Anthocyanin extracts are not specifically listed among approved color additives for foods in the United States; however, grape juice, red grape skin and many fruit and vegetable juices, which are approved for use as colorants, are rich in naturally occurring anthocyanins. [46]
Naringenin is a flavanone from the flavonoid group of polyphenols. [2] It is commonly found in citrus fruits, especially as the predominant flavonone in grapefruit. [2]The fate and biological functions of naringenin in vivo are unknown, remaining under preliminary research, as of 2024. [2]
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).
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]
Foods with a high flavonoid content include parsley, onions, blueberries and strawberries, black tea, bananas, and citrus fruits. [11] One study found high flavonoid content in buckwheat. [12] Citrus flavonoids include hesperidin (a glycoside of the flavanone hesperetin), quercitrin, rutin (two glycosides of quercetin, and the flavone tangeritin.
Fruits are also packed with micronutrients, such as folate, vitamins and antioxidants, which can reduce the risk of future diseases including cancer, cardiovascular disease and even depression.
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]
Pectin, which many fruits also contain, does a similar thing to cholesterol, Freeman adds. ... Apples are a major source of fiber, and contain vitamin C and polyphenols, a type of phytochemical ...
