Taken from the Food Matters website…great movie btw!

“Superfoods are a special category of foods found in nature. By definion they are calorie sparse and nutrient dense meaning they pack a lot of punch for their weight as far as goodness goes. They are superior sources of anti-oxidants and essential nutrients – nutrients we need but cannot make ourselves. We all may be adding more salads and vegetables to our diets, but concern over the quality of foods grown on mineral depleted soils makes Superfoods an intelligent choice.”

There is a great list and description of Superfoods on the site including, green, fruit and nut, bee, seaweed and herb Superfoods.
