The health benefits of having at least one cup of coffee a day are becoming more and more numerous. Today we are reviewing the advantages of this drink that has been consumed in the population for several centuries and is also one of the most popular and most ingested throughout the world.
Coffee protects against type 2 diabetes
According to a study by a team of researchers at the University of California, Los Angeles (USA), drinking coffee increases plasma levels of sex hormone-binding globulin (SHBG), which controls the biological activity of the body’s sex hormones (testosterone and estrogen) and plays a key role in the development of type 2 diabetes. The work showed an inverse relationship between coffee consumption and the risk of developing type 2 diabetes. Thus, study participants who took more than one cup a day over a 4-year period had an 11% lower risk of type 2 diabetes compared to people who did not change their intake.
Coffee reduces the risk of liver cancer
A team of researchers from the Istituto di Ricerche Farmacologiche Mario Negri (Italy) carried out an experiment that showed that coffee is good for health and particularly for the liver. Thus, they discovered that coffee consumption reduces the risk of liver cancer by 40%. This result improved to over 50% if consumption increased to three cups of coffee per day.
Coffee Prevents Parkinson’s Disease
A study conducted at the McGill University Health Centre Research Institute (USA) and published in the journal Neurology showed that “higher coffee intake has been associated with a significantly lower occurrence of Parkinson’s disease” on top of that, the caffeine contained in coffee helps in controlling body movement in people who have this disease.
If we have already seen that coffee reduces the risk of liver cancer, another study by the Kaiser Permanente Medical Care Program in California (USA) concluded that regular coffee consumption is also linked to a lower risk of primary sclerosing cholangitis (PSC), a rare autoimmune disease of the bile ducts in the liver. In addition, it also reduces the incidence of cirrhosis (especially alcoholic cirrhosis) by a not inconsiderable 22%. The research was published in the journal Hepatology.
Coffee is good for the heart
A team of researchers from Beth Israel Deaconess Medical Center and the Harvard School of Public Health (USA) concluded that moderate coffee consumption (2 cups a day) protects against heart failure. In particular, the decrease in risk represented 11% compared to those who did not consume coffee.
Coffee reduces the risk of stroke
A Japanese study monitored the coffee consumption of 83,269 adults aged 45 to 74 years found that people who drank coffee daily had a 20% lower risk of stroke compared to those who did not drink coffee often.
Coffee protects vision
Can coffee protect our sight? This is evidenced by a recent study. Research published in the Journal of Agricultural and Food Chemistry concluded that coffee consumption can protect against vision impairment and even blindness.
Coffee protects against prostate cancer
Another of the benefits of coffee has to do with its protection against cancer, specifically prostate cancer. Thus, according to a study published in the journal Cancer Causes and Control, men who drank four or more cups of coffee a day had a 59% lower risk of recurrence in prostate cancer progression than those whose coffee consumption was as low as one cup a week or even less.
Coffee helps you lose weight
If you are looking for a healthy drink that also provides you with few calories, coffee can be a very good choice. A cup of coffee, without milk or cream and without sugar only contains about 2 calories. If we add sugar to it, the calories skyrocket but this can be solved by taking it without it or with natural sweeteners such as stevia.
Coffee protects against noises in the head or “tinnitus”.
The most common cause of tinnitus is exposure to noise, and according to a study published in The American Journal of Medicine, it is less common in women who consume more coffee because of the caffeine contained in this dark, tasty beverage.
Coffee reduces the risk of endometrial cancer
Endometrial cancer is the most common cancer of the female reproductive organs and affects about 1 in 37 women in their lifetime. Now, a new study has put it on the table that drinking three or four cups of coffee a day can reduce the risk of endometrial cancer by almost 20%.
Coffee is good for the arteries
A recent study concluded that drinking three to five cups of coffee a day reduces the risk of artery blockage and heart attacks.
Coffee is a source of natural antioxidants
The coffee bean contains about 1500 compounds, many of which are beneficial to health, such as antioxidants. In fact, coffee ranks 6th out of the top 50 foods containing antioxidants, according to The American Journal of Clinical Nutrition. Coffee has a high content of antioxidants such as polyphenols, bioactive compounds that prevent the functional and structural alterations of various diseases.
Coffee keeps us alert
Caffeine is the most important component of coffee and the most consumed psychoactive in the world – what causes caffeine? It acts in our brain as soon as we take it by blocking a neurotransmitter, adenosine, which causes the increase of other substances such as dopamine or norepinephrine, which only accelerate our brain activity. Thus, several studies have confirmed that coffee improves mood, energy levels, memory or our reaction times.
Drink coffee yes, but in moderation
We have already seen the benefits of coffee, but like everything else, you have to know how to drink it in moderation. Drinking too much coffee can cause some very unpleasant adverse effects. Thus, according to a study carried out by researchers at the University of Oklahoma (USA), “caffeine can cause anxiety symptoms in normal individuals, especially in vulnerable patients, such as people with pre-existing anxiety disorders. In addition, “caffeine consumption has also been associated with symptoms of depression.
