The Doctors Health Press, a publisher of various natural health newsletters books and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a study that finds evidence that two natural substances -- a mineral and a fatty acid -- can protect against both cancer and Alzheimer's disease.
As reported in the Doctors Health Press e-Bulletin on Friday, March 30, 2012 (, researchers have found that zinc and DHA exert very different -- but beneficial -- effects when it comes to protecting your good health. They prefaced their study by noting that dietary intake of zinc and DHA have health benefits for a number of human diseases.
The Doctors Health Press e-Bulletin reports that after conducting extensive tests, the research team discovered that zinc and DHA affect expression levels of histones H3 and H4 in human neuronal M17 cells. Histones are small proteins that help build DNA. Building healthy DNA, especially in nerve cells, helps keep diseases like cancer and Alzheimer's at bay.
Specifically, zinc helps to reduce the levels of the anti- apoptotic marker Bcl-2, while increasing the apoptotic marker caspase-3 levels. Sounds complicated, but basically, this means that zinc is protecting your cells: it helps the cells that should die do so and prevents substances that halt death in proliferating cells (such as cancer cells) from performing this task. As for DHA, it promotes gene expression (the building of proteins) and neuroprotection, aiding in staving off Alzheimer's.
The Doctors Health Press e-Bulletin also revealed the food sources of zinc include liver, beef, lamb, scallops, sesame seeds, and pumpkin seeds. Food sources of DHA include flaxseeds, salmon, walnuts and sardines.
