Calories are a unit of energy that measure the amount of energy in food. Density, which is the amount of mass per unit volume of a substance, is not directly related to the measurement of calories. Calories in food are typically measured based on the macronutrients it contains, such as carbohydrates, fats, and proteins.
they provide energy or calories
The substance found in foods that is energy-rich is called macronutrients, specifically fats, carbohydrates, and proteins. These macronutrients provide the body with the energy it needs to function properly.

carbohydrate
The energy content of a piece of food is determined by its macronutrient composition, particularly the amount of carbohydrates, proteins, fats, and alcohol it contains. These macronutrients provide calories that can be converted into energy during metabolism. The energy content of food is typically measured in kilocalories or calories.

Nucleic acids, such as DNA and RNA, are not classified as macronutrients. Macronutrients typically refer to carbohydrates, proteins, and fats, which are essential for energy and overall bodily functions. Nucleic acids play a crucial role in genetics and the synthesis of proteins but are not directly used by the body for energy or structural purposes like macronutrients are.
The unit of measure for energy stored in food is typically represented in kilocalories (kcal) or kilojoules (kJ). This energy is derived from the macronutrients in food such as carbohydrates, proteins, and fats, and is used by the body for various functions and activities.
Food energy is measured in kilocalories (kcal) or sometimes referred to as calories in common usage. The energy provided by food is derived from its macronutrient content, primarily carbohydrates, proteins, and fats.
