A recent Bloomberg News report details a study published in the Proceedings of the National Academy of Sciences that says “vitamins B6 and B12 combined with folic acid slowed atrophy of gray matter in brain areas affected by Alzheimer’s disease.” The study tracked 156 people ages 70 and older and “found that the amount of gray matter declined 5.2 percent in those taking a placebo, compared with 0.6 percent in those who took the vitamin cocktail [of B vitamins].” (I feel sorry for those in the placebo group!)
The article also reported that dementia drugs like Aricept may ease symptoms but they don’t slow or cure the disease. That was certainly the case with my mother. In fact, she suffered some of the many possible side effects of the dementia drugs. I, personally, would rather supplement my diet with vitamins than take my chances with those drugs.
Check out this list for foods that contain B vitamins (and note that they are mostly fresh, unprocessed foods):
