7 Foods That Boost the Immune System

Has allergy season got you down? Now more than ever, it’s essential for your immune system to stay in great shape. Let’s take a look at 7 foods that boost your immune system.

Overall, your immune system does a remarkable job of protecting against disease-causing microorganisms. But sometimes it fails: A virus invades successfully and makes you unwell. That’s why it’s essential to know the right resources to support a healthy immune system.


While my little girl may avoid this like the plague, broccoli is loaded with vitamins and minerals. Filled with vitamins A, C, and E and fiber, and many other antioxidants, broccoli is one of the best vegetables you can put on your dinner table.

Sweet Potatoes

Rich in beta carotene (the source of vitamin A), sweet potatoes will be sure to keep you healthy. Plus, vitamin A keeps your skin looking healthy and smooth and protects against UV rays. 

Sunflower Seeds

Sunflower seeds make a tasty supplement to salads or breakfast dishes. They’re also a rich source of Vitamin E, an antioxidant that improves immune function.  


Yes, really! Fish and other seafood are known for high quantities of zinc. There are many zinc-dependent enzymes in our body, and deficiency has been linked with immune dysfunction.   


Don’t let mushrooms intimidate you — they’re perfect for you! Mushrooms are high in selenium and B vitamins like riboflavin and niacin. These minerals and vitamins are necessary for the immune system to work in top shape. Mushrooms are also high in polysaccharides that boost immune function.


Citrus, such as oranges, grapefruits, and limes, are an excellent source of vitamin C. Your body does not naturally produce vitamin C, so it’s vital to get the recommended amount through your diet. 


Are you surprised? Foods that maintain a low-sugar, low-fat diet rich in high-grain are excellent for your immune system. So start the day with oatmeal and some citrus to keep the sniffles away.
