Basic ingredients and classification of coffee beans

Coffee beans are the core raw material of coffee drinks, and their quality directly affects the flavor and taste of coffee. Coffee beans are mainly divided into two categories: Arabica beans and Robusta beans. Arabica beans usually have higher acidity and rich flavor, and are the first choice for high-quality coffee; while Robusta beans contain more caffeine and taste bitter, and are often used in instant coffee and espresso.

Antioxidants such as chlorogenic acid have anti-inflammatory and antioxidant effects, helping to neutralize free radicals in the body, thereby protecting cell health.

These components change during the roasting process, forming the unique flavor and aroma of coffee. Understanding these basic knowledge will help you choose coffee beans that suit your taste and better control the amount you drink to avoid possible health risks.

A practical guide to drinking coffee wisely

In order to drink coffee properly, you first need to control your daily caffeine intake. It is recommended that adults consume no more than 400 mg of caffeine per day, which is equivalent to four cups of regular coffee. You can monitor your total caffeine intake by recording your daily consumption to avoid exceeding the maximum recommended by health.

Choosing the right type of coffee is also key. Arabica beans have a lower caffeine content and are suitable for people who are sensitive to caffeine, while Robusta beans contain more caffeine and are suitable for situations where a stronger refreshing effect is needed. Choosing low-caffeine or decaffeinated coffee can reduce caffeine intake, especially when drinking it after dinner, which can effectively avoid disturbing sleep.

You also need to pay attention to the time you drink coffee. The best time to drink coffee is in the morning, when caffeine can help you stay alert and improve your work efficiency throughout the day. In the afternoon or evening, try to reduce your coffee intake to avoid affecting your sleep quality at night. If you need to drink coffee in the afternoon or evening, it would be more appropriate to choose low-caffeine coffee or reduce the amount.

Finally, it is also important to combine eating habits. Coffee should be paired with a balanced diet and should not be consumed on an empty stomach to reduce irritation to the stomach. When drinking coffee, you can add some milk or creamer, which can not only improve the taste but also relieve the irritation of coffee to the stomach.
