Onions in general are good for us, but red onions have a higher concentration of flavonoids in the outer layers, which, according to a Cornell study, can help reduce the risk of cancer, heart disease, and diabetes. Red onions also contain the brain-boosting flavonol quercetin, which helps keep memory in tip-top shape.
Here are some interesting and useful tips when cooking with red onions.
- Don't over peel your onion: Since a majority of the flavonoids in red onions are in the fleshy, outer layers, try to retain as much of the outer layer as you can.
- Onion expertise: When shopping for red onions, opt for ones that have dry outer skins, appear clean, and have a nice round shape. You also want to avoid any that have soft spots, dark patches, are showing signs of mold, or are sprouting, as these are all signs of decay.
- How to store red onions: Make sure you keep your onions away from heat and bright lights, and keep them stored in a well-ventilated area.
