Can Cashews Cause Kidney Stones?


Cashews are not typically associated with causing kidney stones. Kidney stones form when certain substances in the urine, such as calcium, oxalate, and uric acid, become highly concentrated and crystallize, leading to stone formation in the kidneys.

Some foods are high in oxalate, a compound that can contribute to the formation of calcium oxalate kidney stones in susceptible individuals. However, cashews are not among the foods considered extremely high in oxalates compared to other sources like spinach, rhubarb, nuts like almonds or peanuts, certain types of beans, and chocolate.

While cashews contain oxalates, they are not considered one of the primary dietary contributors to kidney stones. The impact of dietary oxalates on kidney stone formation varies among individuals, and many factors, including hydration, overall diet, genetics, and underlying health conditions, contribute to the risk of developing kidney stones.

Maintaining a balanced diet, staying hydrated, and monitoring the intake of high-oxalate foods might be beneficial for individuals prone to kidney stones. However, simply consuming cashews in moderation as part of a balanced diet is unlikely to significantly increase the risk of kidney stone formation in most people.

If someone has a history of kidney stones or is concerned about their risk, it’s advisable to consult a healthcare professional or a registered dietitian for personalized dietary recommendations and guidance on managing or preventing kidney stones.
