Soy milk is a highly processed imitation of real milk, made from dehydrated soybeans, water, and a cocktail of additives. You're not getting the nutrients and benefits of whole soybeans, just a watered-down, chemically-enhanced substitute. This is not food, it's a lab creation.
Why trash
Processed soybeans, added sugar, seed oil emulsifiers, and synthetic vitamins. A far cry from traditional tofu.
Try instead
Almond milk, coconut milk, or whole cow's milk
