New research published in “Science” highlights the crucial role of carbohydrate intake in human evolution and brain development. The study suggests that access to glucose, found in fruits and eventually cooked foods, was a key factor in the expansion of the human brain over millions of years. Researchers found a correlation between increased carbohydrate consumption and neurological advancements in our ancestors. This dietary shift provided the necessary energy for the metabolically demanding brain to grow and function more effectively. The findings challenge previous theories that focused solely on protein and fat as drivers of human cognitive evolution. Ultimately, the research underscores the deep connection between diet and the development of complex cognitive abilities in humans.
