Millions around the world start their day with a cup of coffee for a boost of energy, but few realize that this everyday beverage also holds tremendous health benefits.
Coffee has gone beyond being just a stimulant to become the focus of many scientific studies that prove its role in preventing chronic diseases.
In this report, we review seven scientifically proven benefits of your daily coffee, according to the latest global research findings.
First: Protecting the brain from dementia and cognitive decline
A Harvard University study found that drinking three cups of coffee (or two cups of tea) a day reduces the risk of dementia by 18% and slows cognitive decline. Coffee consumption is also linked to a lower risk of Parkinson's disease and may help those with the disease improve motor control.
Other research has shown that espresso coffee may reduce the risk of developing Alzheimer's disease.
Moderate coffee consumption (1-2 cups daily) reduces the risk of heart failure and is associated with a lower risk of death from cardiovascular disease.
Studies have found that drinking 2-3 cups a day reduces the risk of heart disease, stroke, and type 2 diabetes.
Another study showed that average coffee consumers had a 21% lower chance of having a stroke and a 17% lower risk of death.
However, more than four cups a day may raise blood pressure and heart rate. Timing is also important—drinking it before lunch is better than drinking it throughout the day.
Third: Reducing the risk of developing type 2 diabetes
Coffee enhances the body's ability to process glucose, thus reducing the risk of developing diabetes. Research has found that coffee drinkers have a lower likelihood of developing this disease, and replacing sugary drinks with coffee or tea can extend the lifespan of people with diabetes.
Fourth: Protecting the liver and reducing the risk of cirrhosis and cancer.
Whether it's regular or decaffeinated coffee, it protects the liver. The study linked one to two cups a day to a 20% lower risk of cirrhosis and a 24% lower risk of liver cancer.
The greatest benefit is seen when drinking 3-4 cups daily. However, researchers do not recommend simply starting to drink coffee to protect the liver; they emphasize the importance of maintaining a healthy weight, limiting alcohol consumption, exercising regularly, and managing blood sugar, blood pressure, and cholesterol levels. A previous study also warned that adding sugar to coffee may harm the liver.
against liver cancer, but it is also linked to a reduced risk of colorectal, uterine, and head and neck cancers. A systematic review showed that high coffee consumption reduces the overall risk of cancer by 18%.
An Italian study estimated that drinking up to five cups of coffee a day reduces the risk of developing and dying from bowel cancer. However, drinking very hot coffee may increase the risk of esophageal cancer.
Coffee also seems to uplift the spirits; studies have linked drinking coffee to a 20% lower risk of depression, and consuming four or more cups a day is associated with a 53% lower risk of suicide.
With these accumulated benefits, it's no surprise that researchers have shown coffee drinkers live longer. A study that followed more than 400,000 people for 12-13 years found that drinking coffee was associated with a reduced risk of death, with the greatest benefit for those who drank 4-5 cups a day.
