How is the energy content of food measured?
- The food is ignited by an electric spark so it completely burns up. The temperature increase in the water is measured and the actual energy content of the food can then be calculated, either in old-fashioned calories or more modern joules.
How to calculate the energy content of food?
- Energy can be calculated using the formula: Q = mc ∆T. In the formula, Q = the energy in joules or calories, m = the mass in grams, c = specific heat and ∆T = the change in temperature which is the final temperature minus the initial temperature. The specific heat for water = 1 calorie/gram °C.

What is the measurement of energy content of food called?
Energy is measured in units of kilocalories (kcal) or kilojoules (kJ). One kilocalorie (1 kcal) is equal to 4.18 kilojoules (4.18 kJ). The amount of energy a food contains per gram is known as its energy density so we can describe fat as more energy dense than protein or carbohydrate.

How can the energy content of food be worked out?
A calorie is the amount of energy required to raise a volume of water a certain amount. This historically was determined by completely burning food surrounded by water. The Atwater system averages the components of food to determine a calorie count, because our bodies do not derive energy from certain types of food. In this system protein and carbohydrates add 4 kilocalories per gram to a food's total, whereas fat adds 9 kilocalories per gram.
What food content vitamin d?
What foods contain vitamin D?
- Very few foods in nature contain vitamin D. The flesh of fatty fish (such as salmon, tuna, and mackerel ) and fish liver oils are among the best sources [1,11]. Small amounts of vitamin D are found in beef liver, cheese, and egg yolks.
