From medicine to the kitchen
Gastro- connects two worlds that seem far apart. In medicine, it talks about the digestive system and its problems. In food culture, it names the art of eating well: the original word meant something like "the laws of the stomach". It even appears in zoology, to name animals that move on a foot under the belly, like snails.

Common mistakes
thinking "gastronomy" only refers to high-end restaurant cooking
"gastronomy" means the art and science of good eating in general — any culinary tradition
"Gastronomy" (gastro- = stomach + Greek "nomos" = law): literally "the laws of the stomach" — the study of food and culture. It covers street food and regional traditions, not just fine dining.
A trick to remember it
Think of gastronomy, the art of good food: gastro- = stomach. gastritis, gastronomy.
