“There is a critical distinction between living longer and living healthier and longer,” says Jill Carnahan, MD, a Colorado-based functional medicine expert. “What does longevity mean? It’s about optimal aging, in which your brain, body, mind, and spirit are all functioning at their best, well into your later years.” So you not only have a high quantity of life, but a high quality of life. The good news: Healthy aging is less about genetics and more about your lifestyle. And it’s never too late to make changes that will have a long-lasting impact. Research done by Dan Buettner, National Geographic fellow and author of The Blue Zones and The Blue Zones Kitchen, looked at certain areas of the world with the highest number of centenarians—people living well into their 100s, free of disease, disability, and dementia. Buettner dubbed these five regions the “Blue Zones”:

Sardinia, ItalyOkinawa, JapanLoma Linda, Calif.Ikaria, GreeceThe Nicoya Peninsula, Costa Rica

“In studying the people of these regions, we effectively found the common denominators that are the keys to longevity,” Buettner says. “If you can set up your life so you move more, eat less, socialize more, and live out your purpose, you can get the most good years out of your body and mind.” He adds that making these lifestyle changes will not only help you feel better, but will also help you to avoid heart disease, diabetes, stroke, and dementia.

He adds that a bean and grain together—like a lentil and barley stew—are a whole protein, with all of the amino acids of a piece of meat.

That’s why Dr. Carnahan recommends daily meditation, which can be done through a guided meditation app, and taking Epsom salt baths, which help you to relax.

There is a reciprocal effect, in which adults are taking care of their aging parents, grandparents are taking care of the kids—essentially, everyone in the family unit is being supported and loved.
