It is challenging to determine the overall amount of dietary polyphenols present in foods as well as to comprehend how these compounds contribute to good health and the prevention of disease due to the diversity of their chemical structures. The total polyphenol content of foods has often been estimated using global redox colorimetric tests. These tests, however, are not very specific. By using chromatography, the contents of certain polyphenols have been identified. The Phenol-Explorer database has gathered these data, which were dispersed throughout several hundred articles. The purpose of this paper is to use this information to identify the top 100 dietary sources of polyphenols.
What are the methods for Identification of the 100 richest dietary sources of polyphenols?
Information on the content of 502 polyphenol glycosides, esters, and aglycones in 452 foods was retrieved using sophisticated searches in the Phenol-Explorer database. The sum of the contents of each individual polyphenol was used to compute the total polyphenol content. These content values were contrasted with the antioxidant content in the same foods as determined by the Folin test technique. The same database's values were also taken out for these values. Using typical serving sizes, amounts per serving were computed.
Which foods have the highest polyphenol content?
The richest sources included several types of spices and dried herbs, cocoa products, some dark-colored berries, flaxseed, chestnut, and hazelnut nuts, as well as some vegetables, like olive and globe artichoke heads. It was determined which 89 foods and drinks contained more than 1 mg of total polyphenols per serving.
