“Feed a fever, starve a cold,” or is it “Starve a fever, feed a cold?” I can never remember how this old saying goes.

One thing I am certain about though is that starving is never the answer. In fact, your immune system will likely function much better when you eat, especially when following a well-balanced diet.

As coronavirus cases continue to surge, many of us would do just about anything to avoid getting it. We are reminded regularly that wearing a mask, social distancing, good handwashing and staying safe at home is key to avoid getting sick until enough of our population is vaccinated.

But your diet just might play a role in keeping your immune system stronger or reducing the risk of serious complications of an illness.

It is important to mention that while many foods and products on the store shelves claim immune-boosting properties, there is no magic bullet or special dietary supplement that will protect you from COVID-19, colds or the flu.

However, eating a nutrient rich, healthy and balanced diet every day, over time, may indeed offer great protection against some illnesses or get you feeling better faster if you do get sick.

And while there is not one superfood, there are certain nutrients that may play a role in boosting the body’s immune function and can easily be included in your long-term healthy eating plan.

Vitamin C immediately comes to my mind when I think about immune function. As an antioxidant, Vitamin C can help protect cells from damage and plays a role in supporting the skins barrier against pathogens. Fruits and vegetables contain Vitamin C, specifically citrus fruits, peppers, broccoli, berries and tomatoes.

Milk really does do a body good in regards to Vitamin D. This vitamin, found in dairy products, fatty fish, fortified cereals and of course sunlight, has gained even more attention lately in regards to COVID-19.

Studies have shown people with Vitamin D deficiency are more likely to get COVID and experience more severe symptoms of the disease. Vitamin D supplementation may be recommended if you don’t get enough through your diet. Speak to your healthcare provider for more guidance.

Protein plays many roles in our body’s immune function by helping with the development of white blood cells, antibodies and other disease fighting compounds. Protein is essential for disease recovery as well. Meet your daily protein needs with a variety of lean cuts of meat and poultry, fish, low-fat dairy, dried beans, nuts and soy-based foods.

Zinc is necessary for our body’s immune system to work properly and might even help reduce the severity of illnesses such as COVID-19. Zinc can be found in oysters, crab, meat, dried beans, seeds, fortified cereals and oatmeal.

The roles these nutrients play in immunity are an example of just how vital good nutrition is to our bodies. But these nutrients cannot work alone. Place your focus on an overall healthy diet that includes fruits, vegetables, whole grain foods, low-fat dairy products and lean meats, poultry and fish. Also, don’t forget to drink plenty of water and stay hydrated, especially when you are ill.

Finally, remember the importance of regular exercise, adequate sleep and stress management to keep your immune system strong.

The latest Dietary Guidelines for Americans have just been released and will provide scientific guidance for all Americans to “make every bite count.” Visit www.dietaryguidelines.gov for more information.

If you have other questions or concerns about your diet, reach out to your healthcare provider about a consult with a registered dietitian.
