Protein is a macronutrient necessary for the proper growth and function of the human body. There is considerable debate over the amount of protein a person needs to consume per day, the current recommended daily intake (RDI) for protein is 46 grams for women aged 19-70, and 56 grams for men aged 19-70. Any excess protein is turned into energy by the body, and it is controversial whether this excess protein causes a strain on the liver.
A deficiency in protein intake leads to muscle atrophy, inability to build muscle,and impaired functioning of the human body in general.
High protein foods include meat, fish, cheese, tofu, beans, lentils, yogurt, eggs, nuts, and seeds.
