Apples are a super food – and can fight everything from cancer to heart disease. That’s because they’re high in fiber, low in calories and high in nutrients: A trifecta that’s so powertful, eating just one apple a day for a month can lower bad cholesterol by 40%! But there are 7,500 varieties of apples – and some are better for our health than others. So keep these tips in mind:

  • First: The redder the better. The red color in red apples comes from a special heart disease fighting compound. It’s the same one that’s in red wine. And the redder the apple, the bigger the dose of heart healthy chemicals. In fact, Red Delicious apples have the highest concentration of polyphenols of any variety.

  • Another apple secret: Buy organic. Conventionally gown apples grow larger. But all that does is dilute the nutrients with more water. So organic apples may be smaller – and more imperfect looking – but they have a bigger dose of vitamins.

  • Also, be picky. Bruises or soft spots on an apple can be a sign of decay or infection. And as soon as you shop, store your apples in the fridge. A study found that refrigerated apples maintain a higher concentration of healthy nutrients than those left at room temperature.

  • And the final bit of apple wisdom - leave the skins on. The peel has 8 times more polyphenols compared to the actual flesh. Polyphenols do everything from boost your immune system to fight cancer.
