In a new study, researchers found a diet high in fiber and yogurt is linked to a reduced risk for lung cancer.
The research was conducted by a team at Vanderbilt University Medical Center
The benefits of a diet high in fiber and yogurt have already been found for heart disease and gastrointestinal cancer.
The new findings based on an analysis of data from studies involving 1.4 million adults in the United States, Europe, and Asia suggest this diet may also protect against lung cancer.
Participants were divided into five groups, according to the amount of fiber and yogurt they consumed.
The team found those with the highest yogurt and fiber consumption had a 33% reduced lung cancer risk as compared to the group who did not consume yogurt and consumed the least amount of fiber.
This strong link is consistently seen across current, past and never smokers, as well as men, women, and individuals with different backgrounds.
The study provides strong evidence supporting the U.S. 2015-2020 Dietary Guideline recommending a high fiber and yogurt diet
The team says the health benefits may be rooted in their prebiotic (nondigestible food that promotes the growth of beneficial microorganisms in the intestines) and probiotic properties.
The properties may independently or synergistically modulate gut microbiota in a beneficial way.
One author of the study is Xiao-Ou Shu, MD, Ph.D., MPH, Ingram Professor of Cancer Research.
The study is published in JAMA Oncology.
