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 20,000 physician and scientist members from 90 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, A4M president, and Dr. Robert Goldman, A4M chairman, physician co-founders of the anti-aging medical movement, distill these headlines and provide their commentary
Green Tea Improves Heart Cell Function
Charalambos Vlachopoulos, from Athens Medical School, Hippokration Hospital in Greece, and colleagues conducted a study involving 14 healthy men and women (average age 30 years) and found that regular consumption of green tea improved the function of the heartâ€™s endothelial cells (cells lining the walls of blood vessels). Green team consumed on three occasions at a dose of 6 grams, increased the flow-mediated dilation (FMD), a measure of the blood vesselâ€™s ability to relax, by 3.9 percent within 30 minutes after consumption of the beverage. Concludes the team: â€œGreen tea consumption has an acute beneficial effect on endothelial function, assessed with FMD of the brachial artery, in healthy individuals. This may be involved in the beneficial effect of tea on cardiovascular risk.
Dr Klatz remarks: Previous studies have associated tea consumption with reduced cardiovascular disease and death, and other studies have associated a protective role for green tea against certain kinds of cancers as well as Alzheimerâ€™s Disease. This studyâ€™s findings have important clinical implications, as it suggests a significant potential interventive role for green tea in combating the number-one cause of death worldwide.
Minerals Combat High Blood Pressure
A study by Mark C. Houston, MD, reports that an increased intake in minerals such as potassium, and possibly magnesium and calcium by dietary means may reduce the risk of high blood pressure and decrease blood pressure in people with hypertension. A high intake of these minerals in the diet may also reduce the risk of coronary heart disease and stroke. According to the study, if Americans were able to increase their potassium intake, the number of adults with known hypertension with blood pressure levels higher than 140/90 mm Hg might decrease by more than 10 percent and increase life expectancy. Similar studies show that diets high in magnesium (at least 500 to 1,000 mg/d) and calcium (more than 800 mg/d) may also be associated with both a decrease in blood pressure and risk of developing hypertension. Comments Dr. Houston: “If we were to achieve the correct potassium/sodium ratio through dietary means, there would be less hypertension and cardiovascular disease in the population as a whole.”
Dr. Goldman observes: High blood pressure is among the most important public health challenges. More than 70 million Americans, or nearly one in three adults, are estimated to have hypertension, but fewer than 50 percent achieve blood pressure control. Nearly 70 million more adults have high-normal or pre-hypertensive blood pressure levels of 120/80 mm Hg to 130/85 mm Hg, and 90 percent of adults will probably develop hypertension by age 65. Â One of the most important nonpharmacologic means to reduce hypertension is via diet and dietary changes. This study reiterates the value of increased consumption of fruits and vegetables, which are good sources of potassium, magnesium, and calcium, to prevent and treat hypertension, improve blood pressure, and reduce coronary heart disease and stroke.Filed under: Health
