Coffee is the "necessities of life" of many people. If you don't drink it all day, there will be something wrong with you. Coffee is not only delicious and mellow, but it may even be healthy to drink in moderation. European studies have found that drinking coffee may help reduce the risk of early death and improve liver function. However, with the variety, roasting and extraction of coffee beans, the health value of coffee varies. In terms of baking, what's the difference between light baking and heavy baking if you want to drink healthily?

Spanish study: four cups of coffee a day reduces the risk of early death

There are numerous coffee-related studies, and it has been proved that the main health care effect is to reduce the risk of type 2 diabetes and cardiovascular disease. In addition, some studies have shown that drinking coffee can help reduce the risk of early death.

However, according to the Daily Mail and Science Daily websites of the United Kingdom, no studies of this type of coffee have been conducted in Mediterranean countries in the past, so a Spanish study followed nearly 20, 000 subjects between the ages of 25 and 60 for an average of 10 years and found that drinking four cups of coffee a day helped reduce the risk of early death.

The average age of the subjects at the beginning of the study was 37.7, which was quite young, so there was only a 1.7% chance of dying within 10 years. However, the researchers found that among these subjects, those who drank the most coffee had a lower risk of death.

Foreign studies have found that moderate consumption of coffee may help to reduce the risk of early death.

Moreover, drinking two more cups of coffee a day reduced the overall death rate by 22%, while among subjects over the age of 45, the subsequent death rate decreased by 30%. The downward trend in mortality is less obvious in young people, but it is significant in middle-aged people.

People who drank four cups of coffee a day had a 64% lower mortality rate than those who never drank coffee or drank little coffee. In this study, the leading cause of death was cancer, followed by heart disease. The study was presented at the European Association of Cardiology (European Society of Cardiology) meeting in Barcelona, Spain.

Coffee is a favorite drink for many people, and some of its ingredients may be helpful to your health.

Coffee contains polyphenols for antioxidation and anti-inflammation

Although these subjects are relatively young and healthy, the results of this study are consistent with other previous studies. The researchers point out that this is because the polyphenols in coffee have anti-inflammatory effects, are good for heart health and help prevent cancer. Although this study only provides data and does not directly prove that coffee drinking is the cause of the reduction in mortality, this result echoes the results of previous studies.

There are numerous studies on the health effects of coffee, but it should still be consumed in moderation in order to be healthy.

Large European study: drinking Coffee helps reduce the risk of early death

Recently, there is also a coffee-related study worthy of reference. According to data from Imperial College London (Imperial College London), the school and the International Agency for Research on Cancer (International Agency for Research on Cancer; IARC) conducted a 16-year study of about 520000 subjects over the age of 35 from 10 European countries, including the United Kingdom, France, Denmark and Italy, to explore the relationship between coffee intake and mortality.

At the end of the study, nearly 42000 subjects died, including cancer, heart failure, stroke and circulatory diseases (circulatory diseases). Finally, the study found that those who consumed the most coffee had a lower risk of all kinds of early death, especially from circulatory and digestive tract-related diseases, compared with non-coffee drinkers.

It is worth noting that coffee drinking habits vary from country to country, but similar results have been found in all 10 European countries in the study.

Coffee contains healthy substances that vary depending on the way it is roasted and made.

In addition, 14000 subjects were analyzed for biochemical metabolic indicators (metabolic biomarkers) and found that overall, coffee drinkers had better liver function and blood glucose control (glucose control) than non-coffee drinkers. This study has been published in the Annals of Internal Medicine (Annals of Internal Medicine).

Coffee contains many substances that can interact with the body, including caffeine, diterpenoids (diterpenes), antioxidants and so on, some of which have positive effects on health. However, the content of these substances varies depending on the way coffee is made.

The researchers pointed out that due to the limitations of the observational study (observational research) itself, people should not be advised to drink more or less coffee at this stage, but the study shows that the average person who drinks coffee in moderation, that is, a maximum of about three cups a day, is usually not harmful to health.

When drinking coffee, you must control the intake of caffeine in order to drink healthily.

Drinking coffee in moderation with healthy living habits

Researchers from the Spanish study said that healthy adults can drink four cups of coffee a day, which is good for their health. However, do not drink too much coffee, the European Food Safety Agency (European Food Safety Agency) pointed out that the daily intake of caffeine should not exceed 400mg.

Experts from the British Heart Foundation (British Heart Foundation) warn that the main way to reduce the risk of cardiovascular disease and early death should be to maintain a healthy lifestyle, including balanced nutrition, moderate exercise and avoiding smoking, rather than drinking coffee.

Drinking a moderate amount of coffee may be helpful to your health, but you still need to cooperate with good living habits in order to really improve your health.

Domestic dietitian Tsai Yi-Kai points out that coffee does contain chlorogenic acid, theophylline, flavonoids, trigonelline, melanoid and other substances, which have the functions of resisting oxidative pressure and lowering blood sugar. However, these effects are still being tested in vitro, and it is not clear that drinking coffee can have the same health benefits.

In recent years, there is more and more research evidence that drinking coffee can improve health, but there is no final conclusion on how much coffee to drink to achieve the health effect. Therefore, you can drink coffee in moderation. You don't have to do it just because the new study points out that you should drink a few cups a day. You should pay attention to the fact that your daily caffeine intake should not exceed 300 milligrams, and you should maintain good living habits to improve your health in an all-round way, rather than rely on coffee alone to prolong your life.

Drinking coffee should not only control the amount of caffeine consumed, but also measure whether your body is fit to drink.

Chlorogenic acid is not heat-resistant and shallow roasted coffee contains more.

On the other hand, the more frequently mentioned coffee health ingredient, chlorogenic acid, has the effect of antioxidation, but it is not heat-resistant and will decrease with the increase of roasting time and temperature of coffee beans. Dietitian Tsai Yili says that the degree of roasting of coffee varies in different regions, which can be judged by the color, aroma, and popping sound of coffee beans, but the simplest way is to distinguish them by baking time.

Generally speaking, the baking time of shallow baking is shorter, and the time of deep baking (heavy baking) is longer. When the roasting time of coffee beans is longer and the temperature is higher, the chlorogenic acid in coffee beans is more easily destroyed. Therefore, if you want to drink more chlorogenic acid, you might as well choose shallow roasted coffee.

Control the intake of refined sugar. don't drink coffee.

If you want to drink healthily, in addition to controlling your caffeine intake, you should avoid adding cream and too much refined sugar and replace it with milk, and the lactose in milk can also enhance the sweetness and make the coffee taste better. In addition, dietitian Tsai Yi-Kui warned that people suffering from digestive tract ulcers, gastroesophageal reflux, intestinal mania, and osteoporosis are not advised to drink coffee, so as not to easily stimulate the gastrointestinal tract and increase calcium loss.
