Dietary science is shaky on a good day. When you throw in new and/or trendy terms, like microbiota, vegan, and plant-based, it becomes even shakier. Angela Dowden tries to digest (sorry) a new study that looks at weight loss, diabetes, vegan diets and gut microbiota. The results may surprise you.
human microbiome
Probiotics are one of the recent darlings of the supplement world. But do they do anything? A small human study says yes. But what they do isn't good.
When I was still in school, the rule-of-thumb for the human microbiome was that bacteria outnumbered human cells 10-to-1. Not so, say the authors of a new PLoS Biology paper, who re-crunched the numbers. According to their estimate, the ratio is much closer to 1-to-1.
