Pixy stix certainly aren't healthy, but among candies they're maybe the lesser evil because they (and Sweet Tarts and similar things) are made with glucose (dextrose) and no fructose. It's sad people are made to think agave syrup is a healthy "natural" alternative to sugar because it's got so much refinery-manufactured fructose that I like to think of it as like high fructose corn syrup on steroids.
