Sugar, Not Just Meat, Fueled Growth of Human Brain, New Study Argues
Sugars from fruit and honey, not just meat, likely provided the glucose essential for fueling the growth of increasingly large human brains over 4 million years of evolution. Pregnant and breastfeeding females required significantly more dietary carbohydrates than adult males, suggesting that sugar availability may have directly shaped reproductive success and survival.
