Kj to kcal

Everything we consume contains energy our bodies use to move, grow and maintain health. To work out how much energy is in different foods and drinks, we need to first look at a few core concepts. In human nutrition, the amounts of energy needed to maintain health, and to fuel a body, are much larger than the tiny singular calories used to heat up a gram of water. The energy stored in food and drinks is released when the body breaks down one or more of the four macronutrients inside the food carbohydrates, proteins, fats, alcohol. The body then uses that energy for activities such as keeping our heart beating, our lungs breathing and our muscles moving. When energy in food is estimated, it is the amount of energy food and drinks provide for these bodily processes. The four macronutrients provide different amounts of energy :. This gold-standard method involves placing a small sample of food or drink inside a device known as a bomb calorimeter. The food is burned in the presence of oxygen, releasing heat. The amount of heat released is directly related to the amount of energy in the food, allowing a calculation to be made. This method is most commonly used for foods rich in fats and is considered the most reliable but expensive method. The second method, the Atwater system, is a much less expensive method for estimating energy content.
