Aluminum is a common element found in the environment, and while it is generally considered safe, there are concerns about its health effects on humans. High levels of aluminum exposure have been linked to neurological disorders, particularly Alzheimer's disease, although the relationship is not definitively proven. Aluminum can also cause bone diseases and anemia, as it can interfere with the absorption of calcium and iron. Long-term exposure to high levels of aluminum may lead to cognitive dysfunction and memory loss. However, the everyday exposure to aluminum from food, water, and medications is considered safe by health authorities, and there is no need for alarm in normal circumstances.
