These nutritional powerhouses from blueberries and kale to seagreens and gogi berries are revered by foodies and anyone who is health conscious. Although dietitians may crinkle their noses at the crown these foods carry since the science behind them is not conclusive, those seeking the fountain of youth or just better health and marketers are heralding this food group.

What elevates a food to the superfood list? They are rich in antioxidants, fiber or fatty acids, packed with vitamins and minerals and believed to help or prevent cancer and other diseases. They are supposed to give you more energy and help keep cholesterol and blood pressure levels in check. They are just “super.”

There is not an Academy Awards ceremony to award the best foods each year, but trends seem to point to the ones shared in the Healthy Aging series called, “The Magnificent 7.”

Blueberries, King of the Hill

Blueberries are at the top of the superfood list with their high antioxidant and vitamin content. They are low in fat, high in vitamin C and low in calorie. One cup has 80 calories.

According to the U.S. Highbush Blueberry Council, the trade association for growers, “blueberries have consistently been recognized as the fruit with the highest antioxidant activity. These tasty berries offer twice as many health-giving antioxidants as spinach, more than three times as many as oranges, red grapes and cherries and more than four times as many as grapefruit, white grapes, bananas and apples.”
