Lab result delays. Sometimes it can take a while to get back lab results. This can be even harder to deal with when youâre waiting to get test results to see if itâs cancer or if cancer has come back. Itâs scary to find out about a change in blood counts, or a tumor or mass (lump) and not know if itâs cancer.
Another possible cause for diarrhea after eating beef is intolerance, where the body is not able to process the ingredient. This can be brought about by the absence of any one of the digestive acids or enzymes responsible for breaking down meat to its simplest forms.
1 Sulfur containing foods also cause diarrhea. Foods such as garlic, onions, broccoli, cauliflower and cabbage have high amounts of insoluble fiber which is a major cause of gas and diarrhea in the gastrointestinal system.  Legumes are another food that can cause diarrhea. Any type of legume such as beans, soy beans, lima beans or peas will pass through to the small intestine and arrive in the large intestine completely undigested. The undigested legume will cause major flatulence and diarrhea.
