Polyphenols are thought to play diverse roles in the ecology of plants. These functions include: [41] Release and suppression of growth hormones such as auxin. UV screens to protect against ionizing radiation and to provide coloration (plant pigments). [5] Deterrence of herbivores (sensory properties). Prevention of microbial infections ...
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 ...
Molecular structure of the flavone backbone (2-phenyl-1,4-benzopyrone) Isoflavan structure Neoflavonoids structure. Flavonoids (or bioflavonoids; from the Latin word flavus, meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans.
Polyphenols in plant-based foods may trigger gastrointestinal hormones that could help reduce a person's risk for both obesity and type 2 diabetes, new research indicates.
These tasty nuts are rich in polyphenols, good-for-you plant compounds linked to better heart health. Polyphenols are antioxidants that work to neutralize harmful free radicals, reducing oxidative ...
The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. [1] The name derives from the Latin word for "wood". [2] Lignans are precursors to phytoestrogens. [1] [3] They may play a role as antifeedants in the defense of seeds and plants against herbivores. [4]
Recent research has also found that a diet filled with foods rich in flavonols — the bioactive compound found in plant-based foods — is ... polyphenols that protect against oxidative stress ...
As they are present in food consumed in human diets and in plants used in traditional medicine of several cultures, their role in human health and disease is a subject of research. [ 1 ] [ 5 ] [ 6 ] [ 7 ] : 104 Some phenols are germicidal and are used in formulating disinfectants.
