I don't mind at all! I'm certainly no expert but I'm always happy to share what I've learned. As for the bagel thing, I'd imagine that a bagel is the healthy alternative to the donut. =P It is still something that is small, portable and finger food and better for you than that white flour / sugar / fat laden donut.
Here is a great web site: Nutrition Data
If you're really interested in what foods are "best" for you, this site offers several ways to measure just that. You can visualize a food's nutritional value (or lack of it) with an easy to understand graphical pyramid.
It explains why the GL factor of a food is a much more important number to be aware of than GI. Oh oh, speaking of GI / GL, check this site
You can input recipes into Nutrition Data's site and have an analysis done on it. It gives amazing details. You can search on single food items and get the same information.
If you enter your height / weight and daily excercise level amounts, it will give you recommendations for the amounts of vitamins, minerals, fat / protiens / carbohydrates that you should consume.
It gives super weight loss tips, which really isn't about dieting at all but more about making lifestyle changes that we all should work towards.
None of the information there is ground breaking stuff. But it's great to have so much accurate and up-to-date information available in one spot.
