Rohu isn't a flashy, headline-grabbing fish like salmon or tuna. It's a quiet, everyday staple across South Asia, and frankly, it's wildly underrated. This freshwater carp is a fantastic source of lean protein with virtually no carbs, making it one of the most straightforward, blood-sugar-friendly proteins you can put on your plate. Forget complicated nutrition rules; rohu is simple, clean, and incredibly versatile.
↑ Rohu is most often enjoyed in fragrant, spiced curries.
The quiet, everyday staple
If you grew up in India, Bangladesh, or Pakistan, you already know rohu. It's a freshwater fish from the carp family, and it's a fixture on the dinner table. Its flavor is mild and not overtly 'fishy', with a firm, flaky texture that holds up beautifully in the curries and spiced gravies it's famous for.
For those of us who didn't grow up with it, it's worth seeking out. It's an incredibly straightforward, healthy protein. No carbs, very little fat, and a clean taste that makes it a blank canvas for spices.
IN ONE LINE
Rohu is a lean, high-protein freshwater fish with zero carbs, making it an incredibly stable and healthy choice for almost any diet.
Rohu nutrition facts
Here's the nutritional breakdown for a 100-gram (about 3.5 ounces) raw fillet of rohu fish. That's a typical small, single-serving piece.
The story here is beautifully simple: protein. With over 18 grams of high-quality, complete protein in a small fillet and fewer than 100 calories, rohu is incredibly efficient nutrition. It’s what we call 'nutrient-dense'—you get a lot of nutritional benefit for a very low calorie cost. The fat content is minimal, making it a much leaner choice than many other animal proteins.
Rohu's Glycemic Index: The Zero-Carb Advantage
Glycemic index (GI) measures how quickly a food containing carbohydrates raises your blood sugar. Since rohu fish contains zero carbohydrates, it has a glycemic index of effectively zero. It simply does not impact blood sugar levels on its own.
This makes it an ideal food for anyone managing blood sugar, including people with diabetes or insulin resistance, as well as those following very low-carb diets like keto. When you see it next to foods that do contain carbs, the difference is stark.

How to cook it right
Rohu's mild flavor is its greatest asset, but it needs a little help to shine. Here are a few tips to get the best out of it.
01
Don't overcook it.
Like any lean fish, rohu can dry out. Cook it until the flesh just turns opaque and flakes easily with a fork. That's it.
02
Embrace spices.
Rohu is a perfect vehicle for flavor. Turmeric, cumin, coriander, ginger, and garlic are its best friends. A simple spice rub before pan-searing works wonders.
03
Steam, bake, or pan-sear.
These methods preserve its delicate texture without adding excessive fat. While fried rohu is delicious, it's best as a treat.
04
Watch for bones.
Rohu is a bony fish, with fine 'pin' bones running through the fillet. Eat it mindfully, and be careful when serving it to children.
