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

Caffeine is a softer stimulant in coffee, which can improve the sensitivity, attention, metabolism, mental state and physical fitness of the human body. Usually a cup of coffee with 60-65mg caffeine. However, excessive caffeine intake is prone to tinnitus and myocardial hyperactivity (the heart beats rapidly and the pulse number increases) and the pulse is uneven, so you must drink coffee in the right amount. Here are the pros and cons of drinking coffee:

The benefits of drinking coffee:

1. Coffee contains certain nutrients. Nicotinic acid in coffee contains vitamin B, which is higher in roasted coffee beans. And there are free fatty acids, caffeine, tannic acid and so on.

two。 Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs, and has a great effect on constipation. Taking a bath with coffee powder is a kind of thermotherapy, which has the effect of losing weight.

3. Coffee has the function of relieving alcohol. Drinking coffee after drinking alcohol will quickly oxidize the acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and discharge it out of the body.

4. Coffee can relieve fatigue. In order to eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.

5. Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it stimulates gallbladder contraction and reduces cholesterol, which is prone to gallstones. The latest Harvard University researchers found that men who drank two to three cups of coffee a day were less than 40% likely to get gallstones.

6. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially the radiation of electrical appliances, has become a prominent pollution at present. Indian Barba atomic researchers have come to this conclusion in mouse experiments and say it can be applied to humans.

7. The health care and medical function of coffee. Coffee has the functions of anti-oxidation and heart protection, strengthening muscles and bones, benefiting waist and knees, appetizer, eliminating fat and accumulation, promoting orifice and dehumidification, promoting blood circulation and removing blood stasis, relieving wind and relieving spasm and so on.

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

Caffeine is a softer stimulant in coffee, which can improve the sensitivity, attention, metabolism, mental state and physical fitness of the human body. Usually a cup of coffee with 60-65mg caffeine. But excessive caffeine intake is prone to tinnitus and myocardial hyperactivity (the heart beats rapidly and the number of pulses increases). And the pulse is uneven, so you must drink the right amount of coffee.

The disadvantages of drinking coffee:

First, easy to cause osteoporosis. Caffeine is easy to combine with human free calcium and pass urine. The decrease of free calcium will inevitably lead to the decomposition of bound calcium, which leads to osteoporosis. Researchers at the University of California in the United States conducted a survey of elderly women who drank a cup of coffee instead of milk for a long time and found that regardless of age and obesity, the bone mineral density of the hip and spine decreased, and the extent of the decrease was related to the duration of the habit and the amount of consumption.

Second, it is easy to cause diabetes. Through research and analysis, researchers in Finland and the United States found that both countries are the largest consumers of coffee, resulting in the largest number of people suffering from diabetes in these two countries. Among them, Finns have the highest coffee consumption in the world, and the country has the largest number of diabetics in the world. Other Nordic countries also consume a lot of coffee and have a large number of people suffering from diabetes. On the contrary, the Japanese have the lowest coffee consumption in the world and the least people with diabetes. The researchers believe that the caffeine contained in coffee drinks can be precipitated into fetal tissue through the pancreas, especially in the fetus and brain, so that postnatal babies may develop diabetes.

Third, easy to suffer from infertility. According to research 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. Experts have investigated women who have the habit of drinking coffee, and about one of them is not easy to get pregnant. Some fertility experts believe that this is a small-scale study that cannot finally confirm the special effect of coffee on fertility. However, the researchers stressed that if it is not possible to explain the causes of infertility, it should be considered that infertility is related to caffeine.

Fourth, increase the risk of myocardial infarction. Scientists from the School of Public Health at Boston University in the United States conducted a year-long study of women who first suffered from myocardial infarction at the age of ~ and those who had never suffered from myocardial infarction. The results show that drinking a cup of coffee or more a day increases the risk of myocardial infarction by%, and the risk increases with the amount of coffee consumed.

Fifth, pregnant women drinking coffee is disadvantageous to the fetus. As early as the early 1950s, Dr. Colin of the US Food and Product Administration found in the experiment that pregnant mice would give birth to malformed mice after feeding mice the equivalent of drinking a cup of strong coffee every day. To this end, the researchers, in the name of the U. S. Food and Product Administration, warned pregnant women to stop drinking coffee.

Pregnancy induced hypertension syndrome. Pregnancy induced hypertension syndrome is a disease unique to pregnant women, the patients are now edema, hypertension and proteinuria, if not timely prevention and treatment, can endanger maternal and fetal safety. Drinking just a few cups of coffee a day can raise blood pressure, according to an Australian study. For this reason, pregnant women should not drink coffee.

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

Drinking coffee has both advantages and disadvantages. Only when we drink it reasonably can it contribute to us.
