Walnuts are not only deliciously crunchy, they offer omega-3 fatty acids, fiber, and antioxidants in every bite. They’re linked to a lower risk of heart disease, better brain health, and slower cancer growth. New research suggests an additional benefit to the body. In an animal study, researchers found that adding walnuts to the diet increased the number of strains of bacteria, including “friendly bacteria” such as Lactobacillus, which helps protect your health. Walnuts may act as a “prebiotic,” a food that helps beneficial bacteria in the gut proliferate. They make a delicious, filling snack on their own or paired with apples or berries. They’re also excellent chopped and sprinkled into oatmeal, or toasted and added to salads.
