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 7 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.
4. Coffee May Lower
Your Risk of Alzheimer’s and Parkinson’s
Not
only can coffee make you smarter in the short term, it may also protect your
brain in old age.Alzheimer’s
disease is the most common neurodegenerative disorder in the world and a
leading cause of dementia.In
prospective studies, coffee drinkers have up to a 60% lower risk of Alzheimer’s
and dementia Parkinson’s
is the second most common neurodegenerative disorder, characterized by death of
dopamine-generating neurons in the brain. Coffee may lower the risk of
Parkinson’s by 32-60%
Bottom Line: Coffee is associated with a much
lower risk of dementia and the neurodegenerative disorders Alzheimer’s and
Parkinson’s.
5. Coffee May be
Extremely Good For Your Liver
The
liver is a remarkable organ that carries out hundreds of vital functions in the
body.It
is very vulnerable to modern insults such as excess consumption of alcohol and fructose.Cirrhosis
is the end stage of liver damage caused by diseases like alcoholism and
hepatitis, where liver tissue has been largely replaced by scar tissue.Multiple
studies have shown that coffee can lower the risk of cirrhosis by as much as
80%, the strongest effect for those who drank 4 or more cups per day.
6. Coffee May
Decrease Your Risk of Dying
Many
people still seem to think that coffee is unhealthy.This
isn’t surprising though, since it is very common for conventional
wisdom to be at exact odds with what the actual studies say.In
two very large prospective epidemiological studies, drinking coffee was
associated with a lower risk of death by all causes .This
effect is particularly profound in type II diabetics, one study showing that
coffee drinkers had a 30% lower risk of death during a 20 year period .
Bottom Line: Coffee consumption has been
associated with a lower risk of death in prospective epidemiological studies,
especially in type II diabetics.
7. Coffee is Loaded
With Nutrients and Antioxidants
Coffee
isn’t just black water.Many
of the nutrients in the coffee beans do make it into the final drink, which
actually contains a decent amount of vitamins and minerals.A
cup of coffee contains §
6% of the RDA for Pantothenic Acid (Vitamin B5).
§
11% of the RDA for Riboflavin (Vitamin B2).
§
2% of the RDA for Niacin (B3) and Thiamine
(B1).
§
3% of the RDA for Potassium and Manganese.
May not seem like much, but if you drink several cups of coffee per day then this quickly adds up.But this isn’t all. Coffee also contains a massive amount of antioxidants.In fact, coffee is the biggest source of antioxidants in the western diet, outranking both fruits and vegetables combined

the modern diet.
Take Home Message
Even
though coffee in moderate amounts is good for you, drinking way too much
of it can still be harmful.I’d
also like to point out that many of the studies above were epidemiological in
nature. Such studies can only show association, they can not prove
that coffee caused the effects.To
make sure to preserve the health benefits, don’t put sugar or anything nasty in
your coffee! If it tends to affect your sleep, then don’t drink it after 2 pm.At
the end of the day, it does seem quite clear that coffee is NOT the villain it
was made out to be.If
anything, coffee may literally be the healthiest beverage on the planet.
