Each additional cup of coffee per day lowered the risk of type 2 diabetes by 7%. The more coffee people drank, the lower their risk was ( 15 ). Drinking coffee is associated with a drastically reduced risk of type 2 diabetes. People who drink several cups per day are the least likely to develop diabetes.
Coffee isn’t just tasty 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. 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 also make you smarter.
The active ingredient in coffee is caffeine, which is a stimulant and the most commonly consumed psychoactive substance in the world.
Caffeine works in your brain by 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 (1, 2Trusted Source).
Many controlled studies have examined the effects of caffeine on the brain, demonstrating that caffeine can temporarily improve mood, reaction time, memory, vigilance and general brain 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.
Caffeine, partly due to its stimulant effect on the central nervous system, both raises metabolism and increases the oxidation of fatty acids (4Trusted Source, 5Trusted Source, 6Trusted Source).
It can also improve athletic performance in several ways, including by mobilizing fatty acids from the fat tissues (7Trusted Source, 8Trusted Source).
In two separate meta-analyses, caffeine was found to increase exercise performance by 11–12%, on average
(9Trusted Source, 10).
3. Coffee May Drastically Lower Your Risk of Type 2 Diabetes
Type 2 diabetes is a lifestyle-related disease that has reached epidemic proportions. It has increased 10-fold in a few decades and now afflicts 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 type 2 diabetes. The reduction in risk ranges from 23% all the way up to 67% (11Trusted Source, 12Trusted Source, 13, 14Trusted Source).
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 type 2 diabetes by 7%. The more coffee people drank, the lower their risk was (15Trusted Source).
4. Coffee May Lower Your Risk of Alzheimer’s and Parkinson’s
Not only can coffee make you smarter in the short term, but 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 (16).
Parkinson’s is the second most common neurodegenerative disorder, characterized by the death of dopamine-generating neurons in the brain. Coffee may lower your risk of Parkinson’s by 32–60% (17, 18Trusted Source, 19, 20).
5. Coffee May Be Extremely Good for Your Liver
The liver is a remarkable organ that carries out hundreds of vital functions in your body.
It is vulnerable to modern dietary pitfalls, such as consuming too much alcohol or 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 your risk of cirrhosis by as much as 80%. Those who drank 4 or more cups per day felt the strongest effect (21, 22, 23Trusted Source).
Coffee may also lower your risk of liver cancer by around 40% (24, 25).
