Longevity News & Review

For The Bali Times
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 22,000 physician and scientist members from 105 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, M.D., D.O., A4M President, and Dr. Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary.
In Women, More Zinc May Lower Diabetes Risk
Zinc is a plentiful trace element in the body, and it mediates many physiological functions. Qi Sun, from the Harvard School of Public Health, and colleagues investigated the intake of zinc in relation to risk of type-2 diabetes in US women. They assessed data collected on participants of the Nurses’ Health Study, comprised of 82,297 women, ages 33 to 60 years at the study’s start. Specifically, the team analyzed the subjects’ dietary intakes of zinc and other nutrients in for a period of 24 years. The researchers found that those women with the highest average daily intake of zinc were 10-percent less likely to develop type-2 diabetes, while women with the highest average total intakes slashed their risk by 8 percent. Further, after factoring in other confounding factors, they showed that increased intake of zinc was associated with a reduction in type-2 diabetes of 28 percent. The team concludes that: “Higher zinc intake may be associated with a slightly lower risk of type-2 diabetes in women.”
Dr Klatz remarks: Type-2 diabetes is a leading cause of long-term dependence and disability. In the United States, the disease affects 209 million people; in the EU, 19 million residents have the condition. With the numbers of cases of type-2 diabetes to rise as the global population ages, it is critically important to identify effective nutritional interventions that may slash the risk of onset of the disease.
In Women, B-Vitamins May Prevent Age-Related Vision Loss
Age-related macular degeneration (AMD) is the leading cause of legal blindness for people age 55-plus in the Western world. William Christen, from the Brigham and Women’s Hospital and Harvard Medical School in Massachusetts, and colleagues, tested a theory that AMD may be correlated to blood levels of homocysteine, an amino acid linked to dysfunction of the blood vessel lining; and that supplementation with vitamins B6 and B12, and folic acid may reduce homocysteine levels and reverse this blood vessel dysfunction. The team recruited women with heart disease or at least three risk factors for the disease; of these, 96 percent did not have AMD at the start of the study. The women were randomly assigned to receive either placebo or a combination of folic acid (2.5 mg per day), vitamin B6 (50 mg per day) and vitamin B12 (1 mg per day). Over the course of 7.3 years of intervention and follow-up, the combined B vitamin supplement was associated with a 34-percent lower risk of any AMD and a 41-percent lower risk of visually significant AMD. The researchers note that: “The beneficial effect of treatment began to emerge at approximately two years of follow-up and persisted throughout [the study].”
Dr. Goldman observes: Approximately 25 to 30 million people worldwide are affected by AMD, and with the aging Baby Boomer population, the numbers of cases of AMD may rise to triple by 2025. These study findings provide strong evidence to support a potentially beneficial effect of folic acid and B vitamin supplements to prevent this condition.
Cinnamon May Improve Blood Sugar Levels
Joanna Hlebowicz, from Malmo University Hospital in Sweden, and colleagues recruited 15 healthy men and women subjects, average age of 24.6 years, with an average BMI of 22.5 kg/m2 and no history of diabetes. The researchers then assigned each to randomly consume 300 grams of rice pudding with zero, one or three grams of cinnamon. All of the participants consumed all the meals in a random order, with one week between each. Ingesting the spice led to reductions in blood insulin levels, the hormone responsible for controlling blood sugar levels, and increased levels of a peptide (GLP-1) reported to work by delaying the emptying of the stomach (gastric emptying). The team writes: “There seems to be a relation between the amount of cinnamon consumed, the delay in gastric emptying and the reduction in postprandial blood glucose concentrations.”
Comments Dr. Klatz: There have been a number of studies suggesting a therapeutic role for cinnamon for diabetes management. However these benefits remain unclear due to the small numbers of study subjects involved. This study offers important further data that may lead to uncovering whether cinnamon supplementation may be of real and tangible benefit for type-2 diabetes.
Anti-aging medicine is the fastest-growing medical specialty throughout the world and is founded on the application of advanced scientific and medical technologies for the early detection, prevention, treatment and reversal of age-related dysfunction, disorders, and diseases. It is a healthcare model promoting innovative science and research to prolong the healthy lifespan in humans. As such, anti-aging medicine is based on solid scientific principles of responsible medical care that are consistent with those applied in other preventive health specialties. The goal of anti-aging medicine is not to merely prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.
