The Allium Family: Onions, Garlic, Chives, Leeks, Shallots & Scallions

You might want to carry a breath mint or two, because this family of foods contains a whole host of superfood goodness. Snyder explains, "Like blueberries, onions — and particularly red onions — have been used for centuries in India to improve memory. The key is in a naturally occurring flavonoid, fisetin, which facilitates long-term memory by stimulating certain pathways in the brain."

Perricone adds that this valuable veggie family is a powerful tool to prevent cancer. "Garlic, onions, leeks, and chives contain substances that stimulate the production of glutathione — the liver’s most potent antioxidant. Glutathione enhances elimination of toxins and carcinogens, putting the allium family of vegetables at the top of the list for foods that can help prevent cancer."

Additionally, eating garlic can help lower total cholesterol (and raise the good HDL cholesterol), lower blood pressure, and reduce blood clots. Onions can boast many of these same benefits, but with the added bonus of preventing colds and reducing the risk of diabetes. Leeks are also known to contain vitamins B6, C, folate, magnesium, iron, and fiber.

In short, you’ll look smarter and feel better by adding these great superfoods to your diet. Just, you know, feel free to tell people about the health benefits when you’re popping breath mints and gum post-meals.
