Hi Brian and Welcome!
(I ate turnip greens last night, so that is why the link is there but you can look up anything) has a bunch of information on each food you would want and pictures that indicate how good they are visually.
I'm thinking that you are interested in glycemic index. Here is a link to a sparkpeople article: www.sparkpeople.com/resource/nutrition_art
and you can do a google search for bigger list. A glycemic index number is also listed at NutritionData for each food you look up.
Best of luck on achieving your goals, and remember to reward yourself with non-food rewards for your achievements, as well as for sticking to your plans!
