The Pineapple's Revenge

Why does your tongue tingle after eating pineapple? Turns out, the fruit was 'eating' you! Every time you indulge in fresh pineapple, your tongue and oral mucosa feel a stinging sensation, even a bit numb. Many people assume it's because the pineapple is 'too sour' or 'not washed properly from pesticides,' but the truth is quite fascinating: it's not you eating the pineapple, but the pineapple 'eating you back'! Pineapple juice contains a unique natural enzyme called **'bromelain.'** This enzyme's primary function is to break down proteins. When fresh pineapple comes into contact with your mouth, it starts to silently break down the protein in the surface layer of your tongue and oral mucosa, which is the source of that stinging and rough sensation. But don't worry, it doesn't cause permanent damage to the body. Our stomach acid and digestive enzymes quickly break down this bromelain, and when cooked with heat (like in pineapple shrimp balls or pineapple cakes), the high temperature deactivates the enzyme. Next time before eating pineapple, try soaking it in salt water or cooking it directly, and you can enjoy the deliciousness without your tongue protesting!
