calories
Calorific value. One calorie = 4.178 joule
Yes, it is a noun. It is a unit of energy, often expressed as heat, or as the energy value of food.

The measure of how much energy is derived from a serving of food is typically expressed in calories or kilojoules. This energy content indicates the amount of energy the body can obtain from the food after digestion and metabolism. Nutritional labels often provide this information to help individuals assess their energy intake relative to their dietary needs.
The amount of oxygen that's consumed when you burn your food is an indirect measure of the amount of energy that's released from the food. Bomb calorimeters are sometimes used to measure the energy content in food.
Joules (J) or kilocalories (cal) (kcal in Europe)
The amount of energy in food is determined by measuring its macronutrient content, specifically carbohydrates, proteins, and fats, as each provides a different caloric value. Scientists use calorimetry to assess the total energy content, often through bomb calorimetry, which involves burning the food in a controlled environment to measure the heat released. This energy is typically expressed in calories or kilojoules. Additionally, food labels provide energy content based on standardized calculations of these macronutrients.
Food energy is usually measured in calories.
