Want to live longer, avoid greasy, high-fat Western-style diet! Western-style diet high in fat and sugar leads to earlier cognitive and physical decline,a long-term study of 5,350 British men and women has claimed. Adherence to diet such as fried and sweet food, processed and red meat, refined grains, and high-fat dairy products, reduces a persons likelihood of achieving older ages in good health and with higher functionality,according to the study published in the 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, said lead investigator Tasnime Akbaraly, from 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, Akbaraly said.
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 analysed 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.Researchers followed 3,775 men and 1,575 women from 1985-2009 with a mean age of 51 years from the Whitehall II study.
Using a combination of hospital data, results of screenings conducted every five years, and registry data,investigators identified mortality and chronic diseases among participants. The study determined that participants with low adherence to the AHEI increased their risk of cardiovascular and noncardiovascular death. Those who followed a Western-type diet lowered their chances for ideal aging.
