1. Coffee contains some nutrients. Nicotinic acid in coffee contains vitamin B, and roasted coffee beans have higher content. But also free fatty acids, caffeine, tannic acid and so on.
2. Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs and play a great role in constipation. Bathing with coffee powder is a kind of hyperthermia, which has the function of losing weight.
3. Coffee has the function of relieving alcoholism. Drinking coffee after drinking will quickly oxidize acetaldehyde converted by alcohol, decompose it into water and carbon dioxide and excrete it.
4. Coffee can relieve fatigue. To eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.
Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it can stimulate gallbladder contraction and reduce cholesterol which is easy to form gallstones in bile. Recently, researchers at Harvard University found that men who drink two or three cups of coffee a day have a lower risk of gallstones than 40%.
6. Drinking coffee regularly can prevent radiation injury. Radiation hazards, especially electrical radiation, have become the prominent pollution at present. Baba's Indian atomic researchers reached this conclusion in mouse experiments and said it can be applied to humans.
7. The health function of coffee. Coffee has the functions of resisting oxidation, protecting the heart, strengthening bones and muscles, benefiting the waist and knees, stimulating appetite, promoting eating, reducing fat and digestion, inducing resuscitation and removing dampness, promoting 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 (about 3 cups of brewed coffee) every day, which will have a good influence on a person's alertness and mood.
Caffeine is a mild stimulant in coffee, which can improve human sensitivity and attention, accelerate human metabolism, and improve human mental state and physical quality. Usually a cup of coffee contains 60-65 milligrams of caffeine. However, if you consume too much caffeine, you are prone to tinnitus and myocardial hyperfunction (the heart beats faster and the pulse frequency increases). And the pulse is uneven, so be sure to drink coffee in moderation.
The disadvantages of drinking coffee:
First, it is easy to cause osteoporosis. Caffeine is easily combined with human free calcium and excreted through urine. The decrease of free calcium will inevitably lead to the decomposition of bound calcium, which will lead to osteoporosis. Researchers at the University of California, USA, conducted a survey of elderly women aged from 18 to 18. The results show that the bone mineral density of hip and spine of elderly women who drink coffee instead of milk for a long time every day will decrease regardless of their age and obesity, and the degree of decline is related to the habit duration and drinking amount.
Second, it is easy to cause diabetes. Through investigation and analysis, researchers in Finland and the United States found that coffee consumption in these two countries is the largest, so the number of people suffering from diabetes in these two countries is also the largest. Among them, Finland's coffee consumption ranks first in the world, and the country has the largest number of diabetic patients in the world. Other Nordic countries also drink a lot of coffee and suffer from diabetes. On the contrary, Japanese people drink the least coffee in the world and have the least number of people with diabetes. Researchers believe that caffeine contained in coffee drinks can be precipitated into fetal tissues through the pancreas, especially in the fetus and brain, which may cause diabetes after birth.
Third, it is easy to suffer from infertility. American scientists say that women who drink a cup of coffee every day are more likely to suffer from infertility than women who don't drink coffee. Experts investigated 100 women who have the habit of drinking coffee, and about 100 women are not easy to get pregnant. Some fertility experts believe that this is a small-scale study and cannot finally confirm the special role of coffee in fertility. However, the researchers stressed that if the cause of infertility cannot be explained scientifically, it should be considered that infertility is related to caffeine.
Fourth, increase the risk of myocardial infarction. Scientists from the School of Public Health of Boston University in the United States conducted a one-year study on women who suffered from myocardial infarction for the first time and women who had never suffered from myocardial infarction. The results show that drinking 10 or more cups of coffee every day will increase the risk of myocardial infarction in women by 10%, and the risk will increase with the increase of coffee consumption.
Five, pregnant women drinking coffee is not good for the fetus. As early as the early 1990s, Dr. Colin of the US Food and Drug Administration found in experiments that pregnant mice would give birth to deformed mice after feeding them the amount equivalent to drinking ~ cups of espresso every day. To this end, the researchers warned pregnant women in the name of the US Food and Drug Administration that they should stop drinking coffee.
Sixth, pregnancy-induced hypertension syndrome. Pregnancy-induced hypertension syndrome (PIH) is a unique disease of pregnant women. The patients are edema, hypertension and proteinuria, which may endanger the safety of mother and baby if not prevented in time. According to an Australian study, drinking only a few cups of coffee a day will raise blood pressure. Therefore, pregnant women should not drink coffee.
In addition, drinking coffee will increase the risk of heart disease and high blood pressure for men and women, and it will also lead to addiction. It can be seen that women should not drink too much coffee for a long time for eugenics, disease prevention and health care.
