonotic bacteria isolated from humans, animals and food in the European Union (EU). For 2014, 28 MSs reported data on AMR in zoonotic bacteria to the European Food Safety Authority (EFSA), and 21 MSs submitted data to the European Centre for Disease Prevention and Control (ECDC). In addition, three other European countries provided information. The enhanced monitoring of AMR in bacteria from food and food-producing animals set out in the Commission Implementing Decision 2013/652/EU was successfully implemented in reporting MSs and non-MSs in the EU during 2014. In accordance with the legislation, the 2014 AMR data on food and food-producing animals specifically targeted different poultry populations and meat derived thereof. EFSA and ECDC performed the analyses of the data, the results of which are published in this EU Summary Report on AMR. Data on resistance were reported regarding Salmonella and Campylobacter isolates from humans, poultry and meat thereof, whereas data on indicator Escherichia coli isolates were related only to poultry and meat derived thereof. Some MSs also reported data on the occurrence of meticillin-resistant Staphylococcus aureus (MRSA) in animals and food; the antimicrobial susceptibility of MRSA isolates was additionally reported by two countries. The quantitative data on AMR in isolates from humans, poultry and meat thereof were assessed using harmonised epidemiological cut-off values that define ‘microbiological’ resistance, i.e. reduced susceptibility to the antimicrobials tested, as well as using clinical breakpoints (CBPs), where considered appropriate. The categorical (qualitative) data on AMR in isolates from humans interpreted by using CBPs were aligned with ‘microbiological’ resistance by combining ‘clinically resistant’ and ‘intermediate resistant’ isolates into a non-susceptible group. Isolates from different sources should only be directly compared when methods and interpretive criteria are comparable. For the first time, all MSs reported AMR data on poultry and meat thereof at the isolate level. This enabled analysis of multi-drug resistance (MDR) and co-resistance patterns to critically important antimicrobials in both human and animal isolates at the EU level but also at country level. In addition, for all bacterial species, AMR data could be analysed at the production-type level, such as broilers and laying hens of Gallus gallus and fattening turkeys, which allows the analysis of the data to be fine-tuned. More specifically, reporting data at isolate level allowed characterisation of important patterns of resistance, enabling Salmonella serovars to be linked to particular resistance patterns and to identify high-level resistance to fluoroquinolones and important resistance phenotypes in both Salmonella and indicator E. coli. The information published in this report provides an overview of resistance in most MSs with detailed consideration of certain important aspects. Highlights of this report include the continued monitoring of the spread of certain highly resistant Salmonella serovars. Two serovars in particular, S. Infantis and S. Kentucky, contribute significantly to the overall numbers of multidrug-resistant Salmonella in Europe. Both serovars display high-level resistance to ciprofloxacin, which is an important public health concern because ciprofloxacin is a common first-line treatment for invasive salmonellosis in humans. The introduction of Commission implementing Decision 2013/652/EU with revised panels of antimicrobials to be tested has been timely, preceding recent reports of emergence of transferable colistin and erythromycin resistance in Asia (Liu et al., 2015; Wang et al., 2015). The continually evolving threat from emerging resistance underlines the need to review the data collected, interpret the findings and assess trends. This report has attempted to highlight some of the most important findings in 2014, but space constraints mean that it is necessarily selective.  The inclusion within the harmonised monitoring scheme of a supplementary panel of antimicrobials, to be tested when certain resistances to an initial panel of antimicrobials are detected, enabled detailed screening of resistance to three carbapenem compounds. No resistance to meropenem was detected and this is a crucial finding, because carbapenems are critically important in human medicine. Only nine E. coli isolates from broilers and one from fattening turkeys isolated in 6 MSs showed resistance to ertapenem, and all these isolates presented a putative extended spectrum beta-lactamase (ESBL) or AmpC phenotype. These isolates are being further investigated. The supplementary testing also allowed, for the first time, detailed characterisation of the beta-lactam resistance phenotypes occurring in Salmonella and indicator E. coli. It enabled further phenotypic characterisation of third-generation cephalosporin and carbapenem resistance in Salmonella and indicator E. coli, by inferring presumptive profiles of ESBL-/AmpC-/carbapenemase-producers. The occurrence of ESBL-/AmpC-producers in Salmonella and indicator E. coli from poultry was assessed as being at low levels. It also showed that S. Infantis in Italy and S. Heidelberg in the Netherlands have probably each acquired a different mechanism of third-generation cephalosporin resistance (an ESBL enzyme in S. Infantis and an AmpC enzyme in S. Heidelberg) and have subsequently spread within each MS.

潘淑春

Objectives: Silver nanoparticles (AgNPs) as antibacterial agents are incorporated in many consumer products, while the use as antiviral agents is an ongoing area of research. We evaluated the antiviral properties of AgNPs of variable sizes (10, 75, and 110 nm) and doses (25, 50, and 100 μg/mL) at different contact time points against feline calicivirus (FCV), a surrogate for norovirus. Materials and Methods: Antiviral effects of the AgNPs were determined by comparing the infectivity of FCV, the appearance of cytopathic effects (CPEs), and the integrity of the viral capsid protein in viral suspension treated with AgNPs with the untreated controls. Results: The 10 nm AgNPs at 50 and 100 μg/mL concentrations inactivated the FCV beyond the limit of detection, resulting in a decrease of up to 6.5 log10 viral titer, prevented development of CPEs, and reduction in the western blot band signal of the viral capsid protein. No significant antiviral effect was observed for the 75 and 110 nm AgNPs. Conclusions and Applications: These results demonstrate that the antiviral effects of AgNPs are both size and dose dependent, thus potential applications of AgNPs as antiviral agents to prevent contamination of foodborne viruses need to consider size and dose effects.

Background High cholesterol levels are of concern because they have been linked with heart disease, stroke, bile imbalance, leading to gallstones, and blood flow interferences. The purpose of this research was to determine the effect that waffle batter content (egg versus banana puree) has on physical and sensory characteristics and acceptability of waffles. Methods After IRB approval, twenty college-aged students, 19 and older, were recruited to test two different samples. The control waffle recipe and the second was the same waffle recipe with banana puree substituted for eggs. Samples were tested subjectively using a Hedonic scale (1-9) and triangle test. Objective testing included the cook time, line spread test, volumeter, vernier calipers, Nutritionist Pro analysis and the TA.XT Plus texture analyzer. Statistical tests included mean, median, mode and t - tests with an alpha value of 0.05. Results Subjective testing revealed little difference in the acceptability of the two waffles. Nutritional analysis using the Nutritionist Pro system showed that that the waffle made with banana was lower in cholesterol and lower in fat. Objective testing revealed that the banana waffle had batter that was less viscous, larger in volume, firmer, and did not rise as high as the control. Conclusions This research shows that the egg content of waffles can be successfully be replaced with banana puree. The effects of such alterations has little to no effect on overall palatability or likeability of the waffle, but it would lower the cholesterol content of the waffle and be more affordable.

25. 粮农组织-新闻文章 ︰ 中国和粮农组织加强南南合作

潘淑春

The Food and Agriculture Organization of the United Nations (FAO) and the Government of the People's Republic of China have announced plans to intensify their partnership in south-south cooperation activities, FAO announced today. After decades of successful collaboration, China and FAO have agreed to broaden the scope of their cooperation, building on their achievements to further promote rural development worldwide. A new Memorandum of Understanding on the Strategic Cooperation on Agriculture and Food Security, agreed Saturday, will pave the way for this. The MoU will facilitate Chinese assistance to other countries through China's Belt and Road Initiative and further afield with other countries in Africa and Latin America. "This comprehensive partnership between China and FAO opens the door for closer collaboration to work together on transboundary diseases, agricultural value chain development, innovative science and technology to combat climate change, and further development of Information and Communication Technology (ICT)," said FAO Director-General, José Graziano da Silva. The Director-General made the remarks today following a meeting with China's Minister of Agriculture, Han Changfu. Minister Han noted that the G20 Countries had just last week highlighted the importance of promoting ICT in agricultural applications and he looked forward to the Director-General's leadership in this area. The new agreement between FAO and China aims to build on more than 40 years of collaboration between the two, which in recent years has delivered successful initiatives in South-South Cooperation for food security and nutrition. China has been one of the largest contributors to the SSC, both in financial terms and through sharing its own extensive experience, knowledge and technologies with other countries. For its part, FAO has provided technical support to more than 400 agricultural projects benefiting tens of millions of people across China. China has much to offer the world Signed in Xi'an, the historic starting point of the Silk Road that allowed silk, horses, gold and ideas to flow between East Asia and Europe, the new MoU will promote the complementarities between FAO's Strategic Programmes and Regional Initiatives and China's "Belt and Road Initiative", a vast infrastructure investment programme linking Asia and Europe and extending to Oceania and East Africa. "China has much to offer to all developing countries in the world in terms of agriculture and food security," Graziano said, pointing to the example of an ancient farming system where farmers in Zhejiang Province combine rice farming with aquaculture, literally growing fish in their flooded paddy fields. The rice paddies offer protection and organic food for the fish. In return the fish soften the soil, provide nutrients and oxygen for the rice and consume insects and weeds that are harmful to the rice. The rice-fish system has been in existence for one-thousand years and was designated a Globally Important Agricultural Heritage System (GIAHS) by FAO. "China's experience with GIAHS is remarkable and could be a source of inspiration to many countries," Graziano concluded. Since 1990, China has successfully lifted 138 million people out of chronic hunger and reached the World Food Summit Goal, in addition to reaching the Millennium Development Goal of halving the prevalence of hunger ahead of the 2015 deadline. There is a mutual understanding that the MoU will be beneficial not only for both parties, but also for many developing countries in the context of the 2030 Agenda for Sustainable Development and to reach the goal of zero hunger worldwide within this generation.

28. 405纳米可见光对鸡皮肤的空肠弯曲菌的生存和不锈钢的影响

潘淑春

Campylobacter spp. are foodborne pathogens responsible for a significant portion of human cases of bacterial-mediated gastrointestinal disease. A primary method for the introduction of Campylobacter into the food supply is through poultry products. Reducing the number of Campylobacter on poultry products may reduce the incidence of human disease. Research has been conducted on the use of light to inactivate Campylobacter on poultry products and processing environments. More recently, the use of high intensity visible 405-nm light has been proposed for the elimination of pathogenic bacteria. This study investigated the ability of 405-nm light to reduce Campylobacter jejuni and Campylobacter coli in poultry products. Campylobacter in chicken exudate were placed onto chicken skin or food-grade stainless steel before treatment with 405-nm light. A range of 405-nm light doses were applied to cocktails of six C. jejuni or six C. coli strains in exudate at 10°C to minimize thermal effects. Little difference was observed between inactivation of C. jejuni and C. coli on poultry skin with only minor average reductions of 1.7 logs and 2.1 logs, respectively, at the maximal dose of 184–186 J/cm2. More noticeable differences were observed when the samples were placed on stainless steel and treated with a dose of 89 J/cm2, producing an average reduction of 3.0 logs for C. coli but only 1.1 logs for C. jejuni. The maximal dose (181–183 J/cm2) applied to Campylobacter on stainless steel produced significant (p ≤ 0.05) reductions for C. jejuni and C. coli of 4.9 logs and 5.1 logs, respectively. However, significant 405-nm-mediated reductions in Campylobacter numbers required exposure times to achieve necessary dose levels that might be impractical under processing conditions. In addition, the most potent exposure times likely produced secondary thermal effects by raising sample surface temperatures above 48°C.

潘淑春

The U.S. Agency for International Development (USAID) West Bank and Gaza Mission (WBG) is providing a $13 million U.S. contribution to the United Nations World Food Programme (WFP) for food assistance in the West Bank and Gaza. This contribution will enable WFP to provide 95,000 food-insecure people in Gaza with more than 6,700 metric tons of food assistance.  In addition, this money will be used for food distributions to 41,500 people in the West Bank and to support the electronic food voucher program benefiting 50,000 people there.  These activities not only allow an immediate response to the humanitarian needs in Gaza, but also provide continued support to Palestinians in the West Bank and Gaza who struggle to buy or produce enough food to live a normal, healthy life.  In addition, the electronic voucher project in the West Bank is an innovative way to provide food assistance while supporting resilient societies as well as the development of small businesses and the local economy through locally sourced foods. Prior to this $13 million commitment, U.S. contributions to WFP since July 2014 have totaled more than $19 million, providing more than 15,000 metric tons of food to some half a million vulnerable Palestinians in the West Bank and Gaza.  These results are due to the excellent partnership between the USAID and WFP who have worked together in the West Bank and Gaza for more than a decade.  The U.S.-funded food assistance activities are implemented in the West Bank in Gaza by WFP in partnership with the U.S. NGO, Global Communities.   The U.S. Government, through USAID, is the leading provider of bilateral development assistance to the Palestinians, having provided more than $4.6 billion since 1994 for programs in the areas of education; health and humanitarian assistance; private enterprise; democracy and governance; and water resources and infrastructure.

潘淑春

A self-powered time-temperature integrator (TTI) was developed by modifying a biofuel cell and characterised in terms of kinetics and temperature dependency. The TTI was composed of two immobilised enzyme electrodes, (+) and (−), and a cavity containing substrates. The enzymes (laccase and glucose oxidase), mediators (methylene blue, 8-hydroxyquinoline-5-sulfonic acid hydrate, ferrocenium hexafluorophosphate, 4,4-sulfonydiphnol) and stabilisers (pyrrole) were immobilised on a glassy carbon electrode by electrodeposition by applying a square wave (10 s at 4 V then 3 s at 0.5 V) for 180 cycles. The primarily measured output voltage, which corresponds to a rate of food quality change, was mathematically converted to a secondary variable, its integral value, representing the food quality level. The temperature dependency of the self-powered TTI was modified by using sodium azide, and the shelf-life of TTI could be adjusted to match that of the food product by changing glucose concentrations. The optimum Arrhenius activation energy was found to be 78.22 kJ/mol with a sodium azide concentration of 0.02 M and the glucose concentration at the maximum (5.05 M), it used continuously for 7 days at 25 °C. Through a case study with milk, the novel TTI was found to accurately detect milk quality changes. The self-powered TTI can be utilised as an intelligent versatile sensor in the food distribution system with an appropriate IT platform. In particular, if the TTI is incorporated with RFID tag, we will see a new generation of smart RFID tag for intelligent food packaging.

39. 粮农组织： 粮农组织食品价格指数 2016年开始降至近 7 年来新低

潘淑春

The Food Price Index averaged 150.4 points in January, down 16 percent from a year earlier and registering its lowest level since April 2009. The FAO Food Price Index is a trade-weighted index tracking international market prices for five key commodity groups: major cereals, vegetable oils, dairy, meat and sugar. The main factors underlying the lingering decline in basic food commodity prices are the generally ample agricultural supply conditions, a slowing global economy, and the strengthening of the US dollar. This month, FAO also raised its forecast for worldwide cereal stocks in 2016, as a result of lowering its projected consumption and raising 2015 production prospects. The FAO Sugar Price Index fell 4.1 percent from December, its first drop in four months, as crop conditions improved in Brazil, by far the world's leading sugar producer and exporter. The Dairy Price Index dropped by 3.0 percent on the back of large supplies, in both the EU and New Zealand, and torpid world import demand. The FAO Cereal Price Index declined 1.7 percent (to 149.1 points) amid ample global supplies and increased competition for export markets, especially for wheat and maize, as well as a strong US dollar. The Vegetable Oil Price Index dropped 1.7 percent, mainly because of a decline in soy oil prices reflecting expectations of ample global soybean supplies. The Meat Price Index moved 1.1 percent lower than its revised December value, with prices of all meat categories falling, except pigmeat, which was sustained by the opening of private storage aid in the EU. Mixed early prospects for 2016 harvests Weather patterns associated with El Niño are sending mixed signals about the early prospects for cereal crops in 2016, especially in the Southern Hemisphere, according to FAO's Cereal Supply and Demand Brief, also released today. 2016 crop prospects have been "severely weakened" in Southern Africa, and a 25 percent cut in wheat production in South Africa now appears likely. Conditions for the crop are generally favourable in the Russian Federation and the European Union, but winter plantings declined in the United States and Ukraine. The area under wheat is also expected to be cut in India, following a poor monsoon and below average rains since October. The 2016 outlook for rice along and south of the Equator is "dim" due, at times, to insufficient water and, at others, to excessive rains. As for the 2015 season, FAO modestly raised its forecast for world cereal production to 2 531 million tonnes, up slightly from that released in December. Wheat output in Canada and Russia and maize output in China, Canada and Paraguay drove the upward revision. FAO also slightly raised its expectation regarding 2015 world rice production, mostly on account of higher forecasts for China, Viet Nam and the United States. At the same time, FAO lowered its forecast for world cereal utilization in the 2015/16 season to 2 527 million tonnes, which remains 0.8 percent above that of the previous year.This reflects a 2.0 percent increase for wheat, largely on account of higher livestock feed use in developed countries and a 0.3 percent increase in maize. World rice utilization is projected to expand by 1.1 percent, keeping world per-capita consumption stable. As a result of the upgraded production and downgraded consumption forecasts, world cereal stocks are set to end the 2016 seasons at 642 million tonnes, higher than they began. That level implies a steady and comfortable global cereal stock-to-use ratio of around 25 percent. However, the inventory build-up varies geographically and depending on the crop. Notable increases in wheat inventories are forecast for the United States, European Union and China whereas some reductions are likely in Canada, India and the Islamic Republic of Iran. On the other hand, world rice stocks would need to be drawn down to bridge the expected gap between world production and consumption, with much of the release likely to concern India and Thailand, the two leading rice exporters.

43. 美国大豆协会极力推动欧洲大豆性状的及时审批

panshuchun

ASA ramped up its call for approval of three outstanding soybean traits by the European Union this week, saying that the tools are a critical part of the industry’s ongoing quest to meet sustainability and consumer demand goals, and that continued delays pose serious issues both for farmers and industry. In a letter to European Commissioner Vytenis Andriukaitis Tuesday, ASA expressed deep concern with the EU’s delayed authorization of three new soybean traits: Monsanto’s dicamba-tolerant RR2Xtend and Vistive Gold high oleic traits, as well as Bayer CropScience’s isoxaflutole-resistant Balance Bean trait. All three traits received positive opinions from the European Food Safety Authority in May and June of last year, and have awaited approval for five months following an Appeals Committee ruling in January. “The Commission’s lack of action in providing final authorization for these soy events has already caused unnecessary uncertainty, disruption and cost in the agricultural supply chain. Immediate authorization by the European Commission is needed to avoid substantial additional unnecessary costs and possible disruption to the essential supply of feedstocks needed by the EU’s livestock, poultry and feed industries, which are more than 70 percent dependent on imports of vegetable protein,” the letter stated. ASA also cited repeated assurances over the course of several months from EU officials that approval of the three traits was imminent as providing a false sense of security for farmers looking to utilize the traits to meet sustainability goals and comply with the food industry’s ongoing move away from trans fats in the American marketplace. “As the threat of resistant weeds continues to move across soybean country, and the specter of increased input costs coupled with a down farm economy looms over so many soybean farmers, we need more options in the marketplace. We are not benefited by new products that are stuck in a malfunctioning approvals pipeline,” said ASA President Richard Wilkins, a farmer from Greenwood, Del. “Add to that the ability of high-oleic soy to help answer the growing market for cooking oils free of trans fats, and you see the real value in these three traits. “The European Commission must abide by the timelines set out in in its own regulations, as well as its obligations under the World Trade Organization, and give these traits the approvals that it has said are forthcoming,” Wilkins added.

51. 世界卫生日的精神食粮

潘淑春

Getting your daily nutrients can be more difficult now than it was in the past. Fruit and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us get today. A study of British nutrient data from 1930 to 1980, published by the British Food Journal, found that in 20 vegetables the average calcium content had declined by 19 percent, iron by 22 percent and potassium by 14 percent.  Another study concluded that we would have to eat eight oranges today to derive the same amount of Vitamin A that our grandparents would have gotten from one. The reasons for this include:  Industrial farming, processing and trading methods are causing a decline of minerals e.g. copper, iron, magnesium and potassium, in fruit and vegetables.. Modern-day intensive agricultural methods are stripping more and more nutrients from the soil in which we grow food.. Artificial fertilizers used to speed the growth and productivity of crops might not take account of the delicate balance of mineral requirements in plants and foods.. Fruit and vegetable often embark on a long journey before landing in our homes. Nutritionists say this may be affecting their vitamin content as fresh fruit and vegetables are more likely to contain the most vitamins.. Using artificial ripening on vegetables like tomatoes lowers the nutritional value of the products - tomatoes accumulate nearly all the sugars and many flavonoids in their last 3 days on the vine.. To ensure you get the most nutritious fruits and vegetables, you should buy regularly from local organic farms.

潘淑春

Metabolite profiling has been used to assess the potential for unintended composition changes in potato (Solanum tuberosum L. cv. Desirée) tubers, which have been genetically modified (GM) to reduce glycoalkaloid content, via the independent down-regulation of three genes SGT1, SGT2 and SGT3 known to be involved in glycoalkaloid biosynthesis. Differences between the three groups of antisense lines and control lines were assessed using liquid chromatography–mass spectrometry (LC–MS) and gas chromatography (GC)–MS, and data analysed using principal component analysis and analysis of variance. Compared with the wild-type (WT) control, LC–MS revealed not only the expected changes in specific glycoalkaloid levels in the GM lines, but also significant changes in several other metabolites, some of which were explicable in terms of known pathways. Analysis of polar and non-polar metabolites by GC–MS revealed other significant (unintended) differences between SGT lines and the WT, but also between the WT control and other control lines used.

60. “食物成瘾”的神经生物学及其对肥胖治疗的影响与政策

panshuchun

There is a growing view that certain foods, particularly those high in refined sugars and fats, are addictive and that some forms of obesity can usefully be treated as a food addiction. This perspective is supported by a growing body of neuroscience research demonstrating that the chronic consumption of energy-dense foods causes changes in the brain's reward pathway that are central to the development and maintenance of drug addiction. Obese and overweight individuals also display patterns of eating behavior that resemble the ways in which addicted individuals consume drugs. We critically review the evidence that some forms of obesity or overeating could be considered a food addiction and argue that the use of food addiction as a diagnostic category is premature. We also examine some of the potential positive and negative clinical, social, and public policy implications of describing obesity as a food addiction that require further investigation. .

Using pattern analysis, we investigated the relationship between plasma fatty acid patterns, dietary intake, and biomarkers of metabolic health using data from the Irish National Adult Nutrition Survey. Methods and results Plasma fatty acid patterns were derived from 26 plasma fatty acids using k-means cluster analysis. Four clusters were identified, each with a distinct fatty acid profile. Cluster 1 included high proportions of linoleic acid (LA) and low proportions of stearic acid (SA); cluster 2 was higher in n-3 polyunsaturated fatty acids and SA; the profile of cluster 3 was higher in very-long-chain saturated fatty acid (VLCSFA) and lower in α-linolenic acid (ALA) (cluster 3); while cluster 4 was higher in fatty acids related to de novo lipogenesis and 20:3n-6 and lower in LA (cluster 4). In general, cluster 4 was associated with adverse metabolic profile and higher metabolic risk (p < 0.033). Clusters 2 and 3 were associated with healthier and protective phenotypes (p < 0.033). Conclusion Distinct fatty acid patterns were identified which were related to demographics, dietary habits, and metabolic profile. A pattern higher in VLCSFA and lower in ALA was associated with healthier metabolic outcome.

This article summarizes current data and approaches to assess sodium intake in individuals and populations. A review of the literature on sodium excretion and intake estimation supports the continued use of 24-h urine collections for assessing population and individual sodium intake. Since 2000, 29 studies used urine biomarkers to estimate population sodium intake, primarily among adults. More than half used 24-h urine; the rest used a spot/casual, overnight, or 12-h specimen. Associations between individual sodium intake and health outcomes were investigated in 13 prospective cohort studies published since 2000. Only three included an indicator of long-term individual sodium intake, i.e., multiple 24-h urine specimens collected several days apart. Although not insurmountable, logistic challenges of 24-h urine collection remain a barrier for research on the relationship of sodium intake and chronic disease. Newer approaches, including modeling based on shorter collections, offer promise for estimating population sodium intake in some groups.

潘淑春

Background. During 2012, Massachusetts adopted comprehensive school competitive food and beverage standards that closely align with Institute of Medicine recommendations and Smart Snacks in School national standards. Objective. We examined the extent to which a sample of Massachusetts middle schools and high schools sold foods and beverages that were compliant with the state competitive food and beverage standards after the first year of implementation, and complied with four additional aspects of the regulations. Design. Observational cohort study with data collected before implementation (Spring 2012) and 1 year after implementation (Spring 2013). Participants/setting. School districts (N=37) with at least one middle school and one high school participated. Main outcome measures. Percent of competitive foods and beverages that were compliant with Massachusetts standards and compliance with four additional aspects of the regulations. Data were collected via school site visits and a foodservice director questionnaire. Statistical analyses performed. Multilevel models were used to examine change in food and beverage compliance over time. Results. More products were available in high schools than middle schools at both time points. The number of competitive beverages and several categories of competitive food products sold in the sample of Massachusetts schools decreased following the implementation of the standards. Multilevel models demonstrated a 47-percentage-point increase in food and 46-percentage-point increase in beverage compliance in Massachusetts schools from 2012 to 2013. Overall, total compliance was higher for beverages than foods. Conclusions. This study of a group of Massachusetts schools demonstrated the feasibility of schools making substantial changes in response to requirements for healthier competitive foods, even in the first year of implementation.

76. 对超重和肥胖的绝经后妇女随机对照试验证明，绿茶提取物和COMT基因型可改变空腹血清胰岛素和血浆脂联素浓度

潘淑春

Abstract. Background: Green tea consumption has been associated with favorable changes in body weight and obesity-related hormones, although it is not known whether these changes result from green tea polyphenols or caffeine. Objective: We examined the impact of decaffeinated green tea extract (GTE) containing 843 mg of (−)-epigallocatechin-3-gallate on anthropometric variables, obesity-associated hormones, and glucose homeostasis. Methods: The Minnesota Green Tea Trial was a 12-mo randomized, double-blind, placebo-controlled clinical trial of 937 healthy postmenopausal women assigned to either decaffeinated GTE (1315 mg total catechins/d) or a placebo, stratified by catechol-O-methyltransferase (COMT) genotype. This study was conducted in a subset of 237 overweight and obese participants [body mass index (BMI) ≥25 kg/m2]. Results: No changes in energy intake, body weight, BMI, or waist circumference (WC) were observed over 12 mo in women taking GTE (n = 117) or placebo (n = 120). No differences were seen in circulating leptin, ghrelin, adiponectin, or glucose concentrations at month 12. Participants randomly assigned to GTE with baseline insulin ≥10 μIU/mL (n = 23) had a decrease in fasting serum insulin from baseline to month 12 (−1.43 ± 0.59 μIU/mL), whereas those randomly assigned to placebo with baseline insulin ≥10 μIU/mL (n = 19) had an increase in insulin over 12 mo (0.55 ± 0.64 μIU/mL, P < 0.01). Participants with the homozygous high-activity (G/G) form of COMT had significantly lower adiponectin (5.97 ± 0.50 compared with 7.58 ± 0.53 μg/mL, P = 0.03) and greater insulin concentrations (7.63 ± 0.53 compared with 6.18 ± 0.36 μIU/mL, P = 0.02) at month 12 compared with those with the low-activity (A/A) genotype, regardless of treatment group. Conclusions: Decaffeinated GTE was not associated with reductions in body weight, BMI, or WC and did not alter energy intake or mean hormone concentrations in healthy postmenopausal women over 12 mo. GTE decreased fasting insulin concentrations in those with elevated baseline fasting concentrations. The high-activity form of the COMT enzyme may be associated with elevations in insulin and a reduction in adiponectin concentrations over time. This trial was registered at http://www.clinicaltrials.gov as NCT00917735. .

77. 对硝磺草酮活性物质的农药风险评估的同行评价 -欧洲食品安全局

潘淑春

Commission Implementing Regulation (EU) No 844/2012 (hereinafter referred to as ‘the Regulation’) lays down the procedure for the renewal of the approval of active substances submitted under Article 14 of Regulation (EC) No 1107/2009. The list of those substances is established in Commission Implementing Regulation (EU) No 686/2012. Mesotrione is one of the active substances listed in Regulation (EU) No 686/2012. In accordance with Article 1 of the Regulation, the rapporteur Member State (RMS), the United Kingdom, and co-rapporteur Member State (co-RMS), Belgium, received an application from Syngenta Crop Protection AG for the renewal of approval of the active substance mesotrione. Complying with Article 8 of the Regulation, the RMS checked the completeness of the dossier and informed the applicant, the co-RMS (Belgium), the European Commission and the European Food Safety Authority (EFSA) about the admissibility. The RMS provided its initial evaluation of the dossier on mesotrione in the renewal assessment report (RAR), which was received by EFSA on 23 February 2015. In accordance with Article 12 of the Regulation, EFSA distributed the RAR to the Member States and the applicant, Syngenta Crop Protection AG, for comments on 17 April 2015. EFSA also provided comments. In addition, EFSA conducted a public consultation on the RAR. EFSA collated and forwarded all comments received to the European Commission on 18 June 2015. Following consideration of the comments received on the RAR, it was concluded that additional information should be requested from the applicant, and that EFSA should conduct an expert consultation in the areas of mammalian toxicology, residues, environmental fate and behaviour and ecotoxicology. In accordance with Article 13(1) of the Regulation, EFSA should adopt a conclusion on whether mesotrione can be expected to meet the approval criteria provided for in Article 4 of Regulation (EC) No 1107/2009 of the European Parliament and of the Council. The conclusions laid down in this report were reached on the basis of the evaluation of the representative use of mesotrione as a herbicide on maize, as proposed by the applicant. Full details of the representative uses can be found in Appendix A of this report. The use of mesotrione according to the representative use proposed at EU level results in a sufficient herbicidal efficacy against the target weeds. In the area of identity, physical/chemical/technical properties and methods of analysis, a data gap was identified for specifying two of the significant impurities on dry weight basis. Data gaps were identified for validation data of methods used in data generation. Regarding the mammalian toxicology area, a number of data gaps were identified. The toxicological relevance of individual impurities present in the technical specification in comparison with the toxicity profile of mesotrione needs to be addressed. Interspecies comparative in vitro metabolism should be conducted to identify at least potentially unique human metabolites to mesotrione. As the genotoxic potential of metabolite AMBA could not be ruled out due to positive results obtained in an in vitro cytogenetic assay, and no in vivo genotoxicity testing was performed, a critical area of concern has been identified regarding consumer risk assessment; repeated dose toxicity would also have to be addressed for this metabolite. Mesotrione is proposed to be classified as Repr. 2 for development by the peer review (in contrast with the harmonised classification according to CLP Regulation) and adverse effects were observed on endocrine organs. Therefore, according to the interim provisions of Annex II, point 3.6.5 of Regulation (EC) No 1107/2009 concerning human health, mesotrione may be considered to have endocrine disrupting properties. As no study is available to investigate a potential ED mode of action, a general data gap has been identified such as level 2 and 3 indicated in the OECD Conceptual Framework to address this issue; this was identified as another critical area of concern. The consumer dietary risk assessment could not be finalised with regard to products of animal origin considering the requested clarification of the genotoxic potential and the toxicological profile of AMBA. Furthermore, the consumer risk assessment from consumption of drinking water could not be finalised whilst the nature of residues in drinking water following water treatment had not been addressed. A data gap was also identified for the determination of the residues in pollen and bee products for human consumption. Enough information was available to finalise the exposure assessment in the environment. Nevertheless, a data gap has been identified for the applicant to address the substances of potential toxicological concern that could be derived from mesotrione and its metabolites under drinking water treatment procedure conditions to assess if the approval criteria in Article 4 of Regulation (EC) No 1107/2009 are satisfied. In the area of ecotoxicology, a data gap and a critical area of concern were identified to further address the long-term risk for wild mammals. A data gap was identified to further refine the risk to aquatic organisms in the scenarios R2, R3, and R4. Data gaps were also identified for bees to provide information to further assess the risk to adult honeybees and honeybee larvae from exposure via guttation and via consumption of contaminated water. Effects on HPG development should be considered. Furthermore additional data would be needed to assess the risk to honeybees for relevant metabolites in pollen and nectar. The risk to non-target terrestrial plants was low with mitigation measures. A data gap was also identified to further address the sensitivity to mesotrione of dicotyledonous and monocotyledonous plant species.

78. 植物和草药 ︰ 食物或药物？

潘淑春

Written records of the use of botanicals, herbs, and spices in medicine and food date back more than 5,000 years (Swerdlow 2000). Even as recently as 1890, 59% of the listings in the U.S. Pharmacopeia were from herbal products (Swerdlow 2000). It has been estimated that as many as one-third to one-half of currently used drugs were originally derived from plants (Barrett et al. 1999). According to the World Health Organization, traditional medicine is characterized by herbal remedies, which are the foundation of the present widespread use of traditional medicine in China, Africa, Europe, Southeast Asia, and North America. Egyptian schools of herbalists are said to have existed since 3000 B.C. (Penn State Extension 2016). Two of the identified uses of herbs described in oral history are the use of borage (Borago officinalis), administered to those who needed courage, and rosemary (Rosmarinus officinalis), which was given for memory problems. Despite these interesting healthful applications, it is important to remember that borage oil, a source of γ-linolenic acid, also contains pyrrolizidine alkaloids (Wretensjö and Karlberg 2003). The pharmacology of rosemary is considerably more complex; it is based on caffeic acid and its phenolic derivatives (Al-Sereitia et al. 1999). Adverse events associated with rosemary involve allergic reactions and pulmonary distress. These events are rare, however (Barceloux 2008). A cursory survey of the Internet yields a myriad of articles, blogs, and, of course, marketing and sales websites devoted to botanicals, herbs, herbalism, and herbal medicine. These terms are seen in discussions of Ayurvedic, traditional Chinese medicine, and traditional African medicine and seem consubstantial with declarations of fresh air, rest, and proper diet as the basis for achieving and maintaining health and treating a vast spectrum of diseases. Recurrent themes include the “Doctrine of Signatures,” which suggests that the physical appearance of an herb is indicative of therapeutic use; the notion that plants grown in a certain area tend to cure the diseases afflicting that region; the idea that herbs are “holistic;” and the position that the various whole plant extracts in herbal medicines are superior to the single pure component of a drug since the multiple ingredients enhance therapeutic effect and limit side effects. Throughout world markets, including those in developing countries, species of medicinal plants appear to be playing an increasingly important role; they are abundant, locally available, relatively inexpensive, and consistently associated with safety and efficacy (George 2011). According to a 2008 consumer assessment of herbal product usage, herbal products have gained popularity in recent times and even 10 years ago were used by approximately 20% of the population (Bent 2008). There seem to be almost as many definitions of these apparently simple plant-related terms as there are examples of the plants that they are purported to describe. Ingredients characterized as botanical or herbal appear in teas, foods, tinctures, oils, extracts, syrups, tablets, lozenges, creams, salves, lotions, and poultices. The dose and form of a botanical preparation play important roles in its safety. Teas, tinctures, and extracts have very different strengths. The same amount of a botanical may be contained in a cup of tea, a few teaspoons of tincture, or an even smaller quantity of an extract. Each botanical or herb may contain any stable or variable combination and dose of dozens of compounds such as fatty acids, sterols, alkaloids, flavonoids, glycosides, saponins, and others (Rotblatt and Ziment 2002). Herbs are often perceived as natural and therefore safe, despite the fact that many different side effects have been reported, likely related to varying, unknown, or unstudied active ingredients, contaminants, or interactions with drugs (Bent 2008). Particularly concerning is that the true frequency of side effects for most herbs is not known because most have simply not been tested in large clinical trials and because surveillance systems and compendia of classification such as the German Commission E reports are much less extensive or scientifically substantive than similar works that exist for pharmaceutical products (Blumenthal et al. 1998).

80. Vilsack秘书宣布为学校提供2500万美元的学校食品服务新设备，以帮助学校提高膳食质量

mj

农业部长汤姆维尔萨克今天宣布将提供2500万美元的赠款，用于帮助国家学校午餐计划（NSLP）的运用，为学校提供新的节能设备以替换过时的设备，如冰箱、烤箱和其他食品服务相关设备。这笔资金将根据1966年儿童营养法第7（a）（2）条条例，一次性拨款给国家教育机构。 维尔萨克说：“奥巴马总统和我致力于通过我们的全国学校午餐计划确保美国儿童能够获得安全营养的食物。这些拨款将帮助学校获得急需的基础设施，以更好地为学生服务，并将重点放在帮助学校提供营养餐、支持食品安全工作、提高能源效率和扩大参与学校营养计划的设备上。” 根据该法案的规定，美国农业部的食品和营养服务（FNS）将向参与NSLP的学校食品管理部门颁发这些拨款，并且在2009财年没有获得2009年美国恢复和再投资法案的NSLP设备援助的学校。此外，优先考虑50％或以上学生有资格享受NSLP免费或优惠价格膳食的学校。 “美国农业部的首要任务之一是在上学期间为我们的孩子提供均衡、健康的膳食和小吃，”维尔萨克说。“美国农业部全国学校午餐计划提供的午餐可以帮助孩子们选择健康饮食和生活方式。” NSLP在全国超过101000所公立和非营利私立学校和住宿儿童保育机构开展工作，与FNS的其他营养援助计划协同工作，形成了一个反饥饿的国家安全网。它为所有经济背景的学龄儿童提供均衡、健康的膳食，旨在满足美国人的膳食指南。在某些情况下，学校午餐是有需要的孩子的主要每日膳食。 国会目前正在考虑重新授权“儿童营养法”，该法为全国学校午餐和早餐计划提供了大纲，为超过3100万儿童提供服务。行政重点包括消除阻碍儿童参与学校营养计划的障碍、提高学校膳食质量和学校环境的健康状况，以及提高计划绩效。

李晓妍

美国农业部(USDA)发布了一项拟议中的规则，该规则拟取消当前学校膳食营养标准的重要方面，这一改变将会显著破坏《2010年健康、无饥饿儿童法案》所取得的进展。这一拟议的规则将削弱营养标准，消除所有儿童无论在何种学校环境下都能获得均衡和健康的学校膳食的保证，并降低食堂出售的其他食品的营养价值。学校的膳食理应与美国人的膳食指南相一致，包括在早餐和午餐供应各种水果和蔬菜。 这个考虑不周的提议是特朗普政府废除学校膳食营养标准的关键组成部分的延续，第一个规则于2018年12月定稿，削弱了全谷物、牛奶和钠的标准。 健康的校餐有助于防止儿童肥胖，改善整体健康状况，特别是对低收入儿童。美国农业部自己的研究以及其他研究表明，学校餐改善了儿童的饮食和健康。现在还不是取消营养标准的时候。

潘淑春

This study had the major objective of evaluating the food safety knowledge, attitudes and practices of consumers and vendors of street foods in Ho Chi Minh City (MCMC), Vietnam. There were three main surveys performed in this study. A total of 120 consumers and 40 street food vendors from four districts [Binh Thanh (BT), Thu Duc (TD), district 3 (D3) and district 8 (D8)] in HCMC contributed to the study on a voluntary basis. The surveyed consumers had adequate levels of food safety knowledge and attitudes. No significant difference (p > 0.05) occurred between the food safety knowledge levels of the consumers on the basis of gender. However, significant differences (p < 0.05) occurred on the basis of age, education level, food safety training status and location. In contrast, the street vendors had poor food safety knowledge and attitude levels. No significant differences (p > 0.05) were observed in the food safety knowledge levels of the vendors on the basis of gender and age. However, significant differences (p < 0.05) were found on the basis of food safety training status and education level. It was also noted that the vast majority (95%) of the vendors had not received any food safety training. With regards to the practices, it was determined that 52.5% of the vending sites were open air stands without any protection from the sun, wind and dust. 52.5% the vending stalls had no direct access to potable water, while 47.5% did not have adequate hand washing facilities and a further 30% lacked proper waste water and food disposal facilities. In addition, 52.5% of the vendors did not separate raw, partially cooked food and cooked food products. These findings highlighted that street food vendors in HCMC generally have poor food handling practices and most are operating under unhygienic conditions. These results should provide the Vietnamese government with even more reasons to increase their current efforts to improve the safety of street foods and food safety awareness of the consumers.

84. 全谷物摄入与胰腺癌风险:丹麦、饮食、癌症和健康队列

李晓妍

背景——胰腺癌是一种高致死率且预后不良的疾病。预防这种疾病的知识有限，因此，识别危险因素对降低疾病发生率具有重要意义。 目标——本研究的目的是前瞻性地调查胰腺癌发病率与全谷类食物摄入量之间的关系，测量方法有两种：全谷类食物摄入量和全谷类食物摄入量。此外，还调查了这些食品的亚组摄入量：全谷类食品（黑麦面包、全谷类面包和燕麦片/麦片）和谷类食品（黑麦、小麦和燕麦）。 方法——总共有55995名年龄在50-64岁之间的丹麦成年人参与了这项研究，其中446人患上了胰腺癌（平均随访17.5年）。全谷类食品的每日摄入量的详细信息可从经验证的自我管理FFQ中获得，全谷类食品（小麦、黑麦和燕麦）的摄入量可通过24小时膳食回忆中的信息进行估计。 结果——全谷类食品总摄入量与每份（50 g/d）胰腺癌发病率降低7%相关，在性别特异性分析中，仅在男性中发现相反的关联。未发现与全谷类食物总摄入量相关。当单独调查特定的全麦产品和谷类食品时，没有一种单独与胰腺癌的低发病率相关。 结论——研究结果表明，摄入全谷类食物与中年男性患胰腺癌的风险降低有关。大量食用全谷类食品可能有助于降低胰腺癌风险。

The method of liquid chromatographic tandem mass spectrometry was utilized and modified to confirm and quantify acrylamide in heating cooking oil and animal fat. Heating asparagine with various cooking oils and animal fat at 180 °C produced varying amounts of acrylamide. The acrylamide in the different cooking oils and animal fat using a constant amount of asparagine was measured. Cooking oils were also examined for peroxide, anisidine and iodine values (or oxidation values). A direct correlation was observed between oxidation values and acrylamide formation in different cooking oils. Significantly less acrylamide was produced in saturated animal fat than in unsaturated cooking oil, with 366 ng/g in lard and 211 ng/g in ghee versus 2447 ng/g in soy oil, followed by palm olein with 1442 ng/g.

李晓妍

肥胖是导致许多疾病的主要因素，如糖尿病、心血管疾病和癌症。因此，寻求安全有效控制肥胖的方法至关重要。肠道微生物群通过调节能量代谢在肥胖的发生中起着关键作用。饮食可以改变肠道菌群的组成和丰度，许多膳食植物通过调节肠道菌群的生物活性成分能够发挥抗肥胖作用。在这篇综述中，与肥胖相关的肠道微生物群被归纳与归类为致肥胖和抗肥胖两大类。研究发现，某些菌群与肥胖症发展呈正相关，但大多数乳杆菌和某些拟杆菌属具有抗肥胖作用。一些膳食植物，例如葡萄、苹果、姜黄、辣椒、大豆、高粱和大麦等，通过增加肠道菌群的多样性，上调抗肥胖肠道菌群和下调致肥胖肠道，表现出抗肥胖功效。这篇综述可能会促进通过调节肠道菌群来治疗肥胖症的功能性食品的进一步发展。

niexiuping

全球发育迟缓患病率在1990年至2016年间几乎减半，但这种下降是否有益于低收入和中等收入国家（LMICs）的贫穷和农村人口尚不清楚。我们根据家庭财富和67个中低收入国家的居住地评估了5岁以下（5岁以下）儿童发育迟缓的时间趋势。1993年平均患病率为低收入国家53.7％，中等收入国家为48.2％，年平均线性下降分别为0.76和0.72个百分点。尽管在所有国家中最贫穷的40％和最富裕的60％组别都有类似的下降斜率（分别为0.78和0.74 pp），但低收入国家的绝对和相对不平等程度随着时间的推移而增加（SII从1993年的-19.3％至2014年的-23.7％，而CIX则从同期的-6.2％上升至-10.8％）。在中等收入国家，社会经济不平等保持稳定。总体而言，农村发育迟缓患病率比城市儿童下降更快（分别为0.78和0.55 pp）。发育迟缓的发生率正在下降。中等收入国家贫富差距稳定，低收入国家略有增加。随着时间的推移，城乡不平等正在减少。

这项二次分析旨在评估游离糖摄入量对微量营养素稀释的影响，并根据2011-2012年澳大利亚健康调查的数据估计游离糖摄入量的阈值水平，在此水平下微量营养素摄入量的下降变得明显。分析了完成两次24小时召回的成年受访者（加权n = 6150）的膳食数据。采用了已发布的10步法，并用于估计受访者的游离糖摄入量。观察到大多数微量营养素的峰值摄入量在5％和<15％之间，％EFS。观察到大部分微量营养素摄入量在EFS> 25％时显着降低。在EFS <5％时，一些微量营养素摄入量减少。当EFS％在5％和25％之间时，仅观察到微量营养素消耗的微小变化。随着游离糖摄入量的增加，核心食物摄入量减少，酌情食物增加。发现高游离糖摄入量，特别是> 25％的EFS对大多数营养素具有显着的稀释作用。然而，EFS <5％的游离糖摄入量可能会增加与总能量摄入不足相关的微量营养素摄入量过低的风险。

92. 营养调控：共轭亚油酸在脂肪组织中的炎症和褐变特性

lixiaoman

肥胖是当今美国最普遍的营养疾病，因此制定有效和安全的战略来管理多余的脂肪是非常必要和重要的。其中减轻肥胖的一个有效策略是消耗共轭亚油酸（CLA）的含有补充剂的异构体，cis-9, trans-11和 trans-10, cis-12或者仅仅是 trans-10, cis-12。提出了利用共轭亚油酸来减肥的机制，包括调节脂肪细胞脂质代谢、类脂（化合）物代谢作用、炎症、脂肪细胞凋亡、褐变的脂肪组织以及能量代谢。然而，机体丢失脂肪的介导反应与共轭亚油酸的因果关系，特别是炎症、发热和能量代谢之间的联系还尚不清楚。本文主要探讨共轭亚油酸的减肥特性主要是由于炎症信号还是共轭亚油酸与脂肪分解，产热，和白、棕色脂肪组织褐变的联系。我们提出了一系列的问题来研究调节共轭亚油酸减肥特性时对交感神经系统的作用。

93. 关于时间：进食时机是肥胖的一个复杂风险因素

李晓妍

进食频率和进食时机的话题是目前大众媒体中患者和公众热衷的营养话题“热点”。虽然人们普遍认为这一话题已经得到了充分的研究，但由于缺乏合适的研究，官方的、基于证据的建议还没有开发出成人一天中应该多少次或多少时间吃正餐、零食和喝高热量饮料。到目前为止，大多数营养学研究都只关注吃什么，而不是什么时候吃。在本期《美国临床营养学杂志》上，Dashti等人在他们的论文中填补了这一空白，题为“晚食与心脏代谢风险特征、致肥行为和减肥障碍有关。” 据统计，与早食者相比，晚食者有更高的几率出现减肥障碍、有压力时吃东西、晚上暴饮暴食、边看电视边吃东西。在饮食时间和肥胖之间的关联中，许多因素之间的关系的优势和方向需要在多个不同的人群中进行进一步的纵向调查，包括社会经济因素。 报告显示，在北美成年人中，晚吃、吃零食和不吃早餐的习惯正在增加。随着伪科学和毫无根据的饮食建议越来越多，人们很容易受到没有证据的潜在危险的饮食建议的影响。因此学界需要更多关于进食时间的研究，如Dashti等人进行的研究，以确定进食时间是否为一般人群更健康的生活方式和更好的患者风险管理的干预目标点。

94. 肠道菌群在蛋白质代谢中的作用及与健康相关的结果：正反两方面

panshuchun

Scope and Approach This review provides an up-to-date description of the dominant pathways/genes involved in amino acid metabolism in gut bacteria, and provides an inventory of metabolic intermediates derived from bacterial protein fermentation that may affect human health. Advances in understanding bacterial protein fermentation pathways and metabolites generated at a global level via the implementation of ‘omics’ technologies are reviewed. Finally, the impact of dietary protein intake and high-protein diets on human health is discussed. Key Findings and Conclusions The intestinal microbiota is able to synthesize amino acids, but the net result of amino acid production and utilization, according to dietary patterns still needs to be determined. The amount of ingested dietary protein appears to modify both the diversity and composition of the intestinal microbiota as well as the luminal environment of the intestinal epithelium and peripheral tissues. The understanding of the consequences of such changes on the host physiology and pathophysiology is still in an early stage but major progress is expected in the near future with the investigation of host-microbe omics profiles from well-controlled human intervention studies.

99. 欧洲基线调查牡蛎诺如病毒的技术规格

潘淑春

The European Commission requested scientific technical assistance in the preparation of a survey protocol for a European Union (EU) coordinated monitoring programme on the prevalence of norovirus (NoV) in raw oysters. The objective of the survey is to estimate the European prevalence of norovirus-contaminated oysters at production areas and batches of oysters at dispatch centres, with a 95% level of confidence and a level of precision of 5% considering an expected prevalence of 50%. The survey protocol defines the target population, the sample size for the survey, sample collection requirements, the analytical method for the quantification of NoV copy number (genotype I and genotype II), the data reporting requirements and the plan of analysis. The sample unit in production areas is a classified production area actively growing commercial oysters (whether harvesting or not is occurring) and for dispatch centres is a quantity of live oysters which are being packed and labelled with an Identification Mark. Based on a multistage sampling scheme, 1,026 samples from 171 production areas and 1,182 samples from 197 dispatch centres should be taken annually in Europe. To reduce the probability of surveying an atypical year, the survey is to be repeated for a second year. The samples are to be analysed according to the method specification developed by the European Union Reference Laboratory (EURL) expert working group, which is compliant with ISO/DIS 15216-1. Generalised linear models will be used to estimate proportion (with 95% confidence intervals) of sample units with NoV contamination for the following thresholds: < limit of quantification (LOQ), 100, 200, 500, 1,000, 5,000, 10,000 and > 10,000 copies/g. The necessary data to be reported by the sampler and the laboratory to support this analysis is presented in two data models. The results of the survey should be reported using the EFSA data collection framework.
