Vitamin D Is Key to a Healthy Immune System, and These 7 Foods Have It in Spades
Trying to stay healthy during cold and flu season has perhaps never been more important than during the COVID-19 pandemic. From frantically washing hands to continuing to have Zoom happy hours, everyone's doing what they can to keep the "bugs" away.
One vitamin that has become a shining star in the wellness world is vitamin D. While this nutrient may be best known for its role in building strong bones, it also supports many functions in the body, including the immune system. Some researchers have gone so far as to suggest that those who have lower levels of circulating vitamin D in their body have an increased risk of developing COVID-19. In fact, the relative risk of testing positive for COVID-19 appears to be nearly two times greater for those who are vitamin D deficient, compared with people with normal vitamin D levels.
Even so, vitamin D also plays an important role in more generally supporting a healthy immune system. It's no wonder then that people are making efforts to get their daily dose of the sunshine vitamin. While there are many ways to help your body meet its vitamin D needs — including direct sun exposure and supplements — there are some foods that naturally contain this important nutrient and can be simple additions to an overall healthy diet. Here are seven to add to your grocery list.
