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 the difference between high and low energy density food?
A low energy density food has fewer calories, and a high energy density food has more calories. Most of the energy density in food comes from fat and carbohydrates. Low-energy-density foods also have these components, but they have more water and fiber, making them less dense.
What is energy density?
Andrea Rice is an award-winning journalist and a freelance writer, editor, and fact-checker specializing in health and wellness. Energy density is the amount of energy, as represented by the number of calories, in a specific weight of food. 1 锘?Energy-dense foods have a large number of calories per serving.
How do you find the energy density of a food?
To calculate low energy density, you need to divide the calories in a quantity of food by its weight. For example, if a portion of food has 340 calories and weighs 142 grams, its energy density will be 340cal/142grams = 2.4 cals/grams.
