"By following more than 100,000 people in the U.K. for years, researchers found that people whose food choices scored high in any one of five diet categories tended to live longer than people who scored the lowest. Specifically, the team found that even after adjusting for confounding factorssuch as whether people smoked, how much exercise they took and what their education and ethnicity wasstudy participants who tended to eat according to any one of the five diets were 18 to 24 percent less likely to die of any cause. For women, that roughly translated into an extra 1.5 to 2.3 years of life. And for men, it added about 1.9 to three years."
"The five diets that were singled out by the researchers centered on fruits and vegetables, healthy fats and whole grains, with minimal processed foods. Fiber intake, in particular, showed a strong association with longevity, while consuming lots of sugary beverages was linked to higher all-cause mortality."
"Marion Nestle, a nutrition and food studies professor emerita at New York University, says the results are not a surprise but that they add to the evidence for healthy eating. It's always amazing to me that it takes research of this depth, complexity and size to conclude that eating heathy diets is good for health and longevity, she says."
Following more than 100,000 people in the U.K. for years showed that higher adherence to any one of five healthy diet patterns correlated with lower mortality. The five diets emphasized fruits and vegetables, healthy fats and whole grains, with minimal processed foods. After adjusting for smoking, exercise, education and ethnicity, people scoring high on any of the diets were 18 to 24 percent less likely to die of any cause. Estimated life gains ranged about 1.5 to 2.3 years for women and 1.9 to 3 years for men. Higher fiber intake strongly associated with longevity, while heavy sugary beverage consumption linked to increased all-cause mortality.
