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.
Seven Servings of Fruit and Veggies Promote Happiness
David G. Blanchflower, from the University of Warwick (United Kingdom), and colleagues completed a review of cross-sectional data involving 80,000 Britons who were measured by standardized assessments to ascertain life satisfaction, happiness, nervousness, etc., and surveyed for the daily portions of fruits and vegetables consumed. The researchers found that happiness and mental health rise in an approximately dose-response way with the number of daily portions of fruit and vegetables. The researchers find that “well-being peaks at approximately 7 portions per day,” thus leading them to submit that: “Our findings are consistent with the need for high levels of fruit-and-vegetable consumption for mental health and not merely for physical health.”
Dr. Klatz observes: “The fast pace of today’s 24/7 lifestyle leaves many people neglecting to follow the “Five a Day” recommendation by most developed nations that aim at improving cardiovascular health and reducing cancer risk. Economists and public health researchers from the University of Warwick (UK) report that happiness and mental health are highest among people who eat seven portions of fruit and vegetables a day.”
Exercise Intensity Trumps Duration to Combat Metabolic Syndrome
Eva Prescott, from Bispebjerg University (Denmark), and colleagues conducted a study that included both cross-sectional and longitudinal analyses, using data from the Copenhagen City Heart Study. For the cross-sectional analysis, the researchers included 10,135 subjects evaluated between 1991 and 1994, while the longitudinal analysis included 3,992 subjects seen between 2001 and 2003. The team observed that brisk walking halved the risk that metabolic syndrome would develop over a 10-year period. Leisurely walking, even for more than an hour each day, had no preventive effects. In the longitudinal analysis, the team found that both brisk walking and jogging were associated with an adjusted lower risk for developing metabolic syndrome, as was an overall high level of physical activity. Citing the factor that higher intensity exercise boosts cardiorespiratory fitness, the study authors conclude that: “Our results confirm the role of physical activity in reducing [metabolic syndrome] risk and suggest that intensity more than volume of physical activity is important.”
Remarks Dr. Goldman: “Characterized by central obesity, hypertension, and adverse glucose and insulin metabolism, Metabolic Syndrome is a condition associated with increased risk of type-2 diabetes and cardiovascular disease. This study finds that a regular exercise program that focuses on intensity of activity, rather than duration, may significantly reduce the risk of markers implicated in diabetes and cardiovascular disease.”
Curry Compound Improves Cardiovascular Markers
Robert A DiSilvestro, from Ohio State University (Ohio, USA), and colleagues enrolled 19 healthy men and women, ages 40 to 60 years, in a four-week long study. Subjects received a supplement containing 80 mg curcumin, daily; an age-matched group of 19 other subjects were given placebo and served as controls. The researchers found that curcumin supplementation significantly lowered plasma triglyceride levels, lowered salivary amylase while raised salivary radical scavenging capacities, raised plasma catalase activities, lowered plasma soluble intercellular adhesion molecule levels, and increased plasma nitric oxide. The study authors conclude that: Collectively, these results demonstrate that a low dose of a curcumin-lipid preparation can produce a variety of potentially health promoting effects in healthy middle aged people.”
Comments Dr. Klatz: “Emerging evidence, including an extensive review by the European Food Safety Authority, suggests a wide range of health effects of curcumin, the pigment that gives the curry spice turmeric its yellow color. These researchers add to this body of science, reporting that daily supplements of curcumin help to lower cholesterol levels and markers of inflammation.”
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.
