Acha (Fonio): 7 Amazing Health Benefits and Nutrition

Acha (Fonio) scientifically known as Digitaria exilis is a neglected superfood that has grown in West Africa for over 5000 years.

It is a tiny grass-plant belonging to the Gramineae family and is one of the world’s oldest best cereal.

This wonder grain also commonly called hungry rice, petit mil, fundi grain, and fonio rice, is high in protein, fiber, and carbohydrates.

Acha (Fonio) contains 7- 9% crude protein. Its protein is high in methionine and cysteine, two important amino acids almost deficient in wheat, rice, barley, and rye.

Fonio has also been shown to contain almost twice as much methionine as that found in an egg. So it’s a highly nutritious grain.

Fonio is commonly called “Hungry rice” because it was believed to be a poor man’s food. But in recent times, the fonio grain is in strong competition with other popular grains like quinoa.

It is the grain exotic in some African countries. It is highly prized and reserved for chiefs, royalty, and special occasions.

The grains are also fondly called “Grain of life” because they mature between 6 – 8 weeks and provide food in the growing season when many crops are still immature to be harvested.

And of the two varieties grown, the white acha (D.exilis) is more popular in West Africa (Nigeria, Ghana, Benin) than the black acha (D. iburu) its other counterpart.
