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 commentaryMore...

More Vitamin D Associated with Fewer Heart-Related Deaths
In a 7.7-year long study involving 3,258 participants (average age 62), Harald Dobnig, from the Medical University of Graz in Austria, and colleagues, found that people with low blood levels of vitamin D are more than twice as likely to die from cardiovascular disease as those with high levels. The researchers found that those subjects with low vitamin D levels also had higher levels of markers of inflammation, such as C-Reactive Protein and Interleukin-6. The team writes that “For the first time, low [vitamin] D levels are associated with increased risk in all-cause and cardiovascular mortality.”

Dr Klatz remarks: This study is the very latest to reaffirm the health benefits of Vitamin D. Previously, separate studies have demonstrated the vitamin’s role in protecting against cancer, improving the health of arteries in the leg, and protecting against heart attacks.

Green Leafy Vegetables Reduce Risk of Diabetes in Women
An increased intake of green leafy vegetables may reduce the risk of women developing type-2 diabetes. Specifically, Lydia A. Bazzano, from the Tulane University School of Public Health and Tropical Medicine in Louisiana, and colleagues, found that for every additional serving consumed, the risk was slashed by 10 percent. The team’s study involved 71.346 female nurses (ages 38 to 63), followed for 18 years. The researchers also found that whole fruit consumption led to an 18-percent reduction in diabetes risk; interestingly, fruit juice consumption was correlated to an increased risk.

Dr. Goldman observes: This week (25 June 2008), the US Centers for Disease Control and Prevention (CDC) announced staggering new statistics on diabetes. The 2007 data show that 24 million Americans, or 8% of the total population of the nation, currently have diabetes. Diabetes has increased disproportionately among the elderly, as 25 percent of Americans age 60+ are now afflicted. The notion that simple dietary choices, such as eating more green leafy vegetables and whole fruits, may significantly affect an individual’s risk of becoming diabetic warrants further investigation.

DHEA Linked to Enhanced Longevity in Men
DHEA-S (dehydroepiandosterone sulfate), secreted by the adrenal glands, is converted by the body to sex hormones (androgens and estrogens). Levels of DHEA-S peak at ages 20s to 30s and then sharply decline. Mika Enomoto, from Kurume University School of Medicine in Japan, and colleagues, studied 940 men and women (ages 21 to 88) for a period of 26 years. Men had higher levels of DHEA-S at the start of the study, and both men and women showed a decline in the hormone levels over time. In women, the researchers did not find any correlation between DHEA-S level and longevity. But for men, low levels of DHEA-S, older age, higher blood pressure, and higher blood sugar levels were significantly associated with shorter lifespan. Among these variables, the team found that high levels of DHEA-S were the most strongly linked to longer life, even after adjusting for the other factors.

Comments Dr. Klatz: DHEA is the most abundant hormone in the human body. It is involved in the manufacture of testosterone, estrogen, progesterone, and corticosterone. DHEA supplementation has been shown in various clinical studies to enhance the immune response against infection. It also has ben reported to be valuable against cancer, coronary artery disease and osteoporosis. DHEA also increases muscle mass and reduces fat mass. In addition, DHEA may help stimulate HGH. For all these reasons, and particularly given the findings of this study, people should consult their anti-aging doctor to determine whether supplementation may be appropriate, given your medical needs and laboratory evaluation.
