Are you good about brushing your teeth and flossing on the regular? Having lots of sugar isn't what causes cavities, it's not keeping up your dental hygiene. So if you eat a lot of sugar but brush well on a regular basis, I would expect you to not get cavities. Genetics play a role as well. My mom never got cavities despite never brushing her teeth, whereas my dad could brush pretty regularly and still have a cavity or two when he got checked up. Sadly I inherited my dad's genes, not my mom's.
