Latest studies have show that many vegetarians are not getting enough vitamin B12 in their diet. A lack of vitamin B12 can lead to poorer cognitive function including memory loss, and in the long term could attribute to increased risk of dementia and Alzheimers.
The best sources of B12 are from seafood, such as shellfish and fish, as well as eggs and dairy. The studies were carried out in India where a majority of the popular are vegetarians who also do not consume dairy. This certainly seems to be true on the ground – India has over 3.5 million cases of Alzheimers.
Since majority of the Indian population is vegetarian and milk consumption has reduced considerably, they are more prone to early onset of dementia. Those who suffer from lactose intolerance are also at risk.
People who are found to be suffering from memory loss and a deficiency on B12 respond very well to a B12 supplement. Rates of Alzheimers continue to rise across the World as diets continue to become poorer in terms of variety and nutritional value. Remember the advice from the “old wives”: fish makes you clever. They were not wrong.
