Came across this while surfing. Seems a good tool!
Nutrition Facts & Calorie Counter
NutritionData (ND) provides nutrition facts, Calorie counts, and nutrient data for all foods and recipes. There is a drop-down menu for several fast food establishments, too!
Quoting:
"ND tells you, in simple terms, what's good and bad about the foods you eat, and helps you select foods that best meet your dietary needs."
Also has a Nutrient Search Tool: Create lists of foods that are lowest in carbohydrates, highest in protein, or that match any other dietary restrictions or goals.
