According Harvard Women's Health, 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 inhibit cognitive decline in brain power.
Diabetes. Twenty studies conducted worldwide indicate that
coffee reduces the risk of type 2 diabetes by 50%. The researchers guessed the
cause is chlorogenic acid coffee act to slow absorption of sugar in digestion.
Chlorogenic acid also stimulates formation GLP-1, a chemical that increases
insulin (a hormone that regulates the absorption of sugar into the cells).
Other substances in coffee that trigonelin (pro-vitamin B3) also thought to
help slow the absorption of glucose.
Heart disease and stroke. Coffee consumption does not increase
the risk of heart disease and stroke. Instead, coffee actually slightly reduces
the risk of stroke. A study of more than 83,000 women aged over 24 years showed
those who drank two to three cups of coffee a day had a stroke risk 19% lower
than those who did not drink coffee. Studies of a number of men in Finland
showed similar results.
Cancer. Research has consistently shown 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
developing Parkinson's disease is lower than those who did not drink coffee.
Cognitive function. The study of 4197 women and 2820 men in
France showed that drinking at least three cups of coffee a day can prevent
cognitive decline and brain aging by up to 33 percent in women. However, the
same benefit was not found in men. This may be because women are more sensitive
to caffeine.
Research the relationship of coffee consumption with
miscarriage does not give the same conclusion. But pregnant women should be
advised not to drink more than one cup of coffee a day.
For most people, drinking two to three cups of coffee no
negative impact. Drinking coffee with more frequency than that can cause heart
palpitations, insomnia, headache and other disorders. Therefore, for those who
consumed coffee that was not sleepy-such as lack of sleep-advised to spread
consumption throughout the day.
However, coffee also has a negative effect. Caffeine as the
main content of coffee is an addictive stimulant. Caffeine affects the
cardiovascular system such as increased heart rate and blood pressure. The
negative impact comes when you consume to excess.
