2. Citrus Fruit
Just like vitamin D, vitamin C is extremely helpful when you need to boost your immune system and increase the white blood cells in your body that help you fight infection.
And there’s no better source of vitamin C than citrus fruit. Consuming lemons, grapefruits, oranges, and even limes on a daily basis will give you a great amount of vitamin C that your body always needs.
Speaking of vitamin C, cauliflower is rich in vitamin C, so you know how important adding cauliflower to your diet can be for your immune system.
Not only that, but cauliflower is part of the same family as broccoli, which means they share some of the same properties that can help your immune system.
Finally, cauliflower is a great source of antioxidants, which can protect your cells from inflammation and fiber, which helps your digestive health.
