blueberries, eating fruit

As people age, lung function tends to drop. A new study suggests, however, that eating fruit rich in flavonoids may help keep lungs working well (ATS 2018 International Conference, San Diego CA May 21, 2018).

What Are the Benefits of Eating Fruit for Lung Function?

Anthocyanins, found in blueberries, red grapes, cranberries and some other fruit apparently concentrate in lung tissue and reduce inflammation. The scientists were curious whether diet has any impact on lung function, so they analyzed data from more than 400 middle-aged Europeans who participated in Community Respiratory Health Surveys between 2002 and 2012. In addition to completing a dietary questionnaire, the volunteers did spirometry at the beginning and end of the study to measure their lung function.

Those with the most anthocyanins in their diets maintained their lung capacity better than those who had the fewest. The association held up well for people who had never smoked and those who had quit, but disappeared among current smokers. Presumably, the negative effect of smoking overwhelms any benefit from eating fruit full of anthocyanins.

Which Fruits Have Anthocyanins?

Berries such as blueberries, blackberries, cranberries and raspberries, both red and black, are rich in anthocyanins. So are black currants and cherries. Concord and muscadine grapes are also good sources. Eggplant peel and red cabbage, while not fruit, also contain anthocyanins.

    It never ceases to amaze me that “recent studies” are finally catching up with what Mother Nature has to offer. I don’t believe this is a new idea to those who believe in Nutrition. In the 1980’s, my father was diagnosed with advanced COPD/Emphysema. Medicine was not as advanced then for COPD but nutrition always has been.

    My father’s home health nurse encouraged him to follow a program to include fruits and vegetables with an emphasis on Vitamin C and bioflavonoids as well as low sugar and low sodium. I might add this was not prescribed but his choice as well as he followed his medically prescribed program to include breathing exercises and PT to increase lung function.

    While my father eventually passed, he lived much longer than the doctors thought he would. It is this daughter’s opinion that his nutrition played an important role. I have gone on to include Bioflavonoids in mine and my family’s daily nutrition.

    This is especially important as my son and I went on to both be diagnosed with Common Variable Immune Deficiency (CVID). CVID predisposes one to repeated Upper Respiratory Infections. There are times when modern medicines are necessary, but proper nutrition is of utmost importance. Thank You for allowing me to comment. To your health!!

      Thank you, Helen for your experience! My mother is 96 and beginning to show diminished lung function. I will see if her dr could order PT, but could you share information about the breathing exercises? Thank you and best wishes.

        Kathy, if Helen replies will you please share them? I am 86 and still very active, I walk and play golf but had to give up ice skating when my balance became questionable. . .
