  • How is energy measured?

  • How is Energy Measured? Understanding BTUs, therms, quads, and more. A British Thermal Unit (Btu) is a measure of energy content, usually used to describe the energy content of fuels. Because a Btu is so small, energy is usually measured in millions of Btus.

  • What is the best measure of adequate energy intake?

  • Weight is the most sensitive measure of adequate energy intake and is affected earlier and to a greater extent than linear growth or head circumference by dietary inadequacies. For accuracy, infants should be weighed without clothes or diapers.

  • What does reported energy intake mean?

  • Reported energy intake: Energy consumed as estimated from dietary surveys. Dietary surveys: Questionnaires and forms for collecting food intake information. Stable isotopes: Atoms that do not emit radiation.

  • What is the energy intake from food?

  • Energy intake is defined as the total energy content of foods consumed, as provided by the major sources of dietary energy: carbohydrate (4 kcal/g), protein (4 kcal/g), fat (9 kcal/g) and alcohol (7 kcal/g).
