Actually, it's not a 'part' of the tomato that causes kidney stones, but rather the oxalates present in tomatoes, especially in the seeds and skin, that can contribute to calcium oxalate stones. However, for most people, the amount isn't significant enough to cause issues unless they are already prone to stones or consuming them in very large quantities. Focus on hydration overall.

The oxalates in tomatoes, especially seeds and skin, can contribute to kidney stones, but usually only if you're predisposed.

It's the oxalates present in tomatoes, particularly in the seeds and skin, that can be a factor in kidney stones. But honestly, for active people, staying well-hydrated is usually more important than completely avoiding tomatoes. If you're susceptible to stones, your doctor might advise caution. Regular exercise also promotes kidney health.

Tomato ke seeds aur chhilke mein oxalates hote hain na, usse sometimes kidney stone ka risk badhta hai. Ho na? But generally, it's not a big problem unless you eat too many, ya already stones ka issue ho. Pani zyaada piyo, that's always good.

It's the oxalate content, particularly concentrated in the seeds and skin of tomatoes, that's often linked to kidney stones. However, for most individuals, the amount isn't high enough to be a primary concern. People prone to calcium oxalate stones should monitor their overall oxalate intake, but rarely need to eliminate tomatoes entirely. Hydration is key.

It's not a specific 'part' of the tomato, but the presence of oxalates, particularly in the skin and seeds, that can contribute to kidney stones. However, the contribution from tomatoes is generally minimal for most people. If you have a history of kidney stones, it's always best to consult a nephrologist for personalized dietary advice, rather than self-restricting.
