soy and its products

Children grow rapidly, which is why their bodily demands of proteins must be met adequately. Amino acids like Lysine are essential as they cannot be synthesized in the body, and are assimilated only from Lysine Rich Foods. Lysine’s role in the body is not limited to growth; it also helps in production of carnitine (nutrient responsible for converting fatty acids into energy and helps lower cholesterol), calcium absorption, and formation of collagen (bones, connective tissue, skin, tendon, and cartilage). Lysine deficiency in children can cause severe growth impairment. Symptoms of deficiency are nausea, fatigue, dizziness, loss of appetite, slow growth, agitation and anemia. Children who eat a protein rich diet rarely suffer from lysine deficiency


The current Recommended Dietary Allowance (RDA) is based on a factorial, but to make it simpler for you it is recommended that children between 2 to 12 yrs are given 23 mg of lysine per kg or 10 mg per pound of body weight daily


Food Sources of Lysine

The best sources of lysine are “protein rich foods” like red meat, pork, poultry, eggs, and fish, cheese, nuts, soy and its products, spirulina, brewers yeast,  legumes, nuts, beans, and dairy products. Some foods like strawberries, oranges, banana, apples, spinach, kale, broccoli, and carrots are also good sources.
