The pros and cons of drinking coffee

Many people like to drink coffee now, because the caffeine in coffee is the most noticeable of all the ingredients in coffee. The biggest characteristic of coffee flavor - bitterness, is caused by caffeine.

Caffeine is a mild stimulant in coffee. It can increase the sensitivity and concentration of the human body, accelerate the metabolism of the human body, and improve the mental state and physical fitness of the human body. Usually, a cup of coffee contains 60-65mg of caffeine. However, consuming too much caffeine can easily cause tinnitus, myocardial hyperactivity (rapid heartbeat, increased pulse rate), and uneven pulse, so coffee must be consumed in moderation. The following are the specific advantages and disadvantages of drinking coffee:

Benefits of drinking coffee:

1. Coffee contains certain nutrients. The nicotinic acid in coffee contains vitamin B, and the content is higher in roasted coffee beans. It also contains free fatty acids, caffeine, tannic acid, etc.

2. Coffee is good for the skin. Coffee can promote metabolism, activate digestive organs, and has a great effect on constipation. Taking a bath with coffee powder is a warm therapy that helps lose weight.

3. Coffee can help you sober up. Drinking coffee after drinking alcohol will cause the acetaldehyde converted from alcohol to be rapidly oxidized, decomposed into water and carbon dioxide and excreted from the body.

4. Coffee can eliminate fatigue. To eliminate fatigue, you must supplement nutrition, rest and sleep, and promote metabolic function, and coffee has these functions.

5. Drinking three cups of coffee a day can prevent gallstones. Caffeinated coffee can stimulate the contraction of the gallbladder and reduce the cholesterol in the bile that is prone to form gallstones. The latest research from Harvard University in the United States shows that drinking three cups of coffee a day can reduce the risk of gallstones by 40%.

6. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a prominent form of pollution. Indian researchers from the Bhabha Atomic Energy Institute came to this conclusion in a mouse experiment and said it can be applied to humans.

7. Coffee's health and medical functions: Coffee has the functions of anti-oxidation, protecting the heart, strengthening the tendons and bones, benefiting the waist and knees, stimulating appetite, eliminating fat and stagnation, benefiting the orifices and removing dampness, promoting blood circulation and removing blood stasis, and calming wind and stopping spasms.

8. The influence of coffee on mood. Experiments show that if an average person absorbs 300 mg (about 3 cups of brewed coffee) of caffeine a day, it will have a good effect on a person's alertness and mood.

Caffeine is a mild stimulant in coffee. It can increase the sensitivity and concentration of the human body, accelerate the metabolism of the human body, and improve the mental state and physical fitness of the human body. Usually, a cup of coffee contains 60-65mg of caffeine. However, consuming too much caffeine can easily cause tinnitus, hypertrophy of the heart muscle (rapid heartbeat, increased pulse rate), and uneven pulse. Therefore, coffee must be consumed in moderation.

Disadvantages of drinking coffee:

1. It can easily cause osteoporosis. Caffeine can easily combine with free calcium in the human body and be excreted through urine. The reduction of free calcium will inevitably lead to the decomposition of bound calcium, thus leading to osteoporosis. Researchers from the University of California, USA, conducted a survey on elderly women aged 15 to 20 years old. The results showed that elderly women who drink a cup of coffee every day for a long time instead of milk, regardless of their age and obesity, will have reduced bone density in their hips and spines, and the degree of reduction is related to the duration of the habit and the amount of drinking.

Second, it can easily cause diabetes. Through investigation and analysis, researchers from Finland and the United States found that these two countries are the countries that consume the most coffee. As a result, the number of people suffering from diabetes in these two countries is also the highest. Among them, the coffee consumption of Finns ranks first in the world, and the country also has the largest number of diabetics in the world. The coffee consumption of other Nordic countries is also high, and the number of people suffering from diabetes is also high. On the contrary, the coffee consumption of Japanese people is the lowest in the world, and the number of diabetics is also the lowest. Researchers believe that the caffeine contained in coffee drinks can pass through the pancreas and precipitate into the fetal tissue, especially the fetal brain, which may cause diabetes in babies after birth.

3. Prone to infertility. According to a study by American scientists, women who drink a cup of coffee every day are more likely to suffer from infertility than those who do not drink coffee. Relevant experts have investigated women who have the habit of drinking coffee, and about 10,000 women are not easy to conceive. Some fertility experts also believe that this is a small-scale study and cannot finally confirm the special effect of coffee on fertility. However, researchers emphasize that if the cause of infertility cannot be explained by science, it should be considered that infertility is related to caffeine.

4. Increase the risk of myocardial infarction. Scientists from the School of Public Health at Boston University in the United States conducted a 20-year study on 18 women who suffered their first myocardial infarction between the ages of 40 and 59 and 13 women who had never suffered a myocardial infarction. The results showed that drinking one cup or more of coffee a day can increase women's risk of myocardial infarction by 10%, and the risk increases with the amount of coffee consumed.

5. Pregnant women drinking coffee is harmful to the fetus. In the early 1990s, Dr. Colin of the U.S. Food and Drug Administration found in an experiment that if pregnant mice were fed an amount equivalent to a cup of strong coffee every day, they would give birth to deformed mice. For this reason, the researcher warned pregnant women in the name of the U.S. Food and Drug Administration: Stop drinking coffee.

6. Pregnancy-induced hypertension syndrome. Pregnancy-induced hypertension syndrome is a disease unique to pregnant women. Patients present with edema, hypertension and proteinuria. If not treated in time, it may endanger the safety of the mother and the fetus. According to an Australian study, drinking only a few cups of coffee a day will increase blood pressure. For this reason, pregnant women should not drink coffee.

In addition, regardless of gender, drinking coffee can increase the risk of heart disease and high blood pressure, and can also lead to addiction. Therefore, for the sake of eugenics and disease prevention and health care, women should not drink coffee for a long time or in excess.

Drinking coffee has its pros and cons, and only if we drink it reasonably can it contribute to our health.
