Suggesting that bambara nut dumplings (okpa) is a better diet for diabetic patients.
2. Bone health
Bambara nuts contain calcium and phosphorus which is essential for healthy and strong bones especially in the elderly.
The nuts also contain lysine – an amino acid commonly found in beans and other protein foods. This amino acid helps the body to absorb more calcium and reduce the loss of calcium in the urine, thereby protecting bone health.

These antioxidants reduce the incidence of heart diseases, boost immunity, and help prevent cancer.
Antioxidants are known to protect the body from harmful food chemicals and toxins.

6. Malnutrition and pregnancy
Barbara groundnuts are a true quality protein food, they provide more methionine (essential amino acid) than any other grain legumes, let alone the standard staple cereals.
The nuts provide 412 kilocalories of energy per 100g of nuts and provide the body with protein, fats, and carbohydrates. It is a rare example of a complete food.
