Aluminum and Human Health
Introduction
Aluminum, the most abundant metal on Earth, is found in soil, in water and in air. Its chemical and physical properties make it ideal for a wide variety of uses. For example, aluminum and its compounds are often used in food as additives, in drugs (e.g., antacids), in consumer products (e.g., cooking utensils and aluminum foil) and in the treatment of drinking water (e.g., coagulants).
Because aluminum is so pervasive in the environment, to the point of being unavoidable, researchers have long been studying its effects on humans. This research has revealed a link between aluminum intake and neurological dementia in kidney dialysis patients (dialysis encephalopathy). In recent years, the public and the media have become concerned about other possible adverse effects of aluminum on human health, including its role in Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis (Lou Gehrig's disease). In addition, questions have been raised about the potential risks to infants who drink baby formula containing aluminum.
This information bulletin looks at the ways in which we are exposed to aluminum every day, the health risks associated with this exposure, and special issues related to aluminum's presence in food and drinking water. The final section outlines what Health Canada is doing to further our understanding of aluminum and its impact on our lives.
of course, this is a gov site(albeit not as bad as USgov), but it does have some interesting info in it. it also has errors. the fact is, we have increased our exposure to aluminum to new heighths. anyone who has read orlee knows how detrimental this can be. that daily exposure in the gut causes faunal imbalance. even if we can absorb it, that doesnt mean the bacteria in our gut cant. it is the flora and fauna in our gut that contributes the most to our internal environment, or responds the most to our internal environment, whichever pov one prefers.
