Forget about the apple – an onion a day may keep cancer away. According to Cornell University food scientists, onions are another super food. Packed with anti-cancer chemicals, onions contain antioxidants that can prevent cancer by blocking free radicals from damaging cell DNA and inhibiting the cancer process from starting.

Before you run out and purchase a bushel of onions, it’s important to note that not all onions are created equal when it comes to fighting the Big C – shallots, red, and yellow onions contain higher anti-cancer chemicals. Research also indicates that cutting onions and allowing them sit for a minimum of 5 minutes before cooking or consuming enhances the onion’s health benefits.

All about Onions


  • Appearance: Shallots have sectional cloves similar to garlic. In fact, they look like large cloves of garlic that have been covered in onion skin. The outer layer is a pinkish brown color; once peeled they resemble red onions.
  • Flavor: Shallots are on the sweeter side and have a mild flavor.
  • When Shopping: Ensure there aren’t any white or green sprouts forming at the top of the shallot. A sprouting shallot is past its prime.
  • Storage: Store shallots in a cool, dry place such as the pantry.
  • Cooking: Shallots can be consumed raw or cooked. If cooking, keep in mind they have a faster cooking time than other onions.

Red Onions

  • Appearance: Deep purple outer layer with white and pink flesh.
  • Flavor: Red onions have a mild to sweet flavor.
  • When Shopping: Look for onions that have a smooth and firm skin. Avoid onions that are soft and have dark spots or areas of mold.
  • Storage: Store in a cool, dry place with plenty of ventilation. Do not store in plastic bags or a refrigerator.
  • Cooking: Red onions can be consumed raw or cooked. If cooking, the red color washes out, but the flavor remains.

Yellow Onions

  • Appearance: Yellow onions have a yellow-brown outer layer with bright white flesh.
  • Flavor: Yellow onions have a strong, pungent smell and flavor. Slightly astringent, they become sweeter the longer they are cooked.
  • When Shopping:  Look for firm, baseball sized onions that have a fairly tough outer skin. Avoid onions that are soft, moist, and have dark blemishes or areas of mold.
  • Storage: Store in a cool, dry place that has good ventilation.
  • Cooking: Yellow onions are usually too strong to be consumed raw, but they work well in sautés, sauces, and on kabobs.
