== Calories vs. Carbohydrates ==
Calories and carbohydrates are related but distinct concepts fundamental to nutrition. A calorie is a unit of energy, while carbohydrates are a type of macronutrient that the body uses to obtain energy.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> All macronutrients—including proteins and fats in addition to carbohydrates—provide calories. The<ref name="ref4" /><ref name="ref5" /><ref name="ref1" /> body requires energy from calories to perform all essential functions, such as breathing, circulation, and cellular processes. Carbohydrates are the body's primary and preferred source of this energy.

The<ref name="ref3" /> number of calories in a food indicates the amount of potential energy it contains. This is often measured using a device called a bomb calorimeter, which burns the food to determine how much heat it releases. Carbohydrates, along with proteins, provide approximately 4 calories per gram, whereas fat provides 9 calories per gram.

Carbohydrates<ref name="ref4" /><ref name="ref1" /> are molecules composed of carbon, hydrogen, and oxygen atoms and are found in a wide variety of foods. They are categorized as simple or complex. Simple<ref name="ref4" /> carbohydrates, like sugars, are digested quickly, providing a rapid source of energy. Complex<ref name="ref4" /> carbohydrates, such as starches and fiber, are digested more slowly, offering a more sustained release of energy. Foods<ref name="ref4" /> high in carbohydrates include grains, fruits, vegetables, and legumes.

| '''Definition''' || A unit of energy. || A type of macronutrient; a molecule made of carbon, hydrogen, and oxygen.

| '''Energy Content''' || A measure of energy itself. || Provide approximately 4 calories (kcal) per gram.
|-
| '''<ref name="ref4" /><ref name="ref1" />Dietary Sources''' || Provided by all macronutrients: carbohydrates, fats, and proteins. || Grains,<ref name="ref4" /><ref name="ref5" /> fruits, vegetables, legumes, and dairy products.
|-
| '''<ref name="ref4" />Types''' || Not applicable, as it is a unit of measurement. The source of the calorie (e.g., from fat or protein) is what differs. || Three main types: sugars (simple), starches (complex), and fiber (complex).

=== Nutritional Labels ===
On nutrition facts labels, the "Total Carbohydrate" value lists the combined total of dietary fiber, total sugars, and other starches in grams per serving. The label also shows the total number of "Calories" per serving, which is derived from the energy provided by the fat, carbohydrates, and protein in the food. Understanding the distinction between these two terms is useful for managing diet and energy balance. While<ref name="ref2" /> carbohydrates are a significant contributor to the total calorie count of many foods, they are not the same as calories.<ref name="ref1" />
