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 short of amazing.
Here are 3 reasons why coffee may actually be one of the healthiest beverages on the planet.
1. Coffee Can Make You Smarter
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.
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 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.
Bottom Line: Caffeine potently blocks an inhibitory neurotransmitter in the brain, leading to a net stimulant effect. Controlled trials show that caffeine improves both mood and brain function.
2. Coffee Can Help You Burn Fat and Improves Physical Performance
There’s a good reason why you will find caffeine in 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 mobilizing fatty acids from the fat tissues
In two separate meta-analyses, caffeine was found to increase exercise performance by 11-12% on average.
Bottom Line: Caffeine raises the metabolic rate and helps to mobilize fatty acids from the fat tissues. It can also enhance physical performance.
3. Coffee May Drastically Lower Your Risk of Type II Diabetes
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.
This disease is characterized by high blood glucose levels due to insulin resistance or an inability to produce insulin.
In observational studies, coffee has been 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 coffee people drank, the lower their risk.
Bottom Line: Drinking coffee is associated with a drastically reduced risk of type II diabetes. People who drink several cups per day are the least likely to become diabetic.
