Great article! I could add that superfoods are something that containts a high nutritional value in very small quantities. For instance, only 1 gram of the algae AFA will provide about 80% of all the nutrients a person needs for one day. Besides the algae AFA, other types of algae like Spirulinaa can also be added to the list. I will also mention colostrum, honey and wild berries as other examples.
