I just want to say two things:
1. I would not take colostrum due to the possibility that MAP organisms are inherent in the product. People who sell it claim how wonderful it is since it's raw. Hmmm. Also, I personally have much worse symptoms on dairy, whether it is "feeding" MAP or not, I don't know. To me it is not worth the risk.
2. The idea that Crohn's is from a too-strong immune system is outdated. The newest idea is that it is an immune system which is "off-key", not correctly attacking some pathogen, whether it is a mycobacterium or bacterium, instead attacking the host. And the immune system is in some ways weakened by years of making these attacks. If my immune system were so darned strong, I'd never get sick and in fact, I get sick if someone with a cold looks at me!
