Make sure you get enough zinc by including crab, oyster and red meat in your diet. Vegetarians especially are at risk of zinc deficiency; however, foods such as whole grains, beans and fortified cereals do contain zinc, so make sure you include these in your diet.

Green leafy vegetables

If you have always eaten green leafy vegetables out of compulsion, here is some news to make you love them. These leaf veggies are a rich source of folic acid which has an important role in the working of the immune system. Studies have found that people with deficiency of folic acid are unable to secrete necessary quantities of antibodies that have infection-fighting properties. Especially if you are pregnant or breastfeeding, make sure you get more of folic acid to supplement your body s increased requirement during these times.

Green Tea

Green tea is a potent source of antioxidants called the polyphenols especially catechins. Some studies have found that these have the ability to destroy the influenza or common cold virus. However, when you have green tea, it is important you leave the milk out because the proteins in milk will bind with the catechins, causing it to lose its antioxidant properties. Adding a little lemon or honey will not have such effects and can even improve palatability. Make sure you only have a few cups of green a day, as this excellent health drink also has side effects.

Foods and products that can weaken your immune system

While all these foods do help to boost immunity, it is also vital to avoid those foods that diminish the immune system s ability to deal with infection. Substances that irritate the inner lining of the stomach alcohol and some drugs such as ibuprofen for example can have the effect of reducing immune system responses and therefore, should be avoided. Several pesticides that are used in growing food contain metals such as lead, mercury and cadmium; if these find a way into your food, they can have a harmful effect on your immunity yet another reason to switch to organically grown foods.
