TEXTO:

Coffee isn’t just warm and energizing, it may also

be extremely good for you. In recent years and decades,

scientists have studied the effects of coffee on various

aspects of health and their results have been nothing

[5] short of amazing.

Coffee doesn’t just keep you awake, it may literally

make you smarter as well. The active ingredient in coffee

is caffeine, which is a stimulant and the most commonly

consumed psychoactive substance in the world.

[10] Caffeine’s primary mechanism in the brain is blocking

the effects of an inhibitory neurotransmitter called

Adenosine. By blocking the inhibitory effects of

Adenosine, caffeine actually increases neuronal firing in

the brain and the release of other neurotransmitters like

[15] dopamine and norepinephrine. Many controlled trials have

examined the effects of caffeine on the brain,

demonstrating that caffeine can improve mood, reaction

time, memory, vigilance and general cognitive function.

There’s a good reason why you will find caffeine in

[20] most commercial fat burning supplements. Caffeine,

partly due to its stimulant effect on the central nervous

system, both raises metabolism and increases the

oxidation of fatty acids. Caffeine can also improve athletic

performance by several mechanisms, including by

[25] mobilizing fatty acids from the fat tissues.

Type II diabetes is a lifestyle-related disease

that has reached epidemic proportions, having increased

10-fold in a few decades and now afflicting about 300

million people. In observational studies, coffee has been

[30] repeatedly associated with a lower risk of diabetes. The

reduction in risk ranges from 23% all the way up to 67%.

A massive review article looked at 18 studies with a total

of 457.922 participants. Each additional cup of coffee

per day lowered the risk of diabetes by 7%. The more

[35] coffee people drank, the lower their risk.
