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 24,000 physician and scientist members from 110 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 insightful commentary.
Mediterranean Diet Helps to Preserve Memory
Georgios Tsivgoulis, from the University of Athens (Greece), and colleagues analyzed data collected on 17,478 African-American and Caucasian men and women, average age 64 years, enrolled in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study. The researchers reviewed dietary information to see how closely the participants adhered to a Mediterranean diet. The team also administered tests to measure memory and thinking abilities over an average of four years. Seven percent (7%) of the participants developed impairments in their thinking and memory skills during the study. The investigators found that in healthy people, those who more closely followed the Mediterranean diet were 19% less likely to develop problems with their thinking and memory skills. The study authors conclude that: “Higher adherence to [Mediterranean Diet] was associated with a lower likelihood of [incident cognitive impairment] independent of potential confounders.”
Dr. Klatz observes: “Previously, a number of studies have shown that adherence to a Mediterranean diet – rich in olive oil, nuts, as w ell as fruits, vegetables, and legumes, and limited amounts of dairy products, red meat, soda drinks, processed meats, and sweets – inversely associates with cardiovascular risks. This data finds that consuming a Mediterranean diet may curtail aging-related memory loss.”
Vitamin D Promotes Post-Exercise Recovery
Tyler Barker, from The Orthopedic Specialty Hospital (Utah, USA), and colleagues enrolled 14 recreationally active adults to participate in an experiment in which one leg was used to measure muscle performance while the other acted as control, and compared to blood levels of vitamin D as well as other blood measurements. Muscle weakness was observed in then exercise leg (as compared with the control leg) post-exercise, with blood levels of vitamin D inversely predicting muscle weakness both immediately and several days after exercise. The study authors report that: “we conclude that pre-exercise serum [vitamin D] concentrations could influence the recovery of skeletal muscle strength after an acute bout of intense exercise.”
Remarks Dr. Goldman: “In that research efforts seek to identify effective approaches to promote muscle recovery after intensive exercise, this team reports that increased blood levels of Vitamin D may provide assistive benefits.”
Soda Raises Diabetes Risk
Dora Romaguera-Bosch, from Imperial College London (United Kingdom), and colleagues at the InterAct consortium, studied associations between consumption of juices, nectars, sugar-sweetened soft drinks, and artificially-sweetened soft drinks with diabetes incidence among 15,374 participants from eight European countries involved in the EPIC (European Prospective Investigation into Cancer and Nutrition)-InterAct study – including 11,684 incident cases of diabetes. Subjects were surveyed as to dietary intake, energy intake and beverage consumption habits – with sugary drink consumption measured in tiers that included less than one glass monthly, one to four glasses monthly, more than one to six glasses weekly, and one or more glasses daily. The researchers observed that soft drink consumption was linked with diabetes incidence: one or more glasses (12 ounces [354 mL]) daily of soft drink associated with a 58% increased risk of diabetes as compared with those who consumed the lowest levels of soft drinks. The study authors submit that: “This study corroborates the association between increased incidence of type 2 diabetes and high consumption of sugar-sweetened soft drinks.”
Comments Dr. Klatz: “An international panel of researchers reports that a can of soda a day may markedly increase a person’s risk of type-2 diabetes, reaffirming previous findings of data collected on US subjects that suggests a link between sugary drink consumption and 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.
