High consumption of very salty instant noodles promotes the formation of kidney stones, and it is recommended to limit these foods while staying sufficiently hydrated (with lemon) to prevent this risk.

The link between excessive sodium intake and an increased risk of kidney stones is widely documented in scientific literature. Sodium increases the excretion of calcium in urine, which promotes crystallization (source: meta-analyses and observational studies published in journals such as 'Journal of Urology'). It is accurate that instant noodles are ultra-processed foods very high in salt, making them a credible vector for excessive sodium intake. The addition of lemon is also supported by research: the citrate contained in lemon can inhibit the formation of calcium oxalate stones by binding to urinary calcium (source: randomized clinical trials). The claim does not contain major exaggerations regarding the biological mechanism, although it simplifies the fact that stone formation is multifactorial (genetics, overall hydration, other dietary intake). The 'worst pain' aspect is a common subjective experience reported by patients, without being scientific data in itself, but the medical urgency associated with renal colic is very real.
