The ancestral brain and joint food of Yoruba medicine — African walnut seeds boiled and eaten as street food, snack, and medicine throughout West Africa.
Asala is a Yoruba street food sold throughout Lagos. In the US diaspora found in African grocery stores. Its association with intelligence and brain health is embedded in Yoruba proverb.
African walnut has the highest omega-3 ALA content of any West African food — comparable to flaxseed (31-45% of fat as ALA). ALA partially converts to EPA and DHA, driving the anti-inflammatory pathway relevant to hypertension, arthritis, and cognitive protection. Selenium content supports thyroid function and glutathione peroxidase. Multiple Nigerian studies confirm blood glucose reduction in animal models. Tannins provide astringent and anti-diarrheal effects.
Sold boiled in West African markets and African grocery stores. Purchase pre-boiled (in shell or shelled). Eat as a snack directly. Can also be roasted. Do not eat raw — significant tannin astringency.
