Zinc supplements maintain cognitive function in Alzheimer's disease
Thursday Jly 17, 2014 (foodconsumer.org) -- Doctors say there is no cure for Alzheimer's disease and researchers say nearly 100% of experimental drugs do not show any efficacy against the disease.
Environmental risk factors are key to the development of Alzheimer's disease. And it has been known that inorganic copper in drinking water and supplements along with a high fat diet increases risk of Alzheimer's disease. In patients with Alzheimer's disease, serum copper is found high.
A new study now suggests that taking zinc supplements may help overcome the potential risk of the disease increased by inorganic copper from drinking water. In fact, patients with Alzheimer's disease are often found zinc deficient.
(Check and see if copper is still present in your dietary supplements. Throw it away immediately if your dietary supplements contain the useless yet toxic metal. Copper just like fluoride has no nutritional value and should never be present in supplements.)
In this small trial that lasted six months, patients aged 70 or older with Alzheimer's disease and taking zinc supplements maintained cognition or prevented cognitive decline.
Alzheimer's patients who took zinc supplements were also found to lower their serum copper levels.
In conclusion, either increased serum zinc or decreased serum copper or both may help relieve the severity of Alzheimer's disease.
Comment: Zinc oxide should be not present in your dietary supplements. As nanoparticles, zinc oxide can be toxic and cause DNA damage. (David Liu)
