Foods to boost your immune system

Jun 20, 2016

It's not only refreshing. When it's ripe, it's also got plenty of an antioxidant called glutathione. It strengthens the immune system so it can fight infection.

Elder berry

It's an old folk remedy. This fruit is loaded with nutrients called antioxidants, and it may help fight inflammation. In some lab studies, an extract from the berries appears to block flu viruses. But scientists caution that more study is needed. You definitely still need to get a yearly flu vaccination!

Button Mushrooms

They give you the mineral selenium and the B vitamins riboflavin and niacin. That helps you in several ways. If you're low on selenium, you may be more likely to get a more severe flu. Riboflavin and niacin play a role in a healthy immune system.

Sweet Potato

Like carrots, sweet potatoes have beta-carotene. In your body that turns into vitamin A, which mops up damaging free radicals.This helps bolster the immune system and may even improve the aging process.

Berry

Its dark color is a sign that it's got plenty of nutrients called anthocyanins.

There isn't any research that shows acai is good for any specific condition. But in general, antioxidants from foods are a key part of a healthy lifestyle.

Watermelon

It's not only refreshing. When it's ripe, it's also got plenty of an antioxidant called glutathione. It strengthens the immune system so it can fight infection.

To get the most glutathione in your watermelon, eat the red pulpy flesh near the rind.

Low-Fat Yogurt

Probiotics, found in yogurt and other fermented products, may ease the severity of colds. Look for labels that say "live and active cultures."

Also look for added vitamin D. Studies show that people with low vitamin D levels may be more likely to get colds or the flu.

Spinach

You'll find lots of nutrients in this "super food." One of them is folate, which helps your body make new cells and repair DNA. It also boasts fiber, antioxidants such as vitamin C, and more. Eat spinach raw or lightly cooked to get the most benefit.

Tea

Feel free to choose white, green, or black. Each delivers disease-fighting polyphenols and flavonoids. These antioxidants seek out cell-damaging free radicals and destroy them. Caffeinated and decaf work equally well.
