A thick, milk-like drink made from soy beans and water, often with sweeteners, flavours, vitamins and minerals, or preservatives (though even with none, soy milk lasts a long time compared to cow's milk) added. Very popular in Asia, and gaining popularity in North America, mostly among vegetarians and vegans, but also with people who are lactose intolerant, have a milk allergy, or who have ulcers or stomach problems and can't digest animal milk. Soy milk has a much richer taste and feel than cow's milk. My favourite brand is VitaSoy. Yum!
