It was 100,000 years before we figured out what to do with fire. Imagine cavemen, sitting in front of a fire, eating raw meat for 100 thousand years.
Good food for free has been the holy grail of foragers since our ancestors first climbed down from the trees.
Acorns were good until bread was found.
I eat like a caveman.
In theory, I stick to how I could eat if I lived a thousand years ago. I take processed foods off the menu, and stick to things I could hunt or gather, with more fruits, vegetables, and nuts - and less meat.
From my experience with wild apples, I can understand that there may be reason for a savage's preferring many kinds of food which the civilized man rejects. The former has the palate of an outdoor man. It takes a savage or wild taste to appreciate a wild fruit.
I've tried to eat little shrubs before. We were on an unsupported 20-plus day traverse, following the migration of endangered antelope across the Chang Tang Plateau. We were like, 'Oh, this is what they ate; we should try it.'
Today it is generally accepted that although the earliest humans probably ate some meat, it was unlikely to have played a major role in their diet. Plants would have been a much more important source of food.
