Can coffee beans be eaten directly? Why?

Coffee beans are a common brand of coffee food, but they are not usually eaten directly. This is because coffee beans are very hard before roasting and difficult to digest and chew. In addition, unroasted coffee beans contain a lot of bitter substances and acidic components, which make them taste very bitter.

First of all, unroasted coffee beans are difficult to digest and absorb. Due to their high hardness, they cannot be fully broken in the mouth and cannot be completely digested in the gastrointestinal tract. This means that most of the nutritional value will not be absorbed and utilized by the human body. In addition, unprocessed coffee beans may also cause discomfort such as flatulence and diarrhea.

Secondly, before being roasted, coffee beans contain a large amount of bitter substances and acidic components. These substances will give consumers an extremely bitter and irritating taste and may irritate the gastric mucosa. In addition, after long-term soaking or excessive intake, these components may also cause a series of health problems, such as excessive stomach acid and indigestion.

To sum up, the main reason why coffee beans are not usually eaten directly is because of their hardness and bitterness. In order to make coffee beans delicious and easy to digest, cafes usually roast them, grind them into powder, and brew them into coffee drinks. In this process, roasting can make coffee beans more fragile and easier to digest, and can also reduce the content of bitter substances. Therefore, if you want to enjoy the delicious coffee flavor, please choose processed roasted coffee beans.
