How to drink coffee to prevent disease? There are four rules for drinking coffee

Nowadays, coffee is no longer strange to the Chinese. Coffee shops in the city are all over the streets; in supermarkets and in front of vending machines, there are always people who pick up a bottle of canned coffee; and white-collar workers inevitably use coffee to refresh themselves during working hours.

There is also an endless stream of research on coffee: new German research shows that drinking more coffee helps prevent hair loss in men; British dietary nutritionist Amanda? Ursula also said recently that eating too much coffee can darken the skin, and drinking coffee in the morning can also make your heart beat faster.

How to drink coffee is healthier? what are the habits of Chinese people in drinking coffee? Recently, this newspaper and Sohu Network Health Channel conducted a series of surveys.

70% of Chinese drink coffee

Of the 3234 people surveyed, 74.43% drank coffee. Among them, 7.12% of people drink more than 3 cups a day, 23.10% drink 3 cups a day, and only 26.11% say they haven't had coffee for half a year.

According to statistics, the world consumes 400 billion cups of coffee every year, and the annual sales of coffee beans are 30 billion US dollars, ranking second only to oil in the list of major commodities. Coffee is also becoming more and more popular in some tea culture countries in Asia. At present, Japan has replaced Germany as the world's second largest consumer of coffee. A survey conducted in 12 major cities in mainland China showed that 56 per cent of residents were used to drinking coffee.

Zhong Lirong, vice president of the China Coffee and Coffee Beverage Professional Committee, told Life Times that Chinese people's habit of drinking coffee has developed since the 1990s, and many urban people have even become dependent on coffee. Although the annual coffee consumption in China is only 200000 tons, the per capita consumption is increasing at a rate of 30%, which is expected to become the most potential coffee consumption country in the world.

But Zhong Lirong points out that, comparatively speaking, the proportion of Chinese people drinking pure coffee is not high. "they usually choose to add a coffee partner or drink a coffee drink directly." The survey shows that among the types of coffee preferred, 76.1% prefer instant coffee, while 6.35% usually make it themselves. In the choice of instant coffee, people mainly prefer the two major brands Nestl é (71.8%) and Maxwell (15.93%), while 7.83% do not value the brand. In addition, 53% of people drink coffee drinks occasionally. When it comes to coffee drinks, 35.43% of people first think of Nestl é, followed by Starbucks, Blue Mountain, Yaha, Wa Youyou Milk Coffee and Mengniu Milk.

How much effect does coffee have on health?

How long is the history of such a popular coffee and what effects will it have on health?

It is understood that coffee was first found in Ethiopia. So far, it has a history of at least 700 years. At that time, a shepherd found that the goat was agile after eating a kind of berry and tried to eat a little. As a result, he was refreshed. When the monks heard this, they dried the berries so that they could be transported to a distant monastery. The dried berries were the original coffee beans. Later, after the coffee beans spread to Turkey, they began to be roasted and ground with open fire, and boiled in water is the embryonic form of today's coffee.

Coffee consumption is increasing year by year, and the research on the efficacy of coffee has been paid more and more attention by the medical profession. In the past decade, there are more than 19000 studies on the composition and efficacy of coffee. Studies in Finland and the United States have found that drinking coffee from mothers may increase the risk of diabetes in babies after birth. Drinking coffee before exercise may be bad for the heart, a Swiss study has found. A survey by the National Institute of Environmental Health Sciences shows that women who drink more than one cup of coffee a day are half as likely to get pregnant as those who don't. In addition, drinking coffee may also lead to osteoporosis and increase the risk of myocardial infarction in women.

Compared with the rising skepticism, more research is aimed at rehabilitating coffee. A large number of foreign studies have shown that coffee can make people more focused. Italian studies have found that coffee protects teeth. Researchers at Harvard University in the United States recently found that drinking only one cup of coffee a day can help people avoid Alzheimer's disease. Japanese researchers point out that people who drink coffee every day for 10 years are 50% less likely to develop liver cancer than those who never drink it. In addition, studies have shown that drinking coffee can reduce the risk of gout in men and breast cancer in women.

People are a little overwhelmed by all kinds of research. The survey found that when it comes to the health effects of coffee, 59.4% of people think it can be refreshing, 14.80% think it can lose weight, and 7.2% believe that coffee can prevent Alzheimer's disease. But some people believe that coffee can lead to calcium loss (23.07%), fat drinking (21.22%), miscarriage (8.75%), high blood pressure (7.06%), dehydration (5.76%) and diabetes (5.15%).

Zhong Lirong said that coffee is indeed a double-edged sword. "the amount of caffeine in a cup of coffee we usually drink is about 50 milligrams. As caffeine has the effect of cardiotonic diuresis, it can exhilarate people's spirits and improve their brain activity. " However, it should be noted that coffee with health benefits is only freshly ground ordinary coffee, instant coffee and a variety of decaf coffee do not have these effects. "of course, drinking too much does have a bad effect on the body. Especially for Chinese people who are already deficient in calcium, they should pay attention to calcium supplements when drinking coffee. "

The "four rules" of drinking coffee

If you want coffee to promote your health, you must first learn how to drink coffee.

First, pay attention to your intake. Fan Zhihong, an associate professor at the School of Food at China Agricultural University, suggested that the total daily intake of caffeine should not exceed 250 grams, or about 2 cups. The most direct symptom of excessive drinking coffee is to cause hyperpalpitation (the heart beats violently), and even appear in a trance, walking center of gravity instability and other phenomena. If you drink four or five cups of coffee in a row, most people will feel sick.

Second, choose the right time. Fan Zhihong suggests that you try to drink it before four o'clock in the afternoon, and it's better to drink earlier. In addition, it is best not to drink before meals, otherwise it will reduce appetite and stimulate the stomach. Drinking coffee can help digestion due to increased gastric juice secretion after a meal.

Third, choose the right type of coffee. "if you drink coffee, try not to add a partner." Fan Zhihong said that coffee partners are too high in fat and contain hydrogenated vegetable oils, which is bad for health. The best way is to add whole milk, put 3 cups of coffee, pour 1 cup of milk, no sugar, taste good and healthy. Of course, black coffee is the most healthy, not only anti-oxidation, but also anti-cancer, anti-aging.

Finally, although coffee is good, it is not suitable for everyone. Fan Zhihong advises pregnant women, young people under the age of 18, who suffer from uterine fibroids, endometriosis and poor heart function not to drink or drink less. Zhong Lirong also said that coffee can make some people nervous, heartbeat faster, and even arterial embolism.
