What Foods Contain Arginine?

Arginine, otherwise known as L-arginine, is an amino acid produced by the body. This amino acid is classified as semi-essential, meaning it assists specific processes in the body, such as getting rid of ammonia and helping with the production of creatine. People with some disorders--including infection, protein deficiency or an excess of ammonia--may not have enough arginine. Normally, however, healthy bodies produce just the right amount.

Nuts

• Nuts contain high levels of arginine. These foods include peanuts, walnuts, cashews, almonds and sunflower seeds.

Proteins

• Animal-protein foods like chicken, tuna, salmon and pork contain arginine.

Dairy

• Dairy products such as milk, cheese and eggs are a significant source of L-arginine.

Other Foods

• Other foods that contain arginine are coffee, chocolate, oats, cereals and soy products.

Warning

• Arginine is offset in the body by an essential amino acid called lysine. Excessive arginine intake can cause or aggravate a cold-sore outbreak; it is important for people with the herpes simplex virus to consume enough lysine while moderating arginine foods.
