Question explored with the scientific record
can one roti is equivalent to 40 to 50mg carbs
One roti (chapatti) contains about 19 grams of carbohydrate, not 40–50 mg.
The only direct evidence in the retrieved records comes from a 2013 study that analyzed the nutritional composition of ethnic foods consumed by South Asians in the UK [1]. It reports that a standard 44-gram chapatti provides 19.2 grams of carbohydrates [1]. That is roughly 19,200 mg, far above the 40–50 mg range in your question.
The confusion likely comes from mixing units. 40–50 mg is a tiny amount — about the carbohydrate in half a pea. A typical roti delivers roughly 19 grams (19,000 mg) of carbohydrate [1]. The exact number varies with the size, thickness, and flour type of the roti, but the order of magnitude is always grams, not milligrams.
| Item | Carbohydrate content |
|---|---|
| 1 chapatti (44 g) | 19.2 g (19,200 mg) [1] |
| Your hypothesis | 40–50 mg |
My call: the figure you asked about is off by a factor of about 400. One roti contains roughly 19 grams of carbohydrate, not 40–50 milligrams. Confidence: high, based on the single directly relevant food composition record retrieved.
