While aluminum cookware is generally safe for most people, there are concerns about its potential health effects. Aluminum has been linked to cognitive issues and Alzheimer's disease, although the evidence is not conclusive. For pregnant women and those with health conditions, it is advisable to err on the side of caution. Opt for cookware made from stainless steel, cast iron, or non-stick materials without aluminum. If you must use aluminum cookware, avoid acidic or alkaline foods and ensure the cookware is not scratched, as this can increase aluminum leaching into food.
