In response to Wahiduddin Mahmud's remark Rushad Faridi provided the following information in the ERG meeting on 30th March: 100 gm potato has 93 KCal, 100 gm rice has 350 KCal. Thus, as long as the price of rice is less than 3.5 times the price of potato, calorie per Taka will be more from rice! Currently, it is little more than 2 times.
