Food sources of arginine

Arginine, a benign amino acid, increases nitric oxide; in high doses it acts as a vasodilator.

The average American generally ingests up to 5.4 g of L-arginine per day through foods. This amount is generally more than adequate to serve as a substrate for nitric oxide synthesis.

The richest sources of arginine are found in vegetable protein.

Nuts especially peanuts are the best source of arginine, an amino acid that plays and important role in wound healing, detoxification reactions, immune functions, and promotion of the secretion of several hormones, including insulin and growth hormone. Peanuts contain 3 g arginine per 100 g.

Food sources other than nuts are including meats, seafood, eggs, dairy products, chocolate, and gelatin. 

Arginine is high in oats, wheat and rice than other amino acids.
