Patient's question:
My mother said that a few days ago she discovered lower back pain and stomach pain. When she went to the hospital for a check-up, they said she had kidney stones. My mother usually likes to eat tofu. She heard from others that eating tofu frequently can lead to kidney stones, so she said maybe it's because she heard that tofu can supplement calcium, she won't eat so much tofu.Doctor's answer:
Hello, eating tofu frequently does not cause kidney stones. The formation of kidney stones is related to many factors, but patients with kidney stones should eat less tofu. The factors or causes are that soy products contain high levels of oxalates and phosphates, and excessive intake can easily form calcium oxalate and phosphate crystals, thereby worsening the condition. The oxalates in soy and legume foods can combine with calcium in the kidneys to form stones, which is harmful to the body.
