I understand Statesmetal plates have Aluminum in them so is it safe to eat from since has been shown increase the risk of Alzheimers?

Stainless steel plates do not contain aluminum. They are typically made of iron, chromium, and nickel. Aluminum cookware is generally considered safe for cooking, as the amount of aluminum that leaches into food is typically very small. However, some studies have suggested that exposure to high levels of aluminum may be linked to an increased risk of Alzheimer's disease. For this reason, it is generally recommended to avoid cooking acidic foods (such as tomatoes or citrus fruits) in aluminum cookware, as these foods can cause more aluminum to leach into the food.
