自20世纪60年代初以来，美国食品和药物管理局（FDA）的总饮食研究（TDS）一直在持续进行，以测量食物中各种农药残留、污染物和营养物质的水平，并估计从饮食中摄入这些化合物的量。TDS食品清单和用于估计暴露量的消费量都是基于全国食品消费调查的结果，并定期更新，以反映食品消费模式的变化。最近一次更新是在2003年完成的，使用了与上一次更新（1990年）相同的方法。更新后的食品清单所包含的食品数量（285种）与之前的清单（290种）大致相同。虽然大多数（75%）食物在两种版本中是相同的，但新的清单反映了低脂肪食物消费的趋势。更新的饮食反映出食品消费总量的增加，其中最显著的是谷物和饮料消费的增加。一项比较1990年版和2003年版TDS计算的镉暴露量的案例研究表明，食品清单和消费量的变化对TDS暴露估计的潜在影响。
The US Food and Drug Administration's (FDA) Total Diet Study (TDS) has been conducted continuously since the early 1960s to measures levels of various pesticide residues, contaminants, and nutrients in foods and to estimate the dietary exposures to these compounds. Both the TDS food list and the consumption amounts used for estimating exposures are based on results of nationwide food consumption surveys, and they are updated periodically to reflect changes in food consumption patterns. The most recent update was completed in 2003 using the same methodology employed in the previous update ( 1990). The updated food list includes approximately the same number of foods ( 285) as the previous list ( 290). Although most (75%) foods are the same in both versions, the new list reflects trends in consumption of foods containing less fat. The updated diets reflect an increase in total food consumption, with most notable increases in consumption of grains and beverages. A case study comparing cadmium exposures calculated from both the 1990 and 2003 versions of the TDS demonstrated the potential impact of changes in both the food list and consumption amounts on TDS exposure estimates.
