1 sausage (3.5 oz/100 grams) is low in FODMAPs and should be tolerated by most people with IBS
2 sausages (7 oz/200 grams) might be too much and intake should be limited. This amount of German Bratwurst contains moderate amounts of Fructans.
Bratwurst is a type of German sausage made from veal, beef, or most commonly pork. The name is derived from the Old High German Brätwurst, from brät-, finely chopped meat, and Wurst, sausage, although in modern German it is often associated with the verb braten, to pan fry or roast. Beef and veal are usual in halal and kosher bratwurst, which never include pork for religious reasons.
As a pub dish, it is often accompanied by sauerkraut or potato salad and sometimes served with dark, crusty country bread made predominantly from rye flour, less commonly with a Brezel (pretzel). It is a very popular form of fast food in German-speaking countries, often cooked and sold by street vendors from small stands.
