Phytonutrients deserve the lime-light. There are six types of hard-to-pronounce phytonutrients: flavonoids, carotenoids, polyphenols, phytosterols, phytoestrogens and glucosinolates.
Natural phenols are a class of molecules found in abundance in plants. Many common foods contain rich sources of polyphenols which have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion. [7]
The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods.For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content [5]) and vegetables such as broccoli ...
Others, such as some polyphenols and flavonoids, may be pro-oxidants in high ingested amounts. [23] Non-digestible dietary fibers from plant foods, often considered as a phytochemical, [24] are now generally regarded as a nutrient group having approved health claims for reducing the risk of some types of cancer [25] and coronary heart disease. [26]
Research links eating pomegranate arils (seeds) and drinking pomegranate juice with reductions in obesity, diabetes, cardiovascular diseases and even some cancer types.
Solanum nigrum, [46] Tasmannia pepper leaf, anise myrtle and lemon myrtle share a high concentration of polyphenols and polysaccharides, which take a role in inhibition of iNOS and COX-2 activities, resulting "a viable approach to inhibit inflammation and carcinogenesis and to prevent cancer." [50]
Strawberries. Burdeos likes these berries because they contain a high amount of nutrients like vitamin C, potassium, and antioxidants—for only 12 grams of carbs per one-cup serving.
Many other foods and beverages may also contain proanthocyanidins, but few attain the levels found in red grape seeds and skins, [6] with a notable exception being aronia, which has the highest recorded level of proanthocyanidins among fruits assessed to date (664 milligrams per 100 g).
