烘焙好的咖啡中含有包括咖啡因、類黃酮、木聚糖和其他多酚類物質(zhì)在內(nèi)的數(shù)百種生物活性成分。研究表明這些成分以及咖啡中其他成分能增加能量消耗、抑制細(xì)胞損傷、調(diào)節(jié)參與DNA修復(fù)的基因并具有抗炎作用。

2. It could reduce your risk of suicide
2.降低自殺風(fēng)險(xiǎn)

It was found that the caffeine contained in coffee not only stimulates the central nervous system but may also act as a mild antidepressant by boosting production of some neurotransmitters in the brain like serotonin, dopamine, and noradrenaline.
研究發(fā)現(xiàn)咖啡中所含的咖啡因不僅能刺激中樞神經(jīng)系統(tǒng) ，可能還可以充當(dāng)輕度抗抑郁藥，促進(jìn)大腦中某些神經(jīng)遞質(zhì)的產(chǎn)生，如血清素、多巴胺和去甲腎上腺素。

3. It may reduce the risk of Alzheimer’s and dementia.
3.降低患老年癡呆和癡呆的風(fēng)險(xiǎn)

A recent study found that drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia and Alzheimer’s by about 65 percent later in life.
最近一項(xiàng)研究發(fā)現(xiàn)中年人每天喝3-5杯咖啡可以將晚年患癡呆和老年癡呆的風(fēng)險(xiǎn)降低約65%。

4. Reduces your risk of type 2 diabetes
4.降低患二型糖尿病的風(fēng)險(xiǎn)

What researchers found was that those who increased their coffee consumption by more than one cup per day had an 11 percent lower risk of developing type 2 diabetes.
研究人員發(fā)現(xiàn)每天多喝不只一杯咖啡的人患二型糖尿病的風(fēng)險(xiǎn)會(huì)降低11%。

Now, the bad news
現(xiàn)在說說壞處

1. You could get addicted
1.會(huì)上癮

Unless you drink decaf, coffee contains a high amount of caffeine. Caffeine is an addictive chemical that can create a dependency.

2. You could have more frequent urination
2.小便更頻繁

For years, people and even experts have named coffee as a diuretic. Continued studies have not linked the ingredients in coffee as contributing to frequent urination. So, if you drink a lot of coffee, expect a lot of that liquid to go to your bladder.
多年以來人們甚至專家都把咖啡當(dāng)成利尿藥物，但后續(xù)研究并不認(rèn)為咖啡中所含成分會(huì)導(dǎo)致尿頻。所以如果你喝了很多咖啡，那就會(huì)有大量液體進(jìn)入膀胱中。
