Tea Contains High Levels Of Aluminium. If I Drink Tea Everyday, Will I Get Alzheimer's Disease?
Several studies attempting to link Alzheimer's disease (AD) with aluminum exposure have been done over the last few years, but the results have been inconclusive and contradictory. There is no definitive evidence that aluminum causes AD, but it appears likely that it may increase the risk of getting it.
However, aluminum is toxic to the body and excessive amounts may increase risk of other diseases, too. It would be wise to monitor your exposure to aluminum and minimize it where possible.
According to the National Institute of Environmental Health Sciences, aluminum is very abundant in our environment and there are many sources of exposure. They estimate that the average intake for most people is about 30-50 mg per day, of which only about 1% is absorbed into the body.
The most common sources are drinking water, foods and some medicines. Processed cheese and cornbread contain small amounts of aluminum, as do some common food additives. Drinking water accounts for about 1/4 of the total daily intake. Some over-the-counter medications, such as antacids and buffered aspirin also contain aluminum.
Leaching from aluminum cookware accounts for only a very small amount of the daily intake, except when cooking highly basic or acidic foods, such as tomato-based foods.
Aluminum drink cans are usually coated with a polymer to prevent leaching, so they are not a major concern.
There is greater concern for inhaled aluminum, such as that in spray antiperspirants. If you choose to use spray products that contain aluminum, be careful to avoid inhaling them.
I have not seen or heard any information regarding the amount of aluminum in tea. I suggest that you check the label for the specific tea you drink to see how much aluminum it contains. Then take into account the amount of aluminum you may be taking in from other sources, and try to avoid excessive total daily intake from all sources.
Neurofibrillary tangles, a protein accumulation found within neurons that has been linked to Alzheimer's disease, contain aluminum. But there is no scientific evidence suggesting that aluminum causes memory problems. However, it is best to try to avoid it.
Alzheimer's is primarily genetic. If it does not run in your family, I wouldn't be too concerned. In addition, many studies done on Green Tea state to preserve your memory.
There have been great breakthroughs in Alzheimer research this year. See http://www.nih.gov/news/health/apr2011/nia-19.htm
New guidelines for AD research have been published due to a greater understanding of the brain changes that result in AD. There is a 76 month window inwhich Semantic Memory begins to show effects and a 75 month window where Working memory is affected. This allows 5-6 years for early detection of Alzheimers.
The new diagnosis measures proteins in the blood and spinal fluid as well as utilizes neuroimaging. I attended a lecture on this (see my recent hub) and heard nothing about aluminum. However, AD is only one of the dementias. There are others, like Vascular dementia that occur due to frequent TIAs, etc. Perhaps one of these dementias is correlated with aluminum?
Alzheimers does link with diabetes. Baseline diabetes doubles the risk of dementia and intranasal insulin has improved memory in mild to moderate Alzheimer patients- according to a patent issued to Dr. Frey.
I did find an article describing the effects of heavy metals like mercury on Alzheimers. Perhaps this is what concerns you. The problem was not with aluminum.
