Sugar's Role in Human Brain Evolution

A study published in Science challenges the traditional view of early human diet, highlighting the significance of sugar from fruits and honey in the growth and evolution of the human brain. The review suggests that, for millions of years, sugar was the primary source of glucose for early hominins, meeting the high energy demands of the brain and reproductive organs. The study also discusses the dietary transitions and food acquisition methods that may have driven complex food-seeking behaviors and influenced genetic selection.
