Research is ongoing, but studies have pointed to “gut health” as impacting not only the digestive system, but the immune system as well. A 2016 study published in the International Journal of Food Sciences and Nutrition found that consuming different strains of probiotics over an eight-week period could reduce body weight and BMI, which are two caution areas related to diabetes, heart disease, and some cancers. Studies at Johns Hopkins have revealed an altering of blood pressure when different gut bacteria are produced in mice, rats, and people. Good gut bacteria have also been known to help reduce allergy symptoms, inflammation, and skin issues, like acne. Experts have been looking at the effects of probiotics on mood and stress, too.
