The Role of Fermentation in Human Brain Evolution

Recent research suggests that fermentation, rather than cooking, played a crucial role in driving the evolution of the human brain. The consumption of pre-digested, fermented foods provided more accessible nourishment, bridging the gap between the growth of larger brains and the later advent of cooking. This hypothesis is supported by evidence such as the smaller large intestine in humans compared to other primates, indicating adaptation to easier-to-digest foods. Exploring the impact of fermented foods on human health and the gut microbiome could potentially link it to both physical and mental well-being.
