Vitamin A Status At Birth Linked to Long-Term Risk of Cognitive Impairment and Alzheimer’s

Cognitive FunctionA new study has found elderly individuals with low Vitamin A levels may be more at risk of developing Alzheimer’s disease along with lower brain functioning.  Additionally the study found the even a marginal Vitamin A deficiency at birth might affect long-term risk factors.

This new study was made up of findings from mouse models as well as human population data.  The population study revealed that 75% of those with either a significant or even mild Vitamin A deficiency had some cognitive impairment compared to 47% with normal Vitamin A levels that experienced cognitive impairment.  The research on mice confirmed this finding.  Even a mild Vitamin A deficiency during pregnancy or immediately after birth was associated with an increase in the production of amyloid-beta plaques which are associated with Alzheimer’s disease.  Researchers found that mice deprived of Vitamin A performed poorly on standardized tests of memory as well as learning as adults.  Mice that had Vitamin A withheld while they were in the womb but were given a normal diet after they were born had lower performance in general when compared to mice receiving adequate Vitamin A in the womb but were deprived Vitamin A after birth.  It was found that some reversal of decline could be reversed with adequate Vitamin A supplementation.  Researchers concluded that monitoring Vitamin A during infancy as well as during pregnancy and eliminating a prenatal Vitamin A deficiency may aid in halting Alzheimer’s disease development.

Can Vitamin A Put An End to Colon Cancer ? — Nature’s Vitamins

Current research by Swiss scientists at the Ecole Polytechnique Federale de Lausanne suggests Vitamin A has promise in preventing cancer cells from growing. When a patient is undergoing chemotherapy for colon cancer most cancer cells die off, however genetic mutations that may have caused the cancer initially, may survive. These surviving cancer cells block a…
