"The Surprising Reason Behind Pineapple-Induced Mouth Tingling"
A TikTok video has revealed the reason behind the tingling sensation experienced when eating pineapple, explaining that it's caused by tiny needle-like structures called raphides, which contain insoluble crystals of calcium oxalate. These crystals can poke holes in cell membranes, causing irritation in the mouth. The video has gone viral, with some people vowing to never eat pineapple again, while others find the defense mechanism of the fruit intriguing and are undeterred from enjoying it.
