Some of the things that can fight diseases and keep you well are watermelon and spinach. Below are the five foods that boost your immune system:

1. 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.

2. 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.

3. 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.

4. 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.

5. Brocolli

You’ll get plenty of nutrients that protect your body from damage. It has vitamins A and C, and the antioxidant glutathione.
