New study suggests exposure to sunlight could alter gut microbiome in humans

The video discusses a study on the human microbiome, highlighting research by Canadian scientists on the effects of UV exposure on gut flora. The study involved 21 women, revealing that UV exposure increased vitamin D levels and gut microbiome diversity in those not taking supplements. It suggests a potential skin-gut axis and links between sunlight, vitamin D, and diseases like multiple sclerosis and inflammatory bowel diseases, though the causal mechanism remains unidentified.
