Benefits of Coffee

According to Harvard Women's Health, the consumption of several cups of coffee a day may reduce the risk of type 2 diabetes, the formation of kidney stones, colon cancer, Parkinson's disease, liver damage (cirrhosis), heart disease and prevent cognitive decline in brain power.

Diabetes.
Twenty studies conducted around the world shows that coffee reduces the risk of type 2 diabetes by 50%. The researchers speculate that the cause is chlorogenic acid in coffee play a role in digestion slows sugar absorption. Chlorogenic acid also stimulates the formation of GLP-1, the chemical that increases insulin (the hormone that regulates the absorption of sugar into the cells.) Other substances in coffee that trigonelin (pro-vitamin B3) is also thought to help slow the absorption of glucose.

Cancer.
Research consistently shows that coffee reduces the risk of liver cancer, breast cancer and colon cancer.

Cirrhosis.
Coffee protects the liver from cirrhosis, particularly cirrhosis due to alcoholism.

Parkinson's disease.
The coffee drinkers have half the risk of Parkinson's are lower than those who do not drink coffee.

Heart disease and stroke.
Coffee consumption does not increase the risk of heart disease and stroke. Contrast, coffee is actually slightly reduce the risk of stokes. A study of more than 83,000 women over the age of 24 years showed those who drank two to three cups of coffee a day had a risk of stroke by 19% lower than those who do not drink coffee. Studies from a number of men in Finland showed similar results.

Cognitive function.
A study of 4197 women and 2820 men in France showed that drinking at least three cups of coffee a day can prevent decline in cognitive function due to aging of the brain up to 33 percent in women. However, the same benefits not found in men. This may be because women are more sensitive to caffeine.

Negative effects of coffee
However, coffee also has a negative effect. Caffeine as main content of coffee is an addictive stimulant. Caffeine affects cardiovascular system such as increased heart rate and blood pressure. The negative impact that occurs when you consume to excess.

For most people, drinking two to three cups of coffee does not give a negative impact. Drinking coffee with more frequency than that can cause heart palpitations, insomnia, headaches and other disorders. Therefore, for those who consumed coffee that was not sleepy, for example because of lack of sleep, it is suggested that the consumption is spread throughout the day.

Research on the relationship of coffee consumption with miscarriage does not provide a uniform conclusion. But, for the safety of pregnant women are advised not to drink more than one cup of coffee a day.
