Actually, if it is a true protein allergy, beef is right on target as is many processed foods which contein milk proteins also. I had a mom who worked with an excellent gastroenterologist to continue breastfeeding her baby and the baby had blood in stools for months. Finally, after totally eliminating all bovine products results were good but it took 6 weeks for all to clear mom's system.
