There are lots of reasons to avoid processed foods. They’re often packed with sugar, fat and salt, and they tend to lack certain nutrients critical to health, like fiber. And now, new research suggests that some of the additives that extend the shelf life and improve the texture of these foods may have unintended side effects — not on our bodies directly, but on the human microbiome, the trillions of bacteria living in our guts.
These substances may selectively feed the more dangerous members of our microbial communities, causing illness and even death.
