Thanks to its high levels of antioxidants, coffee seems to be pretty healthy.
Here are the top 13 scientific benefits of coffee:
Improve energy levels and make you smarter
Many controlled studies in humans show that coffee improves various aspects of brain function — including memory, mood, vigilance, energy levels, reaction times and general mental function (7, 8, 9).
Helps burn fat
Several studies show that caffeine can boost your metabolic rate by 3–11% (10, 11).
Other studies indicate that caffeine can specifically increase fat burning by as much as 10% in obese individuals and 29% in lean people (12).
Improves physical performance
This is the fight-or-flight hormone, which prepares your body for intense physical exertion.
Given these effects, it’s unsurprising that caffeine can improve physical performance by 11–12%, on average (20, 29).
Contains essential nutrients
Many of the nutrients in coffee beans make their way into the finished brewed coffee.
A single cup of coffee contains (21):
Riboflavin (vitamin B2): 11% of the Reference Daily Intake (RDI).
Pantothenic acid (vitamin B5): 6% of the RDI.
Manganese and potassium: 3% of the RDI.
Magnesium and niacin (vitamin B3): 2% of the RDI.
May lower your risk of Type 2 diabetes
Helps prevent memory loss
Several studies show that coffee drinkers have up to a 65% lower risk of Alzheimer’s disease (28, 29).
May lower risk of Parkinson’s
Studies show that coffee drinkers have a much lower risk of Parkinson’s disease, with a risk reduction ranging from 32–60% (30, 31, 32, 33).
In this case, the caffeine itself appears to be beneficial, as people who drink decaf don’t have a lower risk of Parkinson’s (34).
May protect your liver
Interestingly, coffee may protect against cirrhosis — people who drink 4 or more cups per dayhave up to an 80% lower risk (35, 36, 37).
In a Harvard study published in 2011, women who drank 4 or more cups of coffee per day had a 20% lower risk of becoming depressed (38).
May lower risk of certain types of cancer
Coffee appears to be protective against two types of cancer: liver and colorectal cancer.
Liver cancer is the third leading cause of cancer death in the world, while colorectal cancer ranks fourth (40).
Similarly, one study in 489,706 people found that those who drank 4–5 cups of coffee per day had a 15% lower risk of colorectal cancer (43).
