Coffee is one of the healthiest drinks in the world.

Coffee is not only a black drink containing caffeine, it is rich in a variety of beneficial substances. Several studies have shown that coffee drinkers live longer and are less likely to develop Alzheimer's disease and diabetes.

Coffee is a powerful antioxidant. After being soaked in hot water, coffee powder can stimulate all kinds of beneficial substances contained in it. The best known of these substances is caffeine, but in addition, there are many beneficial ingredients that have not yet been discovered by scientists. Most of these ingredients have the function of antioxidation and can protect cells from free radicals.

It is well known that oxidation is one of the leading culprits of aging, cancer and heart attack. Coffee can effectively help the body resist oxidation. In the western diet, coffee is considered to be the most antioxidant food, and its effect is even more than that of some fruits and vegetables. When you drink coffee, you are not only consuming caffeine, but you also get a lot of beneficial substances, including extremely important antioxidants.

Several surveys show that people who drink coffee are more likely to live longer. The most authoritative of these studies said that by tracking 400000 people between the ages of 50 and 71, the researchers found that coffee drinkers had a much lower mortality rate than non-coffee drinkers over the next 12 to 13 years.

As the picture shows, the more people drink coffee, the lower the death rate. It peaked at 4-5 cups a day, and the death rate of men who drank this amount of coffee per day decreased by 12% and that of women by 16%. But the study also said that drinking more than six cups of coffee a day had no more effect on mortality.

Researchers have found that even if you don't drink much coffee, it can reduce mortality. People who drink one cup of coffee a day have a 5-6% lower mortality rate than the average person. This shows that drinking coffee can increase the chances of longevity.

These figures may not seem large, but as coffee consumption becomes more and more popular, the impact of coffee on people will become more significant.

In an in-depth investigation into the causes of death, scientists found that coffee drinkers were less likely to die from infection, trauma, respiratory diseases, diabetes, stroke and heart disease than non-coffee drinkers.

The positive effects of coffee on human health are not limited to caffeine, but also have similar effects.

Of course, the above research is limited to scientific observation and inference, and does not prove that coffee is the cause of longevity. However, drinking coffee regularly can definitely be regarded as a kind of health protection. We can at least be sure that coffee is not poison.

Other studies on the relationship between coffee and human health have achieved the same results. In fact, such research has been going on for many years. Other studies have shown that coffee drinking by pregnant women can reduce the risk of death in premature babies.

If we talk about the relationship between coffee and disease, we will find that coffee drinkers are far less likely to develop Alzheimer's disease, Parkinson's disease, type 2 diabetes and hepatitis than non-coffee drinkers.

Research from Harvard University in the United States also shows that drinking coffee can make people happier, thus reducing the risk of depression and suicidal tendencies.

All in all, drinking coffee can not only prolong life, but also improve health. Coffee is definitely one of the healthiest drinks in the world.
