Why do people fart?

Answer 1

When we eat, we also swallow air. Also, when the food gets digested in the intestines, gas is produced. These gases when passed out through the intestine from the anus into the air are called farts. The gases that make farts smell bad contain ammonia and hydrogen sulfide which are made in the intestine. And eating oily spicy food and drinking lots of soda makes you fart even more
