Milk substitutes are often derived from either rice or soy. Products like Rice Dream® and Silk® are readily available right next to the usual dairy offerings of milk. These products come in generic brands as well, which many find comparable to name brands. Some products use a milk substitute to replace dairy ingredients like cream. One can find ice creams made by both Rice Dream® and Silk® next to traditional milk or cream frozen confections. Both rice and soymilk are comparable to milk in protein, but lower in saturated fats. Rice milk has a lower protein count than both dairy and soymilk. Some people have difficulty digesting soy and may prefer a milk substitute made from rice. One can also make one’s own milk substitute from soy or rice. http://www.wisegeek.com/what-are-some-milk-substitutes.htm
