One of the largest, longest studies of aging found one more reason to stay trim and active: It could greatly raise your odds of living to at least age 85.

Learn the nutrition secrets of the planet's oldest people with these 12 simple steps to a longer, healthier life.

Hawaii is home to more 100-year-olds per capita than any other state. Researchers are learning why.

Learn five nutritious habits of the planet’s healthiest countries—then use our tips to give your diet a boost.

With an average life expectancy of 78 years for men and 86 years for women, Okinawans are among the world's longest lived people. More important, elders living in this lush subtropical archipelago tend to enjoy years free from disabilities. Okinawans have a fifth the heart disease, a fourth the breast and prostate cancer, and a third less dementia than Americans, says Craig Willcox of the The Okinawa Centenarian Study.

Researchers are studying 1,200 Hawaii men who will be 91 or older next year in search of clues to a long, healthy life.

These islanders stay trim and fit well into their nineties, thanks to a diet of low-cal vegetables and high-protein soy.

The simple anti-aging strategy of centenarians.

Fad diets may help you shed a few pounds. But to enjoy more energy, balance mind and spirit, lose the weight and keep it off, you need the world's healthiest eating plan.

Boost your health and drop pounds with these powerful eating strategies from around the world.

The first thing you need to understand about the Okinawa Diet Plan is that it doesn't mean restricting yourself to boiled pork, purple sweet potatoes and bitter melon, though you may learn to love these Okinawan favorites.

New research suggests that a long life is no accident. So what are the secrets of the world's centenarians?

... an analysis of dietary data from a 28-year study of Okinawan centenarians shows a key to healthy aging is maintaining healthy lifelong weight with diet and exercise.

Some Asians seem to have discovered the fountain of youth. So what does it take to reach 100?

The grandparents live past 100, but after too many burgers, the islands' next generation may not make it to middle age.

On Okinawa where the diet consists of soy, vegetables and small amounts of fish, meat and rice there are 34 centenarians for every 100,000 people -- more than triple the U.S. rate.

Big-city stress and fast food are threatening the way of life in a village that produces scores of healthy seniors.

Juan Ponce de Leon and James Hilton had it all wrong. The fountain of youth isn't in Florida, where 16th-century Spanish explorer Ponce de Leon went searching for it. And Shangri-la isn't stuck way up in the Himalayas, where Hilton, author of Lost Horizon, placed his fictional paradise, whose inhabitants never aged.

No country on earth has a longer life expectancy than Japan, and nowhere in Japan do people live longer than they do on sun-drenched Okinawa, a coral-ringed island just north of Taiwan.

Heart disease and strokes are rare. Cancer rates are low. Instead of being shunted into homes and forgotten about, old people are out and about.

A new book, The Okinawa Program, by Bradley Willcox, MD, D. Craig Willcox, PhD, and Makoto Suzuki, MD, is the first solid, long-term study of the longest lived population in the world, in the Shangri-La of Okinawa. The authors conclude that we could all add high quality years to our lives if we just lived like the Okinawans do.

A few years ago scientists were studying Cretans for clues to their longevity. The conclusion: high consumption of olive oil, fruits, grains, and vegetables, plus lots of hard physical work, was what kept heart disease rates low on Crete and in other parts of Greece. Now another island, Okinawa, is in the news, thanks to a best-selling book called The Okinawa Program, by researchers Bradley and Craig Willcox and Makoto Suzuki.

Bradley Willcox ... and his twin brother Craig ... have spent seven years assessing the habits of Okinawans to determine why they have the world's longest disability-free life expectancy.

Results of a 25-year study focusing on Okinawans and published in the United States confirm what some health professionals in Hawaii have suspected.

On Okinawa, the elderly are active and appear youthful beyond their years. There, you might see a 103-year-old ride his motorcycle to karate class, or a 101-year-old tending her garden before taking her vegetables to market.

It's tried-and-true advice -- eat better, get some exercise, quit smoking, and you'll live longer. But how much longer? A new study shows you might just add a full decade -- 10 years of good-quality living.

Dr. Bradley J. Willcox, author of "The Okinawa Program."; Dr. Thomas Perls, principal investigator, New England Centenarian Study; and Neenah Ellis, producer of the series, "One Hundred Years of Stories." discuss longevity.

The Okinawa Centenarian Study, which began in 1976, concentrated on genetics and lifestyle. Over 600 centenarians and elders in their seventies, eighties and nineties were examined.

"The Okinawa Program" not only reveals the lifestyle practices that keep Okinawans healthy and living longer, but it also offers readers a four-week plan with recipes, stress-relieving tips and information on beneficial herbs.

Diane Sawyer interviews Dr. Bradley Willcox regarding "The Secrets to Okinawan Longevity".

"Modern medicine is allowing more and more people to live longer. But it is an unhealthy long life, and that’s not good."

There are six times as many centenarians per 100,000 people in Okinawa than in the United States, and 94 percent of their lives are spent free from disability. Rates of heart disease and breast and prostate cancer in Okinawa are less than a quarter of what they are in the United States.

It’s not the genes that you’ve got that matter it’s what you do with them.

Get healthy. Live longer. Go Okinawan.

No one wants to get old and wrinkled, but in America the quest for perpetual youth is an obsession. Which might explain the instant popularity of a new book, The Okinawa Program, based on a landmark 25-year study of the people of Okinawa, a chain of islands off the coast of Japan that many regard as the real Shangri-la.

The islanders of Okinawa live longer than anyone else on the planet. And they stay fit, active and happy long into old age. Now a new book reveals their secrets.

Unusually long, rich life spans lure doctors to see why the islanders thrive.

Okinawans, the world's longest-lived people, have a lot to teach Americans on the art of reaching 100.

What do the Okinawans know and do that we don't? Is it in their genes? Can we emulate them?

There's no Shangri-La, but Okinawa comes pretty close to being that mythical land of perpetual youth.

Okinawans not only live longer but they also remain healthier and more active until very late in life, enjoying what researchers call an extended "health span."
