1.紧张时添乱
咖啡因有助于提高警觉性、灵敏性、记忆力及集中力。但饮用超过比你平常所习惯饮用量的咖啡，就会产生类似食用相同剂量的兴奋剂，会造成神经过敏。对于倾向焦虑失调的人而言，咖啡因会导致手心冒汗、心悸、耳鸣这些症状更加恶化。
2.加剧高血压
咖啡因因为本身具有的止痛作用，常与其他简单的止痛剂合成复方，但是，长期大量服用，如果你本身已有高血压时，使用大量咖啡因只会使你的情况更为严重。因为光是咖啡因就能使血压上升，若再加上情绪紧张，就会产生危险性的相乘效果，因此，高血压的危险人群尤其应避免在工作压力大的时候喝含咖啡因的饮料。有些常年有喝咖啡习惯的人，以为他们对咖啡因的效果已经免疫，然而事实并非如此，一项研究显示，喝一杯咖啡后，血压升高的时间可长达12小时。
3.诱发骨质疏松
咖啡因本身具有很好的利尿效果，如果长期且大量喝咖啡，容易造成骨质流失，对骨量的保存会有不利的影响，对于妇女来说，可能会增加骨质疏松的威胁。但前提是，平时食物中本来就缺乏摄取足够的钙，或是不经常动的人，加上更年期后的女性，因缺少雌激素造成的钙质流失，以上这些情况再加上大量的咖啡因，才可能对骨造成威胁。如果能够按照合理的量来享受，你还是可以做到不因噎废食的。
另外，以下六种人不宜喝咖啡：
患高血压、冠心病、动脉硬化等疾病——长期或大量饮用咖啡，可引起心血管疾病。
老年妇女——咖啡会减少钙质、引起骨质疏松。妇女绝经后，每天需要加十倍的钙量。
胃病患者——喝咖啡过量可引起胃病恶化。
孕妇——饮过量咖啡，可导致胎儿畸形或流产。
维生素B1缺乏者——维生素B1可保持神经系统的平衡和稳定，而咖啡对其有破坏作用。
癌症患者———饮用过量的咖啡对正常人有致癌的危险。

Coffee isn't 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.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。
Here's why coffee may actually be one of the healthiest beverages on the planet.下面就是为啥咖啡是地球上最健康的饮料之一的原因。
1. Coffee Can Make You Smarter咖啡能让你更聪明Coffee doesn't 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。
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.
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. Coffee Can Help You Burn Fat and Improves Physical Performanc 咖啡能燃烧脂肪提高身体活动能力
There's a good reason why you will find caffeine in most commercial fat burning supplements. Caffeine, partly e 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。
Bottom Line: Caffeine raises the metabolic rate and helps to mobilize fatty acids from the fat tissues. It can also enhance physical performance.
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. Coffee May Drastically Lower Your Risk of Type II Diabetes咖啡能降低患二类糖尿病的风险
In observational studies, coffee has been repeatedly associated with a lower risk of diabetes. The rection 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。
Bottom Line: Drinking coffee is associated with a drastically reced risk of type II diabetes. People who drink several cups per day are the least likely to become diabetic.
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. Coffee May Lower Your Risk of Alzheimer's and Parkinson's咖啡能降低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. Alzheimer's 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 Alzheimer's and dementia. Parkinson's is the second most common neurodegenerative disorder, characterized by death of dopamine-generating neurons in the brain. Coffee may lower the risk of Parkinson's by 32-60%.
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性疾病，特征常表现为脑内神经死亡。咖啡能降低换帕金森病32%-60%的风险。
Bottom Line: Coffee is associated with a much lower risk of dementia and the neurodegenerative disorders Alzheimer's and Parkinson's.
总结：咖啡能大大降低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%.
肝脏是人体中最重要的器官，承担着成百上千种重要的机体功能。现代生活下，如过度饮酒和吃糖都会对肝脏造成一定的损害。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。很多研究发现咖啡能降低80% 肝硬化的风险，特别是对那些每天喝多于4杯咖啡的人。而咖啡还可以减少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%.
总结：咖啡能对肝组织紊乱有一定的抵抗作用，减少40%患肝癌的风险，以及80%患肝硬化的风险。
6. Coffee May Decrease Your Risk of Dying 咖啡能降低死亡率
Many people still seem to think that coffee is unhealthy. This isn't 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 ring a 20 year period.
很多人还是觉得咖啡不健康。这也不奇怪，真理刚被提出时，总会被怀疑是谬论。在两大前瞻性流行病研究中，喝咖啡能降低各种原因的死亡率。对二类糖尿病中的效果也极其明显，研究表明20年来咖啡饮用者降低了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.
总结：在前瞻性流行病研究中发现，咖啡能降低死亡率，尤其是二类糖尿病。
7. Coffee is Loaded With Nutrients and Antioxidants咖啡富含营养和抗氧化剂
Coffee isn't 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。咖啡豆里富含大量的营养元素，如维他命和矿物质，到最后都能被我们饮下。
But this isn't 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.
还没说完，咖啡还富含抗氧化剂。实际上，咖啡是西方食物中含抗氧化剂最多的，超过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.总结：咖啡富含维他命和矿物质，也是现代饮食中含抗氧化剂最多的饮品。

他们也是每天早上一被咖啡
没坏处的
早餐可以提高血糖浓度，振奋精神，为一天的工作做好准备。所以早餐的选择最好是一些消化较慢含糖分高的碳水化合物，这类食物会平稳地提升血糖浓度，维持你一上午的营养供给。例如，一小碗燕麦粥、一根半熟的香蕉、一杯原味酸奶或新鲜果汁都是很聪明的选择。但如果你实在无法抽时间准备早餐，就提前买好一盒饼干带到办公室去吧。
营养午餐
中午是吃丰富食物的时间。最好选择高蛋白的鱼肉、鸡肉、牛肉、鸡蛋或豆腐。这些食物内含的蛋白质可以帮助消化，也可以驱除餐后的睡意。记住中午不要吃太多主食，如面包、馒头、面条、米饭或土豆，这些食物只会让你一下午打不起精神，行动缓慢。
平衡晚餐
碳水化合物特有帮助睡眠的功效，所以用在晚餐最合适了。土豆、荞麦面的面条、大米等主食因为对脑细胞有舒缓作用，因此可以选择这些作为健康晚餐主食。临睡前喝一杯牛奶，可以放松紧绷了一天的神经，对你的睡眠也大有帮处。
