nutrition software

[A. Cobb]

Hi again,

I am interested in finding out about software available for the layperson
to calculate Kcal requirements, analyze diets and recipes.  I also once
heard that there was software with a database of recipes and you could
enter a list of ingredients (ie what you have on hand in the fridge and
cupboards) and it would generate suggested recipes using those
ingredients.

Any ideas?? 
Thanks,
Amelia Cobb
