Shocking right? Have you ever wondered why sometimes when you eat pineapples you get the itchy, burning “weird” sensation in your mouth? I for one can relate to this because as much as I love pineapples, I always have to deal with this after eating them. . This sensation is actually caused by an enzyme called bromelain. Bromelain digests protein, and so, it digests the tender skin inside your mouth (your gum, tongue and the roof of your month). Bromelain is usually used as a meat softener when isolated (and your tongue in this case equals meat!) . But not to worry though, the good news is that our bodies quickly regenerate new skin and heals our sore mouth in just a couple of hours. The way to eat as much pineapple as you want without the effect of this enzyme is by properly cutting out all the stem/core (middle hard part) of the pineapple before eating. So if you are like me that loves eating pineapple but always has to deal with the itch afterwards, try this tip.
