Every few months, a new “superfood” floods the internet, and the world starts obsessing over it. Kale, avocado, and coconut oil are just a few examples. But what makes a food super? If it’s based on nutritional value, there are plenty of "superfoods" that you may already be eating but that have not been given their share of the hype.

To find out exactly which foods are the best for us, researchers tested 1,000 different raw foods and assigned each a nutritional score. The higher the score, the more effectively that food will help you meet your daily dietary needs.
