Many people start their morning with coffee, invite colleagues and friends to it, buy it on a walk in the park. Here are four benefits of the drink and useful information about how often you can drink it.
Benefits of coffee
Gives energy
Coffee is not called an invigorating drink for nothing. The caffeine it contains, when it gets into the brain, begins to block adenosine, a nucleoside that, among other functions, regulates sleep mechanisms.
Caffeine "replaces" adenosine, and neurons do not receive a signal of fatigue, and a person perceives this as a surge of energy. The effect lasts for about 2-4 hours.
Saturates the body with antioxidants
It is from coffee, and not from fruits and vegetables, that modern man gets the main share of antioxidants. They suppress oxidative processes in the body, help cells to recover and, as a result, slow down aging, strengthen the immune system, reduce the risk of tumors, heart and vascular problems, and disorders of the nervous and immune systems.
Reduces the risk of diabetes
Diabetes is one of the most common and dangerous diseases. Coffee affects insulin production, glucose absorption and thus regulates blood sugar levels. As a result of several experiments, in which almost half a million people participated in total, it was found that 3 cups of the invigorating drink a day reduce the risk of developing diabetes by 25%.
Protects against Parkinson's and Alzheimer's diseases
Parkinson's and Alzheimer's are among the most common age-related diseases that, unfortunately, cannot be cured. However, they can be prevented, including with the help of coffee. The drink contains phenylindanes - compounds that prevent the accumulation of proteins associated with Parkinson's and Alzheimer's.
How many cups of coffee can you drink daily
Healthy people are recommended to drink no more than 300 ml of coffee (instant or natural), which is about 3 cups. But you should focus on your well-being. If it worsens after the second cup, then you should limit yourself to one.
It is better to drink coffee in the first half of the day to avoid problems with sleep. It is not advisable for children, teenagers, and pregnant women to drink the drink.
