Every day, 330 American baby boomers turn age 60. Each of them desires to live a long and fulfilling life, full of productivity and vitality, and absent of disease and disability. This quest is why thousands of people just like you are becoming interested in anti-aging medicine.

Simply put, anti-aging medicine is advanced preventive health care based on the early detection, prevention, treatment and reversal of age-related dysfunction, disorders and diseases. The goal of anti-aging medicine is not merely to prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.

Some of the “secrets” to anti-aging aren’t really secrets at all, and they don’t require drugs or surgery. For example, abundant clinical and research evidence suggests consistent physical activity plays a key role in maintaining health and vitality as we age. Exercise is one of the most valuable forms of anti-aging medicine. Substantial health benefits occur with regular physical activity that is aerobic in nature (such as 30-60 minutes of brisk walking, five or more days a week). Additional health benefits can be gained through greater amounts of physical activity, but even small amounts of activity are healthier than a sedentary lifestyle. A number of recent studies reinforce this basic concept.

Men and women age 60-plus with higher levels of cardiorespiratory fitness live longer than unfit adults, and this correlation is independent of levels of body fat. Researchers at the University of South Carolina examined the associations between cardiovascular fitness, clinical measures of body fat, and death in older adults. The researchers studied more than 2,600 adults for a 12-year period, during which there were 450 deaths. The team found that those who died were older, had lower fitness levels, and had more cardiovascular risk factors than survivors. However, there were no significant differences in body fat measures.

Across a wide variance of body-fat levels (excluding the most obese), fit study subjects were found to have lower death rates than unfit subjects. Higher levels of fitness also corresponded to lower incidence of death from all causes. In their published report, the researchers comment: “The results add to the existing evidence that promoting physical activity in older adults provides substantial health benefits, even in the oldest old.”

The size of a man’s waistline and the muscle mass of his biceps provide s snapshot of mortality risk in aging men. S. Goya Wannamethee and colleagues from the Royal Free and University College Medical School (London) studied more than 4,100 men ages 60 to 79, and found that those with a waist circumference of less than 40 inches and above-average muscle mass in their upper arms were up to 36 percent less likely to die over a six-year period compared to those with bigger waists and smaller arm muscles. The researchers also found that the combination of waist size and arm muscle mass provided a far more accurate gauge of death risk compared to body mass index (BMI) measurements, which the team found was linked to mortality only among very thin men.

According to Dr. Shripad Tuljapurkar of Stanford University, “We are on the brink of being able to extend human lifespan significantly, because we’ve got most of the technologies we need to do it.” Dr. Tuljapurkar estimates that between 2010 and 2030, the average age of death will increase 20 years if anti-aging therapies come into widespread use. This would increase the average lifespan in industrialized countries from approximately 80 years to 100 years. Remember to check with your doctor before beginning any exercise program.

Is Your Full Figure an Increased Risk for Diabetes?

A new study suggest that women who have smaller breasts in their late teens and early 20s may enjoy a lower risk of developing type 2 diabetes later in life. However, many doctors have cautioned that the results may have more to do with obesity than they do with breast size alone.

……………...click & see

Researchers surveyed more than 92,000 women with an average age of 38, asking each of the participants to recall her bra size at the age of 20.

Women who recalled having a D cup or larger had about three times the risk of developing type 2 diabetes. Women who reported wearing B cup and C cup bras also experienced a higher risk than women who wore an A cup, even after figuring in age, body mass index (BMI), waist circumference, eating habits, family history of diabetes, physical activity level and pregnancies.

The study lead investigator believes that the correlation has something to do with how breasts develop during puberty. Puberty is a period marked by raised insulin resistance. Just as breast development is both accelerated and more pronounced in obese girls, their levels of insulin resistance may be as well.

However, if that is the case, many experts question why they should abandon the tried-and-true methods of evaluating type 2 diabetes risk by calculating their BMIs and evaluating lifestyles.

Disciplined Life Cuts Alzheimer’s Risk

[amazon_link asins=’0764225979,B009UGKEC4,0834102722,0742516857,B01N4W2ALJ,0804137382,0871230984,B00SGET3R8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’79d85594-2400-11e7-9fab-651d012bdfcd’]

CHICAGO: People who lead a good clean life – those who are conscientious, self-disciplined and scrupulous – appear to be less likely to develop Alzheimer’s disease, US researchers said .

The finding is the latest from a long-running study of nearly 1,000 Catholic nuns, priests and brothers by Robert Wilson of Rush University Medical Center in Chicago. The study appeared in the Archives of General Psychiatry .

Wilson and colleagues defined conscientiousness in the study as people who control their impulses and are goal-directed. These people are often considered dependable. People in Wilson’s study did not have dementia when the study started in 1994.

The researchers asked the volunteers to rank themselves on a five-point scale according to a 12-item inventory, with questions such as “I am a productive person who always gets the job done.” From this, they derived a conscientiousness score, based on a scale of 0 to 48. The average score was 34.

They were also given various medical and neurological exams, including cognitive testing. Follow-up tests were done each year through 2006. A total of 176 people developed Alzheimer’s disease during the study.

People who were highly conscientious – those in the 90th percentile with scores of 40 or higher, had an 89% lower risk of developing Alzheimer’s disease than those who ranked in the 10th percentile.

Pumpkin may treat diabetics

[amazon_link asins=’B01N28AC6V,B01NAYXX09,B072BNFST7,B0738SB5ZQ,B01CQ3QU2K,B00HH168QA,B01N4VCPCH,B07F3GN9Y9′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’8b11cdcf-8d50-11e8-90c3-2f42b221c966′]

The common vegetable Pumpkin will now be more tastier than ever as Chinese scientists have claimed that it can “drastically” reduce the need for daily insulin injections for millions of diabetic patients worldwide.

Scientists have discovered a compound in pumpkin that has been known to promote the regeneration of damaged insulin-producing beta cells in diabetic rats, thereby improving the level of insulin in their blood.

Laboratory data showed that diabetic rats that had been fed pumpkin extract had only five per cent less plasma insulin and eight per cent fewer insulin-positive cells than normal healthy rats, according to a research paper published this week in the US-based Journal of the Science of Food and Agriculture.

The researchers fed 12 diabetic rats and 12 normal rats either a normal diet or a diet supplemented with pumpkin extract for 30 days.

On average, the rats receiving the pumpkin supplements experienced a 36 per cent increase in plasma insulin compared to the untreated rats, Professor Xia Tao, the paper’s lead author and a teacher at Shanghai‘s East China Normal University said.

However, Xia, a professor at the College of Life Science, emphasised that further research was needed to evaluate the effects in human beings.

“But I tend to believe pumpkin extract could also promote regeneration of pancreatic beta cells in humans,” he was quoted as saying by China Daily

7 Diet Misconceptions

[amazon_link asins=’B076QFTJKT,B06XY8XDHR,B00FI1T0P2,B00FB2W6AY,B0186IX13A,B077G6QX7M,B00W5TUS4M,B077B5CSCR,B00FJPG5C8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’b29c6b41-0e78-11e8-a78c-1f55e33655d4′]

Confused about how to lose weight? All the common diet myths are debunked here!

Weight loss can be difficult, no thanks to popular misconceptions that have the ring of truth but can actually work against you. Among the more common myths:

1. Desserts are forbidden.
The truth is, there’s room in your diet for any kind of food, especially the ones you love most — as long as you control your total caloric intake (and grams of carbohydrate, if you tally them). Denying yourself your favorite foods can lead to binge eating and, ultimately, discouragement.

2. You have to lose a lot of weight to make a difference.
The closer you can get to an ideal weight, the better, but small, sustained improvements at the beginning of a weight-loss program have the biggest impact on your health. Studies show that losing just 5 to 10 pounds can improve insulin resistance enough to allow some people with type 2 diabetes to quit medication or injections.

3. What you eat matters more than how much.
Both matter, but recent research finds that the number of calories in your food is more important than where they come from. Example: A bagel might seem healthier than a doughnut hole, but dense bagels have the calorie content of six slices of bread. As long as you’re not eating too much fat in other foods, the doughnut hole wins.

4. If you work out, you can eat whatever you want.
That’s robbing Peter to pay Paul. You can’t lose weight if you reduce calories in one way but increase them in another.

5. Skipping meals makes you lose weight fast.
Actually, studies show that people who skip breakfast tend to be heavier than people who don’t. And skipping meals tends to make you overeat later. If you have diabetes, it’s important to keep up a steady intake of small portions of food throughout the day to keep your blood-sugar levels stable and reduce the risk of hypoglycemia.

6. Starches are fattening.
If you are insulin resistant, your body may find it easier to convert carbohydrate calories to fat than to burn it as energy, but the fact remains that starches (and other carbohydrates) are less dense in calories gram for gram than other types of food. The main issue is calories, so if you load starchy foods with fat — sour cream and butter on a baked potato, for instance — or eat them in large quantities, the caloric load can add up.

7. You should never eat fast food.
Never say never. Fast food can be worked into your meal plan if you choose well. Opt for grilled foods instead of fried, avoid or scrape away high-fat condiments like mayonnaise, and share those French fries to keep portion size down.
