You should avoid any foods that cause you problems. Foods with gluten and milk are usually top of the list so avoid those if you can.
I've also been looking at a very general and easy protocol for killing a wide range of bacteria, fungus etc. This protocol is currently also being used in Asia, quite successfully, against cancer. This protocol just entails taking iron as a mineral nutrient everyday together with artmesinin which is a concentrated substance that comes from the Wormwood plant(Artemesia annua).
All pathogens love iron voraciously. So when you take the iron the bacteria takes it into it's cell. Then the bacteria absorbs the artemisinin and the artemisinin reacts with the cellular iron to form a dangerous and destructive peroxide. This causes the bacterial cell to implode and completely destroy itself. This reaction does not take place in a healthy human cell because a human cell has many anti-oxidants that help to quench the dangerous effects of peroxide. But pathogens usually do not have any anti-oxidants in their cell which is why the artemisinin/peroxide reaction kills them so quick.
I'm only mentioning this as another alternative for you if Turpentine doesn't help you get rid of Whipples disease.
