Fructose Malabsorption: Why HFCS Causes Bloating and Gas


A common, but still relatively unknown cause of an upset stomach, bad gas and other digestive issues is fructose malabsorption in the gastrointestinal tract.

More and more people are becoming aware of how unhealthy high fructose corn syrup is. Far less know that too much of this fruit sugar can also lead to bloating, intestinal cramps, excessive gas and even diarrhea.

Ahead is just what fructose is and why it is malabsorbed for so many people. You’ll also find a list of high fructose foods and drinks, as well as HFCS-free alternatives for improved gut health and a better body.

What Foods and Drinks Contain Fructose and HFCS?

Many fruits and most sweeteners contain high levels of fructose. Unlike glucose, which is easily used throughout your body as energy, fructose is primarily metabolized in your liver.

In small amounts this isn’t a problem. Unfortunately, with high fructose corn syrup now such a common ingredient in processed foods, many people are getting far too much of it for their liver to deal with effectively.

Fructose-soda

Also known as HFCS, this highly fattening ingredient, strongly linked to an increased risk of serious disease, has been added to a numerous processed foods. So much so that it’s quite a challenge to find a product without it in the middle aisles of most supermarkets.

Fructose is sometimes called fruit sugar and fruits are the traditional source of it. Your liver can usually comfortably deal with the amount of it in the occasional apple, pear or kiwi fruit.

It’s a different story however, when you start consuming excessive amounts of HFCS sweetener found in many processed foods, and particularly sugary drinks and sodas. These high levels of high fructose corn syrup can easily cause an upset stomach, painful cramps and even diarrhea in sensitive people.

Common table sugar is a big source of fructose, but in recent decades it has been eclipsed by the huge increase in corn syrup consumption.

By far the biggest source of HFCS in most American diets though are sugary beverages like sodas, ‘sport’ drinks and commercial fruit juices.

So called sport drinks and packaged fruit juices often contain more than 50 grams of fructose per 33 oz bottle.

Even worse, a large 34 oz bottle of the most popular soda pop contains 108 grams of total sugars, or 27 teaspoons, of which up to 65% of these are fructose (and that’s just the start of the problems with acidic soda).

What Causes HFCS Malabsorption and Why is It so Bad for You?

All of us will experience an inability to metabolize fructose at high enough levels, though just where this level is appears to vary considerably from person to person.

Some people can guzzle HFCS laden sodas and fruit juices without obvious, or at least immediate problems. While others will suffer bloating, an upset stomach, intestinal cramps and excessive gas when they drink much lesser amounts of these products.

Studies show that approximately 37% of healthy adults can’t process more than 50 grams of fructose without experiencing gastrointestinal distress and symptoms like diarrhea. Furthermore, up to 70% of patients with irritable bowel syndrome have a clear intolerance to fruit sugar.

Food for Bad Bacteria

When you give your body too much HFCS, and other forms of fructose, for it to absorb, it has to go somewhere. That somewhere is down to your lower intestine for bacterial break down.

Fruit sugar is a favorite food for bad bacteria in the colon and they proliferate and produce large amounts of gas in the presence of excess corn syrup in particular.

Symptoms of HFCS malabsorption include bloating, abdominal pain and cramps, increased intestinal noises, IBS, excessive flatulence and diarrhea. Soda consumption can also lead to an overgrowth of bad bacteria.

Despite all of this, fructose malabsorption is one of the simplest causes of bloating and bad gas to fix. You just need to have less of it. Quitting soda saturated with corn syrup would be a great start.

Unlike indigestible oligosaccharides, found in beans that make you fart and gas producing vegetables, fructose can be processed by your body. Just not in the excessive amounts too many of us are regularly consuming.

Had some grape jelly on a thick bagel recently, filled as I later noticed, with HFCS. About 2 hours later I began having painful cramping on my left side. It slowly proceeded to my right side before I was able to sleep about 10 hours later.I took a laxative and later the next morning the intensity of the cramps had subsided and were less frequent. I drank alot of water the second day and by the end of the day I was fine…so roughly 30-32 hrs of discomfort…Needless to say, threw the culprit away
