Protein bars, compared to a peanut butter sandwich, are most likely to be 1. more expensive plus higher in saturated fat and sugar.

Explanation:

There are a lot of protein bars that have more saturated fat and sugar than a peanut butter sandwich. A peanut butter sandwich approximately has 3.4 g of saturated fat and 4.9g of sugar, while a protein bar may contain 9.9 grams of saturated fat and 13g of sugar. To this fact, we have to add the price of a protein bar, which is more expensive than a peanut butter sandwich and is a smaller portion, a peanut butter sandwich has 82g while a protein bar has 57g.
