Strange calorie discrepancy - whole wheat pita
I bought whole wheat pita at the store, and it says that it has 140 calories per piece. The bread measures about 9" in diameter with a ruler. The NCCDB lists that an extra-large whole wheat pita bread (8.5" diameter) as having 298 calories. I know the NCCDB is supposed to be more accurate. Should I just trust that one, or is the bread I have perhaps just not as thick as what they used?
