A Milk substitute is a product that resembles milk. Milk substitutes have a similar look and taste to milk produced by the mammary glands of a mammal. In milk substitutes many of the ingredients of milk are replaced: A milk substitute may contain fat and proteins obtained from plants. People with a lactose intolerance or a milk allergy often replace milk by a substitute.
The two most common categories of milk substitutes are grain milk and plant milk. The most common grain milk is rice milk, while the most common plant milk is soy milk. Other examples include coconut milk, almond milk, and peanut milk.
