Want to join the estimated 1 million people in the U.S. who are expected to have lived to 100 or older by the year 2050? Happily, recent scientific advances have made it more possible than ever to take control of the aging process. By following large population groups over many years, researchers have documented specific lifestyle changes that can extend life expectancy from one to eight years; add them together and you could gain 20 years or more. They range from the mundane -- flossing every day -- to the ambitious -- lowering your body mass index below 22.

And let's face it: When we know what works, we're much more likely to do it. Wouldn't you be less likely to skip your morning run knowing that vigorous exercise three times a week adds five years to your life? Well then, here you go. By following these seven simple suggestions, you'll be set to join the ranks of future centenarians.

1. Stop sitting around.

What the research shows: In the past year, several studies on the effects of sitting startled the medical field by demonstrating that sitting for long hours is bad for you even if you're not overweight and you exercise vigorously at other times. Yep, that's right: When researchers study only healthy people who exercise regularly, they still find that those who sit a lot each day have higher blood pressure, greater risk of diabetes, and larger waist circumference than those who sit less.

"Sitting for extended periods of time has been linked to increased risk for heart disease, obesity, and maybe even increases risk of dying from cancer," says Dr. Jonathan Rich, an osteopathic internist at Mercy Medical Center in Baltimore.

Even scarier: One study followed 17,000 Canadians and found that those who sat the most were more than 50 percent more likely to die during the follow-up period, regardless of age, physical activity level, and whether or not they smoked. Another study found that adults who watched more than three hours of TV a day had significantly poorer cardiovascular health, again even when other health conditions, weight, and physical activity level were taken out of the mix.

Researchers are still studying the issue, but experts are warning of a "physiology of inactivity" that seems to set in, causing your body to release dangerous molecules that affect how you process fats and sugars.

How to make this work for you: Change your habits. Watch TV or use the computer while bouncing on an exercise ball or walking on a treadmill. Work standing up with your computer on a high desk or counter. Before your favorite show comes on, get out a yoga mat and some hand weights and resistance bands and do some gentle stretches and strength training while you watch. If you are sitting for a long while, pause and take breaks to stretch or walk the dog. Even rocking in a rocking chair keeps you moving a bit.

Rich suggests using wearable technology, such as a pedometer, to count your steps, and aiming for about 10,000 steps per day.

"Some research has shown that even modest exercise, 15 to 20 minutes a day, can extend your life," says Rich. "I always recommend trying to do it throughout the day, instead of saving it all up for the gym."

That means standing and walking as much as possible throughout the day, even if all you do is park your car further away in the parking lot, he says.

2. Drink pomegranate juice.

What the research shows: Positive studies on pomegranate juice just keep coming. In the past six years, researchers have found that eating pomegranates or drinking the juice may prevent hardening of the arteries, reduce blood fats in diabetics, prevent gum disease, and slow the growth of several types of cancer, including lung cancer. Most of this has come from preliminary studies involving mice, or small studies involving humans -- but the sheer number of studies with similar results, coming out of different countries, is impressive.

How to make this work for you: Drink one glass of pomegranate juice a day, or eat the fruit itself, which has the benefit of including the natural fiber in the seeds. Some people don't like the taste of pomegranate, which can be sour. If that's you, add honey or mix into a smoothie, or add the seeds to a fruit salad with yogurt.

You can also take a supplement, which certainly makes things easier. But most research studies have been done with the fruit itself, so the benefit of supplements isn't as well established.

3. Go green and orange for dinner, red and blue for dessert.

What the research shows: Ongoing studies at Tufts University's Human Nutrition Research Center on Aging and other institutes show that certain fruits and vegetables are nutritional powerhouses, packed with disease-fighting phytochemicals, with the potential to ward off cancer, protect against heart disease and diabetes, and even slow aging itself -- at least to some degree.

Blueberries, for example, have been shown to reverse balance, coordination, and memory problems. Cranberries deactivate bacteria and prevent infection. Broccoli made headlines last year when it was shown to ward off prostate cancer in men who were at risk.

How to make this work for you: Anti-aging "superfoods" give themselves away by virtue of their color: The dark green of broccoli and kale; the rich orange of squash, sweet potatoes, and mangos; the deep purple of grapes; and the rich reds, blues, and purples of berries all indicate these foods are essentially medicine in food form. Nutritionists say the best thing to do is "eat a rainbow," choosing brightly colored foods and steering clear of those that are light-colored or colorless. Here's a quick color-coded guide:

  • Red = lycopene

  • Orange/yellow = carotenoids

  • Green = lutein and chlorophyll

  • Blue/purple = anthocyanins

The exception: White vegetables like garlic and onions contain important phytochemicals too. In addition, cruciferous vegetables including broccoli, cauliflower, and Brussels sprouts, which are eaten in "bud" form before they leaf out, have chemicals called indoles that protect against cancer; and leafy greens like spinach are rich in folate, which protects the heart and prevents birth defects and colon cancer.

4. Put on your dancing shoes.

What the research shows: Learning a new skill, particularly one that's fairly complex and involves coordination between the brain and the body, is one of the best ways to protect memory and preserve cognition, experts say. But the recommendations can get much more specific than that. In one recent study, researchers at McGill University in Canada found that people who joined a class to learn the sophisticated steps of Argentine tango performed significantly better on cognitive tests and showed improved balance, posture, and motor coordination than a comparative group who walked instead of danced.

How to make this work for you: Commit one night a week to learning something new that challenges you both mentally and physically. Sign up for tai chi, join a Zumba class, or learn to hula hoop. The commitment required to reap this benefit isn't as daunting as you might think. In the tango study, for example, participants danced for just two hours once a week.

One more thing: Getting moving has benefits in and of itself. In a groundbreaking study earlier this year, researchers found that when people with mild dementia participated in aerobic exercise for 45 to 60 minutes four days a week, they showed significant gains in thinking speed and memory, compared with a control group that didn't exercise and continued to experience mental decline.

5. Cut calories.

What the research shows: The science behind calorie restriction, as it's known, is eye-opening. Studies in animals and people show that reducing calorie intake between 15 and 30 percent of normal levels leads to a host of anti-aging benefits. Experts believe calorie restriction lowers metabolic rate and causes the body to generate fewer damaging free radicals. It also has a beneficial effect on the thyroid, which regulates your overall metabolic rate.

The result: startling drops in cardiovascular risk factors, lower cancer rates, and -- plain and simple -- longer life. The benefits are more than physical; one recent German study found that calorie restriction boosted memory and cognition. Researchers theorized this was because it reduced insulin resistance and inflammation, both of which are linked to age-related cognitive decline.

How to make this work for you: Calorie restriction isn't as daunting as it sounds. The secret is to cut simple carbs, fats, and sugar. Serve red meat sparingly, and replace it with turkey, fish, and eggs. Eat more beans and legumes. For dessert, try strawberries or fruit parfait. For snacks, eat nuts or whole wheat crackers. Portion size is key, too, since calorie cutting is more important than eliminating certain foods.

6. Boost brainpower with brain-healthy fats.

What the research shows: Research into the importance of omega-3 fatty acids continues to pour in, and researchers have begun to better understand the vital role these fats play in brain health. According to neurologists, two thirds of your brain is composed of fats. Myelin, the protective sheath that covers neurons, is 70 percent fat -- and the membranes of neural cells are composed of fatty acid molecules as well.

The bottom line: Your brain cells depend on fatty acids to maintain their ability to communicate. Studies have shown omega-3 fatty acids boost memory, reduce depression and other mood disorders, protect cardiovascular health, and reduce cancer rates. As far as brain health, the benefits kick in quickly: In one recent study, participants 55 and up with memory problems took omega-3 fatty acids for six months and scored many fewer errors on learning and memory tests than those taking a placebo.

How to make this work for you: The body can't make its own omega-3 fatty acids; you have to get them from food, so boost your diet with as many fatty acids as you can. Stock up on ground flaxseed (whole seeds are not easily digested and pass right through), which is becoming increasingly available in grocery stores, and add it to everything you can think of. Sprinkle it on oatmeal or cereal; add it to a bowl of yogurt and fruit or a smoothie; stir it into soup or sprinkle on a salad.

Adorn your table with a decorative decanter for olive oil (it keeps its potency best in an opaque bottle) and drizzle it over veggies and salads or dip your bread into it.

Keep a jar of fish oil capsules on your kitchen counter and take one as you begin each meal. (This way you're less likely to have the "fish burps" that annoy some folks.) Because fish oil has been purified for mercury and other heavy metals, you don't have to limit your intake the way you do with seafood.

But eat seafood too; some studies have shown that populations that eat a diet high in fish are much healthier and longer-lived than populations that don't. Algae is high in DHA, one of the key omega-3 fatty acids, and some people incorporate algae-based supplements, such as spirulina, as well.

7. Protect your posture.

What the research shows: Sitting and stress are the enemies of the spine, aging experts say. Why? Both tend to make us hunch forward, head jutting forward between rounded shoulders. But poor posture does much more harm than make you look old, researchers say. Rounded posture compresses the nerves and disks in the spine, restricting blood flow to the supporting muscles and leading to neck, shoulder, back, and hip pain.

"The way you stand, walk, and sit affects the health of all of your body's systems: your organs and glands, the strength and flexibility of your 600-plus core and surface muscles, breathing capacity, and your ability to maintain healthy joints and tendons," says exercise physiologist Alice Ann Dailey, author of Dailey Strengthening: 6 Keys to Balance Core Muscles for Optimal Health.

In addition, recent research has focused on the connection between poor posture and breathing disorders and circulatory health. Some doctors have patients do this experiment: While hunched forward, try to draw a deep breath into your lungs. You'll find it's very hard to do.

Over time, poor posture is also a major contributor to balance problems and falls -- a leading cause of injuries for those 65 and older. However, good posture can lower the possibility of you losing your balance, Dailey says.

How to make this work for you: The key is to relearn how to stand, sit, and lie so your spine is stretched straight and tall, says Esther Gokhale, author of 8 Steps to a Pain-free Back, who teaches posture therapy classes in Palo Alto, California. To put Gokhale's principles into practice, roll your shoulders back and down, opening up the chest, and "stack" the spine directly over the hips, stretching it as tall as possible. Tuck your ribs back against your spine, letting your pelvis come naturally forward.

Unfortunately, following the commandment to "stand up straight" is more difficult than it sounds for those who need to undo years of damage. In this case, postural therapy, a type of physical therapy, can help you strengthen and rebalance specific muscles necessary to hold the spine in the correct posture. Some physiotherapy experts also advocate "inversion therapy," in which you use a device to hang upside down to reverse the effects of gravity. Practicing yoga can help you achieve the same goal through inverted postures such as headstands, shoulder stands, and others.

An additional benefit: Some participants in postural therapy say they've regained as much as an inch in height lost to aging.

I have no desire to live to 100. The great majority of very elderly people have significant disabilities, either physical, mental or both. The dancer in her 90s and the car-repairing 102-y.o. (mentioned in previous comments) are in the news for a reason: they are very unusual. You may live to 100, but you have a very good chance of not living your life as you wish it to be. My mother is 94, has dementia and is physically pretty healthy. She receives excellent care in a frightfully expensive facility. I know that she would not want to live the way she does now--in diapers, perpetually confused, and among strangers (even though she's been there over a year, they will always be strangers to her.) These cheerful "You can live to be 100!" articles are so misleading, starting with the happy couple at the top of the article--they are in their early 60s, at most. Are you prepared to be retired for 30-40 years? If not, what kind of job are you going to have in your 70s-80s-90s? Have you had lots of children so there are enough people in the workforce to support Social Security and Medicare for your decades-long retirement? I can't help hoping that I don't live as long as my mom has. We all want to have great health and independence, and then die in our sleep at age 100. Don't count on it.

My Great-Grandma lived to 104 & won a dance Contest in LA when she was 91 & made the front page headlines of the LA times. She was very active danced & shopped for the "old People in her Neighborhood". She had 12 kids & went to the hospital only once 3days before she passed. She was so positive & awesome. You couldn't call her Great-Grandma; she didn't want anyone to know she was that old GG was her name.

It is said the amount of stress you have to deal with is not as significant as how well you can bounce back from it. Positive attitude counts as well as good genes & good luck! The Dr who invented Valium lived till 97! I wonder if he took it regularly at moderate levels. May be just relaxed is the best medicine!!!

over 5 years, said...

The number one thing is genetics....If you are fortunated enough to have been born to parents that have had a long life...chances are you will also ...all things being equal. . It doesn't even mention drinking wine at night that also relaxes and relieves stress... This article was written by someone who only has read articles and has not actually lived long enough to figure all this out.
