“The reason behind the fortification program was to bring our nutrient intake to a reasonable place, and it targeted nutrients that we were lacking,” Dr. Vitolins said.

“食物强化项目的目的是把营养素摄入提高到合理水平，针对的是人们当时缺乏的营养素，”维托林博士说。

Early on, fortification was limited to a few select foods, in part so the program would not create nutritional imbalances. In an attempt to prevent indiscriminate fortification, the Food and Drug Administration proposed restricting the number of foods that could be fortified to eight, and it specified which nutrients could be added.

在早期，营养强化仅限于几种精选的食物，部分目的在于防止该项目造成营养失衡。为了防止任意强化，美国食品和药物管理局提议将能强化营养的食物限制在八种以内，还具体指明可以添加哪些营养素。

But that proposal was shot down in the 1970s, and over the years Congress went on to restrict the F.D.A.’s authority over fortification and dietary supplements. This helped open the door to the eventual explosion of vitamin enhanced beverages and sports drinks, which today account for sales of more than $18 billion a year in the United States alone.

但是该提议在20世纪70年代被否决，这些年国会进一步限制食品和药物管理局对营养强化和膳食补充剂的管辖权。这最终导致维了生素强化饮料和运动饮料的激增。如今，这些饮料单在美国的年销售额就达180多亿美元。
