Consumer’s Guide To Dietary Issues For The Prevention Of Dementia
How does diet impact brain function?
A proper diet is essential to good health. Many different kinds of diets are promoted to the public; however, no specific diet is proven to reduce the risk for developing dementia. A heart-healthy diet is recommended for all individuals to reduce risk factors for obesity, hypertension, and to avoid membership in the metabolic club (Click here for more information – 2513.95). Diets that provide sensible amounts of fish, fresh vegetables, and fruits are preferred over diets that include multiple servings of meats and fried foods. Moderate alcohol consumption that is limited to one or two drinks per night is strongly recommended if a person chooses to drink alcohol.
How does vitamin supplementation benefit the adult brain?
Vitamin supplementation may have two beneficial effects for the brain: first, vitamins may protect brain cells against harmful molecules that are normally produced in the brain called “free radicals”. Second, vitamin supplements may reduce damage to blood vessels that are essential proper brain function.
The body produces large quantities of toxic molecules that damage brain cells, called “free radicals’. Free radicals are super-charged molecules that often involve oxygen. Some substances such as Vitamin E or C may reduce the damage produced by free radicals. Nutritional supplements often advertise their ability to “scavenge free radicals” meaning that the supplement will clean out these toxic substances. The scientific evidence does not support the protective role of scavenger molecules such as Vitamin E or C in protecting the brain or reducing the risk of developing dementia. Modest doses of these vitamins are present in most supplements and persons who take a daily vitamin should be assured that they are receiving adequate amounts to meet nutritional guidelines.
Does aluminum or other metals cause Alzheimer’s disease?
Aluminum cookware or aluminum content in drinking water has not been shown to cause Alzheimer’s disease. There is no clear scientific link between aluminum and dementia. Herbal supplements have not been shown to reduce the risk for dementia based on available science.
How do antioxidants impact my risk for dementia?
Food substances that are rich in molecules called “antioxidants” may be beneficial to persons as they grow older. Free radicals are super-charged molecules that can damage brain tissue. Antioxidants can reduce the toxicity of free radicals. Consumers should consider taking a vitamin that contains the recommended daily allowances of Vitamin E and other nutrients called antioxidants which are food stuffs that reduce the level of toxic molecules.
Which vitamins are best at protecting my brain?
The B-Complex vitamins including B6 and B12 may help protect your brain. Folic acid may be beneficial to brain and blood vessels. A standard daily senior vitamin contains the recommended dose of these essential substances. Individuals should discuss vitamin usage with their doctor if they have recently had a heart attack.
