The Claim
The evolutionary expansion of the human brain was driven by dietary intake of animal-derived fats and cholesterol.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A long time ago, as human brains got bigger, it might have been because our ancestors started eating more meat, eggs, and other animal foods rich in fats and cholesterol.

Evolutionary expansion of the human brain was driven by dietary intake of animal-derived fats and cholesterol.
What the research says
1 studyStudy: A brief history of meat in the human diet and current health implications.
The study shows that when early humans started eating more meat and animal fats, their brains got bigger—so yes, animal fats and cholesterol likely helped our brains grow.
