Food that Contain Cysteine and Methionine

Amino acids are the building blocks of protein. When we eat protein foods our bodies break down the proteins into their respective amino acids, and then builds them back up into new proteins that help build muscle and organs and help run other functions in the body. The amino acids cysteine and methionine are needed by the body as well, and can be gotten from certain foods.

Benefits of methionine amino acid

Methionine is a sulfur-containing and proteinogenic amino acid. It provides sulfur for the hair, skin, and nails plus lowers cholesterol and provides protection for the kidneys. It can also prevent liver damage from taking too much acetaminophen (Tylenol).

Methionine can increase acidity in the urine, improve wound healing, and treat various liver disorders. Other uses for methionine include treating copper poisoning, alcoholism, depression, allergies, asthma, side effects from radiation, drug withdrawal, schizophrenia, and even Parkinson’s disease.

Benefits of cysteine amino acid

Cysteine helps protect the liver against long-term effects of alcohol use, specifically from the poison acetaldehyde (a by-product of alcohol metabolism), although it does not reduce drunkenness. Cysteine is also an antioxidant and therefore fights free radicals in the body. It can help with treating diabetes, colitis (an inflammatory bowel disease (IBD), plus may treat cardiovascular disease, angina, flu, chronic bronchitis, inflammation, and osteoarthritis.

This sulfur-containing amino acid is synthesized only when methionine is in the body, therefore it is connected to methionine in this way and is why both cysteine and methionine are usually taken together through dietary supplementation. This is why it is important to eat foods that contain both cysteine and methionine so that they can complement one another for proper health benefits.

Foods high in cysteine and methionine

Methionine and cysteine work in tandem in the body, with cysteine particularly being dependent upon the presence of methionine to be produced and work in the body.

Branched-Chain Amino Acids (BCAA) Help Liver Patients

Supplements containing branched-chain amino acid (BCAA) granules improved the outcome for patients with liver disease.

Liver cirrhosis is caused by advanced liver disease. The liver tissue is gradually replaced with scar tissue, resulting in a loss of liver function. This loss of liver function causes fluids to be retained in the abdominal cavity, leading to massive swelling and greatly reducing quality of life.

Liver cirrhosis can also lead to esophageal varices, which are dilated veins in the bottom of the esophagus. The dilated veins are formed when the blood flow through the liver is disrupted due to liver scarring. These veins often bleed, and must be treated with endoscopy.

The cirrhosis and complications results in lack of nutrition for the patient, as nutrients cannot be properly absorbed. Nutritional supplements are therefore part of the treatment.

An article in J Gastroenterol investigated the benefits of branched-chain amino acid enriched nutrients for patients with liver cirrhosis.

Branched-chain amino acids (BCAA’s) are essential amino acids, which mean we must get them from our food. BCAA’s are crucial to our wellbeing, as they not only create the antibodies which fight infection, but also make up our muscles and internal organs.

Sakai Y, Iwata Y, et al, researchers at the Hyogo College of Medicine, Japan, investigated the usefulness of BCAA supplements for liver patients undergoing endoscopic treatment for esophageal varices.

BCAA-enriched nutrients improve outcome for liver patients

The researchers gave patients BCAA-enriched nutrients, and evaluated their nutritional status over time. They examined weight gain and albumin on the first day, day seven, and day 50.

The BCAA-enriched nutrient mixture maintained the weight in the cirrhotic patients. Their non-protein respiratory quotients were also significantly improved.

The researchers concluded that including BCAA’s with nutritional energy supplements would be beneficial for cirrhotic patients undergoing endoscopic treatments.
