The term "nondairy" refers to any food or beverage that does not contain dairy products. This can include plant-based alternatives to traditional dairy items such as milk, cheese and yogurt, made from ingredients like soy, almonds, coconuts or oats. Nondairy products are often used by individuals who follow a vegan diet, those with lactose intolerance or other allergies to dairy products, or simply as a healthier alternative to traditional dairy items.
