What don't you believe? I don't think you can dispute that bacteria in the gut is important, and I think if they're finding a link between early gut flora and later health, it's not a bad thing.. it just means they can try to improve the health of our children.

I don't think anyone could or should say that replacing a babies entire diet with artificial milk wouldn't have some kind of impact on their health, be it blatently obvious or extremely subtle. If everyone believed that, there'd be no research & studies done, and formula wouldn't ever be improved upon.

If this study can improve formula, then I think it's a good thing.
