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.
Gender Differences in Keys to Longevity
Mark L. Wahlqvist, from Monash University (Australia), and colleagues investigated the ways that diet contributed to the relationship between sleep quality and mortality, among a group of 1,865 men and women, ages 65 years and older, enrolled in the Nutrition and Health Survey in Taiwan. The researchers observed that sleep played a more important role in men’s mortality than women’s. Among women, those who ate a varied diet that included foods rich in vitamin B6 could still live long lives despite poor sleep habits. Observing that: “Sleep quality played a more important role in mortality for men than for women,” the study authors write that: “In women, [Vitamin B6 levels] predicts mortality more than sleep does.”
Dr. Klatz observes: “While quality sleep and a healthy diet are basic tenets of the anti-aging lifestyle, Australian researchers report that the extent to which these factors contribute to an extended lifespan may differ between men and women.”
HIT to Set Healthy Food Choices
Daniel Crabtree, from the University of Aberdeen (United Kingdom), and colleagues enrolled 15 lean healthy men, average age 22.5 years with an average BMI of 24.2 kg/m2, in a study involving two 60-minute trials: exercise (70% maximum aerobic capacity) and rest, in a counterbalanced order. After each trial, the researchers conducted fMRI during which the subjects viewed images of high- and low-calorie foods. The team found that the insula – the area of the brain that is involved in the anticipation and perception of foods – was less activated during the exercise-phase of the trial. The study authors observe that: “Exercise increases neural responses in reward-related regions of the brain in response to images of low-calorie foods and suppresses activation during the viewing of high-calorie foods.”
Remarks Dr. Goldman: “An exercise program that is performed with a high level of effort, for a brief yet intense period, in an aim to stimulate the body to produce an increase in muscle strength and size, high intensity training (HIT) appears to suppress cravings for less healthy foods, reports this UK-based team.”
Yogurt May Reduce Diabetes Risk
Nita Forouhi, from the University of Cambridge (United Kingdom), and colleagues assessed daily dietary habits among 4,000 men and women, including 892 participants with incident diabetes, for 11 years. Total dairy intake (g/day) was estimated and categorized into high-fat (?3.9%) and low-fat (<3.9% fat) dairy, and by subtype into yogurt, cheese and milk. The data revealed that low-fat dairy intake was inversely associated with diabetes, after adjusting for confounding factors. Further, the team found an inverse association between diabetes and low-fat fermented dairy product intake – and, specifically with yoghurt intake. Writing that” Greater low-fat fermented dairy product intake, largely driven by yoghurt intake,” the study authors submit that: “These findings suggest that the consumption of specific dairy types may be beneficial for the prevention of diabetes, highlighting the importance of food group subtypes for public health messages.”
Comments Dr. Klatz: “Milk, cheeses, yogurt, and other dairy products serve as an important dietary source of proteins, vitamins and minerals. UK scientists find that vonsuming yogurt may cut a person’s risks of Type-2 diabetes by 28%.”
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.
