Coffee beans have high calories, why is coffee low in calories?

Coffee is a must-have drink for many people every morning. It can refresh the mind and increase energy. However, although coffee beans themselves are high in calories, the coffee produced does not have very high calories. This has aroused people's curiosity and exploration about why coffee has low calories.

1. Coffee beans and their production process

First we need to understand coffee beans and their production process. When we talk about "coffee", we actually mean the liquid extracted from the "coffee beans" after they have been processed and roasted. In this process, the ingredients that are originally rich in high energy and nutrients (such as protein, carbohydrates, etc.) are soaked in water and separated through a filter.

2. Loss of water-soluble components

When we put the crushed or whole beans into the filter cup for brewing, the water-soluble components in the coffee beans will be absorbed and dissolved by water during the soaking process. These water-soluble components include caffeine, acids and other organic compounds. Since these components have low molecular weight and thermal stability, they are easily extracted during the brewing process and are effectively captured on the filter.

3. Filter out the grease

Another reason why coffee has low calories is that the oils are filtered out. When we brew coffee beans, the oils rich in them are also extracted along with the liquid. However, the filter paper or metal mesh used in the production process can effectively prevent these oils from passing through and keep them outside the filter cup.

4. Add other seasonings

In addition, many people like to add creamer, sugar or other condiments to their coffee to increase the taste and flavor. However, these additional condiments are usually high-energy foods, such as milk and sugar. Therefore, the total calories of coffee depend on the type and amount of condiments added by the individual.

5. Coffee making method

Finally, the calories in coffee are also related to its preparation method. Different brewing methods (such as drip, espresso, French press, etc.) will affect the types and contents of substances extracted from coffee. Some brewing methods may cause more oils to be extracted, thereby increasing the calories in coffee.

in conclusion

In summary, although coffee beans are high in energy and nutrients, the resulting coffee is not very caloric due to the loss of water-soluble ingredients, the filtration of oils, and the addition of other condiments. In addition, different production methods will also have an impact on the final result. Therefore, when enjoying a delicious, healthy and low-calorie cup of coffee, please remember that there are many scientific principles hidden in it.
