From Arctic peoples in Siberia, Scandinavia, Northern Canada, and Alaska, to nomadic peoples of Mongolia and Caucasia, the pastoral Maasai, and Indigenous people of the Great Plains, many recent thriving cultures ate traditional diets of primarily meat, with plants used infrequently, or in small quantities, or mostly for medicinal purposes. This contributes to our understanding that not all healthy diets need include large quantities of fruits and vegetables.
