Hamburger lovers, rejoice! Beef is a natural source of vitamin D, as well as other immune-supporting nutrients like zinc. In fact, lower levels of zinc were associated with greater inflammation and poorer outcomes in hospitalised COVID-19 patients, compared with more healthful levels, according to a recent study. Enjoying lean beef in moderation can be a part of a healthy diet, especially in the colder months when sun exposure is limited, and thus our ability to make our own vitamin D is hindered.
