Eugene D. Weinberg PhD is emeritus professor in biology at Indiana University and long-time authority on iron overload. His recent landmark paper, entitled The Hazards Of Iron Loading, published in the November issue of Metallomics (Volume 2, pages 732–740, 2010), provides authoritative evidence for the predominant role of iron in human aging.
Consider some of the striking facts that Dr. Weinberg presents in his report:
|Enhanced Mortality Associated With Elevated Transferrin Iron Saturation
(transferrin is the iron transport protein)
|Years after first transferrin saturation observation||Mortality %
Transferrin saturation less than 55%
Transferrin saturation more than 55%
Heme iron found in meat is more highly absorbed than non-hem iron found in plant foods. But Dr. Weinberg notes that citrus fruits, as healthy as they are advertised, fail to protect against iron loading apparently because of their high content of ascorbic acid which facilitates absorption of non-heme iron in plant foods. “In contrast, in non-citrus fruits, as well as in tea, coffee and cocoa, numerous polyphenolic compounds bind non-heme iron and strongly limit its absorption,” writes Weinberg. He adds that the intake of grains that contain IP6 phytate, a strong iron chelator (key-lay-tor), causes suppression of non-heme iron loading.
Weinberg summarizes by saying that it is becoming apparent that “life was designed to exist at the very interface of iron deficiency and iron sufficiency.” To read the entire report, click here (registration is required for free viewing). – Copyright 2010 Bill Sardi, ResveratrolNews.com Not for posting on other websites.
