11 Surprising Foods That Cause Gas

Apples

The teachers’ favorite contains sorbitol, a sugar that's naturally in many fruits. Some people's bodies can’t absorb it properly, which gives them gas and bloating. It can cause diarrhea, especially for children.

Blackberries

Maybe you've enjoyed them fresh, in a juicy cobbler, or dried in teas. Their natural sugar is good for people who want to cut back on sweets, but it's not always good for the gut. If you have a problem digesting sorbitol, you may feel bloated, have belly pain, or have diarrhea, gas, or nausea.

Watermelon

This popular summertime treat is high in fructose, a sugar in fruit. Your body can have trouble digesting it, so you might get gas. It’s rare, but the problem might be in your genes. Doctors call that a "hereditary fructose intolerance." A blood test can tell if you have it.

Artichokes

These veggies have a sugar called fructan that helps set-off gas. If you don’t feel well after you eat them, just stay away from them

Potatoes

Spuds are usually a safe choice for a dinner side item. The starch gives some people gas and bloating, though.

Shiitake Mushrooms

These famous fungi can make you get a little funky. Blame it on mannitol, another natural sugar. It can give you gas -- and if you eat too much of it, it also can act like a mild laxative.

Peas

Love them or hate them, these soft, green veggies have a chain of sugars called galacto-oligosaccharides that feed gut bacteria and cause gas. This can make for a not-so-pleasant post-meal experience.

Coffee

The caffeine in your favorite daily jolt might be making you bolt to the bathroom. Dial back on the java if you feel an urgent need to go or you get  a stomachache after drinking up.

Soda

The bubbly favorite is a gas machine for some folks. Blame the high amounts of added fructose.

Chewing Gum

You gasp air as you chew, which brings gas into your gut. “Sugar-free” types of gum often have sorbitol and xylitol as sugar substitutes. Those give some people gas or even act like a laxative.

Hard Candy

You swallow air when you suck these treats. Plus, some candies are sweetened with xylitol, mannitol, sorbitol, or other sugars that make some people get an upset stomach.
