If one were faced with starvation, then seeking out fat as we discussed before, is a pretty good idea, but if one is not deprived of calories, then having fat may not be so helpful.

如果一个人面临饥饿,像我们之前讨论的去寻求脂肪,是个好主意,但是如果一个人不消耗热量,那么摄取脂肪就没什么用了

Fat is not all that much different, but one thing that's happened is the type of fat has changed a lot, and so people are eating less fat from plant sources and more fat from animals sources That's where the saturated fat comes in and high saturated fat intake is not a good thing.

脂肪摄入量相差无几,然而脂肪的种类却发生了很大变化,人们越来越少从植物中摄取脂肪,而更多是从肉类食物中获得,肉类食物中含有饱和脂肪酸,而过多地摄入饱和脂肪酸是有害的
