Which compounds in coffee are good for your health?

In 1980, the import of natural coffee in the United States reached 3.872 billion US dollars, and the per capita coffee consumption in the United States began to decline in 1983, from 7.6lbs per year in 1983 to 7.4lbs in 1985. It is assumed that coffee is being condemned because of a few medical articles. Coffee has become a much more negative role, and coffee is regarded as a first-class enemy that affects the health of the American public. At that time, at the initiative of the Starbucks chain with thousands of coffee shops, coffee became not only the United States, but also the number one drink in the world. Contemporary scientific research has gradually denied unfair comments on coffee and inadequate research on caffeine. The latest research shows that coffee not only contains caffeine, but also contains many effective compounds, suitable for drinking coffee is not only safe, but also good for health, can prevent some diseases. It is for this reason that coffee drinkers in the United States still drink coffee in moderation, which not only gives money to the coffee industry, but also makes people smarter, more lucky, and healthier. Two soft drink companies, accused of alienating the use of several elements in drinking guesses that could cause a carcinogenic chemical, agreed to change the formula and return drinks containing carcinogenic bodies bought by consumers. Independent laboratory tests create a Vault Zero sample that contains 13ppb benzene, while other drinks are between 5-10ppb. In the United States, benzene content is the upper limit of insurance in 5ppt, while the national health structure will be limited to 10ppt. Less than a year after Vault Zero operated in the United States, it was embroiled in a current lawsuit against Coca-Cola over benzene. Benzene is listed as a carcinogen by the global health authority, of course, the content of the drink will not cause the death of health. Experts from the US Food and Drug Administration first revealed that benzene still exists in some drinks and exceeded the safe lower limit of drinking water in the United States, and then the legal debate on benzene in soft drinks has been going on for six months. However, FDA and the American soft drinks Association claim that there is no harm to consumers' health. In the UK, four beverages have been dispatched that exceed the national limits on benzene content in sanitary distribution. Food safety agencies and soft drink companies once again claim that low levels of benzene are not harmful to consumers' health. The American Beverage Association said: FDA has been repeatedly reviewed over the years that low levels of benzene are harmful to consumers' health.

Dr Winkelmayer and his colleagues from Harvard University in the United States examined two self-administered examination papers taken by 155594 people between 1990-1991 and 2002-2003, creating women with previously abnormal blood pressure who later developed high blood pressure. Through complex statistical research, they created these housewives to regularly drink cola instead of coffee and tea. The results suggest that there is no link between coffee and hypertension. Women who drank more than three cups of coffee a day had high blood pressure compared with women who drank little or no coffee, or only 7% of women had high blood pressure. However, among the elderly and young housewives, there was a significant relationship between Coke consumption and high blood pressure. Drinking 4 tins of sugary cola drinks a day compared with housewives who rarely or never drank them increased the contusions of high blood pressure by 28% and 44%. The authors exaggerate that their study shows no biological evidence for the relationship between cola and high blood pressure. It is suggested that various studies should be conducted to collect the effects of caramel in all colas and high fructose corn syrup in sweetened cola on the human body. The study found that high fructose corn syrup with a content of more than 55% had nothing to do with the increased incidence of obesity and weight-related diseases over the past 10 years. The opposite has also been found in plant practice, where plants fed with large amounts of fructose usually cause high blood pressure. High blood pressure is thought to be the cause of coronary heart disease and stroke. There is also a documented explanation that consuming large amounts of caffeine every day can cause blood pressure to rise. 200-250 mg of caffeine is equivalent to 2-3 cups of coffee, which can cause systolic and diastolic blood pressure to rise. Although people who drink caffeine may not necessarily have a tolerance to elevated blood pressure, the consequences of the study have revealed that this tolerance may be different even among those who drink coffee every day.
