Coffee is one of the world’s most popular beverages.
Thanks to its high levels of antioxidants and beneficial nutrients, it also seems to be quite healthy.
Studies show that coffee drinkers have a much lower risk of several serious diseases.
Helps Burn Fat
Caffeine is found in almost every commercial fat-burning supplement — and for good reason. It’s one of the few natural substances proven to aid fat burning.
Several studies show that caffeine can boost your metabolic rate by 3–11%.
Other studies indicate that caffeine can specifically increase fat burning by as much as 10% in obese individuals and 29% in lean people.
However, it’s possible that these effects diminish in long-term coffee drinkers.
Contains Essential Nutrients
Many of the nutrients in coffee beans make their way into the finished brewed coffee.
A single cup of coffee contains.
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.
Though this may not seem like a big deal, most people enjoy several cups per day - allowing these amounts to quickly add up.
May Lower Your Risk of Type 2 Diabetes
Type 2 diabetes is a major health problem, currently affecting millions of people worldwide.
It’s characterized by elevated blood sugar levels caused by insulin resistance or a reduced ability to secrete insulin.
For some reason, coffee drinkers have a significantly reduced risk of type 2 diabetes.
Studies observe that people who drink the most coffee have a 23–50% lower risk of getting this disease. One study showed a reduction as high as 67%.
According to a large review of 18 studies in a total of 457,922 people, each daily cup of coffee was associated with a 7% reduced risk of type 2 diabetes.
May Lower Risk of Certain Types of Cancer
Cancer is one of the world’s leading causes of death. It is characterized by uncontrolled cell growth in your body.
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.
Studies show that coffee drinkers have up to a 40% lower risk of liver cancer.
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.
Doesn’t Cause Heart Disease and May Lower Stroke Risk
It’s often claimed that caffeine can increase your blood pressure.
This is true, but with a rise of only 3–4 mm/Hg, the effect is small and usually dissipates if you drink coffee regularly.
However, it may persist in some people, so keep that in mind if you have elevated blood pressure.
That being said, studies don’t support the idea that coffee raises your risk of heart disease.
On the contrary, there is some evidence that women who drink coffee have a reduced risk.
Some studies also show that coffee drinkers have a 20% lower risk of stroke.
Anti-Oxidant
That’s because coffee is quite high in antioxidants. Studies show that many people get more antioxidants from coffee than from fruits and vegetables combined.
In fact, coffee may be one of the healthiest beverages on the planet.
Physical Improvement
Caffeine stimulates your nervous system, signaling fat cells to break down body fat.
But it also increases epinephrine (adrenaline) levels in your blood.
This is the fight-or-flight hormone, which prepares your body for intense physical exertion.
Caffeine breaks down body fat, making free fatty acids available as fuel.
Given these effects, it’s unsurprising that caffeine can improve physical performance by 11–12%, on average.
Therefore, it makes sense to have a strong cup of coffee about half an hour before you head to the gym.
Protect Your Liver
Your liver is an amazing organ that carries out hundreds of important functions.
Several common diseases primarily affect the liver, including hepatitis, fatty liver disease and many others.
Many of these conditions can lead to cirrhosis, in which your liver is largely replaced by scar tissue.
Interestingly, coffee may protect against cirrhosis — people who drink 4 or more cups per day have up to an 80% lower risk.
