I assume pb is peanut butter. Be careful of natural peanut butter. Unfortunately, a lot of it will sit on the shelf for quite awhile and the invisible mold in peanut butter can lead to significant alfatoxin levels. I had some bad liver readings one time and it was when I was eating a lot of just this. I can't prove that was the problem, but it made me pause and reflect.
Of course, pb may stand for "pickled beets" and, if so, ignore the above.
