What do 200 calories look like?
I thought you might enjoy this page on Wisegeek.com, which shows what 200-calorie servings of dozens of different foods look like. The difference between 200 calories worth of broccoli (an entire plate) and 200 calories worth of peanut butter (a small dab) is a perfect illustration of the concept of calorie density. Nutrition Data's Fullness Factor is another tool that helps you find foods that fill you up on fewer calories.

In fact, it's not quite that precise. The 4/4/9 equation is an approximation. In reality, the amount of calories per gram can vary from food to food and the variation tends to be greatest in carbohydrate foods because of things like fiber and sugar alcohols.
Also, the calories for carbohydrates are computed "by difference." That means that the analyzing lab extracts the protein and computes the amount of calories it contains, then the fats and alcohols, and then the rest is assumed to be carbohydrate.

Hello,
As far as I have heard, 1g protein=4 kcal, 1g carbs=4 kcal, and 1g fat=9 kcal. I was wondering if you know why these numbers rarely ever add up correctly on the site. The calories from carbs seem to be off by the greatest margin and almost never are carb grams x 4 = carb calories. Thanks.

Hi,
I am confused between nutrition facts that labeled calories and Calories. What is the difference between lower case c and capital C? Does it measures the same? Like, how many calories is in a cup of milk ? I would also like to know what is kj and the translation to calories content?Give me an estimate of how much kj is in a cup of milk? I've always thought the calorie content on the product was the same nomatter if it was with either C's. Thank you.
