Foods That Boost Immunity

I just ran across this article on Healthy Eats and thought it was worth passing on.

This winter, protect yourself from those cold or flu bugs going around. Eat more of these fresh foods to build up your immunity.

1) Nuts Snack on almonds, cashews or walnuts, which are packed with vitamin E. This antioxidant helps kick those pesky free-radicals out of your body. Vitamin E also helps create antibodies that fight bacteria that make you sick. Other healthy vitamin E-rich foods are seeds and whole grains.

2) Citrus Fruits The famous vitamin C helps fight infection and a good antioxidant to have — along with vitamin E. But there is more to citrus than just oranges — grapefruits, clementines, lemons, limes and tangerines are all part of this family, and they’re in season in winter so you can enjoy them at their juiciest. Citrus not your thing? Try bell peppers — they have more vitamin C than an orange! Potatoes, tomatoes and kiwi are also great sources.

3) Shrimp So you’ve heard shrimp has cholesterol, but it’s also extremely low in fat and contains the antioxidant selenium. Many foods have a combination of nutrients, and you need to weigh the “bad” with the “good.” Selenium is a mineral needed in small amounts and works to support a healthy immune system. Seafood and meat are great sources for it.

4) Yogurt The probiotics — or “good bacteria” found in yogurt and other foods — keep your digestive system up and running. According to research from the Journal of the American Dietetics Association, consuming foods with probiotics regularly may also help boost your immune system. Sauerkraut, miso and tempeh are other food sources to try.

5) Green Tea The polyphenols in green tea act as potent antioxidants. Research suggests that catechins, a specific type of polyphenol, may stimulate the immune system cells and hinder disease-promoting compounds. Although you may detect a bitter taste, you can disguise it with a bit of honey. Adding milk is a no-no as it will bind to the polyphenols and stop their immunity benefits. (See some of Dana’s ideas on enjoying tea.)

Immunity Downers Eating tons of high-fat foods and forgoing your daily fruits and veggies can also weaken the immune system. Smokers have an added disadvantage as smoking increases free-radicals, which definitely takes a toll on the immune system (another good reason to quit).
