Top 10 coffee drinking questions, solved at once

Drinking coffee has long become a necessity in life, but when drinking coffee, there are still many questions in the mind. Will drinking coffee hurt the stomach? Will it cause osteoporosis? How many cups can I drink a day? The following report contains complete answers.

Coffee lovers need to know how to drink coffee in a healthy way.

1. Does espresso really have more caffeine?

Answer: Most people are often misled by the name and think that the full-flavored espresso (coffee) has a high caffeine content. In fact, the caffeine content is related to the roasting method and extraction time. Lightly roasted coffee beans and coffee that is extracted for a long time, such as "drip" coffee, have a higher caffeine content than high-pressure, short-time extracted espresso.

2. Will drinking coffee cause osteoporosis?

Answer: This is the doubt in the minds of coffee lovers. Osteoporosis is related to gender, age and eating habits. Lack of exercise, lack of sun exposure and calcium deficiency may lead to osteoporosis. Although caffeine is a risk factor for osteoporosis, there is no direct evidence that caffeine can cause osteoporosis. However, for women with low calcium intake, drinking more than 2 cups of ground coffee a day will worsen bone loss. Postmenopausal women should be careful. In addition to reducing caffeine, they can also exercise more and supplement calcium to avoid osteoporosis.

3. Will drinking coffee damage your liver?

A: There is a rumor circulating on the Internet that drinking coffee can damage the liver, but research shows the opposite is true. Many early studies have found that after damaging animal livers with toxins, giving them caffeine at the same time can reduce liver inflammation and damage. The International Journal of Gastroenterology (Gastroenterology) published two American research reports, pointing out that drinking coffee can reduce the rate of abnormal liver function, and drinking more than 2 cups of coffee a day can reduce the incidence of chronic liver disease by about 60%. In 2007, a paper that comprehensively analyzed 10 related studies also pointed out that coffee drinkers have a 40% to 50% lower chance of developing liver cancer than the average person, which shows that coffee does not damage the liver.

4.How many cups of coffee is good to drink a day?

Answer: There are many different opinions on this question. It is best to trust the messages from your own body. Literature indicates that drinking 1 to 3 cups of coffee a day can dilate the heart arteries, increase blood flow, relieve migraines, promote thinking ability, improve memory, and reduce the incidence of Parkinson's disease and depression. However, many clinical studies have also pointed out that more than 500 mg of caffeine per day (about 2 cups of American coffee) can cause palpitations, sleep disorders and calcium loss. Excessive intake still has adverse effects on the body.

5.When is the best time to drink coffee during the day?

Answer: Studies have shown that for people with habitual constipation, drinking 180cc of coffee in the morning can effectively improve constipation. Generally speaking, it is better in the morning than in the afternoon. If you drink it in the afternoon, it is best not to delay it until the evening to avoid affecting your sleep. In fact, as long as it suits your personal constitution and habits, coffee is the best "refreshing drink".

6. Will drinking coffee hurt your stomach?

Answer: TV commercials keep broadcasting "Drinking coffee and eating sweets will cause you to have gastroesophageal reflux." It turns out that the problem lies in the stimulation of caffeine. In addition to secreting a large amount of gastric acid, which causes gastrointestinal discomfort, caffeine also stimulates the sphincter at the lower end of the esophagus to relax, causing "gastroesophageal reflux." Therefore, people who have stomach acid every time they drink coffee or suffer from digestive tract diseases such as gastric ulcers and duodenal ulcers should "avoid" coffee if possible. If they really want to drink it, it is best to "taste it first and stop."

7. If you are... drink less coffee!

A: Who should not drink coffee? In addition to people who are allergic to caffeine, teenagers under the age of 15 who are still in the developmental stage should not drink coffee, because the tannic acid in coffee will hinder calcium absorption, cause nervousness, and affect sleep quality; pregnant women and breastfeeding mothers are best not to drink it. If you have the habit of drinking coffee every day, limit it to one cup to avoid causing discomfort to the mother and affecting the health of the fetus. It is better for pregnant women to choose "decaffeinated beverages."

8. Can coffee also be an aphrodisiac?

Answer: Although coffee contains the same ingredient as Viagra - phosphodiesterase inhibitor, the type is different from Viagra. Its main function is to boost the spirit and make the body feel excited. It has limited effect on improving male erections. The online rumor that men drinking coffee before sexual intercourse can help regain their virility is not credible.

9.Can drinking coffee really help you lose weight?

Answer: Studies have shown that caffeine can temporarily suppress appetite, speed up the body's metabolic rate, and accelerate fat decomposition. If combined with exercise, calories are consumed faster, which helps control weight. Taking about 200 mg of caffeine one hour before exercise can promote the body's energy consumption. However, coffee is a diuretic and will accelerate dehydration of the body. You must always replenish water during exercise.

10. Can I drink coffee on an empty stomach?

Answer: Caffeine will stimulate the secretion of gastric acid. It is best not to drink it on an empty stomach. People with gastric ulcers should avoid it. It can be enjoyed leisurely with bread and other snacks. It can also stabilize nervous emotions. Drinking some boiled water at the same time can not only remove bad breath and enjoy the aroma of coffee, but also increase urine output and protect kidney function.
