Why do we fart? I know this stinks, but let's look at this from a scientific point of view.

Everything we eat or drink gives us gas. In fact, it's normal to fart up to half a gallon (1.9 liters), or about 15 to 20 toots worth of gas each day.

Particularly fragrant flatulence, however, comes from colonies of bacteria shacked up inside our lower intestinal tract. In the process of converting our meals into useful nutrients, these food-munching microbes produce a smelly by-product of hydrogen sulfide gas—the same stench that emanates from rotten eggs.

Just like the rest of us, the bacteria like munching on sugary foods best. The types of sugar naturally present in milk, fruit — and, of course, beans — produce the most farts.
