There are no standard criteria or approved list of super foods. It actually is a term used to describe foods with health benefits and not term used by dietitians and nutrition scientists. Generally Superfoods are nutritionally dense so considered good for health.
Some common foods on superfood lists are blueberries, beans, whole grains, nuts, and salmon. What do these have in common? They have extra-large doses of vitamins and minerals that can help us ward off diseases and live a longer, healthier life. Though a key to a healthy diet is to consume a variety of nutritious foods in the right quantities.
Remember that different colored fruits and vegetables have different vitamins and minerals. Monthly food tip is from Warm Springs Diabetes Program.
