Chocolate is a 'Super Fruit' – Hershey Study

When researchers at the Hershey Center for Health & Nutrition compared the antioxidant activity in cocoa powder and fruit powders they found that, gram per gram, there was more antioxidant capacity, and a greater total flavanol content, in the cocoa powder.

2/7/2011 --- It is widely known that fruit contains antioxidants which may be beneficial to health. New research published in the open access journal Chemistry Central Journal demonstrates that chocolate is a rich source of antioxidants and contains more polyphenols and flavanols than fruit juice.

When researchers at the Hershey Center for Health & Nutrition compared the antioxidant activity in cocoa powder and fruit powders they found that, gram per gram, there was more antioxidant capacity, and a greater total flavanol content, in the cocoa powder.

Similarly when they compared the amount of antioxidants, per serving, of dark chocolate, cocoa, hot chocolate mix and fruit juices they found that both dark chocolate and cocoa had a greater antioxidant capacity and a greater total flavanol, and polyphenol, content than the fruit juices. However hot chocolate, due to processing (alkalization) of the chocolate, contained little of any.

Analysis of the fruit powders demonstrated that the antioxidant capacity of cocoa powder (634 ± 33 μMTE/g) was significantly greater than blueberry, cranberry, and pomegranate powder on a per gram basis. The total polyphenol content of cocoa powder (48.2 ± 2.1 mg/g) appeared to be greater than acai, blueberry, and cranberry powder; however these differences did not reach statistical significance. The total flavanol content of cocoa powder (30.1 ± 2.8 mg/g) was significantly greater than all of the other fruit powders tested. There were no other statistically significant differences in antioxidant capacity, total polyphenol, or total flavanol content between any of the other fruit powders tested.

Dr Debra Miller, the senior author of the paper, says that, "Cacao seeds are a "Super Fruit" providing nutritive value beyond that of their macronutrient composition". Which is great news for chocolate lovers.

This work was funded by The Hershey Company (Hershey, PA).
