Aluminum buildup in the body has been a subject of concern, particularly in relation to Alzheimer's disease. While aluminum is naturally present in the environment and is used in various products, including food packaging and cookware, there is no strong scientific evidence to support the claim that aluminum exposure or accumulation causes health problems in humans. The World Health Organization and other health authorities have stated that aluminum intake from food and drinking water is not a significant health risk for the general population. However, it is always recommended to follow good hygiene practices and use cookware that is known to be safe for food preparation to minimize any potential risks.
