Here's some juicy news: Oranges, grapefruits, lemons, blueberries, cherries, and blackberries can really keep your juices flowing.

It turns out that a diet rich in those tasty treats, as well as black currants and radishes, delivers a good dose of circulation-boosting phytochemicals called anthocyanins, flavanones, and flavones.

A new study of 50,000 men by the University of East Anglia in the UK and Harvard University, which was published in the “American Journal of Clinical Nutrition,” found that a higher total fruit intake was associated with a 14 percent reduction in the risk of erectile dysfunction.

They also say that consuming a mix of flavonoid-rich foods is as good for maintaining healthy erectile function as briskly walking for up to five hours a week. But add exercise to that phytochemical-rich diet, and you reduce the risk of ED by 21 percent.

The benefits were strongest among guys under 70.

So get out that blender. Berry Orange Smoothies combine 1 cup nonfat or low-fat vanilla soy milk; 1 cup frozen and/or fresh blueberries, blackberries, and/or raspberries; 1 medium ripe banana; 1/2 cup orange juice with one ice cube or 1 tablespoon frozen orange juice concentrate.

Add some green power to the mix with a blend of fresh or frozen berries and citrus; nonfat Greek yogurt; kale; unsweetened almond/soy milk and a little flaxseed. That'll keep the juices flowing.
