How much protein is in a banana?

Banana has about 1 gram of protein per 100g. A banana has up to 1.6 grams of protein, which is less than 3% of the required daily intake! Other banana products have some protein as well.

According to the National Academy of Sciences, an adult should consume 0.8 grams of protein per kilogram of body weight daily (2).

This means that a person of 70 kg (155 lb) should consume 56 g of protein a day, while a person of 90 kg (200 lb) should consume 72 g of protein daily.

Additionally, the British Nutrition Foundation suggests the same amount of protein for adults. It is estimated that adult men should consume about 56 g of protein daily and women 45 g (3).

Infants, children, pregnant, breastfeeding women, and athletes have increased demands on protein as well.

Actually, most people consume much more protein than they need. This excess protein may make you gain weight, though.
