Switching to a Healthy Diet can Add 10 Years to Life

“Our results indicate that for individuals with a typical Western diet, sustained dietary changes at any age may give substantial health benefits, although the gains are the largest if changes start early in life,” say the researchers.

Depending how many healthy dietary “switches” are made and maintained and the amounts consumed, a 20-year-old man in the U.S. could extend his life up to 13 years, and a 20-year old woman by 11 years.

That number drops with age but changing from a typical diet to the optimized diet at age 60 years could still increase life expectancy by 8 years for women and 9 years for men, and even an 80-year-old female could gain more than three years with healthier food choices.

Until now, research in this area has shown health benefits associated with separate food group or specific diet patterns, while focusing less on the health impact of other diet changes. The statistical ‘modelling’ approach used in this study bridges that gap, the researchers say.

“Understanding the relative health potential of different food groups could enable people to make feasible and significant health gains,” they conclude.

I started later in life. Looks like it may not be too late.
