What Humans Should Eat

I've been inundated with dietary data ever since I first took a course in food chemistry about 20 years ago. Back and forth the dieticians go, muttering about what should be low.

But I've noticed some interesting points in all the data.

1. Try to eat food in its natural state; unless the food is bad or is carrying a bacterial load, raw food is fine.
2. Try to eat whole foods. A complete fruit is normally better than an extract from it, even if that extract is Vitamin C.
3. If you feel full or you don't feel like eating anymore, go with the feeling.
4. If the food source looks unnatural compared to natural variants you've seen before, don't eat it.
5. Fat is often better than sugar, just as whole grains are better than wholemeal (or instant cereal, or flour); the slower your body processes energy foods, the better they are.
6. You need a whole lot less protein than you think you do.
7. Leaves and berries are good, so salad leaves and coffee are great.
8. The only treatment that consistently extends life in mammals seems to be calorie reduction.

Afterthought: is it only me, or does nobody notice that besides humans, no other animal in existence likes to eat burnt food?
