Coffee and health
When it comes to coffee, people will associate it with caffeine, a softer stimulant in coffee, which can increase the body's sensitivity, concentration, accelerate the body's metabolism, and improve the body's mental state and physical performance. Currently, humans have discovered caffeine in about 60 planted species, the most well-known of which are tea and coffee.
What kind of person is not suitable for drinking coffee
Coffee contains caffeine, and whether or not there is any reaction to caffeine varies from person to person. For example, some people are allergic to pollen, while others are not suited to seafood. And both of these conditions will have no effect on the vast majority of people like you and me. As for the appropriate amount of coffee to drink per day, in some large coffee consuming countries, the average daily intake of caffeine is about 250-600 milligrams. Repeated scientific studies and analyses have shown that this dose has no side effects on the human body. Therefore, you can drink 4-10 cups of instant coffee every day.
How does coffee affect your health
Your main concern is whether the caffeine in coffee has any effect on your health. In fact, caffeine is one of the softer stimulants in coffee, which can increase the body's sensitivity and concentration, accelerate the body's metabolism, and improve the body's mental state and physical performance. At present, human beings have found caffeine in about 60 kinds of plants, of which the most well-known are tea and coffee. In some coffee-consuming countries, the average daily intake of caffeine is about 250-600 milligrams. This dose has been repeatedly studied and analyzed scientifically and has no side effects on the human body.
How much coffee is too much
People often ask how much coffee is too much. In some large coffee consuming countries, the average daily intake of caffeine is about 250 to 600 milligrams, which has been repeatedly studied and analyzed by scientific research, and this dosage does not have any side effects on the human body. This is because the caffeine content of a cup of coffee (150 ml) is generally:
- Ground coffee: about 80-90 ml
- Instant coffee: about 60 ml
The caffeine content of a cup of coffee (150 ml) is generally:
In some of the major coffee consuming countries, people consume an average of about 250-600 milligrams of caffeine per day. This dose has been repeatedly studied and analyzed scientifically and has no side effects on the human body. A cup of instant coffee (about 150 milliliters) typically contains about 60 milligrams of caffeine, so drinking 4-10 cups of instant coffee a day is not excessive.Effects of coffee
Alcohol or tobacco can be intoxicating and stimulating, as can caffeine. Caffeine has the effect of stimulating the central nervous system or muscles, which can restore muscle or fatigue, increase work efficiency, have a sobering effect and make the mind more responsive.

It also stimulates the sympathetic nerves, which can suppress the shortness of breath caused by the excitement of the parasympathetic nerves. Other coffee also has the effect of helping digestion, especially when eating too much meat, gastric juice secretion, to promote digestion, to prevent gastroptosis. Since caffeine can break down fats, after eating calorie-rich food, Westerners will want to drink coffee. Since caffeine does not eliminate the garlic effect and contains betel nut, coffee is an indispensable drink after eating flavorful dishes.
In addition, coffee has a deodorizing effect. You can use the residue of ground coffee in a container to dry it and put it in the refrigerator or shoe box as a deodorizer. Sprinkle it in an ashtray to get rid of tobacco odor. Coffee can also be used to hide flavors. For example, instant coffee dissolved in boiling water, so that the flavor of the meat can be stained on the meat can become a sweet and savory meat dishes.

The influence of coffee on people's emotions
Recently, Prof. A.P. Smith of the University of Bristol published a ten-year study on the influence of coffee on the brain and nerves, and in particular on the influence of coffee on the emotions of the cognitive ability. He measured the cognitive ability and alertness of people thirty minutes before and after they drank a cup of coffee. Smith found that those who drank a cup of coffee, they became more alert, but also more able to concentrate, Professor Smith said, coffee can indeed refresh, especially when you do not have enough sleep, if the cold makes you sleep well, or insomnia, and you must focus on the daytime to work or to cope with the examination, then a cup of coffee will certainly promote your alertness, so that you get through the difficult times, and the coffee will be in the body to stay for 2 to 5 hours, so coffee has the ability to help the brain to recognize the mood. Coffee will stay in the body for 2 to 5 hours, so coffee has a long time refreshing effect. Further experiments also found that: the average person can absorb 300 milligrams (about three cups of brewed coffee) of caffeine per day, and a person's alertness and mood will have the following influence. However, over 400 milligrams (four cups) of caffeine will bring about side effects, such as bad mood, irritability, aggression, and trouble. If you only want to consume the polyphenols in coffee for their antioxidant effects, then just go for the "fdecaf" coffee!
Study finds coffee drinkers less likely to get Parkinson's disease. Scientists at the Veterans Administration Medical Center in Honolulu, Hawaii, have found in a survey that non-coffee drinkers have a five times higher risk of Parkinson's disease than those who drink more than five cups of coffee a day. The researchers*** followed more than 8,000 men for 30 years, and their findings have been published in the Journal of the American Medical Association. Parkinson's disease is an age-related condition in which lesions occur in the nervous system6 and typical symptoms include tremors, stiffness and reduced voluntary movement in the limbs. The reason why drinking coffee may reduce the risk of Parkinson's disease is currently unknown to the researchers. However, they hypothesize that the caffeine contained in coffee could potentially play a role in preventing damage to the nerve cells that cause Parkinson's disease. The scientists noted that their results so far are preliminary and need to be confirmed by further studies. They emphasized that it is too early to recommend coffee drinking as a treatment for Parkinson's disease.
Coffee and the prevention of gallstones
Aromatic coffee is a refreshing drink, and the latest research has also found that every few cups of coffee can prevent gallstones. The latest issue of the Journal of the American Medical Association reported that researchers at Harvard University found that men who drank two or three cups of coffee per day were 40 percent less likely to get gallstones than those who didn't drink coffee, and the chance of getting gallstones dropped to 45 percent if they drank more than four cups of coffee a day. However, decaffeinated coffee does not have this effect. Only caffeinated coffee can stimulate the gallbladder to contract and reduce the cholesterol in the bile that is prone to forming gallstones. Other beverages such as tea and cola, which also contain caffeine, cannot achieve the same effect because their caffeine content is lower than that of coffee.
Coffee's antioxidant and cardiovascular protection
In addition to refreshing the mind, coffee contains polyphenols, which not only have antioxidant effects, but also protect cardiovascular function. The recent symposium on food chemistry at the annual meeting of the American Chemical Society has proved that coffee contains powerful antioxidant substances, which have the function of protecting the heart and blood vessels. The study was conducted by the University of Scranton, Pennsylvania, USA, and these polyphenolic compounds, sometimes called flavonoids, are powerful antioxidants that fight oxidation and blood clotting.
Coffee and the prevention of radiation damage
Radiation damage has become one of the more prominent types of contamination and hazards today. Especially the radiation of household appliances: such as long-term operation of the telephone people, home microwave ovens, televisions and so on. Especially on the radiation of pregnant women, has affected the health of the next generation. Reports in this regard are common. Indian scientists found that coffee can protect experimental rats from radiation damage, and may also have the same effect on humans. India Ba Ba Atomic Research Center researchers, injected with caffeine in the experimental rats in general enough to die after receiving high doses of radiation, 70% of the twenty-five days after the still alive, while did not receive the injection of the rats were all dead. Kaye Pilicho, who led the study, said the findings may also apply to humans, saying, "The study does show that coffee may help prevent injury."
Does coffee cause calcium loss?
In recent years, as people have become more and more concerned about calcium loss and osteoporosis, there has been considerable skepticism about coffee, and the relationship between caffeine intake and osteoporosis is still being studied. There is no direct evidence that caffeine causes osteoporosis, but some studies have pointed out that caffeine increases the excretion of calcium. Therefore, it is recommended that coffee lovers should eat more high-calcium food to supplement calcium, such as preparing cheesecake or cheesecake with coffee, not only to supplement calcium, but also to make the coffee more delicious.
These people are not suitable for coffee?
Coffee is not suitable for people with cerebral hemangiomas, and heart patients should drink decaffeinated or non-caffeinated coffee, as caffeine can increase the heart rate and cause a lack of oxygen to the heart. In addition, skin disease patients and those with stomach problems should try to drink less coffee, so as not to cause excessive and lead to the deterioration of the condition. Diabetics should also avoid drinking coffee with too much sugar to avoid aggravating their condition. The U.S. Food and Drug Administration (FDA) has issued a statement advising women who are pregnant or may become pregnant to reduce their caffeine intake. This is because pregnant women metabolize caffeine twice as fast in the second and third trimesters of pregnancy as they do when they are not pregnant, and caffeine also crosses the placenta into the fetus, and also passes into the baby through breastfeeding. Besides, many studies have not proved that caffeine in moderate amounts can cause adverse effects on the fetus, and there are no medical reports that prohibit pregnant women from drinking coffee. However, pregnant women and breastfeeding women are advised to be more cautious about caffeine intake. In short, if you find yourself feeling unwell after drinking coffee, you should refrain from drinking it for a while, and then start with a small amount and change the way you drink it.

Coffee may make you sleepless at night or raise your blood pressure. But Professor Martin, director of the Coffee Research Institute at Vanderbilt University in the United States, said recently that coffee contains hundreds of healthful ingredients that can fight liver damage, various cancers, asthma, heart disease and tremor paralysis.
He noted that drinking 2-4 cups of coffee a day is beneficial. People who don't drink coffee are more likely to suffer from these diseases than coffee drinkers. Nearly 20 years of research has confirmed that caffeine, the active ingredient in coffee, activates the central nervous system and can be used to make long-acting analgesic drugs that can fight drowsiness, colds and flu, asthma and edema. Its side effects are addictive insomnia, nervousness and elevated blood pressure.
Research has shown that coffee contains an anti-dementia substance, which reduces the effects of harmful substances on the body and helps protect against some diseases. Scientists say that when oxygen is mixed with other chemicals in the body, harmful substances that blindly destroy cells and body tissues are formed, which is the causative cause of heart disease, vascular disease, tumors, weakening of the immune mechanism and neurasthenia. The results of a study by the American Coffee Research Institute show that coffee contains anti-dementia substances four times higher than tea. Nutrition plays a major role in strengthening the body's disease prevention mechanisms, and anti-dementia substances include vitamin E, vitamin C, carotenoids in soybeans, red wine, certain spices, fruits, onions and olives. The anti-dementia properties of roasted coffee beans are even stronger, and this substance is not diminished or destroyed in decaffeinated coffee.
At the same time, experts pointed out that a cup of coffee after getting up in the morning can wake up the brain, and a sip of coffee during the daytime work can be refreshing.

Elderly women - coffee will reduce calcium, cause osteoporosis. After menopause, women need to add ten times the amount of calcium per day.
Gastric patients - drinking too much coffee can cause worsening of stomach problems.
Pregnant women - drinking too much coffee can lead to fetal malformation or miscarriage.
Vitamin B1 deficient people - Vitamin B1 can maintain the balance and stability of the nervous system, and coffee has a destructive effect on it.
Cancer patients - Drinking excessive amounts of coffee poses a cancer risk to normal people.
Close contact with coffee
Caffeine can invigorate the spirit, enhance thinking ability, and restore muscle fatigue due to its effect of stimulating the central nervous system and muscles. Acting on the cardiovascular system, it can improve heart function, stretch blood vessels and promote blood circulation. For the gastrointestinal system, it can help digestion and the decomposition of fat.
Helps weight loss
I believe many people have heard that drinking black coffee can help you lose weight, in fact, this is only one of the factors, caffeine can indeed accelerate the breakdown of fat, but at the same time, it is more important to rely on the movement of the muscles, in order to convert the excess fatty acids into calories to be consumed, and if there is no movement to go along with it, excess fatty acids flow back down the bloodstream to build up the fat again. Fat will build up again. Therefore, after drinking coffee, you need to be active at the same time, in order to play a real weight loss effect! Coffee itself has calories, but not many. The main calories are in the creamer and sugar you add to your coffee.
Antioxidant capacity
In recent years, as long as the antioxidant function of the food are in the market in a big way, generally known vegetables and fruits rich in A, C, B vitamins, as well as quite popular in Japan, the tea, the reason why it is regarded as a healthy food is that they are rich in antioxidants, can fight the free radicals on the human body's damage. A few days ago, a research report pointed out that coffee contains four times more antioxidants than tea, and can fight cardiovascular disease, and coffee itself is also in line with the principle of antioxidants, color (dark) and has a bitter taste. The antioxidant content of each coffee varies according to the way it is brewed, for example, Americano contains the least amount of antioxidants, while Espresso contains the most antioxidants. Coffee does not lose its antioxidant effect when creamer is added.
Improve dry eyes
Overseas reports indicate that coffee drinkers are significantly less likely to suffer from dry eyes than non-coffee drinkers. This is mainly related to the purine component of coffee (eye drops containing purine, can stimulate the glands to secrete fluid, the eyes have some kind of protective effect). This is certainly good news for coffee drinkers, but it should be noted that coffee itself has a diuretic effect, and even though some of its components have a protective effect, caffeinated beverages must be banned from those who already suffer from dry eye, as well as from those who take any medication containing diuretic ingredients, so as not to exacerbate the loss of water from the body.
Can relieve pain
Headaches caused by a night's sleep, or pain caused by vasoconstriction on the side of the temples, which are not caused by organic factors, can be relieved by coffee, but it must be drunk in the morning or at noon (note: prohibited from late afternoon to night).
The amount of coffee
Coffee is good for the human body but you can't drink too much of it, no more than 2 cups a day, for people who are easily nervous and anxious, drinking too much of it may be harmful.
Drinking coffee time
Drinking coffee is best after breakfast and lunch, because it can promote gastrointestinal peristalsis, help digestion, and break down the high-calorie, high-fat food that is eaten, and will not stimulate the intestines and stomach, like drinking coffee on an empty stomach. It is best not to drink coffee after dinner for fear that it will have an impact on sleep.
If you want to stay up all night by drinking coffee, you may drink too much without realizing it, which is not good for your body.
Caffeine helps improve alertness, sensitivity, memory and concentration. But drinking more coffee than you're used to can be similar to consuming the same dose of a stimulant, which can cause nervousness. For people who tend to have anxiety disorders, caffeine can cause sweaty palms, palpitations, and ringing in the ears to worsen these symptoms.
Exacerbating high blood pressure
Caffeine is often compounded with other simple painkillers because of its own painkilling properties, but taken in large amounts over a long period of time, using large amounts of caffeine will only worsen your condition if you already have high blood pressure. Because caffeine alone can raise blood pressure, and when combined with emotional stress, it can have a dangerous multiplying effect, people at risk for high blood pressure should especially avoid caffeinated beverages during stressful times at work. Some people who are regular coffee drinkers think they are immune to the effects of caffeine, but this is not the case, as one study showed that a cup of coffee can raise blood pressure for up to 12 hours.
Inducing osteoporosis
Caffeine itself has a good diuretic effect, and if you drink a lot of coffee for a long time and a lot of it, it is easy to cause bone loss, which will have a negative impact on the preservation of bone mass, and in the case of women, it may increase the threat of osteoporosis. However, the premise is that the usual food originally lack of intake of sufficient calcium, or infrequent movement of people, coupled with post-menopausal women, due to the lack of estrogen caused by the loss of calcium, the above conditions plus a large amount of caffeine, may pose a threat to the bone. If you can enjoy it in reasonable amounts, you can still do it without choking.
Drink coffee with caution for these people
People with liver disease
Caffeine prolongs the time it takes for caffeine to thank in the body. Normal adult caffeine metabolism takes 2 hours, but patients with liver disease or liver dysfunction, the metabolism of caffeine may take 4-5 hours, so patients with liver disease should be careful when drinking coffee, it is best not to drink in the evening, so as to avoid the metabolism of the long time affecting the sleep, and it is best to not more than 1 cup a day.
Patients with digestive disorders
Believe that often in the stomach pain stomach disease people have an experience, is the doctor will certainly instruct, stimulating food do not eat, including: wine, chili, coffee, tea, carbonated beverages.
The reason why coffee is on the list is that the tannins in it stimulate the secretion of gastric acid, which must be avoided if the patient is in the acute stage of digestive diseases. After the recovery of health, if you occasionally drink coffee, it is also best to use after meals, avoid drinking coffee on an empty stomach.
Pregnant women
Many women start from the beginning of their pregnancy and pay special attention to all the food they eat, and drinks containing caffeine are of course listed as one of the taboos. This is mainly due to the slow metabolism of caffeine for pregnant women, caffeine stays in the body for a longer period of time, the fetus in the womb until eight or nine months, to be able to metabolism, remove the caffeine in the blood.
Children
Because of the incomplete development of children's liver and kidneys, the detoxification ability is poor, so that the half-life of caffeine metabolism will be extended, so in general, children under the age of 12 years old need to prohibit the intake of caffeine. Even if you drink coffee as water all day long in Europe and the United States, there are very strict restrictions on children drinking coffee.
