Longevity News & Review

For The Bali Times

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 22,000 physician and scientist members from 105 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 commentary.

Tea Slashes Stroke Risk

In animal models of stroke, researchers have found consistent evidence of smaller stroke volumes in those animals ingesting tea components or tea extracts. Lenore Arab, from the University of California Los Angeles School of Medicine, and colleagues conducted a meta-analysis of nine studies involving a total of 194,965 study subjects. The team looked at stroke occurrence and tea consumption. They found that people who drank two or more cups daily of tea a day reduced their risk of stroke by 21 percent (as compared to subjects who drank less than one cup a day). Those who drank an additional three cups daily, further reduced stroke risk another 21 percent. Both green and black tea caused these risk reductions; the researchers suggest it may be the polyphenol, epigallocatechin gallate (EGCG), or the amino acid, threanine, present in varying but significant amounts in both kinds of tea, which may be the responsible mechanism of action.

Dr. Klatz observes: Stroke is the third leading cause of death in Europe and the United States, and is a significant cause of long-term disability. This meta-analysis is important in that it identifies a potential role for a simple, low-cost, widely accessible nutritional intervention for stroke prevention.

Increase Vitamin D to Lower Colds and Flu

Recently, a number of studies have suggested a role for vitamin D in innate immunity, including the prevention of respiratory tract infections (RTIs). Adit Ginde, from the University of Colorado, and colleagues analyzed data from the Third National Health and Nutrition Examination Survey, which involved 18,883 adults and adolescents between 1988 and 1994. The team found that people with the lowest average levels of Vitamin D in the blood were about 40-percent more likely to have a recent RTI (as compared to those with the highest Vitamin D blood levels). Further, low Vitamin D levels in people with asthma were associated with a five-time greater risk of RTI; and among COPD patients, RTIs were twice as common among those with Vitamin D deficiency. The researchers suggest that Vitamin D may have a vital role in the production of cathelicidins, a type of protein that is key to immunity.

Remarks Dr. Goldman: For those with healthy respiratory systems, respiratory tract infections causes a few days of mild symptoms and discomfort. However, those individuals with an underlying lung disease are particularly vulnerable to more significant complications from RTIs, posing a burden on healthcare resources. This study is important because it suggests a potential role for Vitamin D supplementation to boost immunity and fight RTIs.

Lifestyle Significantly Influences Risk of Stroke

Four specific health behaviors have now been identified as reducing the risk of stroke in men and women. Phyo K. Myint, from the University of East Anglia, and colleagues studied 20,040 men and women, ages 40 to 79, with no known stroke or myocardial infarction at the study’s start in 1993, following the subjects up to 2007. The team implemented a risk-scoring system to weigh various behaviors and correlate their impact on stroke risk. The researchers found beneficial impact of four specific health behaviors, namely: current non-smoking, not being physically inactive, moderate alcohol intake (1-14 units a week) and having a plasma concentration of vitamin C levels at/above 50 micromol/L (suggesting a daily fruit/vegetable intake of 5 servings a day). All combined, these “four health behaviors combined predict more than a twofold difference in incidence of stroke in men and women,” report the researchers. They conclude that: “These results provide further incentive and support for the notion that small differences in lifestyle an have a substantial potential impact on risk.”

Comments Dr. Klatz: Stroke ranks as the third leading cause of death in the United States. With 780,000 Americans suffering a stroke annually, it is also a leading cause of long-term disability. While stroke death rates have declined over the past few decades, the public health burden of stroke-related disabilities is enormous and will likely increase in coming years as the population ages. The identification of lifestyle choices that may potentially result in risk reductions is paramount.

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.
