After drinking coffee, your heart beats faster. Does it protect blood vessels or damage the heart? tell you the truth

Wang Kai (pseudonym) is an executive of a listed company. He often needs to socialize with customers, and he can't avoid drinking. Later, he heard that coffee can protect the liver, so he slowly developed the habit of 2 cups of coffee a day .

Some time ago, the company arranged a physical examination, Wang Kai's transaminase was elevated, and the physical examination report was diagnosed as fatty liver .

Wang Kai was very puzzled, didn't he say that coffee protects the liver? I drank so much coffee, how could I still get liver disease in the end? Could it be that coffee doesn't actually protect the liver, but actually hurts the liver?

1. Does coffee nourish the liver or damage the liver? Research finds answers

Coffee is one of the most widely consumed beverages in the world, and there is not a lot of research on the relationship between coffee and health. If chronic liver disease has become a global health problem, does coffee nourish or damage the liver?

In a study on the association between coffee and chronic liver disease published in the international journal BMC, scientists from the University of Southampton and other institutions analyzed data from 495,585 people who regularly drink coffee from the UK Biobank.

Through an average of 10.7 years of follow-up survey, the results found: compared with people who do not drink coffee, consumption of any type of coffee will reduce the risk of chronic liver disease by 21% , chronic or fatty liver disease risk will be reduced by 20%, and death due to chronic liver disease The risk was reduced by 49%, and 3-4 cups of coffee a day was the best benefit.

The researchers say coffee contains high levels of kahweol and cafestol, both of which have been shown to be effective against chronic liver disease in animals.

So why does Wang Kai suffer from fatty liver again? In fact, this is inseparable from his frequent work and entertainment, long-term drinking, and big fish . Even drinking coffee cannot counteract the "side effects" of a poor lifestyle.

Second, after drinking coffee, the heart beats faster, is it harmful to the heart?

Many people may experience rapid heartbeat after drinking a large cup of coffee. Does this mean that it is harmful to the heart?

This is actually a normal phenomenon, which is related to the individual's sensitivity to caffeine . Some people may be more sensitive to caffeine and metabolize caffeine at a slower rate, which will cause discomfort such as rapid heartbeat and dizziness.

For those who drink coffee for a long time, what benefits may the body reap?

1. Reduce the risk of gout

A joint team from Japan's Defense Medical University and Osaka University released a new study that conducted the first Mendelian randomization (MR) analysis of coffee- drinking hyperuricemia and gout patients and found that: Coffee reduces the risk of gout by 25% .

However, for gout patients, if they don’t like coffee, they can also choose dairy products. Studies have shown that dairy products can also effectively reduce the incidence of gout . In addition, drink less alcoholic beverages, sugar-sweetened beverages and other beverages, the more you drink, the higher the risk of gout.

2. Reduce the risk of diabetes

The "Food and Health-Scientific Evidence Consensus" of the Chinese Nutrition Society pointed out that 1-2 cups of American coffee a day can reduce the risk of diabetes. But be careful not to consume too much added sugar in your coffee.

3. Prevent heart disease

Multiple long-term meta-analyses of coffee have shown that coffee drinking is inversely associated with the risk of death from cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke. Drinking a moderate amount of coffee every day may reduce the risk of cardiovascular disease.

3. Is coffee with added sugar still healthy? 3 types of people drink less

Coffee without added sugar or milk will feel more bitter and unsatisfactory to some people's tastes, but there are also claims that coffee with added sugar may lose its health benefits. Is sweetened coffee really unhealthy?

Recently, Mao Chen's team from Southern Medical University published a related study on the relationship between unsweetened, sweetened and artificially sweetened coffee and all-cause mortality and cause-specific mortality in the journal Annals of Internal Medicine.

The analysis found that people who drank moderate amounts of unsweetened coffee were 16%-21% less likely to die compared with people who didn't drink coffee; and those who drank an average of 1.5-3.5 cups of sugar-sweetened coffee per day were less likely to die than those who didn't drink coffee. The odds of dying were 29% to 31% lower.

Thus, coffee drinking was associated with a lower risk of death in betta fish, regardless of whether sugar was added.

However, it should be emphasized that drinking coffee needs to have a "degree". The current widely accepted recommendation in the nutrition and medical community is that healthy adults drink two or three cups a day, and the benefits outweigh the risks.

It is recommended to drink coffee after breakfast and lunch, not on an empty stomach or after dinner, so as not to affect digestion and sleep.

In addition, special populations are advised to drink less coffee, including:

• Hypertensive patients: avoid rapid rise in blood pressure;
• Pregnant women: Excessive caffeine intake can affect catecholamine levels in the blood of pregnant women and fetuses;
• Children and adolescents: in the growth and development period, it is best not to drink coffee.

Of course, if you don’t have the habit of drinking coffee, or you feel uncomfortable after drinking coffee, you don’t have to force yourself to drink it deliberately. Drinking coffee in moderation does have benefits for the human body, but these benefits can also be obtained from other foods, not necessarily coffee.
