Sports drinks, gels, gu, gummies, etc are awwwfuuulllll for your teeth. Especially if you're riding, the sugar just sticks (if I'm running and eating gummies, I spend miles just picking them out of my teeth...sorry for tmi)

I switched to nuun and try to eat real food if possible (I love little baked potato strips but they squish really easily if you fall on them...so gross). If I'm eating something really sugary on a ride I try to swig some water/nuun, swish it around, and spit it out after I eat.
