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.
Berry Compound Linked to Longevity
Cristina Andres-Lacueva, from the University of Barcelona (Spain), and colleagues analyzed data from 807 men and women, ages 65 and older, enrolled in the Invecchiare in Chianti study. Following the subjects for 12 years, the team measured total urinary polyphenols, and surveyed the subjects as to dietary habits and foods consumed. The researchers observed that the participants consuming the highest levels of dietary polyphenols were at 30% reduced risk of death. Further, those consuming polyphenol-rich foods were at lower risk of chronic diseases. The study authors submit that: “[Total urinary polyphenol] is an independent risk factor for mortality among community-dwelling older adults, suggesting that high dietary intake of polyphenols may be associated with longevity.”
Dr. Klatz observes: “Polyphenols are a type of antioxidant that is found abundantly in blueberries, raspberries, and strawberries. Spanish researchers report that diets rich in such polyphenols may reduce the risk of death.”
Active Leisure Time Improves Metabolic & Cardiovascular Health
Elin Ekblom-Bak, from the Karolinska University Hospital (Sweden), and colleagues analyzed data collected on 4,332 men and women, average age 60 years, residing in Stockholm. At the study’s start, non-exercise physical activity and exercise habits were assessed from a self-administrated questionnaire and cardiovascular health was established through physical examinations and laboratory tests. The participants were followed for an average of 12.5 years for the assessment of cardiovascular disease events and mortality. The team found that at the study’s start, subjects with a high level of non-exercise physical activity of daily life, regardless of regular exercise, achieved more preferable metabolic risk factors, as compared to those with low levels of physical activity. Further, a high non-exercise physical activity of daily life level, regardless of exercising regularly or not, also associated with a lower risk of a first cardiovascular disease event and lower all-cause mortality. The study authors conclude that: “”A generally active daily life was, regardless of exercising regularly or not, associated with cardiovascular health and longevity in older adults.”
Remarks Dr. Goldman: “Previously, a number of studies have suggested a correlation between a sedentary lifestyle and increased risks of metabolic and cardiovascular diseases. This Swedish team finds that older men and women who maintain a high daily level of non-exercise physical activity are better able to maintain healthy metabolic and cardiovascular biomarkers.”
Almonds a Smart Snack for Weight Goals
Richard Mattes, from Purdue University (Indiana, USA), and colleagues studied 137 adult men and women at increased risk for type-2 diabetes. Participants were divided into five groups: a control group that avoided all nuts and seeds, a breakfast meal group and lunch meal group that ate 1.5 ounces of almonds each with their daily breakfast or lunch, and a morning snack group and afternoon snack group that each consumed 1.5 ounces of almonds between their customary meals. All almond snacks were eaten within approximately two hours after their last meal and two hours before their next meal. Participants were not given any other dietary instruction other than to follow their usual eating patterns and physical activity. Participant compliance to consuming almonds was monitored through self-reported dietary intake assessments and fasting vitamin E plasma levels. At the end of the four-week study period, the team found that the study participants eating 1.5 ounces of dry-roasted, lightly salted almonds every day experienced reduced hunger and improved dietary vitamin E and monounsaturated (“good”) fat intake without increasing body weight. The study authors conclude that: “Almonds provide post-ingestive metabolic and appetitive benefits and did not increase the risk for weight gain. This suggests that almonds may be a healthful snack option.”
Comments Dr. Klatz: “Exploring healthy options for snacking, this team reports that consuming 1.5 ounces of dry-roasted almonds daily helps to reduce hunger without increasing body weight.”
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.
