We\u0026#39;ve 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.

我吃70%的瑞士莲黑巧克力必打喷嚏

我也是……简直是巧克力中可可含量的指南针，拿来巧克力我吃一点，70%以上可可含量的话准打（注意是可可含量不是代可可脂，差别蛮大的），不过也就第一口管用，后面就不打喷嚏了。然后就是酒精，红酒及浓度高一点的白酒喝一小口都打，啤酒一点事儿都没有。其他的物质的话得慢慢补充了。
原因绝对不是过敏，这个我肯定。
另外我也看了英文文献说什么可能是“光喷嚏反射”的现象，但个人不太认同，毕竟原理上解释不通啊。自身感觉像是能量物质的摄入导致的，猜测可可和酒精之间应该有什么相通的地方，而且与其他能量物质有区别（毕竟糖油之类的能量物质都不能引起打喷嚏）。
