Thank you all for your input. He could probably stand giving up beef. I'd be hard pressed if it were me.
Mad Ivan, is that because of Mad Cow disease? I know a Brit who said he can't give blood because of it!
This has nothing to do with mad cow. I suspect it could have something to do with the hormones fed to dairy cattle. That's where fast food beef comes from.
On the other hand, I just don't know. The sensitivity runs in the family. I just severely limit the amount.
