Coffee is known for boosting physical energy and mental concentration so it’s a popular drink among students, young professionals, and older adults. But it also has many health benefits beyond its energy-boosting property!
According to numerous scientific studies, coffee drinkers are less likely to develop chronic degenerative diseases like Parkinson’s disease, Type 2 diabetes, and dementia in comparison with non-coffee drinkers. Coffee drinkers are also less likely to develop cardiovascular diseases, such as strokes and heart rhythm issues.
But emphasis must also be made that coffee hasn’t been proven to completely prevent chronic degenerative conditions. Drinking excessive amounts of coffee also has its adverse effects, such as heart palpitations, so moderation in consumption is always advised. Here are the 13 Incredible health benefits of coffee based on scientific studies
#1. Lower Risk for Type 2 Diabetes
The data regarding the possibility that regular coffee consumption can lower the risk for Type 2 diabetes  is solid. In a study conducted by The American Chemical Society, the researchers concluded that people who consumed four or more cups of coffee daily have a reduced risk of Type 2 diabetes by as much as 50% 
With every added cup of coffee consumed, the risk becomes even lower by another 7% . There’s also evidence that both regular coffee and decaffeinated coffee can reduce said risk. The benefit also seems to apply regardless of the person’s weight, gender, and geographic location, perhaps a proof that coffee is indeed a universal drink.
Coffee is the whole package because of its combination of antioxidants, which aids in the prevention of tissues damage by free radicals, as well as minerals like chromium and magnesium. Both of these minerals play crucial roles in the body’s proper use of insulin, the hormone that controls blood glucose levels.
But don’t drink too much coffee either. The dark brew also contains caffeine, which can increase blood pressure and adrenaline levels resulting in side effects like heart palpitations.
#2. Counter the Risk Factors Associated with Heart Disease and Stroke
Coffee may also lower the risk for cardiovascular diseases, particularly heart disease and stroke, by countering many of their risk factors.
First, it reduces the risk for Type 2 diabetes, as previously mentioned. Emphasis must be made that people who have the disorder have higher risks for strokes and heart disease.
Second, it has been closely linked to reduced risks for disturbances in heart rhythm, yet another risk factor for cardiovascular diseases. To be more specific, these disturbances increase the risk of stroke and heart disease for men, as well as increased risk of strokes for women .
Coffee may increase your blood pressure levels after drinking it but it will resolve on its own. Such a side effect is minor in light of studies suggesting that it counters the risk factors associated with cardiovascular diseases.
#3. Linked to Decreased Risk of Liver Cancer
While evidence of coffee’s protection against cancer isn’t as strong as in Type 2 diabetes, there’s still consistent evidence where liver cancer and liver cirrhosis are concerned. The scientific studies  are consistent in their findings that high coffee consumption can be strongly linked to decreased risk for these liver diseases.
Scientists have yet to find how coffee works in the protection of the liver. The studies also don’t show a definite cause-and-effect relationship between the two.
In a study of nearly 490,000 individuals , the researchers found that people who drank 4-5 cups daily had a 15% reduced risk of colorectal cancer, too.
In yet another study of coffee’s effects in relation to cancer , the researchers concluded that women who consumed three or more cups of coffee per day were significantly less likely to have skin cancer than non-drinkers or people who drank less. The combined teams of Harvard Medical School and Brigham and Women’s Hospital studied nearly 113,000 men and women for 20 years.
#4.Protection Against Gout
In a Nurses’ Health Study where researchers analyzed the lifestyle habits of female nurses over a 26-year period, they discovered a positive correlation between a reduced risk for gout and long-term consumption of coffee. This applied to both caffeinated and decaffeinated varieties.
The reduced risk depended on the amount of daily coffee consumption –less 57% for those who drank more than four cups; 22% for those who drank one to three cups; and 23% for one cup – all in comparison with women who were non-drinkers.
In a study published in the Arthritis & Rheumatism, the benefit was also observed in men. Men who drank 4-5 cups per day lowered their risk by 40% while those who drank 6 cups or more had a 60% reduced risk .
Coffee’s high levels of antioxidants decrease gout risk because it decreases insulin that, in turn, decreases the levels of uric acid in the body. Gout is usually caused by high concentrations of uric acid resulting in the inflammation of the joints, the characteristic symptom of the disease.
#5.Contribute to a Healthier Brain
The caffeine in coffee is considered as a psychoactive substance because it contributes to a more alert mind and energized body. In fact, it’s the most commonly used substance of its kind.
Nearly as soon as you drink coffee, your bloodstream absorbs its caffeine where it travels then to your brain where it does its magic . Caffeine blocks adenosine, an inhibitory neurotransmitter, resulting in the increase of dopamine and norepinephrine . Your brain then experiences increased neuron activity so you feel more alert and more able to concentrate on tasks.
Many studies have also suggested that coffee consumption can lead to increased brain function across several areas. These include improved memory, reaction times, and concentration, as well as overall cognitive function .
Coffee being a psychoactive drink, it’s a healthy drink that can boost your mental and emotional health.
#6.Improve Your Intelligence, Possibly
According to a CNN report , regular coffee consumption can allow your brain to be smarter – or at least, it allows your brain to work in a significantly more efficient way. Your intelligence level will then seem better, especially with your increased reaction times, cognitive function, and logical reasoning, as described above.
In a Time report , such observation was also reinforced. According to Michael Lemonick, caffeine improves on these aspects even when you’re on a sleep deprivation streak. These complex functions are usually associated with intelligence so the more you’re up to speed on them, the more intelligent you seem.
Coffee isn’t just a great pick-me-upper in the mornings. It can also be great for getting up to speed during the day so drink it during your breaks instead of soda and the like.
#7. Reduce the Risk of Parkinson’s and Alzheimer's Diseases
The data about the positive correlation between higher coffee consumption and lower risk of Parkinson’s disease is, indeed, very consistent. Scientists have yet to discover the reason why but the current consensus is caffeine.
Coffee has also been associated with decreased risk of Alzheimer’s disease and dementia. In a 2009 study conducted over a 20-year period in Sweden and Finland involving 1,400 people, people who drank 3-5 cups daily had a reduced risk of 65% to develop these diseases, in comparison with occasional drinkers and non-drinkers.
In a study conducted by researchers from the University of Miami and University of South Florida , people older than 65 years who drank higher amounts of coffee developed Alzheimer’s disease later than occasional drinkers and non-drinkers. The delay in onset ranged from two to four years.
Moderate coffee consumption may delay the onset of Alzheimer’s in people with high risk for it, as well as appreciably reduce the risk for others. The emphasis here is on moderate consumption since excessive consumption of coffee has its side effects.
#8.Protect Your Liver from Diseases
In a study involving 125,000 people over a 22-year period , the individuals who drank at least a cup of coffee a day were 20% less likely to have liver cirrhosis. The excessive alcohol consumption-related autoimmune disease can lead to liver cirrhosis or liver cancer.
Coffee appears to provide some protection against the onset of liver cirrhosis. The researchers also noted that the higher the coffee consumed, the lower the risk of being hospitalized or dying due to the autoimmune disease.
If you have high risk for liver diseases, such as non-alcoholic fatty liver disease, you may want to drink four or more cups of java a day to prevent its progression . Your liver may be healthier for it even when it isn’t diseased or damaged, not to mention the other benefits mentioned here.
#9. Stabilize Mood and Emotions
If you enjoy comfort from drinking coffee, then you have something going on there! In a study conducted by the National Institute of Health , the researchers found that people who drink four or more cups daily were 10% less likely to experience depression in comparison with non-drinkers.
Coffee’s high levels of antioxidants  are probably the reason for it. No, it isn’t the caffeine since it’s also present in soda drinks like Coke yet these have been linked to depressive tendencies  instead.
Coffee consumption may even decrease the risk of suicide .
In a Harvard School of Public Health study, drinking 2-4 cups of coffee daily reduced the risk of suicide by about 50% in both men and women. The researchers suggested that coffee has a mild antidepressant effect because it stimulates the production of noradrenaline, dopamine, and serotonin, among other neurotransmitters.
While coffee shouldn’t be a substitute for antidepressants and psychotherapy in depressed individuals, it may help in elevating their mood and stabilizing their emotions. If you’re feeling down, the soothing feeling of drinking hot coffee may also have the same effect.
#10.Boost Physical Performance
Athletes have used caffeine in boosting their physical capacity, especially as a way to boost their athletic performance without resorting to banned substances . This is particularly true in endurance sports where cardiovascular stamina is a must, such as cycling and running.
Caffeine increases the quantity of healthy fatty acids in the bloodstream. In turn, the muscles can absorb them before burning these fatty acids for fuel purposes . The carbohydrate reserves can then be saved for later use, which means an athlete will have more fuel to tap into.
Think about increasing your coffee consumption but keep to moderate levels as part of your training diet. You may also drink a cup of coffee 30 minutes before your workout.
#11. Manage Everyday Pains
During a typical working day, many people can experience mild to moderate pain, a common occurrence. But many of them will also feel rejuvenated after drinking coffee .
In a Norwegian study, the participants who drank coffee only reported a 41 pain intensity level. The participants who didn’t reported a 55.
Caffeine, coffee’s active ingredient, seemed to reduce the sensitivity to pain . Scientists even say that it could even be more effective than medication, even in comparison with morphine.
The compound may also work because it boosts dopamine levels. Dopamine is a feel-good chemical.
Instead of reaching for your pain medications, you may want to drink a cup of coffee first and see what happens.
#12.Promote Effective Weight Loss
Caffeine is actually an ingredient in many weight loss supplements! Such inclusion isn’t surprising as studies have shown that it can boost metabolic rate by as much as 11% .
But emphasis must be made that caffeine in itself isn’t the be-all and end-all of effective weight loss. The combination of a healthy diet, appropriate exercise program, and sensible lifestyle habits is still the key to success. As people get amazing weight loss results by adding coffee to their diet.
Add cups of coffee or green coffee extract supplements to your weight loss program to improve your results.
#13. Enjoy Essential Nutrients
And if these health benefits aren’t enough, then you can look to the fact that coffee contains several essential nutrients for a healthy mind and body.
A single cup of regular coffee contains a wide range of nutrients  including Vitamin B, Vitamin B5, Vitamin B3, potassium, manganese, potassium, and magnesium
Coffee also has high levels of antioxidants  that slow down the signs of aging and lessens oxidative stress caused by free radicals. In the Western world, coffee may well be the main source of these beneficial compounds in people’s diet, especially as the emphasis is less on fruits and vegetables and more on meats.
Coffee is among the healthiest drinks aside from water and tea. Drink it within moderation and reap its health benefits.
Just as with all the good things in life, coffee must be consumed in moderation, usually 4-5 cups a day for adults. You may enjoy a longer and happier life for it, too.
