Benefits of coffee:
1. Coffee helps fight depression
A study by the National Institutes of Health in the USA found that people who drink on average four cups of coffee a day are 10% less prone to depression than those who never drink coffee.
Since the effect in question could not be observed following the consumption of other caffeinated beverages (fizzy drinks, for instance), the positive mood is not generated by caffeine, but by the antioxidants in coffee beans.
2. Coffee reduces the predisposition toward suicide
A large-scale study by the Harvard School of Public Health has highlighted an impressive statistic that consumption of 2-4 cups of coffee per day reduces the predisposition to suicide for men and women by up to 50%.
On the other hand, a Finnish study highlights the effects of excess coffee on mental health.
The results of the research show that people who drink between 8 and 9 cups of coffee a day have a higher susceptibility to committing suicide, compared to the moderate drinkers.
3. Coffee helps regulate liver activity
Several specialized studies suggest that daily coffee consumption can help the liver to regulate its functions.
Researchers at the Mayo Clinic in the US have found that daily coffee intake can reduce the risk of developing primary sclerosing cholangitis, a rare autoimmune disease that causes liver cirrhosis, liver failure and even liver cancer.
Another research of 125,000 participants shows that alcoholics who drink a cup of coffee a day reduce their chances of developing alcoholic cirrhosis by 20%.
4. Coffee is a powerful stimulant of the brain
Coffee increases cerebral and physical performance substantially, being used by many athletes before entering competitions.
Caffeine increases the number of fatty acids circulating in the blood stream, thereby enhancing sports performance.
5. Coffee reduces the risk of developing type II diabetes
According to Science Daily, consumption of 3-4 cups of coffee per day may be associated with 25% fewer chances of developing type II diabetes. Researchers have not been able to formulate a concrete explanation of the phenomenon, although it has been observed that chlorogenic acid in coffee inhibits early glucose and insulin response.
6. Coffee reduces the risk of Parkinson’s and Alzheimer’s disease
There is sufficient scientific evidence to prove the efficiency of coffee in prevention of the installation of neurodegenerative diseases. A study has shown that coffee drinkers are 60% less likely to suffer from Alzheimer’s and dementia, and another research in the field suggests that this drink reduces the risk of developing Parkinson’s disease by 32 to 60%.
Neuroscientist Chuanhai Cao, a representative of the University of South Florida, motivates coffee efficiency by the fact that a sufficient dose of caffeine in the body inhibits the secretion of a protein called beta-amyloid that accumulates in the brain cells of Alzheimer’s sufferers. With aging, the protein becomes more difficult to metabolize. Excess beta-amyloid damages brain cells, so caffeine is useful in eliminating it.
