Benefits of drinking coffee
喝咖啡的好处
1. Coffee has the effect of improving energy levels and making you smarter
咖啡可以提高你的能量水平，让你更聪明
Coffee can help people feel less tired and increase energy levels. That's because it contains a stimulant called caffeine - the most commonly consumed psycho-stimulant in the world.
咖啡可以帮助人们不那么疲劳，提高精力水平。这是因为它含有一种叫做咖啡因的兴奋剂——世界上最常见的精神兴奋剂。
After you drink coffee, the caffeine will be absorbed into your bloodstream. From there, it travels to the brain. In the brain, caffeine blocks the neurotransmitter that inhibits adenosine. When this happens, the amount of other neurotransmitters such as norepinephrine and dopamine increases, leading to an increased activation of nerve cells.
喝完咖啡后，咖啡因会被你的血液吸收。从那里，它传送到大脑。在大脑中，咖啡因会阻断抑制腺苷的神经递质。当这种情况发生时，其他神经递质如去甲肾上腺素和多巴胺的数量会增加，导致神经细胞的活化增加。
Numerous controlled studies in humans show that coffee improves various aspects of brain function - including memory, mood, alertness, energy levels, reaction times, and general mental function.
大量的人体对照研究表明，咖啡可以改善大脑功能的各个方面——包括记忆、情绪、警觉性、能量水平、反应时间和一般的精神功能。
2. Drinking coffee has a fat burning effect
喝咖啡有燃烧脂肪的作用
Caffeine is found in almost every fat-burning supplement. This is one of the few natural substances shown to help burn fat in the body.

Other studies have shown that caffeine in particular can increase fat burning by up to 10% in obese people and 29% in lean people.

However, it is possible that these effects will be lessened by long-term coffee drinkers.
然而，长期饮用咖啡的人可能会减少这些影响。
3. Drinking coffee has a powerful effect of improving physical performance
喝咖啡对提高身体表现有强大的作用
Caffeine stimulates your nervous system, signaling fat cells to break down fat in the body. But it also increases the levels of epinephrine in the blood.
咖啡因刺激你的神经系统，向脂肪细胞发出信号来分解体内的脂肪。但它也会增加血液中的肾上腺素水平。
This is a hormone that helps your body prepare for intense physical activity.
这是一种荷尔蒙，可以帮助你的身体为剧烈的体育活动做好准备。
Caffeine breaks down fat in the body, creating free fatty acids for fuel. Given these effects, it's not surprising that caffeine can improve physical performance by an average of 11-12%.
咖啡因能分解体内脂肪，产生游离脂肪酸作为燃料。考虑到这些影响，咖啡因能使身体表现平均提高11-12%就不足为奇了。
