Theophylline in coffee broncioles expands in the lungs and helps to better aeriation three lung tissue. Coffee can be a diaphoretic (increases sweating) and diuretic (increases the frequency of urine) also do focus on drinking more water 4. Caffeine increases muscle tone in small dose before exercise and may prolong the duration of isotonic exercises (like running) EDIT: This will be an interesting news for you: the caffeine in coffee is the most addictive drug use common in U.S.! EDIT: I can further development on the chemical basis if you are interested. 5. The synergistic action for drugs used to relieve headache pain — ————————————- – EDIT: (Deputy Wikipedia) Benefits [edit] Reducing the risk of Alzheimer's disease, several studies comparing moderate drinkers (about 2 cups per day) with light coffee drinkers (less than one cup per day) found that who drank more coffee were significantly less likely to develop Alzheimer's disease in the future. 2] [3], [[Risk edit] Drinking coffee cholelithiasis with caffeine was associated with a lower incidence of gallstones and gallbladder in humans [4] and women [5] in two studies conducted by the School of Health Harvard Public. A reduction in risk was not observed those who drank decaffeinated coffee. [Edit] Reduced risk of Parkinson's Disease Study comparing coffee drinkers (3.5 cups per day) with non-drinkers found that coffee drinkers were significantly less likely to contract the disease Parkinson's in the future. [6]. Similarly, a second study found an inverse relationship between the amount of coffee regularly drunk and the likelihood of developing disease Parkinson's disease. [7] [edit] Cognitive performance Many people drink coffee for its ability to increase short-term recovery and increase IQ [8]. Similarly, in tests of simple reaction time, choice reaction time, verbal memory, accessories, and visual-spatial reasoning, participants who regular coffee drinkers had better results in all tests, with a positive relationship between test scores and the amount of regular coffee status drunkenness. Older participants found that the effect was most consistently associated with coffee consumption. [9] Another study found that women over 80 years performed significantly better on cognitive tests if they had regularly drunk coffee over their lives. [10] [edit] Analgesic coffee contains caffeine improves which increases the effectiveness of analgesics, especially migraine and headache medications. [11] For this reason, many OTC drug headaches are caffeine in its formula. [Edit] antidiabetic coffee intake may reduce the risk of type 2 diabetes mellitus, halfway. Although this was first noticed in patients have consumed large amounts (7 cups a day), the relationship was later shown to be linear. [12] [edit] Coffee liver can also reduce incidence of liver cirrhosis [13] and has been associated with a lower risk of HCC, primary liver cancer that usually arises in patients with cirrhosis existing [14]. The exact mechanism and the amount of coffee needed to achieve a beneficial effect remain unclear. [15] [edit] Cancer coffee consumption also correlates with a reduced risk of oral cancer, esophagus, pharynx, and cancer. [16] [17] In ovarian cancer, there were no benefits. [18] In the Nurses Health Study, a modest reduction in breast cancer was observed only in postmenopausal women, which has not been confirmed in decaffeinated coffee. [19] [Edit coffee] cardioprotective reduces the frequency of heart disease, but it is simply because they free the blood of excess fat or because of its stimulating effect is unknown. [Citation needed] [edit] Laxative / diuretic coffee is also a powerful stimulant for peristalsis and is sometimes considered to prevent constipation, is also a diuretic. However, coffee can also cause diarrhea. practitioners of alternative medicine often recommend coffee enemas to "clean the colon "due to recovery of peristalsis, but traditional medicine has not proven the benefits of practice. [Edit coffee] contains antioxidants anticancer compound methylpyridinium. This compound is not present in significant amounts in other food products. Methylpyridinium not present in coffee beans Green but is formed during the roasting process trigonelline, which is common in green coffee beans. It is present in both caffeinated and decaffeinated coffee, and even in instant coffee. [20] [edit] Prevention of dental caries tannins in coffee may reduce the cariogenic potential of foods. In vitro experiments demonstrated these polyphenolic compounds may interfere with Streptococcus mutans glucosyltransferase activity, which can reduce plaque formation. In experiments on rats, tea polyphenols reduced caries. [21] [edit] The fall in coffee consumption reduces the risk of gout in men over 40. In a large study of more than 45,000 older men 12 years, the risk of developing gout in men over age 40 was inversely proportional to the amount of coffee consumed. [22] [edit] Many risks significant effects of coffee are related to its caffeine content. Other associations known to be harmful to health, it is unclear whether the compounds are due to caffeine or other unidentified (suggesting that you can change if you switch to decaf.)

[24] [edit] cholesterol coffee brewed in a French press method contains oils (cafestol and kahweol) otherwise trapped through the filters of paper used. In two short-term studies, these oils are considered high levels of LDL cholesterol by 10 percent [25]. The risk is not present in the coffee filter paper. [Edit] The blood pressure of caffeine has been implicated in the increased risk of hypertension, but recent studies have not confirmed a association. In a 12-year study of 155,000 nurses, large amounts of coffee did not induce an increased "risk of pressure pressure. [26]. Previous studies had shown statistically significant associations between coffee consumption and hypertension clinic. Effect of coffee on morbidity and mortality due to its effect on blood pressure is too low and has not been studied. Another positive and negative effects of coffee on health would be confounding factors that are difficult.

"The results suggest a threshold effect around four to seven cups a day, "the study said. Those who drank at least eight glasses a day (64 U.S. fl oz or 1.89 L) were 220% compared to no higher risk drinkers. This study did not repeat, but has made some doctors caution against excessive coffee consumption during pregnancy [27]. It also has gender-specific effects: in some patients increases symptoms of PMS and may reduce fertility in women, may increase the risk of osteoporosis in postmenopausal women, and there may be risks to the fetus if a pregnant woman drinks 8 or more cups per day (64 U.S. fl oz or 1.4 L or more). Decaffeinated coffee is sometimes considered as a potential risk to the health of pregnant women, because of the high incidence of chemical solvents used to remove caffeine. These concerns have almost no basis, however, that the solvents evaporate at 80-90 ° C, and the coffee beans are decaffeinated before roasting, which occurs in 200 ° C. As such, these chemicals, namely, chloroform and methylene chloride, are present in small amounts at most, and is not a significant threat to the unborn.

This study concluded that coffee consumption is associated with significant elevations of biochemical markers of inflammation. It is a harmful effect of coffee in system cardiovascular, which may explain why coffee has so far been shown to help the heart of the levels of four cups (24 ounces or 600 ml) or less per day. [28] The health risks of decaffeinated coffee have been studied, with varying results. One variable is the type of decaffeination process used, while others involve the use of organic solvents which may leave residual traces, others based on steam. [Edit] One study has shown that cafestol, a substance that is present in beverages boiled coffee, increases the cholesterol levels, especially among women. filtered coffee contains only trace amounts of cafestol. CYP1A2 gene polymorphisms can lead to a slowing metabolism of caffeine.
