Many of these contain natural phenol to maintain healthy lifestyle. Polyphenols are micronutrients that occur in plants. There are thousands of various polyphenols, and although they are in plenty of supplements, they are also easy to get from fruits, vegetables, teas, and even spices.


Experts recommend an intake of two to three cups of vegetables daily. Those that have the highest polyphenol content are artichoke, red onion, and spinach.
