Like everything else in our bodies, the immune system depends on nutrients to function properly. According to a paper by Simin N. Meydani, PhD, a professor at the Friedman School and director of the Nutritional Immunology Laboratory at the Human Nutrition Research Center on Aging, and her colleagues, mounting evidence suggests ensuring you get adeqate amounts of certain nutrients may help optimize immune function, including improving resistance to infection. Here is what we know so far:
Vitamin E is an antioxidant that protects cells, including immune cells, from oxidative damage. Evidence suggests vitamin E supports optimal immune function. While vitamin E supplementation can increase risk for bleeding and stroke, dietary intake is perfectly safe.
Vitamin E is found naturally in foods like plant oils (especially sunflower, safflower, and wheat germ oil), nuts, and seeds. This vitamin is sometimes added to processed foods like breakfast cereals (check Nutrition Facts labels). Green vegetables, such as spinach and broccoli, also provide some vitamin E.
Vitamin D receptors are found in most immune cells. Adequate vitamin D levels may help maintain the body’s defense against infection.
Zinc is very important in the first line of defence in our bodies. This first line is represented by physical barriers, such as the skin and mucous membrane linings inside the body. Zinc is found in the mucous secretions of the respiratory system and on the surfaces of lungs and throat. It has an antimicrobial effect, so helps to kill inhaled bacteria and viruses before they get chance to take hold. Zinc is also secreted in the saliva and the mucous membranes of the digestive system to kill any ingested invaders.
Do you suffer from acne, stretch marks, white spots on your nails, poor wound healing, poor immunity? Zinc may have something to do with it. Here we discuss Zinc deficiency, causes, symptoms and why zinc is important.
Zinc is an essential trace mineral and is one of the most abundant to be found in the body. It is naturally found in some foods, added to others and also available as a dietary supplement. You have approximately 2-3g with around 60% is in the muscles that support your skeleton and 30% is in the bones. So if nothing else zinc plays an important part in keeping you upright. The remaining 10% is found in the teeth, hair, nails, skin, liver, leukocytes (white blood cells), prostate, sperm and testes.
