Is chunou sauce (medium thick, japan) low FODMAP?

The standard portion has low ratings for all six FODMAP groups. Fructans change the rating at the larger listed volumes, while the other groups remain low. These results apply to the medium-thick sauce entry; thickness or a similar bottle label does not establish equivalent portions for another sauce style.

Chunou Sauce (Medium Thick, Japan) and IBS: what to know

For someone tracking IBS meals, record the Chunou sauce separately from the crumbed food, cabbage or other accompaniments it is served with. A generous squeeze can be harder to estimate than a measured side portion. The sauce's low rating does not describe the complete meal or predict an individual's response.

Gut-friendly ways to eat chunou sauce (medium thick, japan)

Measure a small amount into a dish before using it as a topping or dip. Spread it across the food with a spoon instead of repeatedly squeezing from the bottle. If mixing it into a glaze, keep track of the original sauce added. Japanese mayonnaise, sometimes served alongside, has its own portion guide.
