The Nature of Coffee Beans and the Limitations of Drinking

Coffee is one of the most popular drinks in the world, and coffee beans are the basic raw material for making coffee. Coffee beans have a unique flavor and aroma, but there are also some restrictions on drinking. This article will explore these issues, focusing on the nature of coffee beans and their impact on human health.

1. Origin and processing of coffee beans

Coffee beans come from the fruits of coffee trees that grow in Asia, Africa, and Latin America. When the fruits are ripe, they are picked and exposed through processes such as peeling, fermentation, and drying. These seeds are what we often call "coffee beans." Only after being roasted can they be consumed or ground into powder with a special flavor and aroma.

2. Catechins and amines

Unprocessed or lightly processed (lightly roasted) coffee beans contain a large amount of catechins and amines. Catechins are a compound naturally found in plants that have antioxidant and anti-inflammatory effects. However, excessive intake of catechins may cause adverse reactions such as palpitations and insomnia.

Amines are a class of compounds produced during the fermentation process that are reduced after high temperature processing or deep roasting. These compounds include tyramine, adrenaline and histamine, which are related to the nervous system and may cause discomfort such as headaches and palpitations.

3. Caffeine content and its effects

The most well-known ingredient in coffee beans is caffeine. Caffeine is a stimulant neurotransmitter that provides alertness and excitement in the body. While this is a welcome effect for many people, excessive intake or sensitivity may cause side effects such as anxiety and insomnia.

The caffeine content of coffee beans varies according to the type and degree of processing. Generally speaking, lightly roasted coffee beans have a higher caffeine content, while darkly roasted ones have a relatively lower caffeine content. In addition, espresso and instant coffee usually contain more caffeine.

4. Drinking restrictions and precautions

Although drinking a delicious cup of coffee can bring pleasure and a boost in energy, for some people it may not be appropriate in all situations.

First, pregnant women. Since the placenta cannot effectively metabolize the caffeine consumed, excessive intake may increase the risk of miscarriage, premature birth, and low birth weight. It is recommended that pregnant women limit their daily intake to no more than 200 mg (about 1-2 cups).

The second is breastfeeding women. Although only a small part of it will enter breast milk after being absorbed by the digestive system, you still need to avoid drinking large doses to prevent affecting the baby's sleep quality or causing other Starbucks menu discomfort.

In addition, for patients with heart disease, hypertension, and gastric ulcers, the stimulating effect of caffeine may aggravate symptoms or cause other discomfort. For these people, it is recommended to limit intake or avoid drinking.

In addition, individual differences also need to be considered. Some people are more sensitive to caffeine, and even a small amount of intake may cause discomfort. Therefore, when drinking coffee, you should adjust it according to your own situation.

in conclusion

Coffee beans are the basic raw material for making coffee, with rich flavor and aroma. However, before enjoying the delicious taste, we also need to understand its nature and its impact on health. Although there are some drinking restrictions and precautions, enjoying a cup of good coffee in moderation can still bring pleasure and refreshing effects.
