Plain puffed rice
Puffed rice by the numbers
Plain puffed rice delivers 355 kcal per 100 g, almost all of it carbohydrate, with a glycemic index around 82. That combination makes portion size the single most important decision you make with a bowl of muri. This guide converts grams to calories, reads glycemic load off a real serving, and compares rice murmura with ragi murmura and poha.

Plain puffed rice has 355 kcal per 100 g, so every serving question is a gram question.
The per-100 g figure is the anchor: 355 kcal, 77.7 g carbohydrate, 7.45 g protein, 1.6 g fat and 4 mg sodium. Because the grain is puffed, it is mostly air by volume, which is why a cup looks generous but weighs very little.
In practice, a small 25 g katori lands at 89 kcal, a medium 40 g bowl at 142 kcal and a 50 g bhel base at 178 kcal. Those three numbers cover most home and street servings before anything is added.
A full 200 g packet adds up to 710 kcal. Eating straight from the packet is the most common way people overshoot, because the bag is treated as one portion when it is closer to eight small katoris.
A loosely filled cup of dry puffed rice weighs only 15-30 g, a two-fold spread that breaks any cup-based calorie estimate.
Puffed rice is one of the least dense dry foods in a typical kitchen. The same cup can hold 15 g or 30 g depending on how it was scooped, whether it was shaken down, and how fresh and crisp the grains are.
That spread is the difference between roughly 53 kcal and roughly 107 kcal for the same visual portion — a 100 percent error before you have added anything to the bowl.
A basic kitchen scale removes the guesswork in one step. If you do not have one, the next best method is to weigh the packet once, divide by the number of katoris you actually get from it, and use that as your personal reference.
Puffed rice has a glycemic index of about 82, and a 30 g serving carries a glycemic load of about 19.
Anything above 70 is classed as high-GI, so puffed rice sits firmly in that band. The number reflects how quickly the gelatinised starch is broken down and released as glucose.
Glycemic load is the more useful figure at the table. A 30 g serving has a GL of about 19, which is similar to a medium banana — meaningful, but not extreme, because the actual carbohydrate in 30 g of puffed rice is modest.
The practical consequence is that portion size, not avoidance, is the lever. Doubling the bowl to 60 g roughly doubles the glycemic load to the high thirties, which is where blood-sugar spikes become harder to manage.
Four reference figures: the per-100 g nutrition panel, the grams-to-calories ladder, the glycemic index bands, and the grain comparison.
Rice murmura, ragi murmura and poha look similar on a shelf but differ sharply on calcium, glycemic index and processing.
Ragi (finger millet) murmura carries 344 mg of calcium per 100 g, against 8-10 mg in rice murmura — a difference of more than thirty times. Its glycemic index is also lower, roughly 54-65 against about 82 for rice.
Poha is flattened rice, not puffed. The grain is pressed rather than expanded, so it keeps more density: about 350-360 kcal per 100 g, close to puffed rice, with a GI near 70.
The processing method matters for texture and cooking, not just nutrition. Puffing gelatinises the starch and makes the grain ready to eat; flattening leaves a grain that still needs rinsing, soaking or cooking.
For a calcium-focused diet, ragi murmura is the clear pick. For a low-GI snack, ragi again edges ahead. For a familiar breakfast that behaves like a light grain, poha at a controlled portion is the middle option.
