Why is eggplant terrible for the kidneys?

Eggplant is considered to be terrible for the kidneys due to its high levels of oxalates. Oxalate is a naturally occurring substance found in plants, animals, and humans, and is eliminated from the body through the kidneys. However, excessive consumption of oxalate-rich foods, such as eggplant, can result in the formation of kidney stones. Kidney stones are hard, crystalline mineral deposits that form in the kidneys and can cause extreme pain and discomfort. Therefore, people with a history of kidney stones or kidney disease are advised to limit their intake of eggplant and other foods high in oxalates to prevent further kidney damage.
