I suddenly want to drink coffee recently. What are the benefits of drinking coffee?

Nicotinic acid in coffee contains vitamin B, and roasted coffee beans contain more vitamin B than raw coffee beans. Others also contain free fatty acids, caffeine, tannic acid and so on. Although coffee contains calories, its content is very small, and the calories will increase only after adding sugar and creamer. When you are tired, your body will naturally eat sugary food, but you want to eat chocolate or egg-like coffee. This is because your body needs heat. In this way, coffee and milk are both very nutritious drinks.

Coffee is good for the skin.

People used to say that drinking coffee would make the skin black, but in fact, melanin in the skin has nothing to do with melanin in coffee. Therefore, this is groundless, but most women are shaken by this statement. On the contrary, coffee can promote metabolism and activate digestive organs, so it has a great effect on constipation. Once constipation is cured, the roughness of the skin will be changed. In addition, about 40 years ago, female singer Yabe Rehn tried coffee bath for the first time. It is said that it has a good and firm effect on eliminating body fat, but it is not recorded in detail. Like sand bath, bathing with coffee powder is a kind of hyperthermia, which makes the whole body hot and sweaty and achieves the effect of losing weight.

③ Coffee has hangover relieving function.

Indeed, coffee can activate the liver or kidneys. If you drink coffee after drinking, acetaldehyde converted by alcohol will be rapidly oxidized and decomposed into water and carbon dioxide to be excreted. Black tea and green tea have the same effect. Please be sure to finish a cup of coffee!

Coffee can eliminate fatigue.

To eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic function. Coffee has a third function, which can promote the function of the heart, make the blood circulation smooth, supply oxygen and nutrients to the whole body quickly, help the liver to deal with the waste in the body and excrete it through the kidneys. This function of promoting metabolism can effectively eliminate fatigue. When you can't get enough rest or sleep because of work, you can also use sweet chocolate and coffee to help refresh yourself.

Caffeine has strong stimulation and fragrant smell, which can easily stimulate the central nervous system through the brain-blood barrier, promote brain activity, make the mind more sober, lively and sensitive, fully concentrate thinking ability and attention, and improve work efficiency; Can stimulate the brain and skin, and promote feeling, judgment, memory and emotional movement. When you are dizzy, the easiest way is to make yourself a cup of strong tea or coffee. These drinks are refreshing and have been effective since ancient times. At the same time, from getting up, washing cups, to pouring water from the water dispenser, the whole exercise process will bring you a moment of sobriety. When you are awake, get into work quickly, but be careful not to put the teacup in the wrong place, or you will really wake up when you are distracted and spill water all over the floor.

⑤ Three cups of coffee a day can prevent gallstones.

Delicious coffee is a refreshing drink, and the latest research also found that drinking several cups of coffee every day can prevent gallstones. According to the latest issue of the Journal of the American Medical Association, researchers at Harvard University found that men who drink two or three cups of coffee a day have a 40% lower risk of gallstones than men who don't drink coffee. If they drink more than four cups of coffee a day, the risk of gallstones will drop to 45%.

However, decaffeinated coffee has no such effect. Only caffeinated coffee can stimulate gallbladder contraction and reduce cholesterol which is easy to form gallstones in bile. However, other beverages such as tea and cola, which also contain caffeine, cannot achieve the same effect because the caffeine content is lower than that of coffee.

Drinking coffee often can prevent radiation damage.

Radiation damage has become a prominent pollution and harm at present. Especially the radiation of household appliances: for example, people who operate computers for a long time, microwave ovens and televisions at home. Especially for pregnant women, radiation has affected the health of the next generation. Reports in this regard are not uncommon.

Indian scientists have found that coffee can protect laboratory mice from radiation damage and may have the same effect on humans. Researchers at the Baba Atomic Research Center in India found that 70% of the injected mice were still alive 25 days after receiving high-dose radiation, while all the mice without injection died. Kaye Billy George, who led the study, said that this discovery may also apply to humans. He said: "studies do show that coffee may help prevent radiation damage."

⑦ The health function of coffee.

Antioxidant and heart protection-Coffee not only refreshes, but also contains polyphenols, which not only has antioxidant effect, but also has cardiovascular protection function. Recently, the food chemistry seminar of the annual meeting of the American Chemical Society has new scientific evidence: coffee contains powerful antioxidants and has the function of protecting the heart and blood vessels.

This study was conducted by Professor Vincent of Scranton University in Pennsylvania, USA. Vincent found that coffee contains a high content of phenolic compounds, which are sometimes called flavonoids. These compounds are powerful antioxidants, which can resist oxidation and anticoagulation.

Strengthening bones and muscles, benefiting waist and knees-Caffeine can make muscles contract freely, increase muscle mass, reduce exercise valves, increase body sensitivity and improve exercise function.

Appetizing and promoting food-Caffeine can stimulate sympathetic nerve, stimulate gastrointestinal secretion of gastric acid, promote digestion, prevent abdominal distension and gastroptosis, and promote gastrointestinal hormones, peristalsis hormones and peristalsis hormones, thus quickly relieving constipation.

Reducing fat and promoting digestion-Caffeine can accelerate the decomposition of fat, improve the body's metabolic rate, increase heat consumption, and help to reduce fat and weight.

Tongqiao Qushi-Caffeine can promote renal function, expel excess sodium ions from the body, increase urination, improve abdominal distension and edema, and help to lose weight.

Promoting blood circulation and removing blood stasis-Linoleic acid contained in coffee can hemolyze and prevent thrombosis, enhance vasoconstriction, promote blood circulation and relieve headaches caused by vasodilation, especially migraine. In addition, it can promote venous return, moisturize skin, restore muscle surface elasticity and prevent cardiovascular diseases.

Stop wind and spasm-coffee can increase high-density cholesterol, accelerate the metabolism of bad cholesterol, reduce coronary atherosclerosis and reduce the chance of stroke.

The influence of coffee on people's mood.

Recently, Professor Smith of the University of Bristol in the United Kingdom published his 10 report, studying the effects of coffee on the brain, especially on discrimination and emotion. Their discrimination and alertness were measured 30 minutes before and after drinking coffee. Smith found that after drinking a cup of coffee, they became more alert and more focused. Professor Smith said that coffee can really refresh you, especially when you don't have enough sleep, and if you have to concentrate on work or exams during the day, drinking a cup of coffee will definitely promote your alertness and help you tide over the difficulties, and coffee will stay in your body for three to five hours, so coffee has a long-term refreshing effect.

Further experiments also found that the average person can absorb 3000 mg (about 3 cups of brewed coffee) of caffeine every day, which will have a positive impact on a person's alertness and mood. But when caffeine exceeds 400 mg (four cups), it will bring side effects, such as bad mood, irritability, aggression and trouble. If you just want to eat polyphenols in coffee for antioxidant effect, then you only need to drink coffee with caffeine!
