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 ...
Lycopene - found in high concentration in cooked red tomato products like canned tomatoes, tomato sauce, tomato juice and garden cocktails, guava and watermelons. Zeaxanthin - best sources are kale, collard greens, spinach, turnip greens, Swiss chard, mustard and beet greens, corn, and broccoli

Black beans: Half a cup of canned black beans offers 6g each of fiber and protein, as well as various micronutrients such as iron, magnesium, manganese, folate and thiamine.
The main cause of phytochemical loss from cooking is thermal decomposition. [35] A converse exists in the case of carotenoids, such as lycopene present in tomatoes, which may remain stable or increase in content from cooking due to liberation from cellular membranes in the cooked food. [36]
The fiber-rich grain freezes very well, so cook up a batch to stash away for salads, bowls and more. Topped with spinach, peanuts and an egg, these bowls make for a satisfying breakfast. Sprinkle ...
Proanthocyanidins are a class of polyphenols found in many plants, such as cranberry, blueberry, and grape seeds. Chemically, they are oligomeric flavonoids. Many are oligomers of catechin and epicatechin and their gallic acid esters. More complex polyphenols, having the same polymeric building block, form the group of condensed tannins.
In a comparison of cooking methods, phenolic and carotenoid levels in vegetables were retained better by steaming compared to frying. [52] Polyphenols in wine, beer and various nonalcoholic juice beverages can be removed using finings, substances that are usually added at or near the completion of the processing of brewing.
