Is soy milk as nutritious as cow's milk?

Soy beverages are made by pressing and then grinding cooked soybeans, and their nutrient content is quite different than cow’s milk. Soy milk is lower in protein and riboflavin, has little vitamin A or D naturally, and contains very little calcium. Some soy beverages are fortified with vitamins A and D and riboflavin, and many are fortified with calcium. If kids are drinking soy milk as a substitute for cow’s milk, check the label to make sure the soy milk is fortified with these important nutrients.

If you are lactose intolerant, have a milk protein allergy or are vegan, soy milk is a good non-dairy alternative to cow's milk. While it does have less protein than cow's milk, it has more protein and less sugar than almond milk. In addition, soy milk has no saturated fat.

While cow's milk is the most nutritious, soy milk is a viable alternative for those who cannot drink cow's milk. Whichever alternative you choose, make sure it is fortified with vitamin D.
