Coffee is one of the most loved and consumed beverages in the world. Besides offering a delicious aroma and rich flavor, coffee is also known for its multiple health benefits. In this article, we'll explore the scientific research and statistics proving the benefits behind every sip of this beloved beverage.
The main health benefits of a cup of Espresso are:
1) Cardiovascular protection
Contrary to what was thought in the past, recent studies have shown that moderate coffee consumption can have beneficial effects on the cardiovascular system. A study published by the National Institutes of Health concluded that moderate coffee consumption could reduce the risk of heart failure, stroke and coronary heart disease. This was also confirmed by a meta-analysis of 36 studies published in the Journal of the American Heart Association. The association between coffee and decreased risk of heart disease could be attributed to the antioxidants found in the drink.
2) Increased energy and improved physical performance
Coffee is known for its ability to boost energy levels and improve physical performance. The caffeine present in coffee stimulates the central nervous system, increasing alertness, concentration and physical endurance. A study conducted by the Harvard School of Medicine has shown that drinking coffee can improve performance in high-intensity exercise and can help burning fat during physical activity.
3) Positive effects on mental health and cognitive functions
Several studies have highlighted the benefits of coffee for the brain and mental health. Indeed, the caffeine contained in coffee is a well-known stimulant of the central nervous system: it stimulates the production of dopamine, noradrenaline and seratonin, neurotransmitters which influence mood, attention and memory.
According to a study published in the journal Archives of Internal Medicine, coffee consumption was associated with a reduced risk of suicide in both men and women.
Other research suggests that moderate coffee consumption may also be associated with a lower risk of depression and age-related cognitive decline.
4) Liver protection
Coffee has been associated with liver protection and the prevention of liver diseases, such as cirrhosis and liver cancer. A study published in the Journal of Hepatology found that coffee consumption can reduce the risk of cirrhosis of the liver by 44%. According to a study by the American Cancer Society, a regular coffee consumption could reduce the risk of liver cancer by up to 50%. Additionally, another study found that people who drink at least 4 cups of coffee a day have a significantly lower risk of developing liver cancer.
5) Reduction of the risk of some diseases
Coffee has been associated with a reduced risk of certain diseases, including type 2 diabetes and Parkinson's disease. A study conducted at Harvard University found that drinking coffee regularly can reduce the risk of developing Parkinson's disease by 30% - 60%.
6) Source rich of antioxidants
Coffee contains many antioxidants, such as chlorogenic acid, which help fight oxidative stress in the body, reducing the risk of chronic diseases. According to a study published in the Journal of Nutrition, coffee is the main source of antioxidants in the Western diet, surpassing fruits and vegetables. Regular antioxidant intake through coffee consumption is associated with a reduced risk of heart disease, type 2 diabetes and some cancers.
Coffee is more than just an energy drink, it offers a number of health benefits, backed by solid scientific evidence. From increasing energy and physical performance, to antioxidant action, improving cognitive functions and protecting the liver, the benefits of this drink are many.
