It’s harmful! Many people now like to drink coffee, 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 relatively mild stimulant in coffee. It can improve the body's sensitivity and concentration, accelerate the body's metabolism, and improve the body's mental state and physical fitness. A typical cup of coffee contains 60-65mg of caffeine. However, excessive caffeine intake may lead to tinnitus and myocardial hyperactivity (rapid heartbeat and increased pulse rate). and uneven pulse beat, so you must drink coffee in moderation. The following are the specific pros and cons of drinking coffee:

Benefits of drinking coffee:

1. Coffee contains certain nutrients. The niacin in coffee contains vitamin B, and the content is higher in roasted coffee beans. And there are free fatty acids, caffeine, tannins, etc.

2. Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs, and is very effective in treating constipation. Taking a bath with coffee powder is a kind of warm therapy and has the effect of losing weight.

3. Coffee has the function of relieving hangover. Drinking coffee after drinking alcohol will rapidly oxidize acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and be excreted from the body.

4. Coffee can eliminate fatigue. To eliminate fatigue, it is necessary to supplement nutrition, rest and sleep, and promote metabolic function, and coffee has these functions.

5. 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 easily forms gallstones. Recently, researchers from Harvard University in the United States found that men who drink two to three cups of coffee a day have a lower than 40% chance of developing gallstones.

6. Regular drinking of coffee can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a more prominent form of pollution. Indian atomic researchers reached this conclusion in experiments on mice and said it can be applied to humans.

7. The health and medical functions of coffee. Coffee has the functions of antioxidant and heart protection, strengthening muscles and bones, benefiting the waist and knees, stimulating appetite and promoting food intake, eliminating cellulite and accumulation, promoting orifices and dehumidification, activating blood circulation and removing blood stasis, calming wind and relieving spasm.

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

Caffeine is a relatively mild stimulant in coffee. It can improve the body's sensitivity and concentration, accelerate the body's metabolism, and improve the body's mental state and physical fitness. A typical cup of coffee contains 60-65mg of caffeine. However, excessive caffeine intake may lead to tinnitus and myocardial hyperactivity (rapid heartbeat and increased pulse rate). and uneven pulse beat, so you must drink coffee in moderation.

Disadvantages of drinking coffee:

1. It can easily cause osteoporosis. Caffeine easily binds to human free calcium and is passed into the urine. The reduction of free calcium will inevitably cause the decomposition of bound calcium, leading to osteoporosis. Researchers from the University of California in the United States conducted a survey on 3-year-old elderly women. The results found that elderly women who drink a cup of coffee every day for a long time, regardless of their age and obesity level, have lower bone density in their hip and spine. It will all decrease, and the degree of decrease is related to the length of time the habit lasts and the amount of drinking.

2. It can easily cause diabetes. Researchers from Finland and the United States found through survey analysis 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, Finnish coffee consumption ranks first in the world, and the country also has the largest number of diabetics in the world. Other Nordic countries also have high coffee consumption and high numbers of people suffering from diabetes. On the contrary, the Japanese consume the least coffee in the world and have the fewest diabetics. Researchers believe that the caffeine contained in coffee drinks can pass through the pancreas and precipitate into fetal tissues, especially the fetus and brain, making babies likely to develop diabetes after birth.

3. Susceptible to infertility.

According to research by American scientists, women who drink a cup of coffee every day are more likely to suffer from infertility than women who do not drink coffee. Relevant experts have investigated 100,000 women who have the habit of drinking coffee, and about one of them has difficulty in conceiving. Some fertility experts believe that this is a small-scale study and cannot conclusively prove the special effect of coffee on fertility. However, the researchers stress that if the cause of infertility cannot be scientifically explained, caffeine-related infertility should be considered.

4. Increase the risk of myocardial infarction. Scientists from the Boston University School of Public Health conducted a 20-year study on women who suffered myocardial infarction for the first time at 2 years old and women who had never had a myocardial infarction. The results showed that drinking a cup a day or More coffee increases a woman's risk of myocardial infarction, and the risk increases with the amount of coffee consumed.

5. Pregnant women drinking coffee is harmful to the fetus. As early as the early 1990s, Dr. Cowling of the U.S. Food and Food Administration discovered in experiments that after feeding mice an amount equivalent to drinking a cup of strong coffee every day, pregnant mice would give birth to deformed mice. For this reason, researchers, in the name of the U.S. Food and Drug Administration, warn pregnant women that they should stop drinking coffee.

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

In addition, for both men and women, drinking coffee can increase the risk of heart disease and high blood pressure, and can also lead to addiction. It can be seen that for the sake of eugenics, disease prevention and health care, women should not drink coffee excessively for a long time.

Drinking coffee has advantages and disadvantages. Only if we drink it reasonably can it make a contribution to us.
