What Happens To Your Gut Health When You Eat Lots Of Peanut Butter – Health Digest

When it comes to gut health, it’s about balancing the bacteria that’s good for you with the ones that aren’t so good for you, shared nutritionist Sam Gold with Stylist. A healthy body has both of these helpful and harmful gut microbes co-existing side-by-side. 

According to a 2020 study published in the British Journal of Nutrition, eating peanuts, even as little as an ounce a day, increased the concentration of ruminococcaceae, “a group of bacteria linked to healthy liver metabolism and immune function,” per the researchers’ press release (via Stylist). 

Another study, published in 2023 in the Journal of Functional Foods, found a link between peanut butter’s ability to affect gut health, which in turn had a positive impact on a person’s mood. Biologist and study co-author Sara Hurtado-Barroso shared (via PR Newswire) that this may have to do with the prebiotic ingredients in this breakfast staple. “Prebiotic substances present in peanuts and peanut butter, such as polyphenols, may positively affect cognition and mood by promoting production of microbial phenolic metabolites,” she explained. So does this mean you should be loading up on peanut butter every chance you get?
