Black coffee can make your mood clear and reduce depression.
Coffee stimulates neurotransmitters such as dopamine, serotonin and norepinephrine produced by the central nervous system, which can increase positive emotional response, avoid depression and reduce suicide rate. 20 1 1 A study on American women confirmed this argument.
There has been a debate about coffee. What is certain, however, is that caffeine, vitamins B2, B5, manganese, potassium and magnesium in black coffee are all beneficial to human body at a proper concentration. Unless there are symptoms of high cholesterol and caffeine sensitivity, as long as the intake is moderate (the Ministry of Health recommends that caffeine intake should not exceed 300mg per day), it is beneficial and harmless to the human body. Finally, I would like to remind you that in order to drink healthily, you should pay attention to your daily caffeine intake.
