Is a cup of instant coffee a day good for you? Here comes some popular science knowledge

Coffee is a common drink in our daily life, but there are different opinions on whether it is good or bad. Most people think that drinking coffee regularly is not good because the caffeine in it may affect the nerves, and long-term coffee drinking is not good for the body. However, modern research has found that in fact, daily moderate coffee intake may be beneficial to health. It is a healthy drink, which is the discovery of continuous scientific research in various countries.

Coffee contains some polyphenol compounds, the main component of which is chlorogenic acid, which is essentially a hydroxycinnamic acid. This substance has a certain antioxidant effect. If you drink coffee in moderation regularly, it can have a proper free radical scavenging effect and has a good effect on the body.

It also has a positive effect on intestinal microorganisms:

Moderate coffee intake can improve the intestinal microbial environment, thereby improving the types, distribution and corresponding content of host bacteria, such as the bifidobacteria you are familiar with, thereby improving the intestinal environment and playing a positive role; it also has a positive effect on improving the body's anti-inflammatory ability.

For example, Giuseppe Grosso recently introduced a paper on coffee. The paper introduced a study and analysis of coffee by 127 groups across the country, and finally concluded that long-term coffee drinking may reduce the risk of many diseases, such as diabetes, prostate disease, breast cancer, stroke, Parkinson's disease and other diseases that are common in our lives. Many people still have opinions about the caffeine in coffee. In fact, the caffeine content in coffee may be much lower than that in green tea. The caffeine content in green tea leaves is about 3.5%, while the caffeine content in coffee beans such as "Aracapi" and "Robusta" is only about 1~2%. We can drink green tea regularly, so why can't we accept drinking coffee regularly? However, it should be noted that coffee is a refreshing drink after all. It is best to drink it during the day and avoid drinking it before going to bed, especially for people who are sensitive to coffee.

More academic studies have found that if adults drink 2 to 3 cups (about 500ML) of coffee a day, the benefits outweigh the harm. However, long-term intake of large amounts of coffee may cause "coffee syndrome", such as mental tension, anxiety, muscle tension, insomnia and other symptoms. This is because excessive caffeine affects the nerve center.

Here are some things you need to know about drinking coffee:

Drinking coffee the right way can make you healthier:

First of all, coffee is drinkable, but you must choose reliable coffee. It is recommended that you choose the right coffee. What is the right coffee? It means coffee that retains the nutrients of coffee. "Vilavie" cold brew coffee is extracted from coffee beans after extracting coffee concentrate, and then vacuum-frozen at -40℃. Ultra-low temperature freezing can perfectly preserve the flavor and taste of coffee, and can also lock in the nutrients of coffee itself, so that the coffee produced is rich in aroma and pure in taste.

When drinking coffee, please pay attention to the "limit":

Many people regard drinking coffee as a hobby, and some people even drink 10 cups a day. But in fact, drinking too much coffee will undoubtedly add a greater burden to the kidneys. The daily caffeine intake is not recommended to exceed 250 mg; it is recommended that the daily consumption of coffee should not exceed 5 cups.

When drinking coffee, it is not recommended to add too much sugar:

Coffee is very bitter, so many people choose to add too much sugar; however, excessive intake of sugar substances will increase the probability of suffering from diseases such as dental caries, obesity, and diabetes; therefore, if you think coffee is too bitter, you can choose to add some pure milk and refuse to add creamer or refined sugar.

Some people do not recommend drinking coffee:

Children and adolescents:

All parts of the body of this group of people are in the development stage, and they are also in a stage of high-intensity learning. Caffeine intake can easily affect their sleep and brain work; so it is best for them not to drink coffee, and if they do drink it, it must be limited.

Pregnant women:

It cannot be said that pregnant women cannot drink coffee. Such statements are rumors. Specifically, it is not recommended for pregnant women to consume large amounts of caffeine. During the pregnancy and delivery period, you should try not to eat foods containing caffeine. If you drink coffee, please do not exceed 2 cups a day.
