The well-being of your gut microbes depends on the food you eat, and they are more or less programmed in their food preferences during the first few years in life. However, regardless of their original programming, they can digest virtually everything you feed them, regardless of whether you’re an omnivore or a pescatarian. No matter what you feed them, they will use their enormous amount of information stored in their millions of genes to transform partially digested food into hundreds of thousands of metabolites.
