Why is High Fructose Corn Syrup Bad for You?


Fructose-sodaA common, but still relatively unknown cause of bad gas and digestive problems is high fructose corn syrup malabsorption.

More and more people are becoming aware of the dangers of high fructose corn syrup to their health, but fewer would know that too much fructose can also lead to bloating, intestinal cramps and excessive flatulence.

Ahead is just what high fructose corn syrup is, why so many people are experiencing fructose malabsorption and a list of both high fructose foods, drinks, sweeteners and fruits and fructose free or low fructose alternatives for better health.

What is 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.

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

It’s a different story however, when we start consuming excessive amounts of HFCS sweetener found in many processed foods, and particularly sugary drinks and sodas.

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

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

By far the biggest source of high fructose corn syrup in most American diets through are sugary beverages like soda, ‘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 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 health problems with this dangerous drink).

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 high fructose corn syrup laden sodas and fruit juices without obvious, or at least immediate problems. While others will suffer bloating, intestinal cramps and excessive gas when they drink much lesser amounts of these products.

Studies show that approximately 30% of healthy adults can’t process more than 50 grams of fructose without experiencing gastrointestinal distress and up to 70% of patients with irritable bowel syndrome have fructose intolerance.

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

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

Symptoms of fructose and HFCS malabsorption include bloating, abdominal pain and cramps, increased intestinal noises, IBS, flatulence and diarrhea.

Despite all of this, fructose malabsorption is one of the simplest causes of bloating and excessive flatulence to fix. You just need to have less of it. Quitting HFCS laden sodas would be a great start.

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

High Fructose Foods and Drinks List

Use this list of high fructose sweeteners, drinks, processed foods and fruits to see where the most likely sources of fructose are in your diet and which ones you can easily limit or avoid.

Aside from otherwise healthy fruit, any of the others that you can remove or greatly reduce can not only help digestive problems, they’ll also likely improve both your waistline and your overall health.

Of this list, the fruits are by far the healthiest source of fructose, but it’s still a good idea to limit those for a while too if you’re experiencing digestive issues.

High fructose corn syrup has no place in a healthy diet. It is so bad for you it will not only increase your risk of diabetes, heart disease and liver failure, it’s also one of the most effective fatteners of the human body ever invented.

Replacing soda with healthier alternatives and cutting back on sugary snacks is a great start, but other foods you may have thought of as healthy, like canned fruit or apple juice, are also important to ditch. This is not just for bloating and flatulence, but for your long term health and wellbeing.

Next is a list of fructose free or low fructose foods, drinks and sweeteners you can use as an alternative to the high fructose products above.

There’s also a list of low fructose fruits which are the best choices to eat if you have fructose malabsorption that is leading to digestive problems like bloating, abdominal cramps and excessive flatulence.

Better Health Without High Fructose Corn Syrup

Cutting back on the amount of fructose you consume isn’t just good for reducing gastrointestinal problems like bloating and flatulence either. High fructose corn syrup is a highly fattening substance, metabolized by your liver into triglycerides and strongly linked to an increased risk of many life threatening diseases.

If you drink sugary sodas or commercial fruit juices these will usually be the biggest sources of fructose in your diet. Swapping out these for healthier alternatives is one of the best things you can do for your health.

If you suspect you may have fructose malabsorption, then compare this list of high fructose foods and low fructose alternatives and see where you can make some changes. Your body will thank you for it in more ways than one.

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
