A study out of Sweden shows that people with diets rich in vitamin B12 are much less likely to develop Alzheimer’s disease.

Published in the journal Neurology, researchers describe how the risk of Alzheimer’sdropped by 2% for every micromole per liter of vitamin B12 found in the blood.

However, they also found that decreased levels of the amino acid homocysteine, which is also associated with cardiovascular disease and stroke, can also increase the risk of Alzheimer’s. Vitamin B12 can actually lower those homocysteine levels.

According to the source of this story, Medical News Today, study authors conclude that “their study reveals the need for more research into vitamin B12’s role as a marker for identifying individuals at higher risk of developing Alzheimer’s Disease.”

Good food sources of B12 include eggs, sardines, clams, and mackerel.  Learn more about food sources of nutrients.

It has long been known that B12 is essential for a healthy nervous system, with deficiencies leading to permanent damage of nerve cells.  B12 comes from fish, meat, eggs, milk products and processed fortified foods.  People who are on a vegan diet need to make sure they are getting enough B12, since the body stores B12 for a long time and deficiency symptoms may not appear until the problem is serious.
