Coffee (Coffea L.) is one of the most regularly consumed beverages. Billions of cups of coffee are enjoyed every day by consumers around the world. The consumption of coffee is common among both younger and older adults, and at all times of the day. It uses at home, at work, and in cafes, bars, and restaurants. People use coffee knowing or without knowing the health benefit of the coffee beverage.
However, coffee has played an important role in human society. In fact, coffee is a complex mixture of caffeine, chologenic acid, phenolic compounds, and thousands of chemicals. Those chemicals are carbohydrate, lipids, vitamins, minerals, nitrogenous compounds, nicotinic acid, alkaloids, potassium, and magnesium.
Caffeine is the main partner and main bioactive compound for the health benefits of coffee. It is an alkaloid compound that naturally occurs in coffee beans. Also, caffeine is the most used psychoactive drug worldwide. In addition to that, caffeine induces the stimulatory effect in the central nerve system, increases metabolic rate, and associated with long-term memory and a positive effect on the brain.
Generally, people think of coffee as a potent enhancer. The stimulating effect of caffeine may remain, 15 min up to 6 hours after consumption. But researchers found many of the health benefits of coffee such as lower the risk of Type II diabetes, Liver cancer, reduce the risk of metabolic syndrome, and reduce the risk of death from heart failure, etc.
1. Minimize the risk of Type II diabetes
Type II diabetes is one of the biggest health issues in the current world and affects 300 million people worldwide. It is characterized by an increase in blood sugar in the situation of insulin resistance and an inability to secrete insulin.
Researchers suggest there is an association between coffee drinking and reduce the risk of type II diabetes. Also, several observational studies found daily coffee drinkers have a lower risk of developing diabetes.
Scientists believe coffee can avoid type II diabetes in several ways. Coffee helps to use body insulin and protect the insulin-produce cell, regulate blood sugar effectively, avoid tissue damage, and fight with a known risk factor of type II diabetes.
2. Lower the risk of liver cancer
The liver is one of the most important organs in the human body which can maintain thousands of body functions.
Cancer is a leading death cause in the world. The uncontrolled cells in the body may lead to cancers. Among the cancers, Liver cancer is the third most common form of cancer in the world.
In people with chronic liver disease, hepatocellular cancer in the liver is transformed into cancer cells, so that they develop into liver cancer. So coffee can reduce the risk of developing cancer cells.
Furthermore, caffeine can inhibit the proliferation of the liver cancer cell. Studies show that one cup of coffee reduces the risk of cancer by 20%. So coffee drinkers have a lower risk of liver cancer.
3. Maintain the liver health
The liver is an amazing organ that carries many important functions in the body. Fatty liver disease and hepatitis, as well as bad habits such as alcoholism, can cause liver disease. Cirrhosis occurs after further development of these conditions.
Research shows that regular coffee consumption can help prevent liver cirrhosis. Under cirrhosis condition, the body has high levels of liver enzymes. This condition is harmful to the body. Drinking coffee mitigates this risk.
4. Coffee reduces the risk of heart diseases
Most of the studies show caffeine, raises the blood pressure slightly and it can decrease over time. A heart attack is a dangerous condition caused by a blockage in the blood vessel. Coffee helps control this to some extent.
Furthermore, coffee can reduce the risk of strokes. There is enough evidence are available that coffee helps to protect from the arterial damage caused by inflammation.
But what’s important is that excessive consumption of coffee has the opposite effect. This means drinking one or two cups per day does not harm but drinking four or five cups per day could harm the body.
5. Coffee could help to reduce weight
Almost every commercial fat-burning supplement contain caffeine. It is one of the natural substances that use for fat burning. Caffeine can increase fat burning as well as boost metabolism.
Scientists have proven that caffeine can burn fat up to 10% of fat in obese people and 29% of fat in lean people. By the way, this will have people less impact on people who drink coffee regular basis.
Improving body performance is a great health benefit of coffee. The major partner in these tasks is caffeine.
It can stimulate the central nervous system and sent the signal to the fat cell to burn the body fat. Once the body breaks down the fat, they release it into the blood as free fatty acid and eventually burn it.
6. Coffee protects you from Alzheimer’s disease and Dementia
Alzheimer’s disease is the most common neurodegenerative disease in the world. This disease is the most common cause of Dementia.
Dementia is an overall term use to degrade memory, problem-solving, and other thinking skills that affect everyday activities. Usually, dementia affects people over 65, a condition that has not yet been treated.
However, there are a few things that can do to prevent these causes in the very first stage. Of all these, drinking coffee is the best thing to do.
Several studies have shown that caffeine can produce a brain enzyme that can protect against Dementia. Researchers believe daily coffee consumption can reduce dementia by 65%.
7. Reduce the risk of Parkinson’s disease
Parkinson’s disease is the second most common neurodegenerative disease in the world right after Alzheimer’s disease. A disease caused by the death of neurons that generate dopamine in the brain.
This condition develops slowly throughout the year and characterizes by trauma/shaking, slow movement, rigid muscles, loss of automatic movement, speech change, and difficulty writing.
Like Alzheimer’s, there is no cure. So, it is important to focus on prevention. Many research studies show coffee drinkers have a significantly lower risk of disease. Therefore, coffee drinkers have a 60% lower risk of developing Parkinson’s disease.
8. Reduce suicide risk and depression
According to the world health organization, depression is a common serious mental illness that causes disability worldwide. Depression can affect a person’s behavior, feelings, thoughts, and sense of well-being.
This disease can be identified among adults, Youngers, and children. The most dangerous form of depression is that, if not treated properly, the result is suicide.
If drinking a cup of coffee or two per day will make you feel good mentality. The caffeine contains in coffee which activates mode regulating neurotransmitters. So coffee drinking protects mental health, brightens the mood, and helps to fight against depression and leads to minimizing the risk of suicide by 50%.
Several research studies have shown that there is an inverse relationship between coffee consumption and depression. Which means regular coffee drinkers have a significantly lower risk of depression. This is one of the very best health benefits of coffee so far.
9. Coffee can improve the energy level of the body
Coffee can boost the energy level of your body and make you feel less tired. Caffeine is the most commonly used psychoactive agent in the world.
Caffeine works in the brain and blocks an inhibitory neurotransmitter. It has a stimulant effect, which in turn enhances the body energy level, general mental function, mood, as well as various aspects of brain function.
10. Coffee boost memory and improve concentrate
One of the psychological health benefits of the coffee beverage is its ability to boost short term memory and improve concentration. Researchers have discovered that caffeine has the potential to improve brain function and boost memory.
As always, the effect of caffeine stimulates specific areas of the brain that are responsible for memory and concentration. But there is insufficient evidence to prove how long the effect lasts or how it differs from person to person.
