Definition: You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Input: These taste great!  And it's true what other reviewers have said about the consistency being good and them not sticking in your teeth.  However, as an energy boost for running, they don't do a thing for me.  In fact, they actually cause a stitch.  So I just eat them whenever I feel I need a sugary 'fix'.
Output:
Negative
