The three top killers in the United States are no longer heart disease, cancer, and stroke. Stroke just moved down to number four. Number three is now COPD, chronic obstructive pulmonary disease, meaning respiratory disorders such as emphysema. We know we can prevent and even help treat the other top killers with diet (see, for example, Heart Disease: There Is a Cure and my 4-min. video Cancer Reversal Through Diet?), but what about COPD?

Though most COPD is caused by tobacco, up to a third of COPD sufferers never smoked. The title of an editorial in this month’s issue of the American Journal of Clinical Nutrition describes where some of the remainder of risk is coming from: “More Evidence for the Importance of Nutritional Factors in Chronic Obstructive Pulmonary Disease.”

There’s been a burst of new research over the last ten years to answer just that question.

In 2002 we learned that every extra serving of fruit we add to our daily diet may reduce our risk of getting and then eventually dying from COPD. Read more…
