Rice Syrup
Serving sizes
Rice Syrup changes rating with portion size. These are the amounts tested in the literature behind our ratings.
- About 1 tablespoon (30g)
- Larger portions
- Much larger portions
Rice syrup is Low FODMAP at about 1 tablespoon (30g), with Fructans building at larger portions.
- About 1 tablespoon (30g) of rice syrup is low.
- Fructans build with the amount, so larger portions are moderate and much larger portions are high.
Use it as a smooth, pourable sweetener, keeping to about 1 tablespoon (30g) per serve.
Why rice syrup is rated low
Rice syrup is low at about 1 tablespoon (30g). Larger portions move it to moderate and much larger portions to high, as fructans build with a bigger pour. Rice syrup is rice starch broken down into simple sugars, mostly glucose and maltose, which is why it is such a useful smooth, pourable sweetener on this diet. About 1 tablespoon (30g) is roughly the amount that sweetens a bowl of oats or a portion of a glaze. That is a genuine green light for using it as a sweetener, not a licence to treat it as unlimited, and the sweetener is rarely the only thing in the bowl.
What changes your risk
- Serving size About 1 tablespoon (30g) is low, larger portions are moderate and much larger portions are high. The sort of pour that sweetens a bowl of oats, a share of a batch of flapjacks or a marinade sits near the low serve, while a syrup-heavy dessert eaten in one sitting can climb well past it.
- Stacking across the meal A low rating is per serving, not per plate. The granola, fruit and milk the syrup goes onto all carry their own load, and the total of a meal is what tends to cause trouble rather than any single low ingredient.
- What it is blended with Plenty of jars sold as a rice sweetener are cut with other syrups, and a blend containing honey or agave is a different product with a different answer. The ingredients list is the only reliable way to tell, since the front label rarely says so.
- Finished products built on it Rice syrup is a common base for cereal bars, granolas and glazes, and those often carry inulin or chicory root fibre for texture, or onion and garlic powder in the savoury versions. The syrup is fine; the recipe around it is what needs checking.
- Reducing it down Simmering a glaze thickens it by driving off water, which concentrates whatever else is in the pan rather than removing anything. Heat does not break FODMAPs down, so a reduced teriyaki style glaze made with onion and garlic ends up more concentrated in them, not less.
What else works
If rice syrup is not on the shelf, maple syrup and ordinary table sugar both fill the same sweetening role, and rice malt syrup is the same style of rice based sweetener sold under another name. The lookalikes worth avoiding are the ones that sit right beside it in the baking aisle and pour almost identically: honey and agave syrup are both high FODMAP and are not a swap for this, no matter how similar the texture or how natural the marketing. Golden syrup style sweeteners vary by brand, so read the ingredients rather than assuming they behave like rice syrup.
How to keep it low
Look for a jar whose ingredients list reads as rice, water and an enzyme and nothing else, since single ingredient versions are easy to trust and blends are not. The syrup is thick and slow, so standing the jar in warm water for a few minutes makes it pour properly and stops the temptation to keep tipping. Measure it into a spoon or onto a kitchen scale rather than pouring straight from the jar over a bowl, which is the simplest way to keep a serve to about 1 tablespoon (30g). It keeps at room temperature in a sealed jar and crystallises a little in the cold, so the back of a cupboard beats the fridge. Eating out, glazes and dressings built on a rice sweetener are usually seasoned with onion and garlic as well, so ask what else is in the sauce.
Common questions
is rice syrup low fodmap
Yes. Rice syrup is low at about 1 tablespoon (30g). Larger portions are moderate and much larger portions are high, as fructans build.
how much rice syrup can i have
About 1 tablespoon (30g) is the low serve, which is the sort of amount you would use to sweeten a bowl, a share of a batch of baking or a marinade. Larger portions move it to moderate, and much larger portions to high.
can i use rice syrup instead of honey
Yes, and that is one of its best uses, because honey is high FODMAP while rice syrup is low at about 1 tablespoon (30g). Check the label first, since some jars are blends that include honey or agave.
is brown rice syrup the same as rice malt syrup
Those names are used for the same style of rice based sweetener. What matters is the ingredients list: a jar blended with honey or agave is no longer the same answer.

Where this rating comes from
Rice Syrup is rated from published lab measurements of its FODMAP content, using the low, moderate and high cutoffs of Varney et al. (2017).
