Coffee is one of the world's three major beverages, especially in Europe and the United States, and is a long-established daily drink. Because coffee can promote the body's fat metabolism, many fitness iron enthusiasts began to pay more attention to it. The main active ingredient of coffee is caffeine. Of course, in addition to caffeine, coffee also contains a variety of ingredients such as tannic acid, alkaloids and the like. The raw coffee beans for making coffee also contain nutrients such as sugar, protein, fat, niacin, potassium, crude fiber, water and so on. We saw a cup of coffee in front of us, actually a bowl of complex soup made from a variety of substances. (I haven’t counted the sugar, creamer, cinnamon powder for seasoning) Caffeine, caffeic acid and chlorogenic acid in coffee can fight free radicals and have antioxidant properties. Coffee also contains a lot of polyphenolic compounds, which have a certain role in preventing thrombosis. Recently, according to a study by Americans, people who drink 2-3 cups of coffee a day have an average 40% less chance of gallstones than those who never drink coffee. Of course, this cannot be ruled out as a paradox attack by the capitalist camp to dump coffee to these tea-based countries! In any case, the study of caffeine, the main active ingredient in coffee, has been relatively mature and has been conclusive. Caffeine is a plant alkaloid found in many plants. For plants, it is a natural evolutionary natural insecticide that can paralyze insects that contain caffeine plants, so as to protect themselves from being eaten as little as possible by insects. From a biochemical point of view, caffeine is a xanthine alkaloid compound that is a stimulant for the human body. Caffeine is completely absorbed by the stomach and small intestine within 45 minutes after being drunk with coffee. After absorption, it will be “pervasively†distributed to all organs of the body, including into the spinal cord! In the liver, a series of very complex reactions are broken down into three primary metabolites called paraxanthine (84%), theobromine (12%), and theophylline (4%). These three dimethyl jaundices have different effects on the body: Paraxanthine (1,7-dimethylxanthine, 84%) can accelerate the decomposition of fat, and the main effect of drinking coffee to lose weight is from this substance. Studies have shown that 100 mg of caffeine (about 1 cup of coffee) can accelerate the decomposition of fat, increase the body's metabolic rate by 3-4%, and increase the consumption of heat. Theobromine (12%) can dilate blood vessels, increase urine output, and have a diuretic effect, so the number of times of going to the toilet after drinking coffee will increase. Theophylline (4%) can soothe the smooth muscles of the bronchi and can be used to treat asthma. Of course, the amount of treatment is very large, definitely not the method of drinking coffee, so although it has such a role, it is impossible to rely on coffee to relieve asthma. Finally, these compounds are further metabolized in the human body. After about 3-4 hours, the caffeine that a healthy adult drinks can reach half-life (people who are interested in physics, especially radioactive elements, will be familiar with the term, coffee The time it takes for the body to convert half of the caffeine ingested by the so-called half-life). Pregnant women and children will have a lot of time this time, so pregnant women and children still do not drink coffee. There are also some people with liver problems who accumulate caffeine due to metabolic disorders. The half-life may be extended to 96 hours. It is also important to consider whether to use coffee as a drink. Eventually all of the metabolites are excreted through the kidneys through the urine to complete a cup of coffee travel in the human body. Caffeine is both a central nervous system stimulant and a metabolic stimulator. Caffeine can increase the activity of nerve cells, and the secretion of adrenaline accelerates the heartbeat, increases blood pressure, and increases the neurotransmitter dopamine in the brain to produce refreshing and relieving fatigue. Of course, caffeine does not reduce the amount of sleep time the body needs. It can only temporarily weaken the feeling of sleepiness, so it can be used for refreshing moments. It is useless to stay up late for a long time. Caffeine is a function enhancer: the ability to boost the brain and body. It can excite the central nervous system, increase people's alertness, and make thinking fast and clear (this is probably the reason why many famous philosophers in Europe in the early days were soaked in cafes), increasing their attention and maintaining a good physical condition. . For fitness and exercise, caffeine increases blood flow in the muscles and reduces blood flow to the skin and internal organs (these blood goes to the muscles to replenish the movement), and the liver releases glucose into the bloodstream (providing exercise) Energy), as well as the role of excitement in the brain and respiratory center. Together, these promote the body's motor function. As early as the 1970s, studies showed that athletes who took caffeine increased their performance by 7% in long-distance bicycle programs. For trained runners, after taking caffeine, the straight-line running durability increased by 44%, and the ring running endurance increased by 55%. This is really an exciting news! Coffee can also promote the metabolism of fat (that is, what is said to burn fat in the propaganda, of course, scientifically speaking, the metabolism of fat that is slowly carried out in the human body is also called burning, but the old feeling that burning is misleading the masses It makes people feel that fat will "burn" down a large piece of the body, and it can improve the body's athletic ability and relieve fatigue. It is really a good medicine for exercise and fitness! But how much coffee everyone needs to drink can produce different results, depending on body type and caffeine tolerance. I would like to believe that the Harvard School of Public Health studies about 2 cups a day. When is it better to drink? The caffeine we drink can start to work in the body in less than an hour, and the effect disappears within 3 to 4 hours, and the action time is quite short. So you can drink a cup of coffee one hour before exercise, which not only supplements some of the water needed for exercise, but also improves your athletic ability and consumes more fat during exercise. After 3-4 hours after the exercise, if you are still tired, take another drink and use the effect of caffeine to help us relieve fatigue as soon as possible. Or after lunch (drinking after dinner, it will affect your sleep). Drinking a cup of coffee for about 1 hour can help digestion and promote fat burning. Because caffeine can stimulate gastrointestinal hormones or motility hormones, there is also a laxative effect. As for which coffee to choose, it depends on personal hobbies and economic strength. But one thing to note is that you don't need to add sugar and try to add less creamer. The black coffee (100 grams) without any cup is only 2.55 kilocalories. After adding sugar and milk, it is hard to say how much it will increase. . Anyway, 1 gram of sugar has 4 kilocalories of heat, and a spoonful of sugar is about 3-4 grams. I know how much calories I have with coffee. Different coffees contain different amounts of caffeine. Freshly brewed or freshly ground coffee is about 130-680 mg/L, decaffeinated coffee is only 13 to 20 mg/L, instant coffee is about 130-400 mg/L, and Italian espresso is as high as 3400 mg/L, so every Cup coffee has an average of 40-100 mg of caffeine. In fact, many foods and beverages have caffeine. If you don't like the taste of coffee, you can get caffeine from other foods to achieve the goal of fitness and weight loss. Tea is another important source of caffeine. The caffeine content of each cup of tea is generally only half that of coffee, and the content of tea of ​​different varieties is very different. Chocolate is made from cocoa powder, so it also contains a small amount of caffeine, but its heat is too high. It is a bit ridiculous to want to use caffeine to reduce fat and eat chocolate. There are also soft drinks like cola, which usually contain between 10 mg and 50 mg of caffeine per bottle. The disadvantage is that the overall calories are too high. Coffee has so many benefits, but still can't drink in unlimited quantities. Because drinking coffee for a long time (more than 5 cups a day) can lead to the body's habituation of caffeine. Suddenly interrupted coffee, the body will be too sensitive to adenosine, blood pressure will be excessively reduced, leading to headaches and other symptoms. At the same time, a drastic overdose of coffee (more than 250 mg, equivalent to 2-3 cups of brewed coffee) can cause excessive nervousness in the central nervous system. Causes irritability, nervousness, excitement, insomnia, blushing, increased urine, gastrointestinal disorders, muscle twitching, distracted thinking, irregular or too fast heartbeat, and agitation. At the same time, caffeine will increase the acidity of the stomach, and whether it is normal coffee or decaffeinated coffee, it will stimulate the gastric mucosa and increase gastric acid secretion, so patients with gastritis and gastric ulcer should not try it easily. At the same time, the medical community believes that caffeine is related to bone loss and osteoporosis, so it is recommended to drink caffeine-containing beverages such as coffee and tea in moderation. It is mentioned several times before, about 2 cups a day, drink in moderation, you can enjoy the tongue fast, and at the same time achieve the purpose of promoting health.
