Following a Western Style Diet May Lead to Greater Risk of Premature Death

Data from a new study of British adults suggest that adherence to a “Western-style” diet (fried and sweet food, processed and red meat, refined grains, and high-fat dairy products) reduces a person’s likelihood of achieving older ages in good health and with higher functionality. Study results appear in the May issue of The American Journal of Medicine.

“The impact of diet on specific age-related diseases has been studied extensively, but few investigations have adopted a more holistic approach to determine the association of diet with overall health at older ages,” says lead investigator Tasnime Akbaraly, PhD, Inserm, Montpellier, France. “We examined whether diet, assessed in midlife, using dietary patterns and adherence to the Alternative Healthy Eating Index (AHEI), is associated with aging phenotypes, identified after a mean 16-year follow-up.”

The AHEI is a validated index of diet quality, originally designed to provide dietary guidelines with the specific intention to combat major chronic conditions such as cardiovascular diseases and diabetes.

Investigators analyzed findings from the British Whitehall II cohort study, which suggest that following the AHEI can double the odds of reversing metabolic syndrome, a condition known to be a strong predictor of heart disease and mortality. The research team sought to identify dietary factors that can not only prevent premature death, but also promote ideal aging.
