The eight most common misunderstandings about coffee

I think many friends of the older generation will be a little biased in their interpretation of coffee, thinking that drinking coffee is not good for their health, even harmful. The following editor aims at several coffee misunderstandings that are easy to produce in ordinary times to scientifically refute rumors.

[misunderstanding 1 Coffee can cause insomnia] most people drinking coffee six hours before going to bed will not affect sleep. However, based on the different metabolism of each person, the sensitivity is also different, the amount of coffee drunk is different, the impact is also different. After drinking coffee, people who are too sensitive will not only have insomnia, but also have nervousness and gastrointestinal discomfort.

[myth 2: women who want to get pregnant should not drink coffee] studies have shown that a small amount of coffee has nothing to do with pregnancy, miscarriage, birth defects, premature delivery and low birth rates. However, for women who are pregnant or plan to become pregnant, it is best not to consume more than 200 milligrams of caffeine a day, as large amounts of caffeine can lead to miscarriage.

Misunderstanding 3. There is some truth to the saying that coffee can be addictive, but it depends on your understanding of addiction. For the central nervous system, coffee is an irritant, often drink coffee, the body can have a slight dependence on it. But coffee is not as harmful to physical and mental health as other addictive drugs. But if you suddenly stop drinking coffee, you may have symptoms such as headaches, fatigue, anxiety, irritability, depression and lack of concentration, but these symptoms only last for a few days.

Misunderstanding 4. Coffee can increase the risk of osteoporosis, heart disease and cancer.] generally speaking, 300 milligrams of caffeine or three cups of coffee a day are harmless to health. But the situation may be different for sensitive people, such as patients with high blood pressure or the elderly.

[myth 5: coffee is harmful to children] surveys show that it is safe for children between the ages of 6 and 9 to eat 22 milligrams of coffee a day. But many children are sensitive to coffee and have temporary anxiety or irritability. And most of the caffeine consumed by children comes from carbonated drinks, energy drinks or sweetened tea. These drinks are rich in sugar, which can lead to obesity in children. So, even if caffeine is harmless, coffee drinks are not good for children.

[myth 6: coffee wakes people up] people stubbornly think that coffee wakes people up, so they drink coffee with wine, but it turns out that their reaction time and judgment are reduced. Research shows that college students who drink alcohol and coffee at the same time are more likely to have car accidents.

[myth 7: coffee has dehydration] Coffee will give you the urge to urinate, but the loss will be made up for. Although coffee acts as a mild diuretic, studies have shown that coffee does not cause dehydration.

And the anti-inflammatory effect of coffee will strengthen the immune function and relieve allergic reactions. Other studies have shown that coffee can reduce the prevalence of Alzheimer's disease, liver disease, intestinal disease and type 2 diabetes. But remember not to eat too much caffeine.
