@cazador:
I always give a variaty of food. But what I wanted to say was: "I don't hesitate to give also fish with thiaminase. They catch the fish in the wild also and I supplement the fish with B1."
Also to much thiamine (or vitamine B1 for those that don't know) is quite difficult to give. B1 is a vitamine that is solvable in water, so to much is just given out in the urine. For a human for example you need to eat it practically by the kilo (figurely speaking
) before you'll have to much B1, the body can easily regulate it.
