Hello! I work as a doctor for 21 years. My name is George O. Sapego. This article will talk about the benefits and dangers of caffeine.
Coffee and tea - is the most popular stimulant. Approximately 90% of people around the world every day consume caffeine. In richer countries, people often drink coffee, not tea.
In these hot drinks in addition to caffeine is still a lot of different components that can be useful or harmful to health.
Still we have not decided to declare tea and coffee definitely harmful or definitely useful.
It is considered that 400 mg of caffeine per day, on average, are safe. This is where some 3 cups of coffee or tea a little bit more.
Coffee and black tea is often drunk with cream, milk or sugar. Any non-dairy cream substitutes generally contain partly hydrogenated oils which are known as all-trans fats. They provoke an increase in the blood of "bad" cholesterol. If you regularly consume large amounts of artificial cream, it can harm the heart.
Excess sugar in your coffee or tea can significantly add calories to the diet.
And sugar, and creamer can reduce the concentration of beneficial antioxidants in caffeine-containing beverages.
Caffeine is not only in hot beverages. Now all over the world produced hundreds of titles sweet drinks with caffeine and power engineering. Young people use them more and more often. If you use more than 500 mg of caffeine in these drinks, you can get many different side effects, including atrial fibrillation or convulsions.
Caffeine is often added to various non-prescription drugs, and children can get it with coffee ice cream or chocolate.
Caffeine is rapidly absorbed into the bloodstream from the gastrointestinal tract and then enters the liver. There he will be cured by specific enzymes. If the enzyme is not all right, caffeine can stay in the blood longer than expected. It is said that when in the research are some mixed results on the caffeine, it may be due to genetic characteristics of those most in liver enzymes.
Brain
Caffeine stimulates mental activity, it helps to cope with lack of sleep and improves the response in the management mechanisms.
Caffeine increases alertness, that is, self-discipline and a willingness to act. Especially appreciated its ability to maintain strength in the work on the night shift.
Headache
Caffeine enhances the action of funds from a headache. It is added to the complex preparations. For this reason, the cancellation of caffeine can trigger a headache. At the bottom there is a link to my article about headache doctor.
parkinsonism
Somehow, inexplicably caffeine protects against the disease.
Alzheimer's disease
Here, too, caffeine has little protective effect.
Psychiatry
In humans, caffeine happens insomnia, irritability, anxiety and other unpleasant mental problems. But depression affects it more good than bad.
Heart
If you do not drink more than three cups of coffee a day, caffeine may protect against myocardial infarction. If you just take a lot of caffeine, it can cause a heart attack. So what medical treatment they will not work.
Endocrinology
Caffeine reduces the risk of diabetes, but for some reason it does so not figured out yet.
Stomach
Caffeine stimulates the bowels and helps with constipation. This effect does not work in Japan and China, because they drink a lot of green tea with a complex composition. Its components counterbalance the effects of caffeine on the intestinal wall. Somehow, it seems, have the effect of tanning.
Caffeine reduces the risk of developing cirrhosis.
Oncology
There was a case when the Americans declared coffee carcinogen. This happened in 2018 in California. The roasted beans were found carcinogens, but human studies increase the risk of cancer is not found. Perhaps, in the coffee many useful antioxidants that protect against cancer. Until now, a clear answer was not given.
Osteoporosis
It seems that the coffee lovers in old age have a slightly better chance of getting a fracture. Tea slightly contrary strengthens bones. There are complex mechanisms and is not always a link between bone mineral density and fracture risk.
Arthritis
Coffee reduces the risk of developing gout.
Urinary incontinence
Caffeine is a diuretic. Everything is clear.
Mortality
Coffee associated with lower mortality from common causes. It is found in many scientific studies. God knows why this is happening ...
Dependence
At the coffee lovers after its cancellation is headache. This physical dependence. But other kinds of dependence among fans until coffee did not seem to find. It turns out that people from the coffee is not pleasure seeking, but rather to support the efficiency and escaping from a headache.
Caffeine had still not announced clearly beneficial or harmful. When there is a problem in the heart, caffeine can die. Therefore, always consult with your doctor about this.
