I can't keep PB in the house anymore. It's just too dangerous. I find myself walking by the fridge and sweeping a finger full here and there, and that stuff is so caloricaly dense a few swipes will add about 400 calories to my daily totals.
I used to have the same problem that JG1 has, but since I threw out the SF Smuckers I have been able to eat it again. I have about 3 tbs per day at separate meals. I am an Almond butter addict right now.
I had to stop eating peanut butter because mine is suicidal. If I go into the jar intending to get a tablespoonful, half a cup jumps on the spoon. I cannot in good conscience be a party to kamikaze PB.
