National Geographic just published an article regarding the study of how our microbiome may help fight viruses, even Covid-19, National_Geographic. “Some preliminary studies have shown unusual microbiomes in hospitalized Covid-19 patients”.
The article mentions that there are 3 possible mechanisms where the microbiome may help combat a virus:
1) The lining of one’s stomach and intestines prevents viruses from getting to organs other than the stomach and lungs. In other words, “leaky gut” may allow access to other organs. The virus has been detected in “the liver, kidney, heart, and brain”.
2) The microbiome could also produce chemicals that interfere with the viral life cycle.
3) The microbiome supports one’s immune system.
The article goes on to discuss some ideas on possible treatments based on these theories, but emphasizes that there has not been enough studies prove the impact of the microbiome on viruses.
The only advice, for now, is to support your microbiome through diet (and even exercise) to give yourself the best possible chances for good health. Look out for more developments in this area over the next few years.
