Oats (Avena sativa) are a widely cultivated cereal which provide a good source of fibre, vitamins, minerals, antioxidants and beta-glucan. They have been linked to a number of health benefits, including reduced risk of heart disease, lower blood sugar and cholesterol levels. Some of these health benefits are thought to arise through their impact on the gut microbiome. Studies have shown that oatmeal porridge may have prebiotic properties, and aid in maintaining a healthy gut flora.
