Even healthy foods can make you feel unhealthy.

— -- intro: Swapping soda for a pressed juice. Choosing whole-wheat toast over white bread. Grabbing a fiber bar before a tough workout. These seem like smart, healthy choices, right? Then why is it that the fiber bar leaves you with a bloated midsection or the juice (yes, the one with all the fruits and vegetables!) has you feeling sluggish?

If ditching refined, white carbs is the obvious healthy choice, then why is it that whole-wheat toast or linguine can still make us feel heavy? Turns out the reason whole grains are so good for you can also be their potential flaw: fiber. Fiber is an indigestible carbohydrate and quickly increasing your intake or eating too much at once can cause gas, bloating, and belching, explains nutritionist Kristin Kirkpatrick, RD, wellness manager at the Cleveland Clinic. Plus, carbs make you hold on to water, which can contribute to that sudden my-pants-don't-fit feeling after a meal. ??If you're making the switch or upping fiber in your diet, increase it slowly to give your body time to adjust and drink water with any fiber-rich meal to help move digestion along.

It has as few as 30 calories per serving plus the bonus of being low in saturated fat and cholesterol, making it a heart-friendly option. ??But certain brands contain carrageenan, a thickening agent derived from seaweed that has been linked to digestive problems, including inflammatory bowel disease, says Katie Cavuto, RD, a Philadelphia-based nutritionist. The good news is that many brands don't include it, so check the ingredients list and choose one without it if you're experiencing discomfort.

Unfortunately, they're not always easy on the tummy. "These veggies contain an indigestible complex sugar called raffinose that is responsible for producing gas," says Cavuto."On top of that, their soluble fiber doesn't break down until reaching the small intestine which may lead to bloating and an upset stomach." ??This doesn't mean that cruciferous fare should disappear from your plate forever. Steaming is an easy hack that not only breaks down the raffinose to make vegetables easier to digest, it also helps preserve the cancer-kicking compounds, which can be lost when boiling or in the microwave.

There's good reason the "magical fruit" has a song dedicated to its gas-inducing powers: "You can blame starches that can't be digested in the small intestine and end up in the process of bacterial fermentation again in the large intestine," says Kirkpatrick. ??You can still fill up on the fiber and protein-rich legumes without the embarrassing after effects. Rinse canned beans before using and soak the dry variety overnight in water and baking soda to reduce the starches and help ease the post-dinner toot. If you're not a bean fiend, it helps to gradually up consumption over a couple weeks and eat them on the regular so you won't be bothered by gas, she says.

9 Reasons You Should Eat More Beans

The sugar alcohols (like sorbitol, manitol, anything ending in 'ol') are not digestible, says Kirkpatrick. "They cause bacteria to ferment in the intestine, causing gas, discomfort, and bloating."

Chewing on a stick of gum could help keep teeth healthy and has even been shown to boost concentration, but the breath-freshening solution could be the sneaky culprit behind your bloat. "When you're constantly chewing, you're also swallowing air which gets trapped in the intestines and causes gas and that uncomfortable feeling of fullness," says Kirkpatrick. What's more, a 2008 German study revealed that the biggest sugarless gum-chewers—16 to 20 sticks a day—risked not only gas and bloating, but also severe diarrhea and unexpected weight loss, all thanks to sorbitol.

Packed with fruits and vegetables, this magical drink can deliver a ton of nutrients, all in one gulp. But some varieties can be a sneaky sugar trap since they ditch the pulp and skin where all the fiber lies. "Without the fiber, the sugar in fruit and some vegetables causes your blood sugar to spike and fall," explains Kirkpatrick. This sudden dip leaves you sleepy and hungry. ??Check out the labels of store-bought juices and choose those that go easy on the sugar. If you're juicing at home, throw in some veggies like kale or celery to offset the fruits' sugar. Better yet, blend a smoothie. "You'll get in all the nutrients and keep filling fiber," she says.

They're a better snacking alternative than most vending machine options, but if you don't watch the portion size, it can lead to some smelly results. "All fruit has naturally occurring sugars called fructose, but when it's dried, the sugar ends up being more concentrated so there is more in a smaller amount," explains Kirkpatrick. "It also tends to have more fiber, and topping that with the extra sugar leads to more fermentation in the intestine, which can have you feeling gassy." Dried fruit can still be a good-for-you treat and is a yummy add to everything from salads to muffins; just stick to a 1/4 cup serving at a time.
