The Diversity of Healthy Gut Microbiomes

There is no such thing as one single "healthy" gut microbiome. What's healthy for you isn't necessarily

healthy for someone else. Your unique mix of gut bacteria is constantly changing

based on your age, where you live, and your lifestyle. The gut bugs of a baby look completely

different from an adult's, and your microbiome can even change if you move to a

new country. Scientists now realize that trying to find one "perfect" microbiome is the wrong approach.

Instead, they're studying huge populations over many years to map out the entire

spectrum of what "healthy" can look like.
