While food addiction is not considered an official diagnosis, some people have a hard time controlling the amount of highly processed foods they consume. In research published in the journal Gut, scientists analyzed the microbiome bacteria of mice and humans with food addictions. They found that the bacteria in mice and humans with food addictions were different from their counterparts with a healthy food relationship. The food-addicted groups had lower levels of the beneficial Blautia bacteria and high levels of the detrimental Proteobacteria in their microbiomes. When the researchers increased the Blautia bacteria levels in the mice that had become compulsive eaters, the compulsive behavior stopped. While a correlation between the microbiome makeup and eating patterns has been identified, more research is needed to understand whether that relationship is a cause or a marker for compulsive eating.
