Israeli researchers studying the diet of Stone Age humans say they spent about two million years as hunters. People ate mostly the meat of large animals and rarely anything else.
The authors also pointed to the fallacy of the so-called Paleolithic diet, which suggested that prehistoric humans ate vegetables, fruits, nuts, roots and meat, so these foods are assumed to be the most natural to consume.
In fact, the hypothesis that ancient humans were predominantly hunters has many arguments. For example, scientists studied the acidity of the stomachs and it turned out to be very high. This indicates compliance with the meat diet: acid protects against harmful bacteria.
Researchers believe humans began switching to a plant-based diet about 85,000 years ago, possibly as a result of the decline in the number of large animals.
