Coffee has become the subject of thousands of surveys in the past few years. Known as a simple stimulant it also has many other properties. Here are some of the most interesting statistics we could put together for proponents of coffee for healthier living.
At least 5% of surveys reveal that drinking coffee is associated with a decreased risk of mortality in men and women. For example, a long and large-scale survey, which studied more than 400,000 people, revealed that more coffee the men drink, the lower is their risk of mortality. By the survey results, men who drank 2 to 3 cups of coffee a day, showed a 10 percent lower risk of mortality and those people who had 4 to 5 cups a day showed even lower indicator, i.e. by 12%. Taking over 6 or more cups a day, decreased mortality by another 10 percent. As for women, the figures are a bit higher in women; they are affected by such parameters as age, body fat, race, education, and lifestyle factors.
2. Improves Cholesterol Balance
The coffee contains antioxidants which can balance the level of total cholesterol, increase “good” HDL cholesterol and lower heart disease-related inflammation. In one of the studies, coffee drinkers were asked to raise their coffee intake to 4 and then to 8 cups a day. This dose improved the ratio between “bad” LDL and HDL cholesterol by more than 8 percent.
3. Decreases Metabolic Syndrome
Metabolic syndrome is one of the most serious and very common health problems in the world; it can increase risks of heart failure and diabetes. Coffee drinking is good for fat burning and it potentially affects the body composition and lowers the diabetes risk.
4. Happy reproductive systems
Many studies have shown that regular drinking of coffee can lower the risk of prostate cancer in men and risk of endometrial cancer in women. In 2011, one of the surveys found that the men who consumed over 6 cups of coffee a day reduced the risk of prostate cancer by almost 20 percent. As for women, a study published in Journal Cancer Epidemiology, Biomarkers and Prevention showed that women who had more than 4 cups of coffee a day lowered risk of endometrial cancer by almost 25 percent.
5. Vascular Health
Several studies showed that caffeine in coffee can improve the health of the blood vessels as it increases nitric oxide production in the endothelium and the letter improves vascular muscle tone. Coffee also maintains healthy arterial pressure and lowers the blood pressure over the long-term. Even though drinking caffeinated coffee can increase short-term acute blood pressure, it will return to normal after the caffeine is metabolized.
6. Caffeine can make you stronger
Sports scientists tested caffeine supplements on athletic performance and found that if you get the right dose of pre-workout caffeine (as a supplement, because the necessary dose of caffeine intake would be 6 to 9 cups for a 90 kg athlete) your athletic performance will be much higher. The studies show that caffeine acts directly on the muscles and generates more power and strength.
7. Improves Body Composition & facilitates Fat Burning
There is much evidence that coffee can increase your metabolic rate and help you burn more calories, shifting the body to burn fat instead of glucose for energy. Besides, coffee can reduce blood sugar and improve insulin sensitivity.
In the recent past, the fat loss effect of coffee has not been studied extensively, but one study found that drinking 500 ml of coffee a day during one month produced 2.5 kg weight loss. The most effective is probably a green coffee extract, which comes from an unroasted coffee and may be added to any beverage. They say it can produce significant fat loss, e.g. one study revealed that a high-dose of green coffee extract will lead to minus 8 kg and 4.4 percent of body fat in only a month, very impressive, isn’t it?
8. Brain Gain
Some of the studies suggest that moderate coffee drinking (1 to 5 cups daily) may reduce the risk of dementia and Alzheimer’s disease, as well as Parkinson’s disease. The fact is that coffee contains antioxidants which may prevent some of the brain cells from damage. ¬Preliminary studies have reported that this lowers the ¬incidence of glioma – one of the forms of brain cancer.
9. Liver friendly
This issue has not been extensively studied, but one of the studies showed that heavy coffee drinkers had the lower incidence of cirrhosis and other liver diseases. Analysis of nine studies on the matter revealed that every 2-cup increase of daily consumption of coffee resulted in 43% lower risk of liver cancer. Possible reason being: the caffeine and antioxidants in coffee prevents liver inflammation and development of cancer cells.
一些研究表明，適度飲用咖啡（1到5杯每日）可能會降低癡呆和阿爾茨海默氏病的風險，以及帕金森氏病。事實是，咖啡中含有的抗氧化劑，可以防止一些從損壞的腦細胞。¬初步研究報告說，這降低膠質瘤的發病率¬ - 腦癌的形式之一。
