Food, super: Foods with alleged healing or health-promoting capabilities. The healing power of foods is a popular concept. Medicinal or nutritionally high- powered foods have been part and parcel of the natural products industry for a long time and, through emerging scientific research and particularly through growing public interest, they have reached the mainstream. Not all items advertised as "super" foods or healing foods have been proven to promote health, however, and some may be contraindicated for people with certain health conditions. Before making drastic changes to your diet, always consult with your physician or a professional nutritionist.
