Good food and good eating are about risk. Every once in a while an oyster, for instance, will make you sick to your stomach. Does this mean you should stop eating oysters? No way. The more exotic the food, the more adventurous the serious eater, the higher the likelihood of later discomfort. I'm not going to deny myself the pleasures of morcilla sausage, or sashimi, or even ropa vieja at the local Cuban joint just because sometimes I feel bad a few hours after I've eaten them.
