Where do research findings indicate the highest concentration of flavonoids resides within the onion bulb?
Answer
The outer layers
A critical point regarding maximizing nutritional intake focuses on the physical location of beneficial compounds. Research specifically points out that the outermost layers of the onion bulb are where the highest concentration of flavonoids, such as quercetin, are located. This knowledge directly influences preparation methods, suggesting that excessive peeling—removing layers beyond the dry, papery skin—can inadvertently discard the most potent parts of the vegetable, thereby reducing the effective dose of antioxidants consumed.
