Aluminum is lightweight, heats easily and it’s cheaper than most other materials such as steel, glass, or iron, hence nearly 50% of cookware nowadays is made of it. Numerous studies have already confirmed that when it comes to aluminum, there are no risks, health concerns or causal links that using aluminum cookware can cause health issues, including the claim that it might be a cause of Alzheimer's (which has been refuted since). Most commercial and industrial kitchens use aluminum cookware as it heats fast, has good conductivity and it’s cheap to buy and relatively easy to care for.
In conclusion, if you look after your Magnaware cookware and follow the care instructions, there shouldn’t be any risks of aluminum leaching into your food and posing any danger to your health. You should always discard damaged cookware.
