DON’T FORGET YOUR VITAMINS 

A study giving B vitamins to people with cognitive impairment and a high level of a blood marker for B vitamin status called homocysteine (raised in half of people over age 60) reported almost 9 times less shrinkage in the areas of the brain associated with Alzheimer’s and more than 70% less brain shrinkage overall in those given B vitamins (B6 20mg, folic acid 800mcg and B12 500mcg) versus placebo –  as long as they had adequate blood levels of omega-3 fats found in oily fish. Those with low blood levels of omega-3 didn’t derive benefit from the extra B vitamins. That’s why it is important to make sure you are getting enough B vitamins ad omega-3 fats both from diet and supplements. Two in five people over 61 have insufficient B12 to prevent accelerated brain  shrinkage, often due to poor asbsorption, not dietary deficiency (B12 is in animal products).
