Fad diets come and fad diets go. Experts say ignore the fads. A simple dietary change of eating more legumes (beans, peanuts, etc.), nuts, whole grains, fruits and veggies while cutting back on red meat and processed foods can extend life expectancy.
Think it’s too late to start? Nonsense. Changing to an optimal diet even as late as age 80 can have a positive impact on your longevity.
