Best Foods Rich in Arginine And Their Effects on The Body

Best Foods Rich in Arginine: Arginine, or L-arginine, is an amino acid found in foods such as dairy products, fish, poultry, and other meats. It is the building block of protein.

Some research suggests that foods rich in arginine may benefit health, for example, by relieving chest pain, improving erectile dysfunction, and reducing high blood pressure.

The human body produces arginine, and children need it much to grow and develop. Deficiencies are rare, and most adults get any extra arginine they need from their diet.

In this article, you’ll learn about foods rich in arginine, the benefits of amino acids, and the potential risks.

What does arginine do in the body?

The medical community classifies arginine as a semi-essential amino acid. This means that the body produces it and also absorbs it from foods.

There are three types of amino acids:

  • Semi-essential acids that are produced by the body and absorbed by external sources.
  • Essential acids that are not made by the body.
  • Non-essential acids that are produced by the body and that do not need to be supplemented through absorption.

Babies need to absorb a certain amount of arginine through the diet to support their growth. Adults only tend to what their bodies produce.

However, some adults do not produce adequate amounts of arginine. If they do not absorb enough from the diet, they may develop a deficiency.

According to research published in 2012, problems with blood vessels or the immune system can lead to an arginine deficiency. The authors concluded that more research is needed to determine the supplement’s effectiveness.

The health benefits of arginine

Arginine supplements can boost health in various ways. A study from 2013 suggests that arginine supplementation may improve blood flow in people with uncomplicated diabetes.

Improving blood flow may reduce the effects of many cardiovascular diseases, including coronary artery disease and angina.

However, arginine is not an appropriate treatment for all heart conditions. For example, most doctors don’t recommend taking L-arginine after a recent heart attack.

Arginine may also help treat erectile dysfunction caused by heart problems. For example, if there is a problem with blood vessels that makes it difficult to maintain an erection, a doctor may recommend arginine supplements to improve blood flow.

Arginine may also:

  • Helping the kidneys to work more efficiently.
  • Promote wound healing.
  • Strengthening the immune system.
  • Balance hormones.

Arginine dangers

Some evidence suggests that high levels of arginine can make herpes symptoms worse, leading to outbreaks of cold sores. This is because the herpes virus needs arginine to reproduce.

Absorbing more arginine might also indirectly cause cold sores by disrupting the balance of arginine and another amino acid called lysine in the body.

Lysine can treat and prevent cold sores, and it shares an absorption pathway with arginine. If more arginine is present, the body may not be able to absorb enough lysine.

People with cirrhosis or low blood pressure should avoid taking L-arginine supplements. These supplements are also not suitable for anyone who has had a heart attack.
