The advantages and disadvantages of drinking coffee

The benefits of 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.

The disadvantages of coffee:

1. Make a mess when you are nervous

Caffeine helps to improve alertness, agility, memory and concentration. But drinking more coffee than you are used to will produce the same dose of stimulants that you are used to, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus.

two。 Aggravate hypertension

Caffeine is often combined with other simple painkillers because of its analgesic effect, but if you take it in large quantities for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, coupled with emotional stress, it can have a dangerous multiplication effect, so people at risk of high blood pressure should especially avoid drinking caffeinated drinks during stressful times at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. One study shows that blood pressure can rise for up to 12 hours after drinking a cup of coffee.

3. Induce osteoporosis

Caffeine itself has a good diuretic effect, if you drink a lot of coffee for a long time, it is easy to cause bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis for women. But the premise is that people who don't get enough calcium in normal food, or people who don't move very often, plus women after menopause, calcium loss caused by lack of estrogen, coupled with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still stop eating for fear of choking.

In addition, the following six types of people are not suitable for drinking coffee:

Suffering from high blood pressure, coronary heart disease, arteriosclerosis and other diseases-long-term or heavy consumption of coffee can cause cardiovascular disease.

Older women-Coffee reduces calcium and causes osteoporosis. After menopause, women need to add ten times the amount of calcium every day.

People with stomach problems-drinking too much coffee can worsen stomach problems.

Pregnant women-drinking too much coffee can lead to fetal malformation or miscarriage.

People with vitamin B1 deficiency-vitamin B1 can maintain the balance and stability of the nervous system, and coffee has a destructive effect on it.

Cancer patients-drinking too much coffee is at risk of cancer to normal people.

Drinking more coffee is bad for women's health:

1. Prone to infertility researchers have found that women who drink one cup of coffee a day are more likely to suffer from infertility than those who do not drink coffee. Experts have investigated 104 women who have the habit of drinking coffee, of which about 50 are not easy to get pregnant. Although this is a small-scale study, it cannot finally confirm the special effect of coffee on fertility. However, the researchers believe that if the cause of infertility cannot be found medically, it should be considered that infertility may be related to caffeine.

2. increase the risk of myocardial infarction medical experts in the United States studied 858 women who first suffered from myocardial infarction between the ages of 45 and 69 and 858 women who had never suffered from myocardial infarction for a period of 4 years. The results showed that drinking five or more cups of coffee a day increased women's risk of myocardial infarction by 70%, and the risk increased with the amount of coffee consumed.

3. Osteoporosis researchers investigated 980 elderly women aged 50-98 years old. The results showed that the bone mineral density of hip and spine decreased in elderly women who drank more than 2 cups of coffee without milk for a long time, regardless of age and degree of obesity, and the degree of decrease was related to the duration of coffee drinking habit and the amount of drinking. Because caffeine can be combined with free calcium in the human body and excreted through urine. The decrease of free calcium will inevitably lead to the decomposition of bound calcium, which leads to osteoporosis.

4. Coffee drinking by pregnant women is harmful to the fetus as early as in the early 1980s, experts from the United States Food and Drug Administration found in the experiment that when mice were fed with 12-24 cups of espresso for adults every day, pregnant mice would give birth to malformed mice. To this end, the researchers, in the name of the U. S. Food and Drug Administration, warned pregnant women to stop drinking coffee.

5. Aggravating pregnancy induced hypertension syndrome is a disease unique to pregnant women, which is characterized by edema, hypertension and albuminuria. If not timely prevention and treatment, it can endanger the safety of pregnant women and fetuses. 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 to avoid aggravating the condition of pregnancy induced hypertension syndrome.

6. Researchers in Finland and the United States, which are prone to diabetes, have found that both countries consume the most coffee. As a result, the two countries also have the largest number of people with diabetes. Among them, Finns have the largest coffee consumption in the world, and the country has the largest number of people with diabetes 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 fetal liver and brain, so that postnatal babies may develop diabetes.

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.
