This bedtime snack swap could rewire your gut and help prevent diabetes

A new study reveals that swapping a typical nighttime carbohydrate snack for pistachios may beneficially alter gut bacteria in people with prediabetes. Conducted by Penn State researchers, the 12-week clinical trial found that pistachio consumption increased beneficial gut microbes like Roseburia and reduced harmful ones such as Blautia hydrogenotrophica. These microbiome changes could potentially support metabolic health and slow the progression to Type 2 diabetes. While more research is needed to confirm health outcomes, this study positions pistachios as a promising late-night snack with microbiome-boosting potential.
