Soy milk is a plant-based beverage made from whole soybeans or soy protein isolate. It is created by soaking and grinding the soybeans, then boiling the mixture and filtering out the solids. This process results in a creamy liquid that is often used as a dairy milk alternative. Soy milk is popular among those who are lactose intolerant or follow a vegan diet. Rich in protein, soy milk also contains essential vitamins and minerals, such as calcium and vitamin D, which are often added during processing. It is available in various flavors, including original, vanilla, and chocolate, making it a versatile option for smoothies, cereals, and cooking.
