I've never used coconut milk, but I'd think it'd have to be much better than soy milk. I once queried about rice milk and it was pooh-poohed as starchy. I think soy milk is also starchy, though I haven't tested it. Also, it's my understanding that there are numerous problems with processed soy products. It interferes with your thyroid, blocks absorption of minerals and leaches minerals from the body. That's likely not all. Yucky stuff.

Kind Regards,

Was the government to prescribe to us our medicine and diet, our bodies would be in such keeping as our souls are now. - Thomas Jefferson
