In a study from Vanderbilt University Medical Center, scientists found a diet high in fiber and yogurt is linked to a reduced risk for lung cancer.
The benefits of a diet high in fiber and yogurt have already been found for heart disease and gastrointestinal cancer.
The findings were based on an analysis of data from studies involving 1.4 million adults in the United States, Europe, and Asia.
The study suggests 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 among 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 (non-digestible 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.
