Couscous is durum wheat semolina and contains gluten. Rice and corn versions are the gluten-free swap.

HalalYes
KosherYes
KetoNo

Semolina is a starchy wheat product.

Low-FODMAPNo

Wheat is high in fructans, so couscous is one of the first grains to cut.

The short answer
Couscous is rolled durum wheat semolina, so it is wheat in another shape and it contains gluten. It cooks in minutes and it is high in fructans, which puts it near the top of the low-FODMAP cut list.

🇨🇦 Health CanadaNot evaluated as an additive
CaliforniaNo extra rules

Couscous is a food with no E-number. It falls under the standard for durum wheat semolina in the United States and under the cereal rules in the EU, and it carries the wheat allergen declaration that those rules require.

Daily limit: Experts haven’t set a number because normal food amounts are far below any level of concern.

What is it?

The manufacturing is old North African technique: semolina is mixed with water, worked into small lumps, rolled into beads and steamed. The result is a pasta shape made from wheat with a protein content close to pasta and a cooking time of about five minutes. Wholewheat couscous is milled from the whole durum kernel, so it keeps the bran and the germ and has more fiber and a deeper flavor.

Where it comes from: Small balls of durum wheat semolina rolled into tiny beads. The beads are steamed or soaked so they swell and cook quickly, and the whole thing is closer to a pasta than to a grain.

Health & gut impact

Fiber and wholegrain versionsBenefit

Plain couscous made from refined semolina has roughly 1.5 grams of fiber per 100 grams. Wholewheat couscous has about 5 grams, close to brown wheat, and the darker color and nuttier taste are the quickest way to tell the two apart on a shelf.

USDA FoodData Central, couscous

GlutenUnder study

Couscous is wheat and contains gluten, so it is not suitable for celiac disease. It is also not the same as millet or quinoa, which people sometimes substitute for it while assuming they are gluten-free.

US FDA, food labeling guide for wheat and gluten

FructansUnder study

Wheat-based couscous is high in fructans, and it is one of the grains listed as needing to be avoided during the elimination phase of a low-FODMAP diet. A portion of about 75 grams cooked sits in the high range.
