Coffee Primer: What are the pros and cons of drinking coffee?

In the past, people who wanted to experience a petty-bourgeois lifestyle would choose to drink coffee, but now there are more and more types and brands of coffee. Although it is no longer synonymous with petty-bourgeois lifestyle, many urban white-collar workers cannot do without coffee due to work pressure. So what are the advantages and disadvantages of drinking coffee for a long time?

1. Benefits of drinking coffee

1. Can prevent gallstones

Most of the coffee we are exposed to contains caffeine, and the main function of this substance is not only to stimulate the contraction of the gallbladder, but also to reduce the cholesterol in the bile. Patients who drink two to three cups of coffee a day have a much lower chance of suffering from gallstones than those who do not drink coffee.

2. Protect cardiovascular system

Because it is rich in polyphenols, which are commonly known as flavonoids, it not only improves the body's antioxidant capacity, but also has a positive effect in protecting the cardiovascular system.

3. Prevent and treat gout

Gout occurs because the body's uric acid level rises. Drinking coffee regularly can lower uric acid levels, thereby reducing the incidence of gout.

4. Refreshing effect

Modern people's life and study are fast-paced. The direct reason why many people choose to drink coffee is to refresh themselves, which is also one of the biggest benefits of coffee. The caffeine rich in coffee can stimulate the nerves. When you feel sleepy and weak and your brain can't keep up with the rhythm, you might as well have a cup of coffee to make your brain work faster.

5. Weight loss effect

For those who are pursuing weight loss, coffee has a weight loss effect, especially after a meal, the effect is more obvious. However, it should be noted that black coffee has a real weight loss effect. Other coffees may contain cream, sugar and other substances and cannot help with weight loss.

6. Beauty effect

Coffee also has skin care and beauty effects. It contains a substance called linoleic acid. After entering the body, this substance can help enhance the elasticity and contraction of blood vessels, effectively promote blood circulation, and thus play a good role in preventing blood clots. In addition, coffee can also promote venous return in the body, thereby helping to enhance skin metabolism, making the skin elastic and achieving skin care and beauty effects.

1. Disadvantages of drinking coffee

1. Drinking late at night affects sleep

Because coffee can refresh the brain and the effect lasts for a long time, in order to have a good sleep quality, you should stop drinking coffee after dinner. If you drink coffee too late, it will cause nerve excitement and affect sleep.

2. Avoid drinking coffee if you have poor digestion

Friends with digestive system diseases should also drink less coffee, because coffee is a stimulating drink. The tannins it contains will stimulate the gastrointestinal tract after entering the gastrointestinal tract, causing excessive secretion of gastric acid, thereby inducing stomach discomfort. If friends with stomach problems want to drink a cup of coffee, they must avoid drinking it on an empty stomach.
