Even if caloric restriction extends longevity in people as well as in mice, the extent of the effect remains unclear, though Dr. Weindruch believes the effects will be in the same general range.

即使低卡饮食不仅仅能够延长鼠类的寿命，也能够使人长寿，它的效果依然不确定，虽然Weindruch博士相信效果大致相同。

And the reason is that fructose is toxic beyond its caloric equivalent, so if you consume it instead of glucose you get more of a negative effect even if the calories are the same.

原因在于，在超过了人体的热量平衡之后，继续摄入果糖是有害的，因此即使在卡路里相同的情况下，如果你消耗的是果糖而不是葡萄糖，你就会受到副作用的影响。
