Diet advice is always in a flux. I have seen dietary advice from experts vary wildly over the years since I was at Uni studying clinical nutrition. They have varied widely and have been influenced by the research of the day. In analysing these various diets for potential benefit I have always applied a simple test, would this diet have been possible when humans were wild and in the development phase? The answer has often been no. Attempting to feed a lion hay will not work out for the lion or the presenter of the hay, who might have to run very fast to avoid becoming an preferable lion snack. Animals are healthy when they eat what they ate in the wild. Zoos spend a lot of money providing the correct diet or the animal with get sick and die. There is a lesson in that! Our poor cute Koalas only eat the leaves from one tree. This is not proving ideal for their survival. We, on the other hand can eat everything almost, except grass. So for us it is a matter of what is optimal and hopefully enjoyable. The question is, what did humans eat in the wild? Go back in time to before our control of fire and weapons (not for creationists this section). Then it gets interesting because although we will never know what we really ate I think some wily deduction may narrow down what our food options were. Two legs are outrun by pretty well everything with four, even the lowly Chihuahua may beat Usain Bolt in a race. So are we going to roam around out on the plain where everything has four legs and there are a lot of meat eating predators? Not so likely. We would hang around water supplies and have escape plans up trees or into caves very close by. Would we be able to drop out of our tree onto a bullock and pummel it into submission or sink our tiny teeth in its neck prior to eating the meat raw? Not so likely. Unfortunately, I think we ate meat only when something big got killed nearby and there were bones left to scavenge or if we could catch something small. Small things aren’t easy to catch so what else? Eggs people. Eggs are up trees and up cliffs where the safety also is. I think we ate all sorts of eggs. Several years ago eggs had cholesterol in them so eggs were limited from a low cholesterol diet. Running this by my Paleo test at the time I decided the diet removing eggs was likely to be wrong. A few years later I saw the results of an experiment where the blood of a man who was eating 20 eggs per day to bulk up in muscle building was tested before and after his egg eating for cholesterol levels. The unexpected result for the researchers was his cholesterol went down. The other type of protein which is always in gay abundance is that of insects, lizards and worms. We have seen our indigenous people eating this gear when living off the land and we are happy to head for the supermarket and buy a packet of cheezels. Stranded in the outback however, they survive and we don’t.
