Some compounds in healthy 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 7.6lb in 1983 to 7.4lb in 1985, mainly due to a large number of medical articles condemning coffee.

Coffee has become a villain with many side effects, and coffee is considered to be the number one enemy affecting American public health. Now, under the advocacy of Starbucks, which has thousands of coffee shops, coffee has become the number one drink not only in the United States, but also in the world. Modern scientific research has gradually begun to deny the unfair criticism of coffee and the inadequate study of caffeine. The latest research shows that coffee not only contains caffeine, but also contains many useful compounds, proper consumption of 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 regularly in moderation, which not only saves the coffee industry, but also makes people smarter, happier and healthier. Two soft drink companies were accused of mixing several ingredients in their drinks to form a carcinogenic chemical, and later agreed to change the formula and return carcinogenic drinks bought by consumers. Independent laboratory tests found that one Vault Zero sample contained 13ppb benzene, while other drinks were between 5-10ppb. In the United States, benzene content is the safe upper limit at 5ppt, while the World Health Organization limits it to 10ppt. Less than a year after Vault Zero operated in the United States, it was involved in today's lawsuit against Coca-Cola over benzene. Benzene is listed as a carcinogen by health authorities around the world, although the content in the drink does not pose a health hazard. Experts from the US Food and Drug Administration have revealed for the first time that benzene still exists in some drinks and exceeds the safety limit for drinking water in the United States, and the legal debate over benzene in soft drinks has been going on for six months. However, FDA and the American soft drinks Association claim that this is not harmful to consumers' health. Four beverages exceeding the World Health Organization's benzene limit have been recalled in the UK. Food safety authorities and soft drink companies have once again stated that low levels of benzene are not harmful to consumers' health. The American Beverage Association said: after years of repeated review, the FDA concluded that low levels of benzene are not harmful to consumers' health.

Dr. Winkelmayer and his colleagues from Harvard University in the United States examined questionnaires from two independent studies involving 155594 people in 1990-1991 and 2002-2003 and found that some women with normal blood pressure later developed high blood pressure. After complex statistical studies, they found that these women regularly drank cola instead of coffee and tea. The results show that there is no relationship between coffee and high blood pressure. Only about 7% of women who drank more than three cups of coffee a day had high blood pressure compared with women who drank little or no coffee. However, there was a significant relationship between Coke consumption and high blood pressure in elderly and young women. Drinking four tins of sugary cola a day increased the risk of high blood pressure by 28% and 44% compared with women who rarely or never drank it. The authors stress that there is no biological evidence for the relationship between cola and high blood pressure. The report recommends a wide range of studies, including the effects of caramel in all colas and high fructose corn syrup in sweetened colas. The study found that high fructose corn syrup with a content of more than 55% was associated with an increase in the incidence of obesity and weight-related diseases over the past 10 years. The same results have been found in animal experiments, where animals fed large amounts of fructose usually cause high blood pressure. Hypertension is considered to be a risk factor for coronary heart disease and stroke. There are also records that consuming large amounts of caffeine every day can lead to a rise in blood pressure. 200-250 mg of caffeine is equivalent to 2-3 cups of coffee, which can cause increases in systolic and diastolic blood pressure. Although caffeine drinkers have a certain tolerance to elevated blood pressure, the results show that this tolerance may be different even among people who drink coffee every day.
