Almost all Soy milk produces contain an ingredient called, Carrageenan.
Carrageenan is one of the worst and one of the most insidiously prevalent harmful additive to our modern diet.
"Milk and other dairy products contain carrageenan, a compound extracted from red seaweed. Carrageenan, which is widely used in the food industry for it's ability to stabilize milk proteins, has been shown to induce ulcerative colitis in laboratory animals."
"Sometimes used as a thickener in many products, such as ice cream and yogurt. Causes stomache upset, deterioration of mammary-gland tissues. In some formulations, is carcinogenic"
I have issues with Soya milk too, unfortunately.
