The Claim
The evolution of the human brain likely required consistent access to shore-based foods rich in DHA, iodine, and iron, because these nutrients are critical for brain development and are significantly more abundant in aquatic and coastal diets than in inland plant or terrestrial animal sources.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People think our big brains evolved because our ancestors ate lots of fish and shellfish from the shore — these foods have special nutrients that help brains grow, and you can’t get as much of them from plants or land animals.
See the scientific wording
The evolution of the human brain likely required consistent access to shore-based foods rich in DHA, iodine, and iron, as these nutrients are critical for brain development and are far more abundant in aquatic and coastal diets than in inland plant or terrestrial animal sources.
