Now that's a Dutch Oven.
Full disclosure: my wife got rid of her Le Creuset a couple of decades ago, including the dutch oven. Le Creuset aluminum pots and pans may be hazardous to your health.
The type of Le Creuset we are talking about in Dutch Ovens is cast iron coated with hard porcelain. Leaching aluminum from acidic foods is possible with aluminum foil misused but anodizing makes quality cookware virtually immune to loosing aluminum in cooking and storage.
A non anodized pan used for cooking and then storing tomato sauce overnight leaches an amount of aluminum equivalent to one-four-thousandths of the aluminum in one antacid tablet.
