There is no one-size-fits-all approach to eating for healthy aging, but there is plenty of evidence in favor of dietary patterns focused on plant-based, less-processed foods Chan School of Public Health’s Marta Guasch-Ferré and other researchers quoted in an August 12 MarthaStewart.com article
“I wouldn’t say there’s one food in particular that stands out, not a superfood that will solve all your problems. It’s a combination,” Guasch-Ferré, adjunct associate professor in the Department of Nutrition, said in the article
She said that vegetables, fruits, whole grains, and vegetable oils have been associated with healthy aging, better cognitive function, and better physical and mental health. She also suggested eating legumes to help prevent age-related muscle loss and added that moderate amounts of fish or eggs can be part of a healthy protein approach in midlife
Importantly, healthy dietary patterns don’t need to be restrictive, Guasch-Ferré said. They should be sustainable for a lifetime
