专家称,最令人忧虑的是,市场上出现了大量专门以高含量抗氧化剂为噱头的饮料,比如维他命水(Vitaminwater)、POM Wonderful石榴汁和裸汁果汁(Naked Juice)等。人体需要用抗氧化剂来中和自由基,因为自由基会破坏细胞和DNA。但是专家说,人体也用自由基来对抗传染病和癌细胞,如果抗氧化剂过多,会打破身体平衡。
A study published this month analyzed 46 beverages — both with and without sugar — sold in supermarkets alongside bottled water. It found that many of these drinks contained vitamins B6, B12, niacin and vitamin C in quantities “well in excess” of the average daily requirements for young adults.
本月发表的一项研究分析了在超市里和瓶装水一起售卖的46种(含糖或不含糖的)饮料。研究发现,其中很多饮料的维生素B6、B12、烟酸和维生素C含量“远远超过”年轻成年人的日均所需。
Eighteen of these drinks contained more than triple the daily requirement for B6. Eleven had more than three times the requirement for B12. And a half dozen had more than three times the requirement for niacin or riboflavin. Some of these products promised improvements in energy and immune function, while others promoted “performance and emotional benefits related to nutrient formulations that go beyond conventional nutritional science,” the researchers said.
其中18种饮料添加的B6含量超过日均所需的三倍。11种饮料的B12含量超过日均所需的三倍。六种饮料的烟酸或B2含量超过日均所需的三倍。研究人员说,有些产品承诺能提高活力和免疫力,还有些声称“其营养素配方超越传统饮食科学,能改善身体机能和情绪”。
