The secrets you don't know about coffee

Many people like to drink coffee now, because the caffeine in coffee is the most notable 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 increase the sensitivity and attention of the human body, accelerate the body's metabolism, and improve the body's mental state and physical fitness.

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 has the effect of losing 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 forming gallstones.

6. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a prominent form of pollution. Indian researchers at 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 attention 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 60-65 mg 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.

Disadvantages of drinking coffee:

1. It can easily cause osteoporosis.

Caffeine easily combines with free calcium in the human body and is 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 980 elderly women aged 50 to 98 years old. The results showed that elderly women who drink more than 2 cups of coffee a day for a long time without drinking milk, regardless of their age and obesity, will have reduced bone density in the hip and spine, and the degree of reduction is related to the duration of the habit and the amount of drinking.

2. It can easily cause diabetes.

Researchers from Finland and the United States have found through investigation and analysis that these two countries consume the most coffee, and as a result, the number of people suffering from diabetes is the highest in these two countries. Among them, the Finns consume the most coffee in the world, and the country also has the most diabetics in the world. Other Nordic countries also consume a lot of coffee, and the number of people suffering from diabetes is also high. On the contrary, the Japanese consume the least coffee in the world, and the number of people suffering from diabetes 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, making the baby likely to suffer from diabetes after birth.

3. Prone to infertility.

According to a study by American scientists, women who drink a cup of coffee a 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% of them 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.
