| Uncertainty notes |
Bagel size varies considerably; a large deli-style bagel could be 140-160 g and add ~100 kcal
Peanut butter quantity is a common variable; a generous spread could reach 50 g and add ~100 kcal
Jam quantity is generally a smaller source of variability |
Bagel size varies significantly; a large deli-style bagel (120–130 g) could add 75–100 kcal and 15–20 g carbohydrate. Peanut butter portion could easily range from 20 g to 45 g depending on how generously it was spread, which would shift fat and calories materially. |
Portion size of peanut butter and jam could materially change the calorie and fat estimate. |
