The effects of aluminum on health: the controversy bounces

After the book came out of Virginia Belle, When aluminum poisoning us.
Virginia Belle is a freelance science journalist and has worked with several national media. She worked in this investigation for two years.

The survey reported the ubiquity of aluminum in our daily lives and its proven toxicity, noted recently that Guy Berthon, former director of research at CNRS "in high doses or regular doses, [l aluminum] is toxic. [...] If a party is naturally eliminated in the urine and the intestinal barrier, another pass through this brick wall that is the small intestine and is found in the blood and the brain. Here, aluminum is deposited, hardened and can not leave. "

Aluminum salts are currently present in the composition of maternal milk industry, additives and food colorings (as baking powder baking powder and aluminum silicate as anti-caking agent in certain cheeses), certain common drugs ( gastric bandages, antacids, vaccine adjuvants and allergen extracts), several cosmetics (deodorants, antiperspirants, sunscreens, skin care products for the face and body, makeup and cleansing), ceramics in orthopedic and dental in tap water.

Today, researchers have shown that when aluminum salts injected directly into the brain of rabbits, dogs and cats, there is a memory deficit of learning, a global slowdown and a loss of curiosity. This reminds some clinical manifestations of Alzheimer's disease. In 2009, a group of researchers at the Hospital Henri-Mondor, Créteil was able to model the path of the aluminum hydroxide in the body, that is to say, its pharmacokinetics, its fate in the body when it is injected into the muscle.
These crystals of aluminum nanoparticles, are much smaller than micron particles, and therefore they are not arrested by the barriers that normally protect us from toxic elements. The migration of these nanoparticles is therefore the blood, spleen, liver, and finally in the brain, in which the metal, neurotoxic out, settles and accumulates.
The conclusion of this research is clear: the aluminum could be responsible for certain neurodegenerative and neuromuscular diseases.
