The ingredient that makes hot chilies hot is called capsaicin—and it can set your mouth on fire. 让辣椒产生辣味的成分叫做辣椒素，它会让你的嘴巴冒火。 But the spicy compound has a soothing effect too: in your gut, it kicks off a chemical cascade that might calm the immune system and reduce inflammation. 不过这种辛辣的化合物也有舒缓作用：它会在肠道中触发一种化学级联反应，这种反应可以稳定免疫系统并减少炎症。 Researchers studied that phenomenon in mice. Once inside the gut, the capsaicin molecules plugged into a specific receptor, spurring the release of another compound, called anandamide. 研究人员在小白鼠身上对这一现象进行了研究。一旦进入肠道，辣椒素分子便会进入一种特殊的受体，促进另一种名为“大麻素”的化合物的释放。 |
