Importance of polyphenols in our daily diet

Importance of polyphenols in our daily diet
Polyphenols are very widespread and the most ubiquitous metabolites known in nature. Although they exist in plenty, most of these compounds are from a common origin i.e. the amino acids like phenylalanine or tyrosine. Based on their chemical structures they are majorly classified into simple phenols, benzoic and cinnamic acid, coumarins, tannins, lignins, lignans and flavonoids. Among these, flavonoids are the most commonly known polyphenols in nature. In polyphenols, dietary polyphenols play a major role owing to their contribution in human health. Polyphenols are richly found in fruits, vegetables, whole grains and other types of foods and beverages, such as tea, chocolates and wine. Polyphenols majorly function as strong anti-oxidants that are complementary to the anti-oxidant vitamins and enzymes present in the body, which help in fighting against oxidative stress caused by excess reactive oxygen species (ROS). They also contribute in the production of potent anticancer agents, cardio protectants and inhibitors of neurodegeneration. They also possess anti-inflammatory, oestrogenic, enzyme inhibition, antimicrobial, antiallergic, vascular and cytotoxic anti-tumour activities. We should try consuming good level of phenols from the above mentioned foods to maintain good health.
