Is agave syrup (dark) low FODMAP?

Two FODMAP groups change this syrup's rating: fructose and fructans. Both are low at 5 g, moderate at 7 g and high at 21 g. The listed points do not establish a rating for every amount in between. Light agave and maple syrup have separate entries; colour or sweetness is not a reliable way to transfer portions.

Agave Syrup (Dark) and IBS: what to know

For drinks sweetened with dark agave, record the syrup added to the whole cup, including any top-up. If it is also used in breakfast or a dressing, consider the complete meal rather than the drink alone. A low FODMAP amount does not establish individual IBS tolerance or mean a larger serving will feel the same.

Gut-friendly ways to eat agave syrup (dark)

Weigh the syrup into a small bowl before adding it to a drink or dressing. Mix it thoroughly so that a shared recipe distributes the syrup evenly. For a glaze, calculate the amount that ends up in each serving rather than treating the recipe's whole-batch quantity as one person's portion. Compare rice malt syrup separately if considering a substitute.

Frequently asked questions

How much dark agave is low FODMAP?

The listed low amount is 5 g, described as one teaspoon. Check the weight when trying to match that small reference.

Which FODMAPs are in larger portions of dark agave?

Both fructose and fructans are elevated: moderate at 7 g and high at 21 g.

Does mixing agave into water change the portion?

The drink becomes less concentrated, but it still contains the same amount of syrup. Count the agave in the quantity you drink.

Can dark agave replace maple syrup at the same portion?

Use each syrup's own guide. A culinary substitution does not automatically preserve the same FODMAP portion.
