still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal.
be eaten 是被动用法,我对被动不太了解,有些时候只要用过去式就能表被动,为什么这里要加be?
还是那这个词来说,eat,

先看主动用法:should never eat proteins and carbohydrates 绝不能吃蛋白质与碳水化合物
再换成被动:proteins and carbohydrates should never be eaten蛋白质与碳水化合物绝不能被吃
吃:eat
被吃:be+eaten(eat的过去分词)
纠正一下:过去式和被动是两码事.过去式不能表被动
