Bad habit #2: You cook or store acidic food in reactive pans
Aluminum is often used in cookware because it's a great conductor of heat, but isn’t so good in your food. How would it get there? Cooking or storing something acidic in reactive pans, such as aluminum and cast-iron, can eat away at the metal and impart an off color and/or off flavor in your food. Use a nonreactive pan (stainless-steel, enamel-coated or glass) when cooking with acidic foods like lemon juice or tomatoes to prevent the food from reacting with the pan.
