Can these foods help you breathe better?

The positive health effects of fruits and vegetables like blueberries and purple potatoes to help ward off heart disease and cancer have been known for some time. But now, a new study links these antioxidant– and flavonoid-rich foods to another benefit: protecting your lungs.

Researchers have found that study subjects who ate the most foods containing a flavonoid, called anthocyanins – found in dark-skinned fruits and vegetables, such as red and purple grapes, eggplant, black raspberries and more – held on to the best lung function as they aged.

The study followed 463 adults from Norway and England over a period of 10 years. Researchers observed an association between lung health and anthocyanin consumption, noting that those who had a large quantity of dark-colored fruits and vegetables in their diet had better lung health than the subjects who did not.

The effect was present only among those subjects who had never smoked or who had ceased smoking. Current smokers showed no benefit from the anthocyanins.

Jodi Upchurch, a registered dietitian at Advocate Eureka Hospital in Eureka, Ill., believes fruits and vegetables are a mainstay of a healthy diet. “Fruits and vegetables are rich in nutrients and low in calories, which makes them a great nutritional benefit,” she says. “A wide variety of each is suggested each day to reach the recommended 5-9 servings.”

For a delicious way to get some anthocyanin-rich fruits into your diet, Upchurch recommends her favorite fruit salad recipe:


  • 1 pint blackberries
  • 1 pint blueberries
  • 1 cup fresh cherries, pitted
  • 16 ounces strawberries, sliced
  • 2 tablespoons fresh mint, chopped
  • ½ lime, juiced
  • 1 tablespoon honey


  1. Add the fruit and mint to a large bowl.
  2. In a small bowl combine the lime and honey.
  3. Add the lime and honey mixture to the fruit and gently toss to combine.
  4. Serve immediately or refrigerate until ready to serve.
