In a recent study from Vanderbilt University, scientists found a diet high in fiber and yogurt is linked to a reduced risk of lung cancer.
The benefits of a diet high in fiber and yogurt have already been established for cardiovascular 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, suggesting this diet may also protect against lung cancer.
In the study, researchers divided participants into five groups, according to the amount of fiber and yogurt they consumed.
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.
The study provides strong evidence supporting the US 2015-2020 Dietary Guideline recommending a high fiber and yogurt diet.
This inverse association was robust, consistently seen across current, past, and never smokers, as well as men, women, and individuals with different backgrounds.
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.
