Vitamin B-12 Needed to Prevent Alzheimers

Posted Feb 15 2011 10:40pm

According to recent research, people who consume foods rich in Vitamin B-12 (such as fish, poultry, meat and eggs) may be at lower risk for developing Alzheimer’s disease. Researchers in Finland have found a link between B-12 consumption, homocysteine levels and Alzheimer’s , the age-related dementia experienced by many older adults. What’s so significant about this finding is that B-12 deficiency is also more common in older adults, as the ability to absorb the nutrient declines with aging. It’s also potentially an argument against veganism for long-term cognitive health , as the only natural sources of Vitamin B-12 come from animal foods.

In the Finish study, blood samples were taken from more than 271 older adults who showed no signs of dementia. Researchers tested them for levels of vitamin B-12 and homocysteine, an amino acid that has been linked to an increased risk of Alzheimer’s disease. They then followed the subjects for seven years. For every unit increase in the subjects vitamin B-12 levels, their risk of  developing Alzheimer’s dropped by two percent.

So other than obtaining sufficient vitamin B-12 in your diet, what else can you do nutritionally to prevent Alzheimer’s? Eat your vegetables! Vegetable consumption has been linked with a lower incidence of dementia . Also, important for brain health are omega-3 fats, found in abundance in cold water fish –  which coincidentally is also a good source of B-12. Research supports their use in the prevention of Alzheimer’s . Sooo…..anyone for a salmon salad tonight?

Be Well,
