7 of the best foods to support your immune system 

Citrus Fruits and Berries

Vitamin C-rich citrus fruits and berries top our immune-boosting list.  The body does not generate this vitamin, which is thought to help develop white blood cells to fight sickness. Vitamin C must be obtained from diet, hence citrus fruits and berries are good sources:

Red Bell Pepper

The immune system also benefits from red bell peppers.  Red bell peppers, which are not citrus fruits, have twice as much vitamin C as citrus fruits, 120 mg, or 200 percent of the RDA per cup.


Our next choice is broccoli. One of the superfoods, broccoli is low in calories but abundant in minerals. Vitamins A, C, and E boost its antioxidant power to fight disease.


Spinach is another immune-boosting superfood. Vitamin C and folate in spinach help the body repair DNA and build new cells. Spinach, like broccoli, is healthiest when cooked briefly, although gentle cooking releases vitamin A and other nutrients.


Next on our immune-boosting list is garlic, another superfood utilized worldwide in cuisine. Allicin and other sulfur-containing chemicals in garlic improve immunity. Add flavor to meals with this low-fat, low-sodium option.

Chicken Soup

Our next dish is chicken soup, a handmade classic with scientific backing. Chicken soup frequently contains vitamins K and C and protein, which boosts immunity. Carnosine, a flu-fighting molecule, is in the soup.


Oysters are unusual, yet they contain immune-boosting vitamin D and C. Zinc, which helps build and activate white blood cells to combat viruses, is found in oysters.
