Fonio

Fonio, also sometimes called findi or acha, is the term for two cultivated grasses in the genus Digitaria that are important crops in parts of West Africa. It is a vital food source in many rural areas, especially in the mountains of Fouta Djalon, Guinea, but it is also cultivated in Mali, Burkina Faso, Ivory Coast, Nigeria, and Senegal. The global fonio market was estimated at 721,400 tonnes in 2020. Guinea annually produces the most fonio in the world, accounting for over 75% of the world's production in 2019. The name fonio is from Wolof foño. In West Africa, the species black fonio (Digitaria iburua) and white fonio (Digitaria exilis) are cultivated; the latter is the economically more important crop.

Interactions & contraindications

May affect blood sugar

Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)

Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.

May affect blood pressure

Watch for: Antihypertensive medications (ACE inhibitors, beta-blockers, calcium channel blockers, diuretics)

Combined use can push blood pressure too high or too low — monitor readings if you take blood pressure medication.

May thin the blood

Watch for: Anticoagulants (warfarin), antiplatelets (aspirin, clopidogrel), and other blood-thinning herbs or supplements (ginkgo, garlic, fish oil, vitamin E)

Combining blood-thinning substances can increase bleeding risk, including before surgery or dental work.
