Important Foods That Boost Immune Health


As we all brace ourselves for the true impact of the coronavirus, we need to make sure we do everything possible to keep ourselves healthy and germ-free. In the most basic sense, the pathogen is anything that can create disease and can also be referred to as a germ. Pathogens come in various distinct forms, such as viruses, bacteria, and fungi, and can be conveyed in several distinct ways, such as direct communication with something or someone infected, breathing it in through the air, and coming into contact with the infected bodily fluids.

15 Best Foods To Lower And Control High Blood Pressure

Important Foods that Boost Immune Health

Red Bell Peppers

For people seeking to bypass the sugar in fruit, red bell peppers can be a great alternative source of vitamin C. Stir-frying or cooking both preserve the nutrient content of red bell peppers, better than steaming or boiling. Eat your veggies!


Unsalted almonds are one of the best foods to have around your house or office for a quick, vitamin-rich, immune-boosting meal. Loaded with vitamin E, protein, and healthy fat, almonds are a great alternative for when you’re on the go!

Dark Leafy Greens

Dark, leafy greens are great sources of beta carotene, which is linked with reducing swelling and growing disease-fighting cells, which in turn, helps support your immunity. Since beta carotene converts to the fat-soluble vitamin A, it’s a great idea to pair dark, leafy greens with good fat, like nuts, for best absorption.

Animal Protein

When we think of boosting our immune system, we forget about the power of animal protein. There are many opinions surrounding animal protein and whether it’s good or bad for you. Animal protein is rich in vitamin B12 and vitamin B6, which are key vitamins to the formation of red and white blood cells and strengthening your immune system. There are also two very powerful minerals found in animal protein that will provide immune support—zinc and iron. These proteins will also give the amino acids needed to support neurotransmitters that keep your stress and anxiety levels low. Should you eat it? Yes, but you only need a couple of ounces per day to see some of the positive benefits!

Citrus Fruits

Most people turn straight to vitamin C after they start feeling like they’re coming down with something. It’s my opinion that vitamin C is one of the best ways to improve immune function because of its ability to produce white blood cells, which are key players in fighting off illnesses. One thing to also think about with vitamin C is that your body doesn’t produce or store it, so adding a daily dose is necessary. Almost all citrus fruits are high in vitamin C. Since there is a variety of foods to choose from that offer this powerful micronutrient, it’s easy to add a squeeze of it to any meal. If you wait until you start feeling sick, it might be a little too late. Start incorporating vitamin C into your diet today!


Broccoli is supercharged with vitamins and minerals. Packed with vitamins A, C, and E, as well as fibre and many other antioxidants, broccoli is one of the healthiest vegetables you can put on your plate. The key to keeping its power intact is to cook it as little as possible. Some evidence has shown that steaming is the best way to keep more nutrients in the food.


Blueberries contain a type of flavonoid called anthocyanin, which has antioxidant properties that can help boost a person’s immune system. Some research has shown that flavonoids play an essential role in the respiratory tract’s immune defence system. Researchers have found that people who ate foods rich in flavonoids were less prone to get an upper respiratory tract infection or normal cold than those who did not.


Garlic contains mixtures that naturally act to destroy bacteria and infection, which helps to support your immune system. Consuming garlic may help reduce the risk of becoming sick and staying ill. Outside of keeping your immune system strong, garlic is a great way to spice up a dish. Try adding it to your steamed veggies or roasted chicken to make it savoury.

Always remember that when you eat a healthy food diet, the type of foods you eat will be very important. Eating just one of these foods won’t be sufficient to help fight off the flu or other diseases, even if you eat it constantly. Pay attention to serving sizes and suggested daily intake so you don’t get too much of a single vitamin and too little of others. Eating a well-balanced diet that consists of enough protein, fibre, vitamins, and minerals will help support your body’s immune system.
