Diet options are still a popular trend throughout most of the world. We often reach for a diet soda in an effort to cut out extra (usually unwanted) calories from our diet. For most of us, this is no problem. Low-calorie sweeteners found in “diet” food products are used as an alternative to regular higher-calorie sugars that our bodies break down and absorb.

Normally, low-calorie sweeteners pose no risk to us (unless consuming in huge amounts) but some contain FODMAPs which can be troublesome for individuals with GI conditions. But for some people, high FODMAP sweeteners could be aggravating GI conditions and triggering unpleasant symptoms.

Low Calorie, High FODMAP Sweeteners

Some low-calorie sweeteners are actually high-FODMAP foods. Low-Calorie, high FODMAP sweeteners include polyols.


Polyols are also known as sugar alcohols. They contain about half the calories of regular table sugar. Popular polyols are,

    • Isomalt 
    • Mannitol 
    • Sorbitol 
    • Xylitol

Polyols can be naturally found in many fruits and vegetables including, blackberries, strawberries, apples, avocados and peaches. However, they are also commonly added to other foods and beverages and can be found in,

    • Sugar-free mints
    • Chewing gum
    • Sugar-free chocolates

High Calorie, High FODMAP Sweeteners


Some people may be able to eat honey in small amounts (think 1 teaspoon or 1/2 tablespoon or less) without experiencing symptoms. However, other people may not tolerate the sweetener at all.

High-Fructose Corn Syrup

I think this one is fairly explanatory, but high-fructose corn syrup is known to be both high calorie and high FODMAP. High-fructose corn syrup is found in many processed foods and flavourings. It’s commonly found in ingredients used to make cocktails.

Agave Nectar 

Agave nectar (or syrup) is sweeter than honey, but it is also high-calorie and high-FODMAP. 


Molasses is another high FODMAP sweetener that some people may be able to consume in small amounts without experiencing unpleasant symptoms. 

Golden Syrup

This is another syrup that may be IBS friendly in small quantities of 1 teaspoon or less. However, large amounts of golden syrup can trigger IBS signs and symptoms. 

Low Calorie, Low FODMAP Sweeteners
