Kuttu (buckwheat): names, nutrition, benefits and how to cook it

Kuttu is the Hindi name for buckwheat, a seed rather than a cereal grain. The 2015 review by Gimenez-Bastida and Zielinski puts the plant in the Polygonaceae family and calls it a gluten-free pseudocereal: people eat and mill the seed the way they do wheat or rice, but the plant is no cereal grass. The wheat in the English name is a name, not a family tie; the NHS puts wheat, barley and rye on its gluten list, and buckwheat belongs to none of that trio.

In an Indian kitchen kuttu turns up in two forms. Whole groats, the hulled seed, go into khichdi; the same seed milled becomes kuttu ka atta, the flour behind vrat-day rotis, puris and pakoras, dishes salted with sendha namak, not everyday salt. The flour and the groats are the usual stand-ins of North Indian vrat cooking, taking the place of the rice and wheat set aside on fasting days. What the gluten-free status means for coeliac diets, pack labels and the buckwheat allergy is on is buckwheat gluten free.

In English the seed is buckwheat and its flour is buckwheat flour, so kuttu ka atta translates directly; the botanical name is Fagopyrum esculentum Moench. The table below runs through the names, and the list is short on purpose: the USDA FoodData Central record for the seed carries just the English and scientific name, IFCT 2017 has no buckwheat entry, and the ICAR-IIMR vernacular lists pass the grain over as well. Every other language cell therefore shows a dash rather than a guessed word. The Hindi name kuttu, the one Indian name on record, comes from the Wikipedia article on buckwheat. Telugu, Tamil, Kannada and every remaining cell show the same dash, because a name that no published source carries is better left blank than invented.

The naming page explains each cell and untangles kuttu from its vrat-shelf neighbours: kuttu ka atta in English, Hindi and Indian languages.

IFCT 2017 has no entry for buckwheat, so the per-100 g figures on this page come from the USDA FoodData Central record for the whole seed: 343 kcal, 13.2 g of protein, 3.4 g of fat, 71.5 g of carbohydrate and 10 g of total fibre. The minerals worth knowing are 231 mg of magnesium and 460 mg of potassium, with 2.2 mg of iron, 2.4 mg of zinc, 18 mg of calcium and 1 mg of sodium. Sodium is the quiet one: at 1 mg per 100 g, nearly all the salt in a kuttu dish is the sendha namak the cook adds. Kuttu ka atta is the same seed milled whole, and the USDA lists the flour as whole-groat; a milled pack may read a little differently.

The glycemic index is on record too: the University of Sydney database holds four buckwheat entries, tested in Canada and Sweden, that run from 46 to 64 and average 53, which lands under 55, the Sydney ceiling for the low band. In kitchen terms a cup of groats weighs about 200 g and a cup of atta about 120 g, which sets the portion arithmetic: a bowl of kuttu khichdi comes to roughly 350 kcal, and the two-roti plate of kuttu roti to about 341 kcal. How kuttu compares with its shelf-mate rajgira sits on difference between kuttu and rajgira.

The full list of kuttu atta benefits takes eight points, one nutrient at a time; here is the short version. The protein and fibre do the everyday work: 13.2 g of protein per 100 g is the protein figure behind the atta, and the 10 g of fibre per 100 g backs its filling reputation, the satiety role the ICMR-NIN guidelines assign to fibre-rich foods and whole grains. Magnesium and potassium, at 231 mg and 460 mg, come along with every 100 g. Kuttu's iron is modest, 2.2 mg per 100 g, and to get more of it the ICMR-NIN guidelines advise vitamin C foods such as guava or orange after the meal.

The 2015 review by Gimenez-Bastida and Zielinski describes buckwheat grain as a highly nutritional food component and lists the effects attributed to it, lower plasma cholesterol, anti-inflammatory and antidiabetic actions among them, mostly from in vitro and animal work whose authors say the bioactive compounds may be only partially responsible. No gluten, and a glycemic index of 53 that the Sydney scale places in its low band, rounds out the list. Each claim and its source, plus the side effects, is on the kuttu atta benefits page.

For most people kuttu is an ordinary grain, and two cautions cover nearly everything else. Buckwheat allergy comes first: a 2024 review in the journal Current Allergy and Asthma Reports finds buckwheat allergy a significant concern in Asia and divides it into three presentations, immediate food allergy, FPIES (food protein-induced enterocolitis syndrome) and FDEIA (food-dependent, exercise-induced anaphylaxis); the published studies come mostly from Japan and Korea. Anyone who has reacted to buckwheat should leave kuttu out entirely, and a child's reaction goes to a paediatrician before kuttu is tried again. Being gluten-free does not make kuttu allergen-free: a person with a buckwheat allergy must avoid it just the same, and a wheat-free kitchen is no protection.

The second is fibre in a hurry: switching from a low-fibre day straight to kuttu at every meal can unsettle the stomach, so bring it in gradually and drink enough water. The allergy detail, and the pack checks a gluten-free kitchen needs, are on is buckwheat gluten free.

The vrat shelf holds two flours that are easy to confuse with kuttu, and both have their own comparison page. Rajgira is amaranth: against kuttu it carries several times the iron and calcium, while kuttu wins on fibre, and the protein is a near tie. Neither flour is the other, and neither is interchangeable in a recipe; the numbers sit side by side on difference between kuttu and rajgira.

Singhara atta, by contrast, comes from the water chestnut, a water plant rather than a grain. Kuttu's per-100 g table and GI are published; for singhara atta no such figures appear in the sources quoted here, so the choice between the two runs on the dish and the pack label. That honest blank is the subject of is kuttu and singhara same.

Whole groats: rinse them, soak them for half an hour and add one and a half cups of water per cup of kuttu. The kuttu khichdi recipe does this in a single wide pan: potato cubes and roasted groundnuts go in with the grain, a ghee-and-cumin tempering opens the pot, and a covered simmer with one stir keeps every grain separate. One pot, three bowls, about 35 minutes of work, served with a spoon of curd or cucumber raita and a squeeze of lemon.

Kuttu atta: the flour will not stretch the way wheat does, because it has no gluten, so kuttu flatbreads are patted with wet hands rather than rolled. The kuttu roti recipe kneads in one boiled potato, mashed, plus warm water up to half a cup, and pats out four rotis on a greased plate in about 45 minutes. The same dough, thicker, becomes a paratha, and a looser batter becomes chilla; for fasts the salt throughout is sendha namak. The buckwheat recipes roundup carries the remaining dishes, two lines at a time.

Whole groats keep for many months in an airtight jar or tin in a cool, dry cupboard. Kuttu atta is the fragile half of the pair: keep the pack sealed, cook with it while it smells fresh, and discard flour that has turned musty or bitter. Cooked kuttu dishes belong in the fridge and, following the UK Food Standards Agency's advice on leftovers, should be eaten within two days.

Two dishes carry the kuttu meal and both have full step-by-step pages: kuttu khichdi for a one-pot lunch and kuttu roti for the flatbread. The buckwheat recipes roundup adds six quick methods around them, chilla and pakora for the snack hour, puri, paratha and halwa for the rest of the vrat menu, and dahi bhalla for a cold plate, with sendha namak noted on the savoury dishes. Fast-day or ordinary, every dish starts from the same two forms: soaked groats in a pot, or atta in a dough. Between them, the two recipes use both forms of kuttu: whole grain in the khichdi, atta in the roti.

Whole groats suit khichdi and keep longest; atta suits rotis, puris and chilla, and is best bought in a size the kitchen will finish quickly. Read the pack in both cases. Kuttu ka atta should name buckwheat alone, a gluten-free kitchen should look for a wheat-sharing warning on the label, and an organic pack should carry a certification mark; a pack that only says natural makes no certified claim. Milled flour is the more perishable form, so buy it in a size that will be used up fast and check the date on the pack.

What is kuttu?

Kuttu is buckwheat, whose seed carries the botanical name Fagopyrum esculentum Moench; it is sold as whole groats or milled into kuttu ka atta. Its USDA FoodData Central figures are 343 kcal, 13.2 g of protein and 10 g of fibre per 100 g, and a 2015 review classes the seed as a gluten-free pseudocereal, from the Polygonaceae family.

Is kuttu a millet?

No. Kuttu is a pseudocereal: the 2015 review places buckwheat in the Polygonaceae family, outside the cereal grasses, so it is not a millet either. Shops often shelf it with the fasting grains, and the ICAR-IIMR millet review lists buckwheat among gluten-free grains, which adds to the mix-up, but the plant is not a millet.

Can kuttu atta be eaten in fast?

Yes. On the Navratri and Ekadashi fast days, when wheat and rice are set aside, kuttu atta turns into the day's roti, puri, pakora and khichdi, seasoned with sendha namak. The khichdi starts from whole groats and the roti from the atta, with the rest of the menu in the roundup; fasting customs differ between households, so keep your own.

Is buckwheat healthy?

Yes, as an everyday grain eaten in normal portions. Per 100 g the seed gives 13.2 g of protein, 10 g of fibre and 460 mg of potassium (USDA FoodData Central), carries no gluten, and its glycemic index of 53 sits inside the low band. The eight-point list, each claim with its source, is on the kuttu atta benefits page.

Does kuttu atta have gluten?

No. The atta is milled from buckwheat, a gluten-free pseudocereal per the 2015 review, and buckwheat stands outside wheat, barley and rye, the cereals the NHS names as gluten's home. A shop-bought pack still needs its label read, especially where the flour shares a line with wheat.

How to eat kuttu atta?

Start with the two dishes that carry full recipes: the roti, whose dough is patted rather than rolled because kuttu will not stretch, and the khichdi, which cooks the whole groats in one pot. Puri, pakora, chilla and halwa take the same atta further, and the buckwheat recipes roundup lists them all.

Is kuttu and singhara same?

No. Kuttu is buckwheat, while singhara atta is milled from the water chestnut, a water-grown plant, and the two are not interchangeable. Both flours share the vrat shelf, and that shared shelf is where the confusion begins; only kuttu has published per-100 g figures. The side-by-side lives on the kuttu vs singhara page.
