Scientists from the Shibaura Institute of Technology in Japan and the University of Catania in Italy have discovered that bitter and astringent polyphenols found in fruits, berries, vegetables, coffee and tea can improve memory and blood sugar control. results published In the journal Biomolecules.
The scientists’ studies represent a scientific review of existing research on the human health benefits of consuming polyphenols. Polyphenols are powerful plant compounds known for their antioxidant properties. They can protect cells from damage thanks to special forms of oxygen that accumulate in the body over time.
A scientific review found that consumption of bitter polyphenols (castalagin, grandinin, and vescalagin) found in green tea stimulates the synthesis of hormones in the gastrointestinal tract necessary to regulate blood sugar levels.
Astringent polyphenols (flavanols) have also been found to regulate activation of the hypothalamic-pituitary-adrenal axis. This is the main neuroendocrine system responsible for maintaining homeostasis of the body, adapting to environmental factors and surviving under stress. This axis also has profound effects on the regulation of emotions and memory. It is stated that cocoa beans contain abundant astringent polyphenols.
