Vegetable protein
Humans require about 50 grams of dietary protein per day from plant or animal sources. Dietary protein is required to supply nutritionally indispensable amino acids:
- histidine,
- isoleucine,
- leucine,
- lysine,
- methionine,
- phenylalanine,
- threonine,
- tryptophan, and
- valine.
Dietary protein is also required to supply nitrogen for the biosynthesis of nutritionally dispensable amino acids:
- aspartic acid,
- asparagine,
- glutamic acid,
- alanine, and
- serine
as well as other physiologically important nitrogen-containing compounds such as
- nucleic acids,
- creatine, and
- porphyrins. [1]
Vegetable protein intake is inversely associated with blood pressure.
