The idea that our gut bacteria change with the seasons isn't just a hunch; it's gaining serious traction in the scientific community. Global research shows a surge of interest in how the gut microbiome varies throughout the year. In fact, a bibliometric analysis of studies published between 1990 and 2022 revealed a massive spike in research, with
65.31% of all publications on the topic appearing in the last three years alone. This boom, driven by better sequencing technology, confirms that our gut ecosystems are dynamic, with microbial diversity and composition changing from one season to the next. You can dig deeper into these
findings on gut microbiome seasonality yourself.
