Longevity News and Review provides readers with the latest information in breakthroughs pertaining to the extension of the healthy human lifespan. These news summaries are compiled by the American Academy of Anti-Aging Medicine (A4M; www.worldhealth.net), a non-profit medical society composed of 20,000 physician and scientist members from 90 nations, united in a mission to advance biomedical technologies to detect, prevent, and treat aging related disease and to promote research into methods to retard and optimize the human aging process. Dr. Ronald Klatz, A4M president, and Dr. Robert Goldman, A4M chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary

Low Vitamin D Increases Risk of Type-2 Diabetes

Low vitamin D status has been suggested as a risk factor for type-2 diabetes. Paul Knekt, from the National Public Health Institute in Finland, and colleagues, completed a study involving men and women aged 40 to 74 years, all of whom did not have diabetes at the study’s start, and followed the participants for a period of 22 years. The team found that men with the highest serum vitamin D levels were the least likely to develop type-2 diabetes later in life. The researchers explain that a lack of vitamin D interferes with insulin secretion, and thus they conclude that: “The results support the hypothesis that high vitamin D status provides protection against type-2 diabetes.”

Dr Klatz remarks: Over 20 million people in the United States, or 7 percent of the population, have diabetes; in Europe, the disease affects 19 million men and women. Around the world, experts predict the numbers of cases of type-2 diabetes to rise as the global population ages. This study supports a potential interventive role for increased intake of vitamin D to ward off the onset of the disease.

Secrets of Staying Active as We Age
A carefully tailored combination of moderate exercise and nutritional supplementation could help older people maintain an active lifestyle for longer. Gladys Pearson, from the Manchester Metropolitan University, and colleagues studied 60 healthy, independent-living adults aged 65+ for a 3-month period. The participants were randomly divided into groups who participated in different regimens of physical exercise (low or high resistance, twice a week) and nutritional supplementation (protein and carbohydrate supplements). The team found that the greatest benefits were yielded by a combination of “appropriate supplements coupled with low-intensity exercise.” Commenting on their findings, the researchers note: “Maintaining muscle performance … can offer older people real improvements in their quality of life.”

Dr Goldman observes: Aging is associated with lower muscle mass and an increase in body fat. This study suggests that by maintaining our physical fitness and physique as we age, we thereby enhancing our abilities to keep to a productive and vital lifestyle.

Low Calcium Levels Linked to Overweight

Calcium has been suggested to exert an effect on body weight, via two mechanisms: the first, involving hormones that play a role in fat buildup; and the second, a correlation between increased dietary calcium and an improved capacity to bind more fatty acids in the intestines, thereby inhibiting fat absorption. Milena Baptista Bueno, from the University of Sao Paolo (Brazil), and colleagues studied 1,459 adults aged 20 to 59. The team found that those with the lowest average intakes of calcium (less than 264.9 mg per day) were 24 percent more likely to be overweight.

Dr Klatz remarks: Worldwide, over 300 million adults are obese, according to statistics from the World Health Organization and the International Obesity Task Force. This study will encourage further research to uncover whether weight gain may be offset by the simple dietary step of increasing one’s daily calcium intake.
