We're not a big fan of providing nutritional information for recipes.  We've found that the data varies terribly depending on the brand of ingredients used, ambiguous measurements and other factors.  We always recommend that users take any nutritional data with a grain of salt (pun intended) and do their own calculations if they are relying on it for health purposes.

That said, we are adding nutritional data to our recipes since it is such a highly requested feature.  We are adding the data as it is calculated so it won't be long until all recipes feature the information.
