‘Want a Healthy Brain?’ – http://www.laurelonhealthfood.com, 09/09/08
The University of Oxford concluded that consuming more vitamin B12 in our diets may prevent brain shrinkage and memory loss later in life. In a study of 107 people who were 61-87 year olds, those with the highest B12 levels in their blood were six times less likely to have brain shrinkage than those with lower levels of B12.
‘Study author Anna Vogiatzoglou, M.Sc. said, “this study suggests that simply adjusting our diets to get more vitamin B12 through eating meat, fish, fortified cereals, or milk may be something we can easily accomplish to prevent brain shrinkage and so perhaps save our memory.” The Oxford study did not measure whether B12 in supplement form would make any difference in brain shrinkage.’
Unlike the vitamin B6 post earlier, the study source is from the U.K, and advises we can obtain the vitamin through our food, not vitamin supplements. Perhaps the researchers were aware of the vitamin supplement debate earlier in the year, so did not mention vitamin tablets as a source of B12.
