Vitamin D and COVID-19

The advancements in the biological sciences over the past half a century have been phenomenal. The development of new and sophisticated techniques in genetics and biochemistry has lead to a greater understanding of how our bodies function and the roles genes play at the cellular level. Such information, which is still far from complete, has had a significant impact in improving the health of people around the world. This is evident by the remarkable development of new drugs and vaccines to prevent and treat many diseases including the current pandemic. Nutrition, a relatively young science, has also seen incredible developments, particularly in the area of nutrigenomics. The latter involves studying the effects that foods, specifically individual nutrients, have on gene expression and human health.
