Fermented rice bran, created by fermenting rice byproduct with beneficial bacteria, shows promise in helping manage weight and blood sugar levels in studies using rats on high-fat diets. The fermentation process increases the nutritional value of rice bran by boosting protein, fiber, and antioxidant content. Animals supplemented with fermented rice bran for 8 weeks showed improved cognitive function, better liver health, and improved lipid profiles compared to those on high-fat diets alone.
