No, Coke is not a reliable cure for a stomach ache. It’s more like a lucky charm made of sugar and bubbles. For some people, it works wonders. For others, it’s a one-way ticket to Spew City. The science is shaky at best.
If you have serious symptoms—vomiting, fever, sharp pain—skip the soda aisle. See a doctor. But for a grumpy tummy after a big meal? A few sips of flat Coke might chase away the grumps. Proceed with playful caution.
