How to Determine the Nutritional Value of Food - FoodCrumbles The energy content of a food is given in kcal (often referred to as Calories) and/or kJ (kilojoule). Converting from kcal to kJ is a simple set calculation 1 kcal = 4,18 kJ Set conversion values Research has shown how much energy our body can make from these macronutrients. We know that: 1 gram of fats provides 9 kcal of energy Food Energy - an overview | ScienceDirect Topics The metabolic expenditure by an animal is often measured as the amount of heat produced; this is usually called respiration (R).The difference between M E and R is retained energy, usually termed production (P): M E −R=P.When an animal is deprived of food (C=0), body tissues are catabolized in order to support R, P is negative, and the animal loses body mass. Understanding food labels: portions, energy - Health24 Energy value a) Kilojoules As South Africa is a metric country, the energy value of foods must be expressed in kilojoules (kJ). So, if a food's energy value is listed as 500kJ per portion, then this is how much energy you will ingest when you eat a portion of this food. b) Calories or kilo-calories
