What Foods Boost Immune System


Fighting colds and flus doesn't have to be a yearly experience when you eat the proper foods. Explore some particular superfoods that actually boost your immune system and keep you healthy.

Your immune system is always ready for a fight as foreign cells enter your body on a daily basis. White-blood cells lead the charge as they try to balance the body into a healthy homeostasis. As you grow older, however, fighting off germs becomes difficult. There are some foods that you can eat, which will strengthen your immune system through enhanced vitamin resources.

Orange-Colored Produce

Molecular compounds called carotenoids are found in produce that's bright orange. Keep a healthy stock of sweet potatoes, carrots and squash in the house because the carotenoids within each of these items turns into vitamin A as the digestive system breaks them down. Your body uses this vitamin in an antioxidant capacity, which fights off infection as foreign cells invade your body. Other produce, such as pumpkin, is also rich in carotenoids. Simply look for colors as you shop, and adding vitamin A to your diet will be simple.

Oysters

Oysters can be a secret weapon against sickness because they hold countless nutrients. Their main offering is zinc, which tends to calm inflammation down. When the body becomes inflamed, certain areas are so swollen that fighting off infection is often difficult. By reducing the inflammation, zinc allows the immune response to be more centralized to the foreign body. You also gain omega-3 fatty acids, protein and calcium from oysters. All of these essential nutrients improve the body's response to germs as it recovers from almost any sickness.

Citrus

Although no foods can actually prevent sickness, citrus comes close to that ultimate dream. The vitamin C hidden within this food helps the body form defenses against invading germs. Scientists don't know exactly how vitamin C works for the immune system, but it seems to boost white-blood cells' strength against colds and flus. Try oranges, lemons and limes in your daily diet in order to achieve the best effects.

Bananas

Vitamin B6 and potassium are both found in bananas. The vitamin alone is reason enough to eat at least one banana each day because it helps your body with hundreds of critical biochemical reactions. With cells that can react with ferocity, those invading germs can be killed off before they reproduce into huge numbers.

Chicken

Get your fill of lean chicken cuts because they're rich in iron. This element is crucial to oxygen transport around the body. Without oxygen permeating your tissues, the immune system becomes weakened and allows germs to invade. Consider a chicken-based meal twice a week in order to gain the most iron out of this cut.

If fresh foods are hard to find at certain times of year, head toward the freezer aisle at the local grocery store. Frozen fruits, meats and vegetables have the same nutritional values as the items in the produce or meat sections. By being creative with your eating habits, the immune system can win out against almost any invader.
