How often do you pass gas? What does it smell like? What does it sound like?

The answers to those questions say a lot about your diet and health.

"People who produce excessive amounts of gas and particularly foul-smelling gas -- if you're eating a super-high-fiber diet, that could be part of it," gastroenterologist Dr. Anish Sheth said. "But if it's something that's persistent, and your significant other is noticing it, it could be a problem."

Carbohydrates such as sugars, starches, and fibers produce the most gas, gastroenterologists say, which is why vegans and vegetarians tend to be more flatulent than meat eaters.

"So if a person is eating a lot of beans, vegetables like broccoli, cauliflower or Brussels sprouts, whole wheat or bran, even sodas like fruit drinks with fructose sweetener, they can have more gas," Dr. Gina Sam said.

The foul-smelling odor in flatulence comes from a combination of sulfur compounds, which make up less than 1% of the gas.

Many red meats and proteins contain higher amounts of sulfur, so while vegetarians/vegans may pass more gas, farts from meat eaters may smell much worse.
