As soon as the lid of the coffee is opened, the mellow milk flavor comes with the aroma of flowers and fruit of the coffee. I can't wait to take a sip. The warm sour, bitter, and slightly sweet taste spreads in the mouth, which is not only a sense of satisfaction, but also a source of spiritual comfort for many office workers.

Xiaolan (a pseudonym), a 30-year-old office worker, is addicted to coffee and feels that something is wrong as long as she doesn't drink it for a day, but soon after drinking coffee, there is always a stir in the stomach and must be liberated by flushing the toilet immediately, so that she has to "count the opportunity" every time she drinks coffee. so that there is no way to ask for help.

"Research statistics show that, like Xiaolan, one in three people will have a defecation every time they drink coffee," said Wu Chih-ying, an attending physician in the family medicine department of Shuanghe Hospital.

A study published in the journal Gut found that about 29% of the participants received a "shit call" within 20 minutes after the first sip of coffee.

The researchers thought it was caffeine, but oddly enough, other caffeinated drinks, such as tea and soda, did not accelerate gastrointestinal peristalsis.

Later, scientist S.R. Brown discovered that drinking coffee produces a sense of defecation, which is caused by an "unknown ingredient" in coffee that promotes gastrin secretion in the stomach and accelerates the peristalsis of the sigmoid colon. Usually get up in the morning to drink on an empty stomach, gastrointestinal peristalsis is the most obvious, and patients with intestinal mania, women are more likely to be stimulated by coffee.

The "chlorogenic acid" in coffee is good for health, including eye protection, weight loss and blood pressure reduction. )

Long-term use of coffee to defecate and be careful not to drink constipation

Although the effect of drinking coffee is similar to taking a laxative, constipation people should not be happy too early. Wu Chih-ying points out that by drinking coffee for a long time, it is easy to gradually paralyze the intestines and lose the ability to wriggle on their own, eventually leading to constipation without coffee.

If you drink coffee in order to relieve constipation, you will also bury the hidden worry of excessive caffeine. According to the 2016 US Food study, adults' daily caffeine intake is limited to 400 mg, mommy intake is limited to 200 mg during breastfeeding, and no more than 200 mg at a time, so as to avoid side effects such as caffeine addiction and palpitations.

Wu Chih-ying cautioned that if you want to get rid of constipation, you still have to go back to the basics, replenish high-fiber fruits and vegetables, drink enough water every day, and let the intestines peristalse on their own.

The following groups had better stay away from coffee:

1. Twelve-year-old children with underdeveloped heart function are not recommended to drink coffee.

two。 It is not suitable for pregnant women to drink coffee during pregnancy so as not to affect the fetus.

3. Cardiovascular dilatation during drinking and exercise, caffeine intake is more likely to cause palpitations, coffee is best not to touch

Note: at present, for freshly brewed coffee in China, caffeine content is distinguished by red, yellow and green. "Red" represents more than 201 milligrams of caffeine per cup, "yellow" represents 101 to 200 milligrams of caffeine per cup, and "green" represents less than 100 milligrams of caffeine per cup.
