A new study in the Journal of the Academy of Nutrition and Dietetics, published by Elsevier, has determined that 60% of foods purchased by Americans contain technical food additives including colouring or flavouring agents, preservatives and sweeteners. This represents a 10% increase since 2001. The findings also present evidence that the prevalence of food additives is on the rise; manufacturers have increased the mean number of additives contained in purchased food and beverage products from 3.7 in 2001 to 4.5 in 2019.

爱思唯尔发表在《营养与饮食学会杂志》上的一项新研究表明，美国人购买的60%的食品含有技术食品添加剂，包括着色剂或调味剂、防腐剂和甜味剂。这意味着自2001年以来增长了10%。研究结果还表明，食品添加剂的使用率正在上升；制造商已将食品和饮料中的平均添加剂数量，从2001年的3.7种增加到2019年的4.5种。

While food additives can extend shelf life and improve palatability, their health consequences are not fully understood. Assessing food-additive exposure over time is a vital step in understanding its potential role in some adverse health outcomes.

虽然食品添加剂可以延长保质期和改善口感，但其对健康的影响尚未完全了解。评估长期接触食品添加剂，是了解其在某些不良健康后果中的潜在作用的重要一步。

“Our research clearly shows that the proportion of ultra-processed foods with additives in Americans’ shopping carts increased significantly between 2001 and 2019. We observed this trend across all food and additive categories,” noted lead investigator Elizabeth K. Dunford, PhD, Food Policy Division, The George Institute for Global Health, University of New South Wales, Sydney, Australia, and Department of Nutrition, Gillings Global School of Public Health, The University of North Carolina at Chapel Hill, USA.

作为澳大利亚悉尼新南威尔士大学乔治全球卫生研究所食品政策部门的博士，以及美国北卡罗来纳大学教堂山分校吉林斯全球公共卫生学院营养系的博士，首席研究员伊丽莎白·k·邓福德博士指出，“我们的研究清楚地表明，在2001年至2019年间，美国人购买含有添加剂的超加工食品的比例显著增加。我们在所有食品和添加剂类别中都观察到了这种趋势。”

By 2019, more than half of the overall packaged food and beverage products bought by US households contained three or more additives. Furthermore, a 22% higher percentage of baby food purchases were ultra-processed and contained additives.

到2019年，美国家庭购买的包装食品和饮料中，超过一半含有三种或三种以上的添加剂。此外，购买的婴儿食品中超加工和含有添加剂的比例高出22%。

“These findings give us reason for concern, given the growing evidence linking high consumption of processed foods with adverse health outcomes,” Dunford noted, adding that the investigators observed one positive trend, a decrease in the use of added flavours in carbonated soft drinks.

邓福德指出：“鉴于越来越多的证据表明，大量食用加工食品与不良健康结果有关，我们有理由为此感到担忧。”并补充说，调查人员观察到一个积极的趋势，即碳酸软饮料中添加香料的使用减少。
