It doesn't have to be pleasure, but it doesn't have to be torture either. There are many things that bring us pleasure and food is just one of them.
The problem with not seeing food as potential pleasure is that all the people in our lives will do anyway. I don't want to be the girl who brings her own lunch to a picnic. I don't want to eat before I go to a party. I don't want to watch other people enjoy food while I can't. I don't want to feel like I'm powerless in front of food, like I can't meet my friends out for drinks and dinner. I'm a social creature and social functions serve food. I have to learn to live in peace with that.
"If you pay attention to when you are hungry, what your body wants, what you are eating, when you've had enough, you end the obsession because obsession and awareness cannot coexist." - Geneen Roth
