為什麼吃巧克力會打噴嚏？特別是黑巧克力？

謝邀。

我吃黑巧克力會High

可能是你的鼻炎影響到你吃巧克力了，兩個平行線因為你在乎所以香蕉了

總有人說吃巧克力會打噴嚏，但是他們並不對巧克力過敏。巧克力會讓人打噴嚏嗎？

答案是肯定的。巧克力致人噴嚏的原理和刺眼的陽光，薄荷，紅酒，或者別的亂七八糟的東西是一樣的。這個現象學名「光噴嚏反射」。（以光命名是因為這種噴嚏的最常見原因是強光）一種解釋是這種反射源於感光神經受到過度刺激，而且和三叉神經搭上了線，然後就產生了噴嚏。

但是吃巧克力的時候我又不用眼睛：噴嚏的原理是吸入外界顆粒或者刺激物。也許與基因遺傳有關，20-35%的人類有這個反射。National Center for Biotechnology Information還給它起了個更專業的名字叫Autosomal Dominant Compelling Helioopthalmic Syndrome。

好在打個噴嚏沒啥大不了的。口口相傳，越是黑巧克力（可可含量大於70%），越是刺激。下次吃的時候，備好擦鼻涕紙，然後你還可以給周圍的人科普一下。

Weve been hearing this one for years; there are those who swear up and down that chocolate makes some people sneeze, yet they are not allergic to chocolate. So what』s the scoop? Are these people imagining things, or can chocolate really make you sneeze?

Yes! Chocolate can make some people sneeze, in the same way that bright sunlight or mints or red wine or other apparently unrelated triggers do. There is a phenomenon called 「photic sneeze reflex」 (「photic」 is for bright lights, the most common cause of this type of sneezing). One theory about this reflex involves overstimulation of the optic nerve (which can occur when you look at bright sunlight) and that it somehow messes with the trigeminal nerve, which is responsible for sneeze production.

But that doesn』t explain why some people sneeze when they eat chocolate. Sneezing is a result of breathing in a foreign particle, some kind of irritant. The body rids itself of these irritants with a sneeze. Yet this type of sneezing is not associated with an allergy to chocolate. Clearly, this reflex is not well-understood. It is thought that the reflex is transmitted hereditarily, and it afflicts roughly 20 to 35 percent of the population. The National Center for Biotechnology Information refers to photic sneeze reflex by its technical name, Autosomal Dominant Compelling Helioopthalmic Syndrome (ACHOO for short—no kidding; look it up).

Luckily, the photic sneezing that results from eating chocolate is not serious. From anecdotal evidence we』ve seen, darker chocolate (70% and above) tends to induce sneezing in more people. What to do if you love chocolate but it makes you sneeze? Have a few tissues at hand and get ready for some puzzled looks when you explain ACHOO to others in the room, but know that you don』t need to stop consuming one of your favorite foods.

誒，我也是……吃黑巧克力和薄荷糖，都會打噴嚏

---

可能對可可過敏。

---

應該是對巧克力當中的某種成分過敏

---

為什麼出門會打噴嚏.特別是冬天的時候吶? ?????

---

過敏了。。

---

我吃70%的瑞士蓮黑巧克力必打噴嚏

---

我也是……簡直是巧克力中可可含量的指南針，拿來巧克力我吃一點，70%以上可可含量的話准打（注意是可可含量不是代可可脂，差別蠻大的），不過也就第一口管用，後面就不打噴嚏了。然後就是酒精，紅酒及濃度高一點的白酒喝一小口都打，啤酒一點事兒都沒有。其他的物質的話得慢慢補充了。

原因絕對不是過敏，這個我肯定。

另外我也看了英文文獻說什麼可能是「光噴嚏反射」的現象，但個人不太認同，畢竟原理上解釋不通啊。自身感覺像是能量物質的攝入導致的，猜測可可和酒精之間應該有什麼相通的地方，而且與其他能量物質有區別（畢竟糖油之類的能量物質都不能引起打噴嚏）。

持續關注話題中。

我也會！！！一直想知道為什麼？？？
