除去暖身子外加提神，咖啡可还有不少好处哦。近期几年，科学家们研究了咖啡对于健康每个方面的影响，结论或许会叫你大吃一惊哦。
Heres why coffee may actually be one of the healthiest beverages on the planet.
下面就是为什么咖啡是地球上最健康的饮料之一是什么原因。
1. Coffee Can Make You Smarter
咖啡能叫你更聪明
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.
不只提神，还能叫你更聪明。咖啡里面的开心成分是咖啡因，这是最容易见到的开心剂。不少实验表明咖啡因对大脑的有着积极有哪些用途，能改变心情，降低反应时间，提高记忆力，提升警觉与认知功能。
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.
概要：咖啡因能阻隔大脑中的神经元，达到刺激成效。实验表明咖啡因对情绪和大脑运作都有好处。
2. Coffee Can Help You Burn Fat and Improves Physical Performance
咖啡能燃烧脂肪提升身体活动能力
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.
让我来讲说为何咖啡因是脂肪燃烧成分中最经济的方法吧。咖啡因，对中枢神经系统有着肯定的刺激成效，会提升新陈代谢和脂肪酸的氧化。咖啡还能提高运动的几个机制，包含从脂肪组织中活化脂肪酸。两次单独的汇集剖析中显示咖啡因能总体提升11%-12%的体能表现。
Bottom Line: Caffeine raises the metabolic rate and helps to mobilize fatty acids from the fat tissues. It can also enhance physical performance.
概要：咖啡因提升新陈代谢的速度，从脂肪组织中活化脂肪酸。还能提升体能活动表现。
3. Coffee May Drastically Lower Your Risk of Type II Diabetes
咖啡能减少患二类糖尿病的风险
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.
在察看研究中发现，咖啡能有效（23%-67%）减少患糖尿病的风险。在对45万7922位调查者的18项研究显示，天天一杯咖啡能减少7%的患病率。大家喝的咖啡越多，风险就越小。
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.
概要：喝咖啡能减少换二类糖尿病的风险。天天喝几杯咖啡的人更困难得糖尿病。
4. Coffee May Lower Your Risk of Alzheimers and Parkinsons
咖啡能减少患老年痴呆症和帕金森症的风险
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%.
不只能叫你短期内变得愈加聪明，还能在年老时保护你的大脑。阿尔茨海默病是世界上最容易见到的神经系统退行成人两性疾病，也是痴呆的重要原因。在调查研究中发现，咖啡饮用者能减少60%的患阿尔茨海默病风险。帕金森则是世界上第二大神经系统退行成人两性疾病，特点常表现为脑内神经死亡。咖啡能减少换帕金森病32%-60%的风险。
Bottom Line: Coffee is associated with a much lower risk of dementia and the neurodegenerative disorders Alzheimers and Parkinsons.
概要：咖啡能大大减少患神经系统退行疾病阿尔茨海默病和帕金森病的风险。
5. Coffee May be Extremely Good For Your Liver
咖啡对肝脏极有好处
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%.
肝脏是人体中非常重要的器官，承担着成百上千种要紧的机体功能。现代生活下，如过度饮酒和吃糖都会对肝脏导致肯定的损害。肝硬化是肝损伤的最后阶段，由酗酒或肝炎引起，到最后肝组织基本上被瘢痕代替。不少研究发现咖啡能减少80% 肝硬化的风险，尤其是对那些天天喝多于4杯咖啡的人。而咖啡还可以降低40%患肝癌的风险。
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%.
概要：咖啡能对肝组织紊乱有肯定的抵抗用途，降低40%患肝癌的风险，与80%患肝硬化的风险。
6. Coffee May Decrease Your Risk of Dying
咖啡能减少死亡率
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.
不少人还是感觉咖啡不健康。这也不奇怪，真理刚被提出时，总会被怀疑是谬论。在两大前瞻性时尚病研究中，喝咖啡能减少各种缘由的死亡率。对二类糖尿病中的成效也极其明显，研究表明20年来咖啡饮用者减少了30%的死亡率。
Bottom Line: Coffee consumption has been associated with a lower risk of death in prospective epidemiological studies, especially in type II diabetics.
概要：在前瞻性时尚病研究中发现，咖啡能减少死亡率，特别是二类糖尿病。
7. Coffee is Loaded With Nutrients and Antioxidants
咖啡富含营养和抗氧化剂
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.
咖啡不止是黑色的水。咖啡豆里富含很多的营养元素，如维他命和矿物质，到最后都能被大家饮下。
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.
还没有说完，咖啡还富含抗氧化剂。事实上，咖啡是西方食物中含抗氧化剂最多的，超越蔬菜和水果的总和哦。
Bottom Line: Coffee contains a decent amount of several vitamins and minerals. It is also the biggest source of antioxidants in the modern diet.
