The importance of Lysine

Lysine is one of the essential amino acids in human body, which can promote human development, enhance immune function, and improve the function of central nervous system.

Lysine is a basic essential amino acid. Because the content of lysine in cereal food is very low, and it is easily damaged and lacking in the process of processing, it is called the first limiting amino acid.

Symptoms of lysine deficiency include fatigue, weakness, nausea, vomiting, dizziness, loss of appetite, growth retardation, anemia, etc. Lysine nutritional supplements can be taken on the advice of a medical professional. The recommended daily intake of lysine is 10 mg per pound of body weight for children and 3000-9000 mg per day for adults.

Common foods high in lysine include fish, most meats like beef and poultry, and dairy products like cheese and milk. The best plant food sources of lysine include soy products, brewer's yeast, some nuts and other legumes.

Lysine is an essential amino acid that must be obtained from the diet because the body cannot produce it on its own. Most intact protein sources such as animal-derived products contain large amounts of this amino acid. Although lysine supplements are available, even people who do not eat animal foods may not need them.

It is easier for people who eat animal-derived foods to get enough lysine. Poultry sources of lysine include chicken and turkey. Beef and pork, as well as lamb and venison, are rich in lysine. Fish and shellfish are also foods high in lysine, such as salmon, sardines and cod. In addition, eating dairy products such as milk, cheese and yogurt can also help to get enough lysine.

Most vegetables and fruits are not complete proteins and contain only small amounts of lysine. But avocados are an exception. Some non-traditional grains are higher in lysine than traditional grains such as wheat. Quinoa and amaranth are non-traditional grains that contain essential amino acids, including lysine.
