Soy yogurt may have a slight beany soy taste when made directly from freshly prepared soy milk, but this is less pronounced in shop-bought soy yogurt and in soy yogurt made from commercial soy milk.
Soy yogurt contains less fat than yogurt made with whole milk. This amounts to about 2.7% (the same percentage as soy milk), versus 3.5% in dairy yogurt. However, dairy yogurt can be made with 2%, 1%, or fat-free milk, and soy yogurt can also be made from reduced-fat soy milk.[3]
