some

peopleare making themselves sick trying to get healthy.

至少有一个关于脂溶性维生素的例子—维生素A—人们在试图

(使用它)让自己变得健康的时候却反而使自己生病了。

Because the liver storage is large and is released very slowly

megadoses over time are unhealthy, even deadly.

间的推移大剂量的维他命A是不利于健康,甚至致命的。

Although there are wise uses of moderate increases of

certain vitamins,there is also abuse .

象)。

megadoses are included in listed amounts of

substances that

advocates of large supplementation tell us we must have .

The public press constantly reminds us that food

harvesting ,storage ,and processing methods are producing

“empty calorie “vegetable ,not “half as nutritious as the ones

our grandparents ate .”

nutritions we need today .那些自称为的营养"专家"的人告诉我们即
