During these uncertain and stressful times it's important to fuel your body with immune-fighting nutrients to keep your immune system strong. Below are some key nutrients to include in your diet that can prevent you from becoming ill.

Vitamin C and Beta Carotene

Vitamin C and Beta Carotene help fight against infection. Food sources high in Vitamin C and Beta Carotene are citrus fruits, berries, melon, tomatoes and broccoli. Try adding a cup of strawberries to you breakfast in the morning or broccoli as a side dish for dinner.


Zinc can help stimulate your immune system. Food sources high in Zinc include beef, lamb, turkey, and seafood, such as oysters and crab meat. Vegetarians can obtain Zinc from pumpkin seeds, cashews, whole grains, and tofu. An easy way to add more Zinc into your diet is to pack nuts for a mid-afternoon snack or enjoy some oysters for a refreshing summer appetizer.

Vitamin D

Vitamin D is also an important nutrient in immune health. If you are deficient in this vitamin you increase your risk for an infection. Food sources high in Vitamin D include trout, tuna, salmon, or fortified eggs, juices, and milk. Another way to make sure you are getting enough Vitamin D is to go outside for a walk or exercise, as sunlight provides energy for Vitamin D synthesis.

While there is currently no concrete scientific evidence to recommend any supplements to prevent against or treat COVID-19, you can speak to your health care provider for advice on how to improve your diet and nutrition. Some nutritional supplements may interfere with other medications you are taking, so it's always best to speak to your provider before making any changes.
