7 Best Foods to Boost Your Immune System

Your immune system is remarkably important. Therefore, having a healthy and strong one is best. A strong immune system reduces your risk of getting infections, helps wounds heal quicker, reduces how tired you feel, and even promotes healthy skin, nails, and hair. Thus, maintaining your immune system is vital. A few ways to build and maintain your immune system are to eat plenty of fruits and vegetables, be physically active, maintain a healthy weight, get quality sleep, and avoid drugs and alcohol.

However, in addition to these things, there are specific foods that you can include in your diet that will give your immune system a boost. Foods like citrus fruits, oily fish, almonds, blueberries, and broccoli can give your immune system a healthy, revitalized boost. Today, those are the details we’re sharing! Learn about seven foods that will amp up your immune system!

1. Citrus Fruit

Citrus fruit is fantastic for boosting your immune system. This is because citrus fruit is packed with vitamin C, which is helpful to the immune system in many ways. First, vitamin C helps with the production of white blood cells, which are needed to fight infections. Second, because the body doesn’t produce or store vitamin C, it’s crucial that we get it daily from other means. Citrus fruits contain soluble fiber, which supports cardiovascular health, and contain antioxidant properties like flaxonoids, carotenoids, and phenolic acid, which protect cells from damage caused by free radicals. Citrus fruit supports good gut health and boosts iron absorption from plant-based iron foods. A few citrus fruits that are amazing for boosting your immune system are oranges, grapefruits, lemons, limes, mandarins, and clementines. 

How to enjoy citrus fruit:

• Make a colourful citrus fruit salad.
• Make a citrus salsa.
• Enjoy a citrus smoothie.

2. Broccoli

Broccoli may be a cringe-worthy vegetable, but believe it or not, it’s phenomenal for your immune system! Broccoli is a nutrient-dense food, rich in vitamin C, high in antioxidants, and high in vitamin E. (Vitamin E is beneficial to the immune system, as it plays a vital role in regulating immune responses.) Broccoli also contains vitamin A, which is crucial for the health and integrity of the skin, and mucosal barriers, which are the body’s first line of defense. Furthermore, broccoli is rich in fiber, which supports a healthy gut and is pivotal for optimal immune system functioning, and a good source of zinc, which enhances immune cell function, enzyme function, inflammation regulation, and wound healing.

How to enjoy broccoli:

• Season and drizzle with your favorite oil, and toss in the oven for satisfying roasted broccoli.
• Make broccoli pesto.
• Indulge in broccoli and cheese soup.

3. Almonds

Almonds are tasty, soft, and crunchy, and they are a great boost to your immune system. They contain vitamin E, which, as you know now, helps protect cells from damage caused by free radicals, monounsaturated and polyunsaturated fats, which are good for heart health, maintain the cell membrane, facilitate the absorption of fat-soluble vitamins, and serve as a good source of plant-based protein, which is vital for building and repairing tissues. Almonds contain zinc, which is involved in the development and function of immune cells, and prebiotic fiber, which supports the growth of healthy bacteria in the gut. 

How to enjoy almonds:

• Eat them raw.
• Make almond granola.
• Make almond-crusted vegetables.

4. Papaya

Did you know that papaya has even more vitamin C than oranges? Papaya is an unbelievably great food if you’re looking to boost your immune system. It’s packed with digestive enzymes, beta-carotene, flavonoids, and phytochemicals. In addition, papaya is a good source of fiber and terrific for hydration, which is necessary for a healthy immune system. Finally, papaya contains compounds that are helpful with wound healing.

How to enjoy papaya:

• Make a papaya smoothie.
• Make a papaya boat with yogurt, seeds, and fresh fruit.
• Make papaya sorbet.

5. Blueberries

I’m sure you’ve heard that blueberries are brain food, but they’re also incredible for your immune system. The tiny, juicy blue fruit is packed with powerful anti-inflammatory properties and supports healthy gut health. Blueberries are also high in vitamin C and work to reduce chronic inflammation in the body. Nutrients in blueberries help to improve blood flow and vascular function, both of which are necessary for the optimal functioning of the immune system. Finally, blueberries contain vitamin K, which enhances immune cell function, improves wound healing, regulates immune responses, and maintains barrier function.

How to enjoy blueberries:

• Enjoy a blueberry smoothie.
• Make blueberry yogurt bark.
• Make blueberry-infused water.

6. Red bell pepper

Red bell pepper actually has more vitamin C than citrus fruit, which is crucial when wanting to give your immune system a boost. It’s also high in dietary fiber, which is good for digestive health, and beta-carotene. Red bell pepper is packed with hydration, which is necessary for good immune function, and is filled with antioxidant properties.

How to enjoy red bell pepper:

• Make a crisp red bell pepper salad.
• Enjoy a red bell pepper stir-fry.
• Make red bell pepper hummus.

7. Oily Fish

Oily fish is an immune system-boosting food that you can easily add to your diet. This is because it contains omega-3 fatty acids, which support immune health. In addition, oily fish typically contain vitamin D, which modulates the activity of immune cells and greatly reduces the risk of autoimmune diseases. Oily fish is a high-quality protein that contains antioxidant properties and supports gut health.

How to enjoy oily fish:

• Make a fish curry.
• Make fish tacos.
• Enjoy a fish sandwich.
