Vitamin B12 could help protect against Alzheimer ’s disease , a new subject area hint .
" Even a relatively modest change in [ vitamin B12 ] can significantly affect the peril " of developingAlzheimer ’s disease , survey researcher Dr. Babak Hooshmand , of the Karolinska Institute in Sweden , told MyHealthNewsDaily .
Beef liver is one of the most vitamin B12-rich foods, with 800 percent of our daily recommended value.
When the eubstance has normal grade of vitamin B12 , it ’s able to forestall the effects of a compound in the blood called homocysteine , which at gamey levels , is associated with Alzheimer ’s disease and solidus , Hooshmand articulate .
Vitamin B12is most commonly found infish , nub and fortified cereals . It ’s also gained popularity over the last few days because of its putative energy - increase effects , but there ’s no evidence that taking postscript increases zip levels in the great unwashed who are n’t deficient in the vitamin , according to the National Institutes of Health .
And eating solid food naturally high-pitched in B12 is a better way to get the vitamin than taking any supplement , deglutition , guesswork or injectant , Hooshmand said .
The survey will be issue tomorrow ( Oct. 19 ) in the diary Neurology .
blood line test and B12
researcher monitored 271 Finnish masses , ages65 to 79 , who did not have dementia . By the conclusion of the seven - year sketch , 17 mass developedAlzheimer ’s disease .
Blood sample distribution were taken from everyone in the study , and research worker supervise their homocysteine and vitamin B12 levels . None of the citizenry in the study took B12 supplement .
The research worker found even a tiny increase in vitamin B12 had a fundamental impact on diminish the risk for Alzheimer ’s disease , Hooshmand said .
The termination held true even after taking years , sex , blood pressure , weight unit and smoking status into business relationship .
Brains and B12
The findings support other inquiry done on the effect of B12 on memory . In 2004 , a study issue in the journal Neuropsychology found , among aged people already at risk of develop Alzheimer ’s disease , those with vitamin B12 deficiencies performed more poorly on memory trial than those with normal B12 stage .
And in a September cogitation in the journal PLoS One , University of Oxford scientists find vitamin B12 supplements slacken the charge per unit of brain shrinkage in sometime grownup with mild cognitive handicap , a precursor to Alzheimer ’s disease .
Hooshmand said his new study would need to be repeated with a larger group of participant before it could affect clinical practice .
field also require to be done to test whether vitamin B12 supplement interventions make a divergence in decreasing the risk of Alzheimer ’s disease , he say .
