Energy density refers to how many Calories (or kcal) there are per gram of food. More energy dense foods have lots of calories in a small amount of food, like fat, while less energy dense foods have fewer calories in a large serving, like celery. Note fruits and vegetables have very low energy density. Here’s some specific examples:
|chocolate chip bar||4.68||high|
|salsa (vegetable)||0.44||very low|
|green beans (vegetable)||.44||very low|
|grapes (fruit)||0.89||very low|
See a poster on the Volumetrics Diet which incorporates energy density and nutrient density into an intelligent dieting program.
