ADH (vasopressin/vasopressin) can increase the "reabsorption" of water by renal tubules and urine collection tubes. There are antidiuretic hormone receptors in renal tubules and urine collection tubes. When the receptor receives ADH released from the posterior pituitary gland and renal tubule, the "reabsorption" of urinary catheter will be enhanced, and the role of caffeine in this mechanism is Robin Hood. Before the recipient receives ADH, it takes ADH away from it (combines with ADH), so that the ADH recipient in the kidney can't combine with ADH, and if ADH can't be obtained, the "reabsorption" of renal tubule-urinary catheter will not be enhanced, so the urine volume will increase!
"What we usually say about coffee refers to pure coffee, that is, coffee without any other substances." Fu Changming said that it is low in calories and contains a variety of nutrients. Moderate drinking is good for health.
1 Reduce the risk of cancer.
A study published in the American Journal of Clinical Gastroenterology and Hepatology found that drinking coffee every day can reduce the risk of primary liver cancer (the most common type of liver cancer) by 40%. Other studies have shown that drinking coffee regularly can reduce the risk of ovarian cancer in women.
2 enhance memory.
Dr. Jacklin London, a senior nutritionist at Mount Sinai Hospital in new york, USA, said that moderate intake of caffeine is good for both short-term memory and long-term memory, which helps to prevent cognitive decline.
3 protect the cardiovascular system.
After studying 25,000 subjects, Korean researchers found that people who drink 3 to 5 cups of coffee a day (about 200 ml per cup) have a lower risk of cardiovascular disease. A study by the National Cancer Research Center of Japan shows that people who drink 1 cup of coffee every day have a lower risk of death from stroke than those who don't drink coffee.
4 prevent diabetes.
A study of 6.5438+0.26 million people conducted by Harvard University in the United States shows that people who drink coffee regularly have a lower risk of developing type 2 diabetes.
5 contribute to longevity.
An academic paper published by a medical professor at Indiana University shows that the death rate of people who insist on drinking coffee is lower than that of ordinary people. Fu Changming also said that Chengmai County, the hometown of longevity in Hainan, is rich in coffee, with an average life expectancy of 77.79 years, which is 6.59 years longer than the national average. All the long-lived old people here have the habit of drinking pure coffee. In addition, Dr. Frank Hu, a professor of nutrition and epidemiology at Harvard School of Public Health, found that drinking coffee can reduce the risk of fatty liver, reduce the risk of suicide by 50%, promote digestion and prevent constipation.
