Your mistake: Boiling them
The fix: Steaming
Why it works: Steaming helps retain cancer-fighting nutrients in cruciferous vegetables, such as broccoli, cauliflower, kale, and arugula, better than other cooking methods. Also, when you boil vegetables many of the vitamins found in them are released into the water so, unless you drink the water, steaming in a steaming basket for 3 to 4 minutes is your best bet.
Your mistake: Slicing them before eating
The fix: Eating them whole
Why it works: Whole strawberries contain 8 to 12 percent more vitamin C than the cut strawberries because vitamin C begins to break down when it’s exposed to light and oxygen. For the biggest C boost, store whole strawberries in the fridge—cool temperature help retain vitamin C too.
Your mistake: Letting a bottle “breathe”
The fix: Sipping a freshly opened bottle
Why it works: When red wine is left open for long periods of time—up to 12 hours—the organic acids and polyphenols begin to break down. Leaving the bottle open overnight removes the usual benefits of a glass of red including decreased depression, increased testosterone, and a healthier heart.
Your mistake: Eating them raw
The fix: Heating them up
Why it works: Tomatoes have been linked to lowering the risk of stroke, helping fight prostate cancer, and preserving brain power with age. Heating tomatoes significantly increases their levels of lycopene, the chemical that can up antioxidant levels. Cook tomatoes in olive oil for the biggest nutritional boost: Lycopene is fat-soluble, meaning you need fat in your diet for your body to absorb it properly.
Your mistake: You skip right over frozen foods at the grocery store
The fix: Hitting the freezers
Why it works: Most people think only fresh is healthy, but this is a huge misconception. In fact in most cases frozen fruits and vegetables pack higher levels of antioxidants—including polyphenols, vitamin C, and beta-carotene—than the fresh kind. As produce ages, nutrients begin to change and break down. It's therefore better to eat food that was frozen at prime ripeness with its nutrients intact than week-old produce that no longer has the same beneficial chemical makeup.
