Drinking a moderate amount of coffee, that is, only two to four cups a day, will do no harm to your health. Some studies have found that drinking too much coffee can lead to bone loss. People with high blood pressure had a significant increase in blood pressure after drinking two or three cups of coffee a day. People who drink a lot of caffeinated drinks every day are mostly people who work too much, work too hard and are in poor health. People who drink a lot of coffee also tend to have the habit of smoking, and smoking has been proved to be associated with many serious diseases, not because of drinking coffee.

The main ingredients of coffee

Caffeine: it has a particularly strong bitter taste and stimulates the central nervous system, heart and respiratory system. Appropriate amount of caffeine can also reduce muscle fatigue and promote digestive juice secretion. Because it promotes kidney function, it is diuretic and helps the body to expel excess sodium ions from the body. But eating too much can lead to caffeine poisoning.

Tannic acid: the boiled tannic acid will decompose into pyrouric acid, so the coffee that has been brewed for too long will taste worse.

Fat: the most important ones are acid fat and volatile fat.

Acidic fat: that is, fat contains acid, its strength will vary according to the type of coffee.

Volatile fat: is the main source of coffee aroma, it is a kind of aroma will emit about 40 kinds of aromatic substances.

Protein: the main source of calories, the proportion is not high. Most of the protein in coffee powder will not dissolve out when brewing coffee, so the intake is limited.

Sugar: coffee beans contain about 8% sugar. After baking, most of the sugars are converted to caramel, which browns the coffee and combines with tannins to produce sweetness.

Fiber: the fiber of raw beans will be carbonized after baking and combine with caramel to form the hue of coffee.

Minerals: contains a small amount of lime, iron, phosphorus, sodium carbonate and so on.

Caffeine and low caffeine

The most remarkable thing about caffeine is that the taste of coffee has nothing to do with how much caffeine it contains. Caffeine itself has a slight bitter taste, and its concentration basically comes from the degree of roasting (the deeper it is, the thicker it is). The concentration of coffee is formed by the ratio of coffee to water in the process of brewing.

An ordinary 142g cup of coffee contains 60-180mg (mg) of caffeine, depending on the concentration of coffee and the type of coffee used when mixing.

An ordinary 42g (g) Espresso contains 90-120mg (mg) of caffeine. The amount of caffeine also depends on the concentration of coffee and the type of coffee used when mixing.

The roasting process has little effect on caffeine. Caffeine above 77 degrees Celsius can be quickly dissolved in water, so it has been completely dissolved with coffee during brewing.

Different kinds of coffee trees also contain different amounts of caffeine. Arabica coffee contains about 1% per cent caffeine, while robusta coffee contains about 2% per cent caffeine.

Whether caffeine has an effect on health is a topic of great concern to many people. So far, there is no conclusive evidence that drinking coffee is harmful to human health.

Many studies have shown that coffee is actually good for the human body in many ways. For example, coffee can stimulate athletes to create better results, and the moderate stimulation caused by coffee is beneficial to many daily activities, such as relieving work stress, refreshing effect, and so on. Drinking a moderate amount of coffee will not affect human health, but it is a good drink.

Low caffeine

All ways to remove caffeine are to increase the moisture content of green coffee beans (unroasted coffee beans), making it easy to remove caffeine. The caffeine is then extracted with a solvent, dried in the sun, and shipped to the roaster.

The solvents used to remove caffeine include water, ethyl acetate, chloromethane and carbon dioxide. These methods can be used to produce safe, good-tasting decaf coffee. The flavor of decaffeinated coffee depends on the quality of the beans, the properties of the blend, the roasting techniques and the methods used to remove caffeine.

The benefits of coffee

Coffee contains certain nutrients. Nicotinic acid in coffee contains vitamin B, which is higher in roasted coffee beans. And there are free fatty acids, caffeine, tannic acid and so on.

Coffee is good for the skin. Coffee can promote metabolic function, activate digestive organs, and has a great effect on constipation. Taking a bath with coffee powder is a kind of thermotherapy, which has the effect of losing weight.

Coffee has the function of relieving alcohol. Drinking coffee after drinking alcohol will quickly oxidize the acetaldehyde converted from alcohol, decompose it into water and carbon dioxide and discharge it out of the body.

Coffee can relieve fatigue. In order to eliminate fatigue, we must supplement nutrition, rest and sleep, and promote metabolic functions, and coffee has these functions.

Three cups of coffee a day can prevent gallstones. For caffeinated coffee, it stimulates gallbladder contraction and reduces cholesterol, which is prone to gallstones. The latest Harvard University researchers found that men who drank two to three cups of coffee a day were less than 40% likely to get gallstones.

Drinking coffee regularly can prevent radiation damage. Radiation damage, especially the radiation of electrical appliances, has become a prominent pollution at present. Indian Barba atomic researchers have come to this conclusion in mouse experiments and say it can be applied to humans.

The health care and medical function of coffee. Coffee has the functions of anti-oxidation and heart protection, strengthening muscles and bones, benefiting waist and knees, appetizer, eliminating fat and accumulation, promoting orifice and dehumidification, promoting blood circulation and removing blood stasis, relieving wind and relieving spasm and so on.

The influence of coffee on mood. Experiments show that the average person absorbs 300 milligrams of caffeine (about 3 cups of brewed coffee) a day, which has a good effect on a person's alertness and mood.

The disadvantages of coffee

Make a mess when you are nervous

Caffeine helps to improve alertness, agility, memory and concentration. But drinking more coffee than you are used to will produce the same dose of stimulants that you are used to, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus.

Aggravate hypertension

Caffeine is often combined with other simple painkillers because of its analgesic effect, but if you take it in large quantities for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, coupled with emotional stress, it can have a dangerous multiplication effect, so people at risk of high blood pressure should especially avoid drinking caffeinated drinks during stressful times at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. One study shows that blood pressure can rise for up to 12 hours after drinking a cup of coffee.

Induce osteoporosis

Caffeine itself has a good diuretic effect, if you drink a lot of coffee for a long time, it is easy to cause bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis for women. But the premise is that people who don't get enough calcium in normal food, or people who don't move very often, plus women after menopause, calcium loss caused by lack of estrogen, coupled with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still stop eating for fear of choking.
