science π§ Sweet stuff fueled human brain growth, scientists find
New research suggests naturally-sweet foods significantly powered human brain evolution over millennia. Scientists from the University of Sydney and Glasgow modeled glucose needs across 4 million years of human development. During this time, the brain grew from 300 grams to an average of 1.5kg, increasing glucose demand. These findings challenge old ideas, pointing to early reliance on fruit-based carbohydrates instead of just meat. Researchers now advise prioritizing high-quality carb sources like fruit and legumes in diets. π§
