What are polyphenols and flavonoids?
Polyphenols include flavonoids (or “catechins”) and appear to be powerful antioxidants. Certain flavonoids, including quercetin, are more active than others. Laboratory studies have shown that flavonoids suppress tumor growth, interfere with sexual hormones, may help prevent blood clots, and have anti-inflammatory properties. Flavonoids are found in celery, cranberries, onions, kale, broccoli, apples, cherries, berries, tea, red wine, parsley, soybeans, tomatoes, eggplant and thyme. Most common berries, which contain flavonoids, are particularly rich in potent antioxidants. What are isothiocyanates? Isothiocyanates and the related substances, indoles, are often referred to as mustard oils, and are responsible for the sharp taste in cruciferous vegetables (broccoli, cabbage, Brussels sprouts, cauliflower, collards, kale, kohlrabi, mustard greens, rutabaga, turnips, bok choy).
