Dietary patterns linked to longevity and cancer risk

Recent nutritional studies involving large populations in Canada and the United States have highlighted the significant impact of dietary patterns on longevity and disease risk.

A machine learning analysis of nearly 30,000 Canadians found that dietary patterns rich in vegetables, legumes, and plant-based foods are associated with a 51 percent lower risk of all-cause mortality and a 45 percent lower risk of cardiovascular disease. Conversely, diets dominated by sugar-sweetened beverages, refined grains, and salty snacks were linked to higher mortality risks and shorter life expectancy.

In a separate study published in Gastro Hep Advances, researchers identified a link between sugar-sweetened beverages and stomach cancer. Led by Andrew T. Chan of the Mass General Brigham Cancer Institute, the study found that individuals consuming at least one sugar-sweetened beverage daily had a 2.45 times higher probability of developing stomach cancer compared to non-consumers. This marks the first study to establish this specific connection within the US population, whereas previous research had focused on links to colorectal, breast, and liver cancers.
