One intestine problem I have noticed is constipation if you have too many meals with dairy products but not enough with at least one green vegetable but no dairy products. Most dairy products are high in calcium. Most green vegetables, especially leaves, are high in magnesium. If you have both at the same meal, your intestines will absorb only the calcium. Magnesium is needed to make your large intestine move properly. Dark chocolate also contains magnesium, but not as much as the darker leaves, such as turnip greens.
