As drinking coffee can stimulate you body, coffee has also some brain boosting effects and other effects – Listed below are the health effects of coffee that have been scientifically proven.

Coffee stimulates and improves brain efficiency
Coffee helps to feel refreshed and raises energy levels. This is due to caffeine, which is the most widely used psychoactive substance in the world.

The caffeine in coffee blocks receptors in the brain that tiring adenosine is used to go to. At the same time, the production of other mediators, including dopamine, is also increasing. All this results in refreshment and elevated energy levels.

Many controlled experiments have shown that coffee affects the brain in other beneficial ways as well. Memory improves, alertness increases and reaction time decreases.

Coffee helps to lose weight and increases metabolism
Did you know that almost every commercial dietetic contains caffeine. Caffeine is one of the few natural substances that has a proven effect on fat burning.

Several studies show that caffeine increases metabolism by 3-11% . Another study found an effect of 10% in obese and up to 29% in lean people.

The effects may be slightly less when you drink coffee constantly.

Caffeine increases physical performance

Caffeine stimulates the nervous system and sends a command to fat cells to break down body fat. This gives the body more energy to use immediately. Coffee also increases adrenaline levels.

So it is no wonder that coffee increases physical performance by 11-12% on average. It is for this reason that before physical performance you should drink a big cup of good coffee. The benefits of coffee are familiar to many top athletes.

Coffee reduces the risk of type 2 diabetes

About 300 million people worldwide suffer from type 2 diabetes. The disease affects blood sugar levels and symptoms include fatigue, depression and irritability.

For some reason, coffee drinkers have a significantly lower risk of developing type 2 diabetes. Studies show that coffee drinkers have a 23-67% lower risk of developing the disease.

According to a large pooled study of 18 individual studies, covering a total of almost 500,000 people, each cup of coffee drunk per day reduced the risk of type 2 diabetes by 7%.

Drinking coffee protects you body and health in meny ways – Coffee protects against Alzheimer’s disease and dementia

Alzheimer’s disease is a degenerative brain disease that occurs in the elderly. Alzheimer’s disease is the most common disease that causes dementia. About 80 percent of all people with dementia have Alzheimer’s disease.

There is no cure for Alzheimer’s disease. However, certain things reduce the risk of developing Alzheimer’s. Common lifestyles such as a healthy diet have a big impact. Coffee also affects risk.

According to several studies, coffee drinkers have an up to 65% lower risk of developing Alzheimer’s disease.

Caffeine can reduce the risk of Parkinson’s disease
Parkinson’s disease is a slow-progressing movement disorder in middle and old age, accompanied by tremor, generalized movement and muscle stiffness, and numerous other symptoms.

What is Parkinson’s disease?

Parkinson’s disease (PD) is movement disorder of the nervous system that worsens over time. As nerve cells (neurons) in parts of the brain weaken or are damaged or die, people may begin to notice problems with movement, tremor, stiffness in the limbs or the trunk of the body, or impaired balance. As these symptoms become more obvious, people may have difficulty walking, talking, or completing other simple tasks. Not everyone with one or more of these symptoms has PD, as the symptoms appear in other diseases as well.

No cure for PD exists today, but research is ongoing and medications or surgery can often provide substantial improvement with motor symptoms.

What are the symptoms of the disease?

The four primary symptoms of PD are:

  • Tremor. Tremor (shaking) often begins in a hand, although sometimes a foot or the jaw is affected first. The tremor associated with PD has a characteristic rhythmic back-and-forth motion that may involve the thumb and forefinger and appear as a “pill rolling.” It is most obvious when the hand is at rest or when a person is under stress. This tremor usually disappears during sleep or improves with a purposeful, intended movement.
  • Rigidity. Rigidity (muscle stiffness), or a resistance to movement, affects most people with PD. The muscles remain constantly tense and contracted so that the person aches or feels stiff. The rigidity becomes obvious when another person tries to move the individual’s arm, which will move only in ratchet-like or short, jerky movements known as “cogwheel” rigidity.
  • Bradykinesia. This slowing down of spontaneous and automatic movement is particularly frustrating because it may make simple tasks difficult. The person cannot rapidly perform routine movements. Activities once performed quickly and easily—such as washing or dressing—may take much longer. There is often a decrease in facial expressions.
  • Postural instability. Impaired balance and changes in posture can increase the risk of falls.

Parkinson’s disease is caused by the death of dopamine-producing

neurons in the brain. Like Alzheimer’s disease, there is no cure for Parkinson’s disease, but treatment focuses on relieving symptoms.

Several studies show that coffee drinkers have a 32-60% lower risk of developing Parkinson’s disease than people who do not drink coffee.

In this case, the effect was due solely to caffeine, as caffeine-free coffee drinkers had a normal risk of Parkinson’s disease. Thus, the health effects of coffee are in part related to caffeine.

Coffee reduces the risk of liver cirrhosis

People who drink more than 4 cups of coffee a day have an 80% lower risk of developing cirrhosis.

Cirrhosis of the liver can develop with many different liver diseases. Liver well-being is really important for maintaining normal vital functions.

Coffee drinkers have a lower risk of developing cancer

Coffee drinkers has reduced the risk of developing liver cancer and colon cancer.

Studies show that the coffee drinker has 40% lower risk of developing liver cancer and a 15% lower risk of developing colon cancer.

In June 2016, the World Health Organization announced that coffee is not a source of carcinogens. For the past 25 years, the WHO had considered coffee a potential source of carcinogens in the absence of proper research. The change in listing was influenced by more than a thousand studies on the link between coffee and cancer.

Coffee can reduce the risk of heart attack

Coffee can raise blood pressure, but only to a small extent. If you drink coffee regularly, it no longer has an effect on blood pressure.

Coffee does not increase the risk of heart attack. Conversely, coffee may even reduce the risk of heart attack, at least in women.

Studies also show that coffee drinkers have a 20% lower risk of having a stroke.

Is drinking coffee regularly daily healthy? – Coffee really contains a lot of antioxidants

In the Western diet, coffee is actually one of the healthiest foods. The health effects of coffee are largely due to the antioxidants contained in coffee.
