Is drinking coffee good or bad?

Is coffee the next super food or the next source of public health hazards? It depends on who you ask. If you look at the recent news or research, you will find that coffee can fight heart disease, reduce the incidence of breast cancer, and reduce Alzheimer's disease. But if you do more research, you will find that coffee also increases your risk of contracting various diseases.

Why do the results contradict each other? Part of the reason may be that some ingredients in coffee are good for the body, while others are harmful. Coffee, for example, contains antioxidants that help cells resist damage caused by unstable molecules called free radicals, which are linked to cancer. At the same time, some researchers speculate that drinking hot coffee may increase people's risk of developing esophageal cancer because hot coffee can scald the esophagus.

People make coffee in many ways, and the way you make coffee may change the way it behaves in your body. In the case of dripping coffee, this method flushes away some lipids in coffee beans, including caffeine alcohol and coffee white fat. These compounds increase your body's levels of low-density lipoprotein, also known as bad cholesterol. For this reason, drip coffee may be better for heart health than coffee made from French filter pots.

Lifestyle factors can also influence the results of the study. Studies have shown that people who drink more coffee usually smoke and drink, and they are usually under a lot of stress, and these habits can affect the positive effects of coffee drinking habits on the human body. Even seemingly harmless habits, such as adding milk or sugar to coffee, can confuse the results.

If you don't know if you should keep drinking coffee, don't worry, most public health experts believe that the benefits of coffee outweigh the disadvantages. The strongest view comes from a 2014 integration analysis that integrates studies on the relationship between long-term coffee consumption and cancer, heart disease and mortality between 1996 and 2013. Overall, coffee is beneficial. Don't worry about it.
