Overview
About Sugar
Table sugar is sucrose, half glucose and half fructose.
On its own it is clean on histamine, gluten, oxalate and the other sensitivity triggers, which is why plain sugar is rarely the culprit behind a reaction. Two honest caveats remain: it climbs to a moderate FODMAP load in larger servings because of the fructose half, and as a refined sugar it is pro-inflammatory. The fructose point is the key one: a small spoonful is fine, but a lot of sugar delivers enough free fructose to bother a fructose-sensitive gut.

Watch for
What trips people up
- Moderate FODMAP by volume: small amounts are low FODMAP, but a large dose of sucrose releases enough free fructose to trigger fructose malabsorption symptoms
- Pro-inflammatory as a refined carbohydrate, so heavy intake works against an anti-inflammatory diet even though it is not a chemical trigger
- Pure glucose (dextrose) does not carry the fructose half, so it stays low FODMAP where table sugar rises with the serving size

FAQ
Common questions about Sugar
Is sugar a trigger food?
Not in the sensitivity sense. Plain white sugar carries no histamine, salicylate, gluten or oxalate. It matters more as a moderate FODMAP in large amounts and as a pro-inflammatory refined carbohydrate than as a chemical trigger.
Is table sugar low FODMAP?
In small servings, yes. Sucrose is glucose paired with fructose, and only in larger amounts does the fructose exceed what the gut absorbs, tipping it into a moderate FODMAP load. Keep portions modest and it stays low FODMAP.
What is the difference between sucrose and fructose as triggers?
Sucrose is a balanced glucose and fructose molecule that the body splits and mostly absorbs. Free fructose, the kind concentrated in honey, agave and fruit juice, is the part that overwhelms absorption and causes FODMAP symptoms. That is why a little table sugar behaves better than an equal amount of a high-fructose sweetener.
