Most root crops have a good quantity of lysine, though less than legumes, while sulphur amino-acids are scarce. For example, yam is high in phenylalanine and threonine but low in cystine and methionine, as well as tryptophan. It also has moderate levels of histidine, isoleucine, leucine, and valine.
Lysine is an essential amino acid that cannot be made by the body and must be consumed through our diet. Most animals consume some form of corn or soybean during their life cycle to provide them with this amino acid. Humans do not have the ability to digest cellulose so instead they eat plants that contain lysine, such as wheat, barley, potatoes, peas, beans, peanuts, alfalfa, clover, and soybeans. Yams are rich in carbohydrates but also contain small amounts of protein, fat, calcium, iron, zinc, and vitamin C.
Because yams are very high in phosphorus and potassium but low in calcium, magnesium, and sulfur amino acids, it's important to include other nutritious foods in your diet too. For example, if you were to eat just one potato you would get about half of your daily value of potassium alone. Also, since yams have more than twice as much phosphorus as calcium, it's important to eat foods with different minerals for better absorption.
Lysine is one of the 20 essential amino acids, which means it must be received from diet because your body cannot make it. Plants and bacteria can both produce lysine from aspartic acid, which is why it is present in green vegetables, legumes, fish, and herbivorous mammals. Humans need to consume lysine to maintain healthy skin, hair, and nails. Lysine helps build strong bones and connects cells together to form tissues.
Lysine is needed for growth hormone production in the body and helps regulate its release so that it occurs at a steady rate. As you get older, your need for lysine increases because your body loses its ability to produce it efficiently. That's why older people usually require more of it than younger ones.
Your body uses lysine when making antibodies to fight infection. This is why people with lyme disease, which is caused by a bacteria called _Borrelia burgdorferi_, have problems producing antibodies because they don't have enough lysine to go around.
Lysine is also needed for making enzymes and hormones. It has other functions too, but these are the most important ones for humans.
People who eat a lot of processed foods may not have enough lysine in their systems. This is because most of the lysine in our food comes from soy products.
Except for peas, fish, poultry, beef, lamb, milk, cheese, beans, brewer's yeast, mung bean sprouts, and most fruits and vegetables have more lysine than arginine. More arginine than lysine is found in gelatin, chocolate, carob, coconut, oats, whole wheat and white flour, peanuts, soybeans, and wheat germ. L-lysine monohydrochloride is used as a dietary supplement to increase the amount of protein consumed. It is available as a powder that must be mixed with water before use.
L-arginine is not stored by the body and thus must be ingested on a regular basis. Although it is present in many foods, including meat, dairy products, and certain vegetables, none of them contain enough of it to meet the needs of an average person. Taking L-arginine supplements may help people who suffer from arginine deficiency syndrome or ARDS. This condition is often associated with severe allergies or asthma and can be life-threatening if not treated properly. Symptoms include shortness of breath, rapid breathing, skin rash, pain when swallowing, confusion, and loss of consciousness.
People who struggle with weight loss should consider adding some arginine-rich foods to their diet. These foods include chicken, fish, pork, eggs, dairy products, nuts, and seeds. Adding these foods to your diet may help you feel full longer which may lead to better control of your calorie intake.
Foods high in protein are good sources of lysine, such as:
The chickpeas (Cicer arietinum L.) Chickpea protein is high in lysine and arginine but low in methionine and cystine, two sulfur-containing amino acids (Manan et al., 1984). Therefore, they are excellent sources of free lysine. The nutritional quality of the seed is further improved by several processing steps that include alkali treatment, heat processing, and acid or enzyme digestion.
Lysine is an essential amino acid. It cannot be made by the body but must be supplied in the diet. Too much lysine can lead to kidney damage. Other harmful effects include skin irritation and an increased risk of developing cancers (especially colon cancer).
Chickpeas are a good source of fiber (20 grams per cup), iron (23% daily value), magnesium (30% dv), phosphorus (24% dv), potassium (38% dv), zinc (12% dv), and copper (8% dv). They also contain calcium (9% dv), niacin (10% dv), and folate (15% dv). One cup of cooked chickpeas has 73 calories, 5 grams of fat, and 9 grams of carbohydrate. They also contain 0.5 gram of protein.
Lycopene may be found in a variety of red and pink foods. Tomatoes and tomato-based meals are the highest sources of this vitamin. Best Food Sources:
L-lysine supplementation is risk-free. A 70-kg male might take 800-3000 mg per day. Doses of up to 3g per day are tolerated satisfactorily. Higher dosages (10–15g per day) might, however, produce gastrointestinal problems such as nausea, abdominal cramps, and diarrhea. Protein intake should be adequate during treatment with lysine.
L-threonine is an essential amino acid that cannot be synthesized by humans. It is found in animal proteins; plants do not contain threonine. Humans must obtain their threonine from their diet because it does not appear to be incorporated into body tissue. Threonine is the only essential amino acid that is not derived from protein sources within the human body. However, since most people get more than enough protein, this step is unnecessary but may be beneficial for those on low-protein diets or who are sensitive to other nutrients present in meats.
L-tryptophan is an essential amino acid that cannot be synthesized by humans. It is found in animal proteins; plants do not contain tryptophan. Humans must obtain their tryptophan from their diet because it does not appear to be incorporated into body tissue. Tryptophan is the only essential amino acid that is not derived from protein sources within the human body.
L-valine is an essential amino acid that cannot be synthesized by humans.
Lysine is an amino acid (protein building block) that is also known by the names L-2,6-diaminohexanoic acid, Lisina, Lys, Lysine Hydrochloride, Lysine Monohydrochloride, and others. It is used as a supplement to feed or treat certain diseases in animals.
L-lysine is used in animal nutrition for the synthesis of antibodies and proteins involved in immune response. It has been shown to prevent illness and reduce mortality from infectious agents such as bacteria, viruses, and parasites. Feeding studies have shown that lysine increases growth rate and yield per unit of feed when compared with animals not receiving lysine.
L-lysine HCl is used in medicine to treat allergies, asthma, chronic bronchitis, cancer, and other conditions where there is need for increased protein production. It is also used as an additive to pig feed to help prevent pigs from contracting pork tapeworm from eating feces contaminated with dog or cat droppings.
L-lysine lactate is used in food supplements to increase the availability of lysine for animals and humans. It can be taken orally or injected into a muscle cell.
L-lysine sulfate is used as a nutritional supplement for animals. It promotes healthy skin and hair, helps build strong bones, and may even have some anti-cancer properties.
