The science behind why coffee makes us happy
咖啡让我们快乐背后的科学依据
Coffee is a rich trove of many chemicals that play an important role in maintaining our overall health. A cup of coffee has:
• 2-Ethylphenol: A chemical that keeps us active and alert.
• 3,5 Dicaffeoylquinic acid: A component responsible for protecting us from neuron damage.
• Trigonelline: A form of vitamin B3 that fights with the cavity-causing bacteria in our mouth.
• Niacin: Vitamin B3, which is cell-rejuvenating and prevents dementia.
咖啡含有丰富的化学物质，对保持我们的整体健康起着重要作用。一杯咖啡中含有：
– 2-乙基苯酚：一种让我们保持活跃和警觉的化学物质。
– 3 , 5二咖啡酰奎宁酸：一种负责保护我们免受神经元损伤的成分。
– 葫芦巴碱：维生素B3的一种形式，可以对抗口腔中导致蛀牙的细菌。
– 烟酸：维生素B3，可以促进细胞再生，防止痴呆。
Adenosine is a neurochemical which makes us feel sleepy. When you drink coffee, caffeine enters your body, it works with the receptors that detect adenosine and blocks them from performing their regular function, and then prevents you from getting sleep. This is how you stay alert when you take coffee.
腺苷是一种使我们感到困倦的神经化学物质。当你喝咖啡时，咖啡因会进入你的身体，与检测腺苷的受体发生作用，并阻止它们发挥正常功能，阻止你入睡。这就是你在喝咖啡时能保持警觉清醒的原因。
