The term superfood is not recognized in medical and scientific communities, it is a term that was created for advertising purposes to aid in selling certain food products that the seller claims are high in nutrients that will solve all of your health concerns.  While the businesses may exaggerate the benefits, there is a certain amount of truth behind the idea of superfoods.
      Common among all or most superfoods touted in the media are certain qualities of nutrient richness and density, meaning they provide a wide array of nutrients and possess them in high enough concentrations that you can eat less of them than other foods and still reap the same nutritional benefits. As such they are also frequently low in calories. Most superfoods discussed in the media are also high in disease-fighting antioxidants or other bioactive components.
Super Food Examples
      Examples of superfoods include blueberries, broccoli, spinach, pumpkin and tomatoes which are rich in various nutrients. All these fruits and vegetables contain a variety of nutrients and phytochemicals in varying amounts as do common plant foods like bananas, pineapples and potatoes which have only rarely been called superfoods. Fish may be considered a superfood due to their omega-3 fatty acids which may promote cognitive development.
      Other examples of superfoods are: wheat grass, barley, chia seeds, pomegranates and juice, and bee pollen.
Health Concerns
       While many “superfoods” are commonly recognized foods whose health benefits have been long recognized, others still need to undergo scientific testing to ensure that the benefits are there, and that there aren’t any negative side effects.  For example, some seaweeds hailed as superfoods contain natural toxins which are thought by some to increase risk of cancer and liver damage.
       The moral of this story is that some of these superfoods do have some scientific evidence supporting their health benefits, and others are yet to be proven.  If you are looking for a more effective way to improve an aspect of your health, you should look into changing your diet, and definitely consider including the superfoods.  But when you consider adding superfoods to your diet to help reach your goal you should do a little research first.  Make sure you are getting what you pay for.
