Coffee Benefits Essay Example for Free

Coffee Benefits Essay Several studies comparing moderate coffee drinkers (about 2 cups a day) with light coffee drinkers (less than one cup a day) found that those who drank more coffee were significantly less likely to develop Alzheimers disease later in life. [2][3] [edit] Reduced risk of gallstone disease Drinking caffeinated coffee has been correlated with a lower incidence of gallstones and gallbladder disease in both men[4] and women[5] in two studies performed by the Harvard School of Public Health. A lessened risk was not seen in those who drank decaffeinated coffee. [edit] Reduced risk of Parkinsons disease A study comparing heavy coffee drinkers (3. 5 cups a day) with non-drinkers found that the coffee drinkers were significantly less likely to contract Parkinsons Disease later in life. [6]. Likewise, a second study found an inverse relationship between the amount of coffee regularly drunk and the likelihood of developing Parkinsons Disease. [7] [edit] Cognitive performance Many people drink coffee for its ability to increase short term recall and increase IQ[8]. Likewise, in tests of simple reaction time, choice reaction time, incidental verbal memory, and visuospatial reasoning, participants who regularly drank coffee were found to perform better on all tests, with a positive relationship between test scores and the amount of coffee regularly drunk. Elderly participants were found to have the largest effect associated with regular coffee drinking. [9] Another study found that women over the age of 80 performed significantly better on cognitive tests if they had regularly drunk coffee over their lifetimes. [10] [edit] Analgesic enhancement Coffee contains caffeine, which increases the effectiveness of pain killers, especially migraine and headache medications. [11] For this reason, many over-the-counter headache drugs include caffeine in their formula. [edit] Antidiabetic Coffee intake may reduce ones risk of diabetes mellitus type 2 by up to half. While this was originally noticed in patients who consumed high amounts (7 cups a day), the relationship was later shown to be linear. [12] [edit] Liver disease Coffee can also reduce the incidence of cirrhosis of the liver[13] and has been linked to a reduced risk of hepatocellular carcinoma, a primary liver cancer that usually arises in patients with preexisting cirrhosis. [14] The exact mechanism and the amount of coffee needed to achieve a beneficial effect are as yet unclear. [15] [edit] Cancer Coffee consumption is also correlated to a reduced risk of oral, esophageal, and pharyngeal cancer. [16][17] In ovarian cancer, no benefit was found. [18] In the Nurses Health Study, a modest reduction in breast cancer was observed in postmenopausal women only, which was not confirmed in decaffeinated coffee. [19] [edit] Cardioprotective Coffee reduces the incidence of heart disease, though whether this is simply because it rids the blood of excess lipids or because of its stimulant effect is unknown. [citation needed] [edit] Laxative/diuretic Coffee is also a powerful stimulant for peristalsis and is sometimes considered to prevent constipation; it is also a diuretic. However, coffee can also cause loose bowel movements. Practitioners in alternative medicine often recommend coffee enemas for cleansing of the colon due to its stimulus of peristalsis, although mainstream medicine has not proved any benefits of the practice. [edit] Antioxidant Coffee contains the anticancer compound methylpyridinium. This compound is not present in significant amounts in other food materials. Methylpyridinium is not present in raw coffee beans but is formed during the roasting process from trigonelline, which is common in raw coffee beans. It is present in both caffeinated and decaffeinated coffee, and even in instant coffee. [20] http://ezinearticles. com/? Coffee-and-Its-Antioxidants-Healthier-Than-You-May-Realizeid=1235899 Did you know that coffee is chock full of antioxidants, an anticancer agent? If youve always thought coffee is bad for you, think again. Aside from keeping you alert and awake, coffee can also keep you young and fighting cancer. So, continue reading for answers to some frequently asked questions about coffee and its antioxidants. What are antioxidants? Antioxidants are any vitamin or nutrient that can help prevent cancer or damage to the heart and other tissues caused by free radicals. By neutralizing free radicals, they prevent cell degradation. Antioxidant rich foods include blueberries, raspberries, dates, chocolate and, of course, coffee. What type of antioxidants are in coffee? The antioxidants found in coffee are called polyphenols. More specifically, the compound is methylpridinium. The antioxidant isnt present in raw, green coffee beans, but is actually created during the roasting process. How much coffee is enough? Research has shown that people who drink one to two coffees a day have half the risk of developing liver cancer when compared to people who didnt drink coffee. Meanwhile, drinking 4 to 6 cups of coffee can reduce your risk for type-2 diabetes by as much as 50 percent. However, despite the reduced risk for these diseases and other cancers, like oral, esophageal, and pharyngeal cancer, doctors dont recommend you start drinking 10 cups a day. Coffee is still a stimulant and a diuretic and if drunk in excess can cause heart problems, anxiety and possible dangerously elevated blood pressure. Can I get these antioxidants from other sources? The specific antioxidant compound of methylpridinium is only found in substantial amounts in coffee. While other food sources like cranberries, dates and other antioxidant-rich foods contain different types of antioxidants, coffee is the primary source for this particular compound. (For other sources of antioxidants try bananas, dry beans, blueberries, pomegranates, lychees and the other foods listed above.) A recent study also found that the vast majority of North Americans get most of their antioxidants from beverages and, in particular, coffee. The average adult takes in about 1300 milligrams per day through coffee and the next source is tea at a mere 294 milligrams per day. Again, while coffee is one of our highest sources of antioxidants a great cancer-fighting and prevention agent coffee drinkers should always practice moderation. A cup or two a day may keep a number of common diseases away, but too much coffee can also cause problems. So balance is always a necessity.
