Some of the soy cheeses have calcium caseinate added to them and people with milk protein allergies will react to this. I have tried Soymage cheddar alternative without any reaction. It says on the front of the package 100% dairy free and casein free. Their address is 2441 Viscount Row Orlando, FL 32809 The cheese tastes o.k. It has a smoky flavour. The texture is pretty good. I paid $3.69 for 8 oz. There is also a cheese made with brazil nuts but I have not tried it yet.
