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 optimise the human aging process. Dr Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, and Dr Ronald Klatz, M.D., D.O., A4M President, physician co-founders of the anti-aging medical movement, distil these headlines and provide their commentary.
Good for the Heart, Guard Against Cancer
As an American Heart Association Strategic 2020 Goal, “ideal” cardiovascular health is one of elements that aim to improve Americans’ heart health by 20 percent and reduce deaths from heart disease and stroke by 20 percent. Laura J Rasmussen-Torvik, from Northwestern University, and colleagues followed more than 13,000 healthy individuals for 13 years, measuring seven “metrics” of heart health at the start and tracking any cancer that developed. Those seven factors are: not smoking, normal BMI (a calculation based on weight and height), physical activity, healthy diet and safe cholesterol, blood pressure and fasting blood glucose levels. Between 1987 and 2006, the participants developed more than 1,800 new cancers, namely prostate, breast, lung and colon. But the more “ideal” factors people had the less likely they were to develop cancer. Compared to people who had none of the seven factors, having just one reduced the risk of cancer by 20 percent. Three factors lowered the risk of cancer by 22 percent, and five to seven pushed the risk down 38 percent. The study authors conclude that: “Ideal cardiovascular health metrics are also collectively associated with lower cancer incidence.”
Dr Klatz observes: Advancing the notion that attaining ideal cardiovascular health may help to stave off cancer, these researchers underscore the life-extending role of key markers that not only define a healthy lifestyle – but an anti-aging one as well.
Regular Exercise Promotes Quality Sleep
Among adults in the United States, an estimated 35 to 40 percent of the population has problems with falling asleep or with daytime sleepiness. Paul Loprinzi, from Bellarmine University, and colleagues studied a nationally representative sample of more than 2,600 men and women, ages 18-85 years, adding evidence to mounting research showing the importance of exercise to a number of health factors. Specifically, the team found that 150 minutes of moderate to vigorous activity a week, which is the national guideline, provided a 65-percent improvement in sleep quality. People also said they felt less sleepy during the day compared to those with less physical activity. Concluding that: “Objectively-measured physical activity was associated with several self-reported sleeping-related parameters,” the study authors note that: “Those who were more active fell asleep quicker.”
Remarks Dr Goldman: Finding that people who get at least 150 minutes of exercise a week sleep significantly better and feel more alert during the day, this team adds to the ever-growing body of scientific evidence that supports the life-affirming role of routine physical activity.
Is Soup Toxic to Your Health?
Bisphenol A (BPA) is a plasticiser that is regarded as an endocrine disruptor that may be linked to cardiovascular disease, diabetes and liver abnormalities. Commonly used in food can linings, Karin B. Michels, from Harvard School of Public Health, and colleagues assessed the urinary bisphenol A (BPA) levels of 75 healthy men and women, ages 18 years and older, who consumed homemade soup for five consecutive days, and then ate canned soup for another five days in a row. Urinary levels of BPA averaged 1.1 mcg/L during the homemade soup segment but reached 20.8 mcg/L during the canned soup segment. Observing that: “The effect of such intermittent elevations in urinary BPA concentrations is unknown,” the team urges that: “Even if not sustained, [it] may be important, especially in light of available or proposed alternatives to [BPA-containing] epoxy resin linings for most canned goods.”
Comments Dr Klatz: Canned soups raise excreted bisphenol A levels, a compound regarded as an endocrine disruptor with potential risks to human health. Whenever possible, avoid canned and opt for freshly homemade – enabling you to control the ingredients.
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.
