How much protein is in a banana?

Banana has some protein. But, it isn’t the best plant-based food to help us meet our daily protein needs. Even other favorite foods have a higher protein content.

According to the National Academy of Sciences, an adult should consume 0.8 g of protein per kg 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.

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