drinking coffee and health (喝咖啡的好处)

Drinking coffee daily would be good for your health Coffee isnt just warm and energizing, it may also be extremely good for you. In recent years, scientists have studied the effects of coffee on various aspects of health and their results have been nothing short of amazing. Heres why coffee may actually be one of the healthiest beverages on the planet. 1. Coffee Can Make You Smarter Coffee doesnt just keep you awake, it may literally make you smarter as well. The active ingredient in coffee is caffeine, which is a stimulant and the most commonly consumed psychoactive substance in the world. Many controlled trials have examined the effects of caffeine on the brain, demonstrating that caffeine can improve mood, reaction time, memory, vigilance and general cognitive function. Bottom Line: Caffeine potently blocks an inhibitory neurotransmitter in the brain, leading to a net stimulant effect. Controlled trials show that caffeine improves both mood and brain function. 2. Coffee Can Help You Burn Fat and Improves Physical Performance Theres a good reason why you will find caffeine in most commercial fat burning supplements. Caffeine, partly due to its stimulant effect on the central nervous system, both raises metabolism and increases the oxidation of fatty acids. Caffeine can also improve athletic performance by several mechanisms, including by mobilizing fatty acids from the fat tissues. In two separate meta-analyses, caffeine was found to increase exercise performance by 11-12% on average. Bottom Line: Caffeine raises the metabolic rate and helps to mobilize fatty acids from the fat tissues. It can also enhance physical performance. 3. Coffee May Drastically Lower Your Risk of Type II Diabetes In observational studies, coffee has been repeatedly associated with a lower risk of diabetes. The reduction in risk ranges from 23% all the way up to 67%. A massive review article looked at 18 studies with a total of 457,922 participants. Each additional cup of coffee per day lowered the risk of diabetes by 7%. The more coffee people drank, the lower their risk. Bottom Line: Drinking coffee is associated with a drastically reduced risk of type II diabetes. People who drink several cups per day are the least likely to become diabetic. 4. Coffee May Lower Your Risk of Alzheimers and Parkinsons Not only can coffee make you smarter in the short term, it may also protect your brain in old age. Alzheimers disease is the most common neurodegenerative disorder in the world and a leading cause of dementia. In prospective studies, coffee drinkers have up to a 60% lower risk of Alzheimers and dementia. Parkinsons is the second most common neurodegenerative disorder, characterized by death of dopamine-generating neurons in the brain. Coffee may lower the risk of Parkinsons by 32-60%. Bottom Line: Coffee is associated with a much lower risk of dementia and the neurodegenerative disorders Alzheimers and Parkinsons. 5. Coffee May be Extremely Good For Your Liver The liver is a remarkable organ that carries out hundreds of vital functions in the body. It is very vulnerable to modern insults such as excess consumption of alcohol and fructose. Cirrhosis is the end stage of liver damage caused by diseases like alcoholism and hepatitis, where liver tissue has been largely replaced by scar tissue. Multiple studies have shown that coffee can lower the risk of cirrhosis by as much as 80%, the strongest effect for those who drank 4 or more cups per day. Coffee may also lower the risk of liver cancer by around 40%. Bottom Line: Coffee appears to be protective against certain liver disorders, lowering the risk of liver cancer by 40% and cirrhosis by as much as 80%. 6. Coffee May Decrease Your Risk of Dying Many people still seem to think that coffee is unhealthy. This isnt surprising though, since it is very common for conventional wisdom to be at exact odds with what the actual studies say. In two very large prospective epidemiological studies, drinking coffee was associated with a lower risk of death by all causes. This effect is particularly profound in type II diabetics, one study showing that coffee drinkers had a 30% lower risk of death during a 20 year period. Bottom Line: Coffee consumption has been associated with a lower risk of death in prospective epidemiological studies, especially in type II diabetics. 7. Coffee is Loaded With Nutrients and Antioxidants Coffee isnt just black water. Many of the nutrients in the coffee beans do make it into the final drink, which actually contains a decent amount of vitamins and minerals. But this isnt all. Coffee also contains a massive amount of antioxidants. In fact, coffee is the biggest source of antioxidants in the western diet, outranking both fruits and vegetables combined. Bottom Line: Coffee contains a decent amount of several vitamins and minerals. It is also the biggest source of antioxidants in the modern diet. 喝咖啡的好处 除去暖身子外加提神，咖啡可还有不少好处哦。最近几年，科学家们研究了咖啡对 于健康各个方面的影响，结论可能会让你大吃一惊哦。下面就是为啥咖啡是地球上 最健康的饮料之一的原因。 1. 咖啡能让你更聪明 不仅提神，还能让你更聪明。咖啡里面的兴奋成分是咖啡因，这是最常见的兴奋剂。 很多实验表明咖啡因对大脑的有着积极的作用，能改善心情，减少反应时间，提升 记忆力，提高警觉以及认知功能。总结：咖啡因能阻隔大脑中的神经元，达到刺激 效果。实验表明咖啡因对情绪和大脑运作都有好处。 2. 咖啡能燃烧脂肪提高身体活动能力 让我来说说为什么咖啡因是脂肪燃烧成分中最经济的方式吧。咖啡因，对中枢神经 系统有着一定的刺激效果，会提高新陈代谢和脂肪酸的氧化。咖啡还能提升运动的 几个机制，包括从脂肪组织中活化脂肪酸。两次单独的荟萃分析中显示咖啡因能总 体提高 11%-12%的体能表现。总结：咖啡因提高新陈代谢的速度，从脂肪组织中活 化脂肪酸。还能提高体能活动表现。 3. 咖啡能降低患二类糖尿病的风险 在观察研究中发现，咖啡能有效（23%-67%）降低患糖尿病的风险。在对 45 万 7922 位调查者的 18 项研究显示，每天一杯咖啡能降低 7%的患病率。人们喝的咖啡 越多，风险就越小。总结：喝咖啡能降低换二类糖尿病的风险。每天喝几杯咖啡的 人更不容易得糖尿病。4. 咖啡能降低患老年痴呆症和帕金森症的风险 不仅能让你短期内变得更加聪明，还能在年老时保护你的大脑。阿尔茨海默病是世 界上最常见的神经系统退行性疾病，也是痴呆的主要原因。在调查研究中发现，咖 啡饮用者能降低 60%的患
