In addition to this, elderberry is rich in dietary fiber and contains phenolic acids and anthocyanins, which help reduce the damage caused by oxidative stress.

2. Yogurt – The live cultures found in yogurt are teeming with healthy bacteria called probiotics. Probiotics boost the immune system by decimating bad bacteria in the gastrointestinal tract. The GI tract is where most of your immune system is located. By creating a balanced gut microbiome, you can enhance your immunity and fight off many illnesses and diseases.

4. Garlic – Garlic contains allicin, which helps to improve your immune health. Allicin has been shown to decrease bacteria in the body and fight of infection. The National Institute of Health published findings that determined that garlic decreased inflammation in the ear by increasing the production of natural killer cells.

6. Sweet potatoes – Sweet potatoes are rich in vitamin A. Vitamin A is responsible for keeping your skin healthy. Many people do not realize that the skin plays a major role in immunity. In addition to sweet potatoes, you can increase your vitamin A by eating orange fruits and vegetables, including carrots, squash, pumpkin, and cantaloupe.

7. Bell peppers – Bell peppers are filled with antioxidants like vitamin C . When your body does not get enough vitamin C, your immune resprqueonse can become impaired, which will make you susceptible to infections. Vitamin C helps to reduce the severity and longevity of respiratory infections.

When you do not get enough vitamin D, you have an increased risk of respiratory infections and immune disorders like type 1 diabetes, Crohn’s disease and multiple sclerosis. 

9. Mushrooms – Mushrooms have been shown to increase the activity and production of white blood cells to help you better fight off infections. The best mushrooms to boost your immunity include reishi, shiitake and maitake mushrooms.

10. Fatty fish – Fatty fish are high in omega 3 fatty acids which help to boost your immunity, decrease inflammation and protect your lungs by increasing airflow. Omega 3 fatty acids can help ward off respiratory infections, the flu, and the common cold. 

11. Oysters – Oysters offers some of the best virus-fighting protection. They are loaded with zinc. Zinc creates and activates white blood cells and improves the healing of wounds. In addition to oysters, you can find it in red meats, fortified cereals, and whole grains.
