I think it would be helpful to a lot of people who rely on store-bought food for their rats to have a way to compare foods and also common places to get certain items like the Lab Blocks... The closest thing to Lab Blocks I've seen in the stores are the Kaytee Forti-Diet rounded block thingies... It would be nice to know if that would be a good choice... (I am seriously considering it because the food I use now, Nibble and Brain don't eat all of...)

Check the diet sticky in the health forum about foods...

Kaytee isn't recommended as it contains a chemical that may cause cancer. :)
