In patients with cholecystitis, it is usually clinically necessary to avoid eating meat because cholecystitis is usually caused by acute or chronic cholecystitis due to gallbladder stones or polyps. The gallbladder itself is an organ of the body whose main function is to store and concentrate the bile secreted by the liver, and to participate in the digestion of food by contracting the gallbladder after eating and secreting the stored bile into the intestine. Bile mainly digests the fat in food, and theoretically all meat contains more or less fat. For patients with acute or chronic cholecystitis, eating meat, i.e. food containing fat, may lead to aggravation or even triggering of the symptoms of cholecystitis, so patients with cholecystitis, whether acute or chronic, usually try not to eat meat, or just a small amount of pure lean meat, i.e. meat that does not contain fat.
