Problem
Colin has been listening to the family discuss his health for the past hour. He sits up and tells the family that he is careful to avoid fat and milk in his diet and the last time he felt this bad was after eating a great meal of spicy Szechuan beef and Hunan duck in hot bean paste. Because nothing in the Thanksgiving meal was fried, he is surprised he had the pain again. Who is most likely to have correctly diagnosed Colin's problem? Explain your reasoning.
