Global burden of non-communicable diseases attributable to dietary risks in 1990-2019.

Background: Dietary risks have raised attention worldwide during recent decades. The present burden-of-disease study aimed to evaluate the global dietary risks for non-communicable diseases (NCDs) from 1990 to 2019 and quantify their impact on mortality and disability-adjusted life-years (DALYs). Data from the 2019 Global Burden of Disease Study on deaths and DALYs from NCDs attributable to worldwide dietary risks were obtained and underwent deep analysis by year, age, gender, location, leading risks and leading causes, and their associations were examined.

Photo-catalytic polymerization of catechin molecules in alkaline aqueous.

Polyphenols are associated with a wide range of physiological properties. Catechin is a flavan-3-ol with five phenolic hydroxyl groups. After blue light illumination, the transparent solution of catechin became yellowish.
