Top 25 Highest Polyphenol Rich Foods
Often times foods are talked about in regards to their antioxidant content.
Eat this as it is full of antioxidants
Antioxidants, as a class, are very hyped in the media/health arena but the term antioxidant seems to be rather vague and nondescript as there are many different types of antixodants found in different foods, in different amounts, with different functions.
The confusion is compounded by the fact that we as scientist don’t really know the best way to measure the power of antioxidants in foods. There are all kinds of measures – Oxygen Radical Absorbance Capacity (ORAC), Total Antioxidant Capacity (TAC), Trolox Equivalent Antioxidant Capacity (TEAC), etc.
It is just confusing.
But, thanks to a group of French scientists, things are now a little less confusing. These researchers got together in an effort to organize a large portion of this information by compiling a polyphenol database. Polyphenols are a very large class of antioxidants. You may be familiar with antioxidant buzz words like quercetin, lignins, flavonoids, and/or resveratrol. Theses are all example of subclasses or specific examples of polyphenols.
After compiling a polyphenol database containing 452 foods and 502 different types of polyphenols, the researchers ranked foods based on total amount of polyphenols per serving and published this information in the Journal of the American College of Nutrition. The fact that the researchers took the time to make the list on a per serving basis is important from a practical stand point. Often times scientists talk in terms the amount of polyphenols per 100 grams. While this is informative scientifically, when was the last time you ate 100 grams (~17 Tablespoons) of ground cloves (cloves have the highest polyphenol content per 100 grams followed closely by dried peppermint).
