Do pure coffee beans have calories? Uncover the energy secrets of coffee beans

The Power of Coffee Beans

Coffee is an indispensable drink in many people's daily life, and the main ingredient of coffee is coffee beans. We often hear that food has calories, but does pure coffee beans have calories? This article will explore this issue.

What is Calories?

First, we need to understand what calories are. Calories are a unit of measure for the energy contained in food, usually expressed in kilocalories (kcal) or kilojoules (kJ). The human body obtains energy by eating food, and different foods contain different calories.

Do pure coffee beans contain calories?

Pure coffee beans do not release most of their energy before they are processed. In fact, in modern society, few people directly consume unprocessed pure coffee beans. Usually, we roast, crush, brew, etc. before drinking.

Therefore, under normal circumstances, pure coffee beans do not directly provide calories.

Coffee beans' energy source

Although pure coffee beans themselves have no calories, after processing, the coffee we drink does contain a certain amount of energy. This is because during the processing, some substances are released and mixed with water to form the coffee we drink.

First, when coffee beans are roasted, the carbohydrates in them begin to break down and produce aroma and flavor. These carbohydrates are mainly in the form of glucose and pectin. When we brew coffee, these carbohydrates dissolve in the water and become part of the drink.

Secondly, a small amount of fat is also produced during the roasting process. Although the amount is small, it probably does not contribute much to the total energy when making espresso.

Therefore, coffee consumed after processing does contain a certain amount of energy.

How to calculate the energy intake from drinking coffee?

The energy consumed by drinking coffee mainly comes from the carbohydrates in it. Generally speaking, every 100 ml of black coffee contains about 1-2 grams of carbohydrates. According to the calorie calculation formula, each gram of carbohydrate provides 4 kcal (or 17 joules) of energy.

Therefore, if we drink 200 ml of black coffee, the carbohydrate intake from it is about 2-4 grams. According to the above formula, the energy provided by these carbohydrates is about 8-16 kcal (or 34-68 joules).

It should be noted that the energy contained in coffee will increase further after adding other ingredients such as milk and sugar.

in conclusion

Pure coffee beans themselves do not contain a significant number of calories. However, when consumed after processing, some carbohydrates and a small amount of fat are dissolved in them, and when other ingredients are added, the total energy load may be further increased.

Therefore, when it comes to controlling weight and energy intake, we still need to be careful about how much coffee we consume and what ingredients we add.
