worse in what way? if a person ate of teaspoonful. just a teaspoonful of either of these food sources they would be just fine. one may have more calories than the other but when you compare it to the total day intake it would not make much of a difference. peanut butter has more protein but i don't know what kind of ice cream you are eating. who can eat just a teaspoonful?
is eating a large teaspoon full of peanut butter worse than eating a large teaspoon full of ice cream?
