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.
Veggies Boost Longevity
Gary E. Fraser, from Loma Linda University (California), and colleagues lead the Adventist Health Study-2, involving 96,000 US and Canadian citizens – including thousands of Seventh-day Adventists (who follow a vegetarian diet). The researchers report that vegans are, on average, 13 kg lighter than meat eaters and five units lighter on the Body Mass Index (BMI) scale, as compared to meat-eaters. As well, the team reveals that vegetarian men live an average of 9.5 years longer, and women an average of 6.1 years longer, than meat-eating counterparts. A potential factor in this longevity is the beneficial effect that the vegetarian diet exerts on blood pressure. Studying a subgroup of 500 subjects of the Adventist Health Study-2 population, the researchers observed that: “vegetarians, especially vegans, do have lower systolic and diastolic BP and less hypertension.”
Dr. Klatz observes: “With lower saturated fats and completely cholesterol-free, abundant dietary fiber, and phytochemicals (including polyphenol antioxidants), a diet rich in vegetables has been shown by a variety of studies to beneficially impact type-2 diabetes and cardiovascular disease, as well as potentially reduce the risks of cancer. Exerting a beneficial effect on blood pressure, a diet rich in vegetables may extend life expectancy by nine years or more.”
Brighten A Bad Day
Jaclyn Maher, from Penn State (Pennsylvania, USA), and colleagues examined the influence of physical activity on satisfaction with life among young adults, ages 18 to 25 years. The first group, consisting of 190 individuals, entered information into a diary every day for eight days. The second group, consisting of 63 individuals, entered information into a secure website every day for 14 days. Both groups were assessed for satisfaction with life, physical activity and self-esteem. The team determined that the amount of physical activity a person undertakes in a particular day directly influences his or her satisfaction with life. In particular, the investigators observed that by exercising just a little more than usual a person can significantly improve his or her satisfaction with life. Reporting that: “[satisfaction with life] was impacted by people’s daily [physical activity],” the study authors conclude that: “These findings extend evidence that [physical activity] is a health behavior with important consequences for daily well-being.”
Remarks Dr. Goldman: “People’s satisfaction with life rates higher on days when they exercise more than usual. Lift your mood by extending your normal exercise routine by just a few minutes.”
Citrus Fruits May Help Lower Men’s Cancer Risk
Susan E. Steck, from the University of South Carolina (South Carolina, USA), and colleagues analyzed data collected on 920 black and 977 white men who were newly diagnosed with prostate cancer, enrolled in the North Carolina–Louisiana Prostate Cancer Project (PCaP), a multidisciplinary study of the social, individual, and tumor-level causes of racial differences in disease aggressiveness. The researchers used the 2011 US Department of Agriculture (USDA) Database for the Flavonoid Content of Selected Foods to help them calculate total flavonoid intake among study subjects. The team observed that men with the highest intake of flavonoids had a 25% lower risk for aggressive prostate cancer, as compared to men with the lowest flavonoid intake; the results did not differ by race. The investigators observed orange and grapefruit juices and tea to be the main contributors to total flavonoid intake for all study participants combined.
Comments Dr. Klatz: “There are over 4,000 flavonoids identified in fruits, vegetables, and beverages (such as tea, coffee, wine, and fruit drinks).Oranges and grapefruits – as well as strawberries and green vegetables – contain flavonoids, potent antioxidant compounds that may lower the risk for aggressive prostate cancer. Experimental studies have suggested that flavonoids may exert an anti-inflammatory action, induce cell death, and impair angiogenesis – all of which may help to lower men’s risks for aggressive prostate cancer. These researchers provide clinical evidence of such an effect.”
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.
