People are eating these foods to boost their immune system.
You probably know about vitamin C’s connection to the immune system, but did you know you can get it from much more than just citrus fruits? Leafy green vegetables such as spinach and kale, bell peppers, brussel sprouts, strawberries and papaya are also excellent sources.
Like vitamin C, vitamin E can be a powerful antioxidant that helps your body fight off infection. Almonds, peanuts, hazelnuts and sunflower seeds are all high in vitamin E. So are spinach and broccoli if you prefer to increase your intake through meals rather than snacks.
This important vitamin — part of nearly 200 biochemical reactions in your body — is critical in how your immune system functions. Foods high in vitamin B6 include bananas, lean chicken breast, cold-water fish such as tuna, baked potatoes and chickpeas.
For vitamin A, go colorful. Foods that are high in colorful compounds called carotenoids — carrots, sweet potatoes, pumpkin, cantaloupe and squash — are all great options. The body turns these carotenoids into vitamin A, and they have an antioxidant effect to help strengthen the immune system against infection.
Selenium seems to have a powerful effect on the immune system, including the potential to slow the body’s over-active responses to certain aggressive forms of cancer. You can find it in garlic, broccoli, sardines, tuna, Brazil nuts and barley, among other foods.
You can find zinc in oysters, crab, lean meats and poultry, baked beans (skip the kind with added sugar), yogurt and chickpeas. Zinc appears to help slow down the immune response and control inflammation in your body.
