Not OP, but I ate sooo much Kellogg's and General Mill's sugary products in high school for breakfast (pop tarts, eggo waffles, all the disgusting cereals you can name...), but I took Centrum daily and played a ton of basketball after school. Almost 1 can of coke a day after school. No heath problems as an adult. But of course, genetics come into play as well, no overweight parents or relatives.
