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 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
Diabetes Linked to Cognitive Function Decline
A new study evaluated whether diabetes mellitus (DM) is a risk factor for mild cognitive impairment (MCI), a condition that occurs just prior to the onset of dementia. Rosebud Roberts, from the Mayo Clinic (Minnesota USA), and colleagues studied a group of men and women, ages 70 to 89, and found that those with MCI were at a greater risk of developing diabetes before age 65, having diabetes for 10 or years longer and suffering from its complications.
Dr Klatz remarks: These findings suggest an association of mild cognitive impairment with earlier onset, longer duration, and greater severity of diabetes. The notion that diabetes may be a risk factor for MCI suggests that patients, through the prudent guidance of their physicians, may benefit from preventive steps to offset their risks of the onset of type-2 diabetes.
Omega-3 Fatty Acids Slash Risk of 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. Astrid Fletcher, from the London School of Hygiene & Tropical Medicine (United Kingdom), and colleagues have found that an increased consumption of the omega-3 fatty acids slashes the risk of AMD by 70 percent. Fish such as mackerel, lake trout, herring, sardines, albacore tuna and salmon, contain high levels of omega-3s. The researchers state: â€œEating oily fish at least once per weekâ€¦ halves the risk for AMD.â€
Dr Goldman observes: AMD causes central vision loss and leaves only peripheral vision. Early detection has been the primary mode of prevention, in that treatment or rehabilitation can be key if implemented in the initial phase of the disease. This study suggests a role for omega-3 fatty acids in prevention or risk reduction, and a potential utility for supplementation of these nutrients to actually improve retinal health.
Low Vitamin D Linked to Increased Risk of Death
Johns Hopkins University (Baltimore, Maryland USA) researchers have completed a study suggesting that low blood levels of Vitamin D are associated with a 26-percent increased risk of death from any cause. Erin Michos and colleagues analyzed data from 13,331 adults collected during a 6-year period after which the subjects were followed for 9 years. People with Vitamin D levels of less than 17.8 ng/mL had a 26% increased rate of death from any cause, compared to people with the highest Vitamin D levels (more than 32.1 ng/mL). State the researchers: â€œOur results make it much more clear that all men and women concerned about their overall health should more closely monitor their blood levels of Vitamin D, and make sure they have enough.â€
Dr Klatz remarks: Previously, Vitamin D deficiency has been linked to osteoporosis and certain cancers. This study now demonstrates that low Vitamin D levels contribute to an increased risk of death from any cause. Simply by boosting Vitamin D levels, via increased consumption of foods rich in the vitamin, by supplementation, or perhaps even by a 15-minute daily exposure to sunlight, an individual may be able to significantly impact their risk of death.Filed under: Health
