Analysis of the advantages and disadvantages of drinking coffee

The word "coffee" originated from a small town called Kaffa in Ethiopia. In Greek, "Kaweh" means "strength and passion". Tea, coffee and cocoa are known as the three major beverages in the world. Today, Nutrition and Health will take you to understand the advantages and disadvantages of drinking coffee. Interested friends may wish to learn together!

1. 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 helps lose weight.

3. Coffee can eliminate fatigue. To eliminate fatigue, you must supplement nutrition, rest and sleep, and promote metabolic function, and coffee has these functions.

4. 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. The latest research from Harvard University in the United States found that men who drink two to three cups of coffee a day have a 40% lower chance of getting gallstones.

5. Drinking coffee regularly can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a prominent form of pollution. Indian researchers from the Bhabha Atomic Energy Institute came to this conclusion in a mouse experiment and said it can be applied to humans.

6. 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.

7. 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.

2. Taboos of drinking coffee

1. Remember that coffee should not be taken with tea. The tannic acid in tea and coffee can reduce the absorption of iron by 75%. It is better to take it with warm water;

2. The tannic acid in tea and coffee will reduce calcium absorption. Therefore, it is best to drink tea and coffee between meals;

3. If pregnant women drink a lot of caffeinated beverages and foods, they will experience symptoms such as nausea, vomiting, headache, and increased heart rate. Caffeine can also enter the fetus through the placenta and affect fetal development;

4. Many doctors believe that if pregnant women drink 1-2 cups (6-8 ounces per cup) of coffee, tea or carbonated drinks every day, it will not affect the fetus. However, for the sake of caution, pregnant women are advised not to drink caffeine. Caffeine can lead to an increase in the rate of miscarriage, so they should drink decaffeinated beverages;

5. Children should not drink coffee. Caffeine can excite children's central nervous system, interfere with their memory, and cause ADHD.

6. Strong tea, coffee, and carbonate-containing beverages are also risk factors for gastrointestinal ulcers; therefore, patients with stomach diseases should not drink too much coffee.

7. Coffee drinks contain caffeine, so they can easily cause tinnitus.

8. It makes things worse when you are nervous. Caffeine helps to improve alertness, sensitivity, memory and concentration. But drinking more coffee than you are used to will produce the same effect as taking the same dose of stimulants, which will cause nervousness. For people prone to anxiety disorders, caffeine will make symptoms such as sweaty palms, palpitations and tinnitus worse. Because drinking coffee can make people excited, people with insomnia should not drink coffee.

9. Aggravates high blood pressure. Caffeine is often combined with other simple analgesics because of its analgesic effect. However, long-term and large-scale use, if you already have high blood pressure, will only make your condition worse. Because caffeine alone can increase blood pressure, if it is combined with emotional tension, it will have a dangerous multiplication effect. Therefore, people at risk of high blood pressure should especially avoid drinking caffeinated beverages when they are under great work pressure. Some people who have the habit of drinking coffee all year round think that they are immune to the effects of caffeine, but this is not the case. A study shows that after drinking a cup of coffee, blood pressure can rise for up to 12 hours;

11. Inducing osteoporosis Caffeine itself has a good diuretic effect. If you drink coffee for a long time and in large quantities, it is easy to cause bone loss, which will have an adverse effect on the preservation of bone mass. For women, it may increase the threat of osteoporosis. But the premise is that you don’t have enough calcium in your food, or you don’t exercise often, and women after menopause lose calcium due to lack of estrogen. These conditions plus a large amount of caffeine may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still avoid giving up because of fear.

3. The disadvantages of excessive coffee drinking

In the case of long-term intake, large doses of caffeine are a drug that can lead to "caffeine poisoning". Caffeine poisoning includes addiction and a series of physical and psychological adverse reactions, such as nervousness, irritability, anxiety, tremors, muscle twitches (hyperreflexia), insomnia and palpitations. (The average person takes caffeine because of its stimulating effect. Many students take caffeine pills when preparing for exams and those who work night shifts. Under the strict definition of addiction, only gradually increasing dosage is addiction, and caffeine dependence is more appropriate. However, under a widely accepted definition, all chronic and difficult to get rid of behaviors are called addiction, so caffeine addiction can also be described.) In addition, because caffeine can increase stomach acid, continued high-dose intake can lead to peptic ulcers, erosive esophagitis and gastroesophageal reflux disease. However, because both regular and decaffeinated coffee irritate the gastric mucosa and increase gastric acid secretion, caffeine may not be the only ingredient in coffee.

Four caffeine-induced psychiatric disorders confirmed by the Diagnostic and Statistical Manual of Mental Disorders (4th edition) include caffeine overexcitation, caffeine anxiety disorder, caffeine sleep disorder and other caffeine-related disorders.
