Most of us just know coffee as that drink we take often at offices…while others may know it as that drink which makes one to be active during working hours.
I am here to tell you that the daily coffee you see or drink all the time has a lot of health benefits
I don’t have doubts at all, that you may have perceived coffee wrongly-as a drink that is bad.
Mine today is to show you those “proven health benefits of coffee” of which No 2 is my favorite.
Coffee is actually very healthy. It is loaded with antioxidants and beneficial nutrients that can improve your health.
The studies show that coffee drinkers have a much lower risk of several serious diseases.
Here are the top 10 evidence-based health benefits of coffee, that have been confirmed in actual human studies.
1. Coffee can improve your energy levels
Coffee can help people feel less tired and increase energy levels.
This is because it contains a stimulant called caffeine, which is actually the most commonly consumed psychoactive substance in the world.
After you drink coffee, the caffeine is absorbed into the bloodstream. From there, it travels into the brain.
In the brain, caffeine blocks an inhibitory neurotransmitter called Adenosine.
When that happens, the amount of other neurotransmitters like norepinephrine and dopamine actually increases, leading to enhanced firing of neurons.
Many controlled trials in humans show that coffee improves various aspects of brain function. This includes memory, mood, vigilance, energy levels, reaction times and general cognitive function.
2. Coffee can help you burn fat
Did you know that caffeine is found in almost every commercial fat burning supplement?
There’s a good reason for that… caffeine is one of the very few natural substances that have actually been proven to aid fat burning.
Several studies show that caffeine can boost the metabolic rate by 3-11%.
Other studies show that caffeine can specifically increase the burning of fat, by as much as 10% in obese individuals and 29% in lean people.
However, it is possible that these effects will diminish in long-term coffee drinkers.
For the sake of weight loss, black coffee is most preferable. It contains the least calories among other coffee. And is not advisable to take more than 6 cups per day.
3. There are essential nutrients in coffee
Coffee is more than just black water. Many of the nutrients in the coffee beans do make it into the final drink.
A single cup of coffee contains:
- Riboflavin (Vitamin B2): 11% of the RDA.
- Pantothenic Acid (Vitamin B5): 6% of the RDA.
- Manganese and Potassium: 3% of the RDA.
- Magnesium and Niacin (B3): 2% of the RDA.
Although this may not seem like a big deal, most people are drinking more than one cup per day. If you drink 3-4, then these amounts quickly add up.
4. Coffee may lower your risk of type II diabetes
Type 2 diabetes is a gigantic health problem, currently afflicting about 300 million people worldwide.
It is characterized by elevated blood sugars in the context of insulin resistance or an inability to secrete insulin.
For some reason, coffee drinkers have a significantly reduced risk of developing type 2 diabetes.
The studies show that people who drink the most coffee have a 23-50% lower risk of getting this disease.
5. Coffee may protect you from alzheimer’s disease and dementia
Alzheimer’s disease is the most common neuro-degenerative disease and the leading cause of dementia worldwide.
This disease usually affects people over 65 years of age.
Unfortunately, there is no known cure for Alzheimer’s.
However, there are several things you can do to prevent the disease from showing up in the first place.
This includes the usual suspects like eating healthy and exercising, but drinking coffee may be incredibly effective as well.
Several studies show that coffee drinkers have up to a 65% lower risk of getting Alzheimer’s disease.
6. Caffeine may lower the risk of parkinson’s disease
Parkinson’s disease is the second most common neuro-degenerative disease, right after Alzheimer’s.
It is caused by death of dopamine-generating neurons in the brain.
Same as with Alzheimer’s, there is no known cure, which makes it that much more important to focus on prevention.
In studies, coffee drinkers have a much lower risk of developing Parkinson’s disease, with a reduction in risk ranging from 32-60%.
7. Coffee appears to have protective effects on the liver
The liver is an amazing organ that carries out hundreds of important functions in the body.
Several common diseases primarily affect the liver, including hepatitis, fatty liver disease and others.
Many of these diseases can lead to a condition called cirrhosis, in which the liver has been largely replaced by scar tissue.
It turns out that coffee may protect against cirrhosis. People who drink up to 4 cups per day have up to an 80% lower risk.
8. Coffee drinkers have a lower risk of some types of cancer
Cancer is one of the world’s leading causes of death and is characterized by uncontrolled growth of cells in the body.
Coffee appears to be protective against two types of cancer… liver cancer 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.
9. Coffee does not cause heart disease and may lower the risk of stroke
It is often claimed that caffeine can increase blood pressure.
This is true, but the effect is small (3-4 mm/Hg) and usually goes away if you drink coffee regularly.
However, the effect may persist in some people, so keep that in mind if you have elevated blood pressure.
That being said, the studies do NOT support the myth that coffee raises the risk of heart disease.
In fact, there is some evidence that women who drink coffee have a reduced risk of heart disease.
Some studies also show that coffee drinkers have a 20% lower risk of stroke.
10. Coffee may help you live longer
Given that coffee drinkers are less likely to get many disease, it makes sense that coffee could help you live longer.
There are actually several observational studies showing that coffee drinkers have a lower risk of death.
In two very large studies, drinking coffee was associated with a 20% lower risk of death in men and a 26% lower risk of death in women, over a period of 18-24 years.
This effect appears to be particularly strong in type II diabetics. In one study, diabetics who drank coffee had a 30% lower risk of death during a 20-year study period.
