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

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

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