不少人愛喝咖啡，愛其香濃提神，但原來咖啡是個受爭議的飲品，美國赫芬頓郵報分別有兩位專家撰寫文章爭論到底咖啡對健康是好是壞。試看看兩方的觀點，看你會不會因此而戒掉喝咖啡的習慣。
認為喝咖啡有益：
- 咖啡因降低患上多種癌症的機會: "…coffee can lower your risk of several kinds of cancer, including prostate and skin cancer."
- 同時減低中風、患心臟病的風險: "…(regular comsupmtion of coffee can) decreased stroke risk among women who regularly consumed coffee and a recent study pointed to decreased risk of heart failure…"
- 增加多巴胺，紓緩壓力，使心情放鬆: "A good cup of coffee can lead to sensory delight……which increases dopamine in your brain (which has been correlated with happiness and health)."
- 延緩老人癡呆症的出現
指喝咖啡損害健康：
- 容易上癮，使人感覺更疲累: "It requires you to drink more and more...... Headaches, exhaustion and other biological signs of withdrawal put it clearly in the camp of addictive drugs."
- 難以進睡，增加患癌症及心臟病的風險: "Coffee has a lot to do this with the wide-ranging health impact of sleep deprivation on our health, including heart disease, obesity, Type 2 diabetes and cancer."
- 皮質醇和腎上腺素上升，令人情緒緊張: "It stimulates the release of stress hormones......This may lead to palpitations, anxiety, insomnia, and even spikes in blood sugar and insulin."
- 令牙齒變黃
看過正反兩方，你或許會感到困惑，為何兩邊的觀點那麼懸殊，正方說咖啡可預防疾病，而反方則指咖啡增加患病風險。到底那邊誰孰誰非至今未有肯定的答案，不過主場仔細比較過兩篇文章，發覺贊成咖啡對身體有好處的正方，其文引用多個研究及數字，相反反方文章少有引用學術研究，亦較多美國網民投票認同咖啡對身體有益。
不過可以肯定的是咖啡屬於刺激性飲品，攝取份量應適可而止，每天最多喝兩杯咖啡，亦可嘗試尋求醫生的專業意見。想身體健康應多做運動，保持均衡飲食。
