Rumples raises the interesting issue of food poisoning and buffet restaurants are, unless they are really busy and moving the food very quickly, the most likely resto where you will be sickened. Be especially careful with chicken dishes and whole roasted chicken. I know someone who bought a whole BBQ chicken at a local supermarket which resulted in an entire family getting campylobacter food poisoning because the chicken was undercooked. Symptoms in that included simultaneous diarrhea and vomiting and rapid dehydration.
Personally I have gotten food poisoining once and it came from a supermarket prepared antipasto salad of meats, cheeses and vegetables. Symptoms were as noted above.
The only other food product that occasionally caused me problems is a very acidic tomato sauce which gives me acid reflux. Pepto Bismol usually nips the bud on this but Tums X-Strength will also do the job
