In addition to their antioxidant activity, polyphenols have many other health benefits. Some studies strongly suggest that diets rich in polyphenols may offer protection against development of certain cancers, cardiovascular diseases, diabetes, and neurodegenerative diseases.

New Study: Best beverage for blood sugar levels?

Researchers compared red and white wine, and green, black, and white tea for polyphenol content, antioxidant activity, and ability to inhibit sugar absorption in the intestines.

Results: Green tea had the highest polyphenol content, followed by the other teas, then red wine; white wine had very little polyphenol content.

Green tea had the highest antioxidant activity (78% inhibition of free radicals) followed by red wine (59%), then the other teas and finally white wine (10%).

Red wine almost completely inhibited the enzymes that break down carbohydrates; green and black tea also had significant inhibition of these enzymes.

Conclusion: For overall health benefits, including reducing blood sugar, drink red wine or green tea!
