L-Lysine Foods

It is important to incorporate l-lysine foods in our daily diet, because l-lysine is important for the growth and development of our body. Since l-lysine is an essential amino acid it needs to be furnished to the body from food sources or supplements.
L-lysine is one of the eight essential amino acids in the body. Essential amino acids are those amino acids that are not produced within the body and need to be supplemented to the body from food sources or supplements. They are essential because they form building blocks of the body, required for growth and development of our body. Lysine particularly helps in collagen formation, required for healthy bones, cartilage, skin and tendons. It is also required for formation of enzymes and antibodies in the body. Moreover, l-lysine is an effective treatment for herpes, cold sores or fever blisters, by curbing growth and replication of Herpes Simplex Virus. Thus, l-lysine intake is quite essential for our body. There are some l-lysine foods which when consumed, furnish our bodies with l-lysine amino acid.

L-Lysine Deficiency

L-lysine deficiency is not a common problem seen to affect people. Mostly, older folks are seen to have this deficiency as compared to young people. Moreover, since l-lysine is found in eggs, meat and poultry, non-vegetarians are not commonly seen to be affected by lysine deficiency. Vegans are mostly seen to be affected by lysine deficiency. It is important to treat the deficiency as soon as possible, because the deficiency can interfere with carnitine synthesis, thereby having a major impact on fat metabolism. Moreover, since lysine is important for calcium absorption, lysine deficiency can increase the risk of getting osteoporosis. The symptoms of l-lysine deficiency are as follows:
  • Loss of appetite
  • Bloodshot eyes
  • Fatigue
  • Nausea
  • Anemia
  • Reproductive disorders
  • Agitation
  • Dizziness
  • Slow or retarded growth
  • Kidney stones
People with lysine deficiency should consume lysine-rich foods, which will elevate the levels of this essential amino acid in the body.

L-Lysine Foods

Here's a list of foods high in L-Lysine that need to be included in our daily diet, to furnish the body with lysine:
  • Milk
  • Yogurt
  • Cheese (Parmesan cheese)
  • Brewer's yeast
  • Eggs
  • Fish (Cods and sardines)
  • Red meat
  • Pork
  • Chicken
  • Lamb
  • Turkey
  • Soy products
  • Fenugreek seeds
  • Parsley
  • Pears
  • Mango
  • Figs
  • Peaches
  • Papaya
  • Apricots
  • Bananas
  • Apples
  • Celery
  • Peas
  • Pumpkin
  • Tomatoes
  • Avocados
  • Beets
  • Potatoes
  • Lima beans
  • Legumes
  • Nuts (cashew nuts, almonds, Brazil nuts)
Of these l-lysine foods, red meat contains the highest amount of l-lysine. On the other hand vegetables are poor l-lysine food sources, except legumes which contain quite a high amount of l-lysine. However, toasting or roasting legumes causes lysine levels in them to reduce considerably, because lysine is sensitive to effects of food processing such as dry heat. Thus, for vegans, especially those with lysine deficiency, lysine can also be obtained by taking lysine supplements. Let's find out more about them!

Deficiency or no deficiency, we all need to incorporate l-lysine foods in our diet, because lysine is important for growth and repair of the body tissues. Lysine is beneficial for the skin and bones as well. Consuming a healthy, well-balanced diet and maintaining a regular exercise regime is the secret to healthy living!
