What are the benefits and drawbacks of regularly drinking coffee?
Abstract
The relationship between coffee and human health centers on the component caffeine. It can stimulate the central nervous system and muscles, thereby improving alertness, enhancing thinking ability, and relieving muscle fatigue. In terms of the cardiovascular system, caffeine helps improve the heart's operating efficiency, dilates blood vessels, and speeds up blood flow. As for the digestive system, it can assist the digestive process and promote the breakdown of fat.
Before discussing the pros and cons of drinking coffee, it is worth first understanding what main substances coffee actually contains.
Caffeine: It has a distinctly bitter taste and can excite the central nervous system, heart, and respiratory system. Moderate caffeine intake can also relieve muscle fatigue and stimulate the secretion of digestive juices. At the same time, it can enhance kidney function, have a diuretic effect, and help the body excrete excess sodium ions. However, once intake is excessive, it may cause caffeine poisoning.
Coffee
Tannic acid: After boiling, tannic acid decomposes into pyrogallic acid, which is also the reason coffee tastes worse after being brewed for too long.
Fat: The fat in coffee mainly consists of acidic fat and volatile fat.
Acidic fat: Refers to the acidic substances contained in fat, whose intensity varies depending on the coffee bean variety.
Volatile fat: This is the core source of coffee's aroma and can release about forty aromatic components.
Protein: It is a major source of calories, but its proportion in coffee is not high. Most of the protein in coffee grounds does not dissolve into the coffee liquid during extraction, so the actual intake is very limited.
Sugar: The sugar content of raw coffee beans is about 8%. After roasting, most of the sugar converts into caramel, giving coffee its brown color and combining with tannic acid to produce sweetness.
Fiber: The fiber in raw beans carbonizes after roasting and combines with caramel, jointly shaping coffee's color.
Minerals: Coffee contains small amounts of lime, iron, phosphorus, sodium carbonate, and so on.
The benefits and drawbacks of drinking coffee: first, let's look at the benefits
1. Coffee has certain nutritional value. The niacin in coffee contains vitamin B, and roasted coffee beans have a higher vitamin B content. It also contains free fatty acids, caffeine, tannic acid, and other components.
2. Coffee is good for the skin. It can accelerate metabolic function and activate the digestive organs, with a notable effect on relieving constipation. Bathing with coffee powder is a thermotherapy that helps with weight loss.
3. Coffee can help sober you up. Drinking coffee after alcohol consumption can promote the rapid oxidation of acetaldehyde converted from alcohol, breaking it down into water and carbon dioxide for excretion from the body.
4. Coffee helps eliminate fatigue. To relieve fatigue, it is necessary to supplement nutrition, ensure rest and sleep, and promote metabolism, and coffee happens to perform these functions.
5. Three cups of coffee a day can prevent gallstones. Caffeinated coffee can stimulate gallbladder contraction and reduce the cholesterol content in bile that easily forms gallstones. The latest research from Harvard University in the United States shows that men who drink two to three cups of coffee daily have a probability of developing gallstones lower than 40%.
6. Regularly drinking coffee can reduce radiation damage. Radiation damage such as electrical appliance radiation has become a relatively prominent pollution issue at present. Researchers at India's Bhabha Atomic Research Centre reached this conclusion through mouse experiments and stated that the results can be extrapolated to humans.
7. Coffee has health care and medical benefits. It can resist oxidation, protect the heart, strengthen muscles and bones, benefit the waist and knees, stimulate appetite and promote eating, reduce fat and resolve food accumulation, open the orifices and remove dampness, invigorate blood and resolve stasis, calm wind and stop spasms, and so on.
8. Coffee affects mood. Experiments show that ordinary people's daily intake of 300 milligrams of caffeine (about 3 cups of brewed coffee) has a positive effect on alertness and emotional state.
The benefits and drawbacks of drinking coffee: excessive use brings many drawbacks
If caffeine is consumed in large amounts over the long term, it takes on drug-like properties and may lead to "caffeine poisoning." Caffeine poisoning includes addiction as well as a series of adverse physical and psychological reactions, such as nervousness, irritability, anxiety, tremors, muscle twitching (hyperreflexia), insomnia, and palpitations. Most people take caffeine for its stimulant effects, and many students take caffeine tablets when preparing for exams or working night shifts. Addiction in the strict sense requires continuously escalating doses, so "caffeine dependence" is a more accurate description; however, under a widely accepted definition, all chronic and difficult-to-quit behaviors can be called addiction, so describing it as caffeine addiction also makes sense. In addition, caffeine promotes increased gastric acid, and sustained high-dose intake may induce peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease. However, both regular coffee and decaf coffee stimulate the gastric mucosa and increase gastric acid secretion, so caffeine may not be the only disease-causing component in coffee.
The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) identifies four types of mental disorders caused by caffeine: caffeine intoxication, caffeine-induced anxiety disorder, caffeine-induced sleep disorder, and other caffeine-related disorders.
The benefits and drawbacks of drinking coffee: summarized as follows
1. Coffee contains certain nutritional components. The niacin in coffee contains vitamin B, and roasted coffee beans have a higher content. It also has free fatty acids, caffeine, tannic acid, and so on.
2. Coffee is beneficial to the skin. Coffee can promote metabolic function, activate the digestive organs, and has a great effect on constipation. Bathing with coffee powder is a thermotherapy with a weight-loss effect. Drinking a cup of coffee after a meal also helps digestion.
3. Coffee has a sobering function. Drinking coffee after alcohol consumption will cause acetaldehyde converted from alcohol to oxidize rapidly, decompose into water and carbon dioxide, and be excreted from the body.
4. Coffee can eliminate fatigue. To eliminate fatigue, it is necessary to supplement nutrition, rest and sleep, and promote metabolic function, and coffee has these functions.
5. Three cups of coffee a day can prevent gallstones. Caffeinated coffee can stimulate gallbladder contraction and reduce the cholesterol in bile that easily forms gallstones. The latest discovery by researchers at Harvard University in the United States is that men who drink two to three cups of coffee a day have a probability of developing gallstones lower than 40%.
6. Regularly drinking coffee can prevent radiation damage. Radiation damage, especially radiation from electrical appliances, has become a relatively prominent type of pollution at present. Researchers at India's Bhabha Atomic Research Centre reached this conclusion in mouse experiments and stated that it can be applied to humans.
7. Coffee's health care and medical functions. Coffee has effects such as resisting oxidation and protecting the heart, strengthening muscles and bones, benefiting the waist and knees, stimulating appetite and promoting eating, reducing fat and resolving food accumulation, opening the orifices and removing dampness, invigorating blood and resolving stasis, and calming wind and stopping spasms.
8. Coffee's influence on mood. Experiments show that the average person's absorption of 300 milligrams of caffeine per day (about 3 cups of brewed coffee) will have a good effect on a person's alertness and mood.
The benefits and drawbacks of drinking coffee: the following six types of people experience more drawbacks from drinking coffee
People with hypertension, coronary heart disease, arteriosclerosis, and other diseases — long-term or heavy coffee consumption may induce cardiovascular disease.
Elderly women — coffee consumes calcium and causes osteoporosis. After menopause, women need to increase their daily calcium supplementation tenfold.
People with stomach diseases — excessive coffee consumption may worsen stomach conditions.
Pregnant women — excessive coffee consumption may cause fetal malformation or miscarriage.
People deficient in vitamin B1 — vitamin B1 is responsible for maintaining the balance and stability of the nervous system, and coffee can damage it.
Cancer patients — excessive coffee consumption also carries carcinogenic risks for ordinary people.
Doctors remind people not to drink coffee on an empty stomach, because coffee stimulates gastric acid secretion, and people with gastric ulcers should be especially cautious. As a beverage, coffee should be consumed in moderation according to one's own condition, and overall nutrition science still emphasizes a balanced diet and eating fewer spicy and stimulating foods.
Drinking coffee has many benefits and drawbacks, and the negative effects of moderate consumption are not great. In addition, it should be noted that people with hypertension should avoid drinking caffeinated beverages when under great work pressure. This is because caffeine itself may raise blood pressure, and when combined with emotional tension, it can produce a dangerous synergistic effect.
