Consuming five servings of fruits and vegetables each day may help lower lung cancer risk, especially if you eat a variety of fruits and vegetables, suggests a new study.
The World Health Organization estimates lung cancer causes 1.3 million deaths worldwide each year. Globally, cancer-related deaths total 7.4 million per year.
Published in the journal Cancer Epidemiology, Biomarkers & Prevention, researchers found individuals eating a mix of fruits and vegetables were 23% less likely to develop lung cancer. And the more variety of fruits and vegetables consumed, cancer risk drops an additional 4% with each serving.
The scientists state a significant link between fruit and vegetable consumption and lung cancer was only found among smokers, with every two additional servings of fruits and vegetables smokers reduced lung cancer risk by another 3%.
The study, part of The European Prospective Investigation into Cancer and Nutrition (EPIC), involved people from numerous countries, such as Germany, France, Spain, Italy, Norway, the United Kingdom, and Greece.
Despite the benefits of consuming fruits and vegetables, smoking remains the major cause of lung cancer worldwide. In the United States, smoking accounted for 87% of lung cancer cases; 90% for men and 85% for women.
