Light soy milk is a plant-based milk alternative that is made from soybeans. It is called "light" because it is typically lower in fat and calories compared to regular soy milk. Light soy milk is produced by soaking and grinding soybeans, then straining the mixture to extract the liquid. It is a popular dairy-free option for those who are lactose intolerant or following a vegan or vegetarian diet. Light soy milk can be used as a substitute for regular milk in various recipes, such as smoothies, cereal, baking, or enjoyed on its own as a beverage.
