For individuals following a lactose-free diet, Soy Sauce can be an excellent seasoning option. It adds umami flavor to dishes without the risk of lactose exposure. Always check the label for any potential additives or flavorings that might contain dairy, especially in flavored or specialty Soy Sauces.
