Soy milk shelf life? Also health benefits/drawbacks?

if you keep it in the fridge then yes it can last long..soymilk is the top most preferred milk for most vegans and many women at the time of their periods because it enriches the blood with lots of plant estrogens to clean up the uterus..soymilk is the ultimate vegetarian source of protein and omega-3 fat acids..it doesnt contain calcium naturally,so always take in moderation,preferably without sugar and try adding some powdered almonds or coffee or green tea to cut off the estrogenic effect..many soymilk varieties i c at d stores out there are added with calcium and are lowfat,so its ok for consumption.
