B Vitamins Show Dementia Fighting Potential
Many older adults suffer from vitamin B deficiency and a recent study conducted by researchers at the Karolinska Institute in Stockholm, Sweden found that vitamin B supplements could reduce the risk of dementia. Their findings were published in the October 2010 issue of the journal Neurology.
For the study, researchers recruited 271 Finnish adults aged 65-79 years of age. None of the participants had dementia at the start of the study but after 7 years of follow-up 6% of the participants developed Alzheimer's.
The researchers found that the participants that did not develop dementia had higher blood levels of vitamin B. They also had lower levels of an amino acid called homocysteine, which is linked to dementia, stroke and heart disease. Previous studies have shown that Vitamin B naturally reduces blood levels of this amino acid.
While the researchers were quick to note that further studies are necessary to look into the link between dementia and vitamin B, previous studies have found significant evidence to back the vitamin’s health benefits.
These studies have found that B vitamins play an important role in many essential functions in the human body including nervous system function, red blood cell formation, and hormone function. They have also been shown to reduce the risk of depression, hearing loss and dementia.
Our bodies do not naturally synthesize B vitamins. However, it is easy to increase your intake of these essential vitamins by eating more vitamin B rich foods or taking a quality supplement. Some foods rich in B vitamins include broccoli, asparagus, potatoes, tuna and salmon. Many milk and flour products are also fortified with B vitamins.
