Is it healthy to drink coffee for preventable diseases?

"I often tell my patients that if you like coffee, drink as much as you can." Said Peter Martin, dean of the School of Coffee Studies at Vanderbilt University. As for how to control the amount of coffee you drink, Martin believes that if coffee has affected your sleep, then you should drink one less cup, which should be the last cup of the day. "if you control it properly, coffee won't have any negative effect on you. On the contrary, coffee is good for health. "

The medical community has a slightly conservative attitude towards the magical effects of coffee. The American Medical Association believes that as long as people have a healthy lifestyle, drinking a moderate amount of tea or coffee will not affect people's health. I personally think that such an evaluation is a desecration to the hard work of countless scholars who have been devoted to exploring the effects of coffee on human health in recent years. Their research results not only overturn the long-standing view that coffee is harmful to the human body, but also reveal to the world many benefits that long-term drinking coffee can bring to people. Nowadays, new discoveries such as "drinking coffee can prevent Alzheimer's disease" and "drinking coffee can protect the liver" have led people to build a new understanding of coffee again and again. But the benefits of drinking coffee are much more than that. Recent studies have found that caffeine is not the only beneficial substance in coffee. Coffee is likely to become an important source of nutrients in the future.

Coffee, as a magic elixir, can reduce the risk of developing type 2 diabetes, according to a new study. The results were officially published in the December issue of the American Journal of Nutrition and Health (American Journal of Clinical Nutrition).

"when it comes to coffee, people think of caffeine. But in fact, coffee contains much more nutrients than caffeine. " Martin said. He also points out that the latest research has confirmed that caffeine does not pose a cardiovascular burden. In June, a 10-year follow-up study found that long-term, quantitative consumption of coffee did not increase the risk of cardiovascular disease. On the contrary, when the daily consumption reaches 4 cups, coffee will also have a protective effect on the cardiovascular system. The study also found that coffee has no negative impact on cardiovascular health unless you drink more than 10 cups a day.

In addition, caffeine has been found to relieve pain. A study in September found that coffee can effectively reduce back, neck and shoulder pain caused by long-term sitting. Participants in the study all said that drinking coffee did relieve pain and stiffness in these areas. The study data also show that coffee can not only reduce physical pain, its psychological pain reduction effect is more obvious. Other related studies have also shown that drinking coffee can make people more positive and optimistic, and can eliminate stress and reduce the risk of depression.

So is caffeine the only medicine we can trust? In October, 554 adults from Japan volunteered for a scientific study to explore the effects of coffee and tea, two globally recognized caffeine-rich drinks, on coronary artery disease, stroke and type 2 diabetes. The results show that only coffee can reduce the risk of these diseases. Data show that coffee can effectively reduce the content of triglycerides in human blood.

So in addition to caffeine, what other beneficial substances do we eat while drinking coffee? I can only say that many antioxidants found so far, including phenol, chlorogenic acid and quinolide, are only a small part of the thousands of nutrients in coffee, and there are still many to be found and confirmed. According to research, scientists have found that dripping coffee can effectively increase the level of good cholesterol in the body and control the content of harmful cholesterol. The benefits of coffee are numerous. Now we can at least be sure that drinking coffee is good for human health.

Some people say coffee contains carcinogens, but science has shown that only expired, spoiled beans contain trace carcinogens. Coffee is absolutely harmless as long as the beans are fresh enough. In fact, coffee not only does not cause cancer, but also prevents cancer. In May 2011, a team of researchers in public health at Harvard University conducted an experiment that showed that long-term coffee consumption could effectively prevent prostate cancer. In another study of the effects of coffee on cancer in July, it was found that increasing caffeine intake could inhibit the growth of cancer cells. The study also showed that caffeine was most effective in preventing cancer when drinking more than six cups of coffee a day.

At the same time, coffee has been shown to prevent rectal cancer. In June, the American Nutrition Association conducted a follow-up study involving more than 500000 volunteers. Studies have shown that caffeine has the most obvious anti-cancer effect. Decaffeinated coffee is not effective, but it can also prevent cancer. In addition, in January, another comprehensive study of 16 individual studies found that caffeine was effective in preventing endometrial cancer. In 2011, a Swedish study on the effect of coffee on the risk of breast cancer in postmenopausal women showed that drinking more than five cups of coffee a day reduced the risk of breast cancer in that age group.

There are numerous magical effects of caffeine. Here are some of the best-known benefits of drinking coffee:

If you have fatty liver: a study last December showed that drinking coffee can prevent the risk of liver fibrosis.

If you're driving a long distance: in February, scientists conducted an experiment. In the experiment, participants were asked to drive on the highway for two hours, then take a break, and then drive for another two hours. Those who had had coffee on the way were shown to drive at a more reasonable speed, have clearer minds and feel less tired. At the same time, the experiment also confirmed that people who drank coffee performed better in sports, especially in competitions (caffeine can act as a stimulant).

If you want to improve the effectiveness of physical training: a study in October showed that caffeine can improve the effectiveness of physical training. In addition, another study published in 2008 found that caffeine can help people who are addicted to alcohol keep a clear head.
