This is a question that has been posed to me many times over the past month. I have been providing athletes with two reputable resources that can help navigate these unusual times. First, the Academy of Nutrition and Dietetics, https://www.eatright.org/, has a Nutrition Resource Center that provides a wealth of information related to immune system health, grocery shopping during quarantine, tips for ordering take out and more.
The second resource is the American College of Sports Medicine, https://www.acsm.org/. ACSM has provided numerous tips on staying physically active during the COVID-19 pandemic via handouts, podcasts and blogs. You should be able to find answers to your most pressing questions from the information on these sites.
Stay healthy and well!
