A supposed link between aluminum cookware and Alzheimer's Disease made many people afraid to use Guardian Service for cooking. However, the FDA has found no evidence that aluminum cookware emits enough aluminum during use to cause Alzheimer's Disease.
Aluminum reacts to certain foods, including tomato and citrus foods, which can discolor or damage the surface of the cookware and affect the taste of the food. Heavily scratched or pitted aluminum cookware should not be used as it can cause more aluminum than normal to leach into food.
