Is it good or bad to drink coffee for a long time?

Whether long-term coffee drinking poses a threat to the human body depends on whether the amount of coffee you drink is appropriate and the type of coffee you drink .

Many friends like to drink a few cups of coffee every day, but this coffee belongs to "instant coffee" or the internet-famous coffee sold at takeaway points. If we consume too much of this kind of coffee for a long time, it may indeed have a bad effect on us, because in order to adjust the taste, higher levels of sucrose are added, and even cream and other ingredients are added to make it different. In this way, our sugar intake may exceed the standard and our intake of saturated fatty acids may also be higher.

Non-dairy creamer may also be added to instant drinks. This ingredient is contained in creamer and can increase the taste and aroma of instant drinks. However, non-dairy creamer will make us ingest "trans fatty acids". Trans fatty acids may increase the concentration of "low-density lipoprotein (LDL)" in the blood. Low-density lipoprotein will increase the circulation of cholesterol in the blood. Too much low-density lipoprotein will increase the cholesterol concentration in the blood and induce hypercholesterolemia. It may also induce a variety of cardiovascular and cerebrovascular diseases.

However, if it is ordinary black coffee, drinking it moderately every day, or adding appropriate amount of sucrose or milk, it is indeed good for the body .

Many people think that drinking coffee for a long time is not good because the caffeine content in coffee is high and they are afraid that it will affect the nerves and be bad for the body. In fact, many modern studies have found that daily moderate intake of coffee is beneficial to health. Studies have found that long-term and appropriate intake of coffee can reduce the risk of many diseases, such as common chronic diseases such as diabetes, breast cancer, prostate disease, Alzheimer's disease, Parkinson's disease, etc. As for the caffeine in coffee, as long as we drink coffee in moderation, it does not have such a big impact on the body.

Even the caffeine in coffee and green tea is not much different. Some coffees even have less caffeine than green tea. Many elderly people drink green tea every day. As for the saying of "caffeine addiction", it is also groundless. The reason for loving coffee is rarely due to the stimulation of caffeine. Instead, it is more caused by the instant coffee and Internet celebrity coffee mentioned above. Because they add high sugar, flavors, non-dairy creamer, cream and other ingredients to make coffee delicious, the more reasons are actually not as good as "sugar addiction".

Many studies have found that if adults drink 2 to 3 cups of black coffee (about 100ml) a day, it is very beneficial to the human body. However, if you drink 4 cups or more of coffee a day, it may cause side effects, such as irritating the gastrointestinal mucosa, causing gastrointestinal discomfort , dizziness and vomiting. If you do this for a long time, you may lose calcium. In addition, coffee is not suitable for children and pregnant women.
