When there's not enough oxygen, some bacteria have a clever way to keep producing energy. They use different molecules, called electron acceptors, to help them breathe without oxygen. These molecules often come from the food we eat.
Certain foods, like some plant-based compounds (e.g., plant-based polyphenols), have functional groups that bacteria can use directly to help them breathe. The transformation of dietary xenobiotics by microbes influences the [composition of the gut microbiome](brain://dKy6u97_H0O7hamiLSjk7A…
