In human nutrition, empty calories are those calories found in foods and beverages (including alcohol) [1] composed primarily or solely of calorie-rich macronutrients such as sugars and fats, but little or no micronutrients, fibre, or protein. [2] Foods composed mostly of empty calories have low nutrient density, meaning few other nutrients ...
The calorie is a unit of energy that originated from the caloric theory of heat. [1] [2] The large calorie, food calorie, dietary calorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin ). [1] [3] The small calorie or gram calorie is defined as the ...
Specific energy or massic energy is energy per unit mass. It is also sometimes called gravimetric energy density, which is not to be confused with energy density, which is defined as energy per unit volume. It is used to quantify, for example, stored heat and other thermodynamic properties of substances such as specific internal energy ...
In the Arrhenius model of reaction rates, activation energy is the minimum amount of energy that must be available to reactants for a chemical reaction to occur. [1] The activation energy ( Ea) of a reaction is measured in kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). [2] Activation energy can be thought of as the magnitude ...
In thermodynamics, an exothermic process (from Ancient Greek έξω (éxō) 'outward' and θερμικός (thermikós) 'thermal') [ 1] is a thermodynamic process or reaction that releases energy from the system to its surroundings, [ 2] usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g ...
A calorimeter is a device used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types.

A sample nutrition facts label, with instructions from the U.S. Food and Drug Administration [1] The nutrition facts label (also known as the nutrition information panel, and other slight variations) is a label required on most packaged food in many countries, showing what nutrients and other ingredients (to limit and get enough of) are in the food.
