What is the effect of aluminum on human health?

Aluminum is a naturally occurring element found in the environment, and while it is not considered an essential nutrient for humans, it is also not inherently toxic in small amounts. However, excessive exposure to aluminum can have potential health effects. Some studies suggest a link between aluminum and neurological disorders like Alzheimer's disease, although this is still a subject of debate. Aluminum can also cause digestive issues and bone disorders if ingested in large quantities. It's important to note that the human body can excrete aluminum, so the risk of toxicity is generally low unless there is prolonged exposure to high levels.
