Is Fructose causing my IBS symptoms?

Fructose may be causing your IBS symptoms, and here’s why! Fructose is one of the most basic breakdown products of sugar, and definitely a word you have heard before. Not being able to absorb large doses of fructose is actually universal (aka it happens to everyone). However, 1 in 3 people are able to absorb very little fructose, or unable to absorb it at all, causing water movement, fermentation in the colon, gas, bloating, abdominal pain, and diarrhea or constipation. Since people with IBS have hypersensitive intestines, even “minor” symptoms may feel exaggerated and painful.

Details, please.

So basically, we are worried about two things, amount and sugar ratio. Have you heard the expression “the poison is in the dose”? Well it is true for most things, including FODMAPs, and especially fructose. Absorption of fructose depends on the amount eaten. It also matters how much fructose there is in the intestine compared to glucose.

You lost me.

No worries, let’s talk about foods that contain fructose and low-FODMAP alternatives to give you a better idea.

Foods High in Fructose	Low-FODMAP Alternatives
Apple	Grapes
Asparagus	Green beans
Cherries	Strawberries, raspberries
Figs, fresh	Rhubarb
Fruit juice (i.e. apple, orange, tropical, berry, fruit punch)	Cranberry juice, tomato juice, water infusers
Honey & Agave syrup	Pure maple syrup, rice malt syrup
Mango	Oranges
Pear	Kiwi fruit
Sugar snap peas	Carrots, cucumber
Sun-dried tomatoes	Roasted cherry/grape tomatoes
Watermelon	Cantaloupe, honeydew melon

What about High-Fructose Corn Syrup (HFCS)?

You get it. HFCS is made through processing of corn starch into a cheaper and high-fructose substitute for table sugar. Different concentrations of HFCS are used in different food products. For example, beverages like pop use HFCS with 55-65% fructose, and processed foods, baking, and cereals use HFCS at 42% fructose.

What should I be looking for?

You can find fructose on a food label in the ingredients list, as:

Dried fruit
Fructose
Fruit juice
Fruit juice concentrate
Fruit sugar
High-Fructose Corn Syrup
Honey or agave syrup

IBS makes eating confusing and frustrating.

It can seem like the healthier you eat, the worse your gut symptoms get! This can cause you to spend more time in the bathroom, and less time in your life.

Imagine…

Taking control of bloating, gas, diarrhea and/or constipation!

Ditching your fear of eating food!

Saying YES to events (and sticking to it)!

No more sick days!

Freedom from gut issues?

It was possible for me and it’s possible for you, too!
