I've seen these criticisms but there never seems to be any actual evidence to back it up. All actual evidence seems to show the opposite. These critics usually just argue that no proteins (enzymes being proteins) could survive the acids in the stomach, but this is clearly not true. For example, some allergies are believed to be caused by proteins passing through intestine walls. These proteins had to pass through the stomach to get to the intestines. Michael
