A lot of the “food” that people eat could barely be classified as such. I will admit that people throughout history have eaten a huge variety of items, but they were based on natural substances. Not the “all natural” marketing term presently in use, but organic ingredients free of industrial chemicals and byproducts. Now that our food is full of synthetic chemicals (many of which have unknown side effects), it’s not the same.
Thanks to Fir0002 for the nuggets.
