In order to help people who are interested in counting calories, here is a list of sites which are useful and have lists of calories for various foods, as well as the ability to track and record the amount of calories you intake daily:
http://www.fitday.com This is the site i use myself for counting calories in the foods i eat
http://www.calorie-count.com/ This site is similar to fitday but a bit more sophisticated i would say
http://www.dietfacts.com/ This site has several restaurants listed, mostly in the United States
http://www.caloriescount.org/ I have not personally used this site but it looks pretty good.
http://calorielab.com/index.html I have also not used this site but it looks informative
http://www.calorieking.com/ another massive food nutrition database with several food listings, also recipes and articles
please feel free to add your own sites that you have useful in counting calories!
