The energy density (ED) of a food is defined as theamount of energy in a specific weight of that foodand is usually expressed as kilojoules per 100 g (kJ/100 g). The macronutrient composition and moisture content of the food determine its ED,with foods higher in fat tending to have higher EDs than other foods and water-rich foods tending to have lower EDs than other foods.

What is’energy density’in food?
‘Energy density’ is the amount of energy (or calories) per gram of food. Lower energy density foods provide fewer calories per gram of food 鈥?this means that you can have satisfying portions of these foods with a relatively low calorie content.
What is energy density and nutrient density?
Energy density and nutrient density are important terms to understand when making food choices. Foods that are energy-dense contain a higher number of calories per serving, while foods that are nutrient-dense contain a higher level of vitamins, minerals, and other important nutrients with little or no added sugars or fats that raise calories.
Why do some foods have more energy density than others?
But some foods have more calories, more energy per weight, than others do. One component that might influence energy density for instance would be the water content of food. And a salad for instance, is a meal of relatively low energy density because there’s a lot of water in the vegetables that comprise a salad.
What foods have a low energy density?
Foods that contain large amounts of fiber and water have a lower energy density. Foods that are high in fat have a higher energy density. Foods with low energy density include high-fiber green and colorful vegetables. Watery foods like whole fruits tend to be less energy-dense, as well.
