A few years ago, a British researcher believed that people's exposure to aluminum should be limited. In a new study, this same researcher provides new evidence that aluminum promotes the development of Alzheimer's disease.
Let's first remember that aluminum is a material naturally present in the ground, representing approximately 8.8% of the earth's crust. Thus, it is normal that we find it in food but also in water. The food industry uses it a lot (conservation, dyes, additives), and in particular in the manufacture of packaging and kitchen utensils. In cosmetology, it is found, among other things, in products such as hair dyes and deodorants.
Christopher Exley is a chemist and professor at Keele University (UK). The person concerned had published a study in 2014 in which he advocated limiting the exposure of people to aluminum. According to him, aluminum deposits in the brain would promote the onset of Alzheimer's disease. Visibly very concerned by the subject, the researcher published a new study in the Journal of Alzheimer’s Disease on January 13, 2020.
In this new study, Dr. Exley and his team demonstrated a significant level of aluminum in the brain of patients with dementia. However, the novelty compared to the first study is the demonstration of a co-localization with the beta-amyloid protein. However, this co-localization would promote the onset of Alzheimer's disease. The researchers measured the amount of aluminum in the brain tissue of donors living in Colombia. They had familial Alzheimer's disease, that is to say they shared a specific mutation . However, this mutation causes a high level of beta-amyloid but also an early onset of the disease.
According to the results, 42% of tissues were considered pathologically significant. In addition, fluorescence microscopy has shown that aluminum and beta-amyloid protein are concentrated in senile plaques and sometimes in the cerebral vascular system. In addition, the results were compared with those of a control group of patients without neurological disease.
Finally, Dr. Exley is categorical:in the absence of aluminum, there is no Alzheimer's disease. Moreover, if the body naturally eliminates the excess aluminum, this material remains all the same in the brain, the bones, the nerves but also the liver and the muscles. Remember that aluminum accumulates to an unbearable toxicity threshold for neurons , causing degenerative diseases such as Alzheimer's.
