Phytochemicals
Considerable differences exist between onion varieties in phytochemical content, particularly for polyphenols, with shallots having the highest level, six times the amount found in Vidalia onions.[38] Yellow onions have the highest total flavonoid content, an amount 11 times higher than in white onions.[38] Red onions have considerable content of anthocyanin pigments, with at least 25 different compounds identified representing 10% of total flavonoid content.[38]Source: Wikipedia https://en.m.wikipedia.org/wiki/Onion
