Coffee is actually very healthy.
It is loaded with antioxidants and beneficial nutrients that can improve your health.
The studies show that coffee drinkers have a
much lower risk of several serious diseases.
Here are the top 13 evidence-based health benefits of coffee, that have been confirmed in actual human studies.
1. Coffee Can Improve Energy Levels and Make You Smarter
Coffee can help people feel less tired and increase energy levels (
1,
2).
This is because it contains a stimulant called
caffeine, which is actually the most commonly consumed psychoactive substance in the world (
3).
After you drink coffee, the caffeine is absorbed into the bloodstream. From there, it travels into the brain (
4).
In the brain, caffeine blocks an inhibitory neurotransmitter called
Adenosine.
When that happens, the amount of other neurotransmitters like norepinephrine and dopamine actually increases, leading to enhanced firing of neurons (
5,
6).
Many controlled trials in humans show that coffee improves various aspects of brain function. This includes memory, mood, vigilance, energy levels, reaction times and general cognitive function
