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 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 astimulant 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.
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 (3).
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.
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.
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 (15).
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.
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% (18, 19, 20, 21).
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.
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 (27).
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 (28).
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.
