Here's something I couldn't find in this forum. It concerns the infamous "Dehli belly"—I have heard of several tales telling that almost every visitor gets Dehli belly; i.e. diarrhea. I read this is because of the oil that is used in cooking. My question: Is this common? Any advice on how to avoid it? I have never visited India before and am thinking about doing the Golden Triangle in January but hesitate if I will become sick from eating the food.
