中新网4月23日电 近日，一种流传已久的观念再次引起公众关注，即认为豆腐等豆制品因含有钙和草酸，可能导致结石，故结石患者应避免食用。然而，据专家解释，这一说法并不完全准确，结石患者在适量食用的情况下，豆制品并不会对健康构成威胁。
据营养学专家指出，大豆中确实含有嘌呤、草酸和钙等可能与结石形成有关的物质。但当大豆经过加工制作成豆腐、豆浆等豆制品时，其草酸含量相较于大豆本身已有显著降低。而且，豆腐中的钙可以与食物中的草酸结合，有助于防止草酸在体内过量积累，从而在一定程度上降低了结石形成的风险。
值得注意的是，虽然结石患者可以适量食用豆制品，但并不意味着可以无限制摄入。医生建议，结石患者在饮食上应保持均衡，控制豆制品的摄入量，并结合个人病情和医生的指导进行调整。同时，保持充足的水分摄入，以帮助稀释尿液，减少结石形成的可能性。
总的来说，豆制品作为营养丰富的食品，对结石患者并非禁忌，关键在于合理搭配和适量食用。公众在获取健康信息时，应科学理性对待，避免因误解而对日常饮食造成不必要的限制。

Title: CEN Investigates: Debunking Myths, Stone Patients Can Safely Consume Bean Products in Moderation
BEIJING, April 23 – A long-standing belief has recently regained public attention, suggesting that tofu and other bean products, due to their calcium and oxalate content, may contribute to the formation of stones, and thus should be avoided by patients with stones. However, experts clarify that this notion is not entirely accurate, and moderate consumption of bean products does not pose a threat to the health of stone patients.
Nutrition experts point out that soybeans indeed contain purines, oxalates, and calcium – substances that may be associated with stone formation. Nevertheless, during the processing of soybeans into tofu, soy milk, and other bean products, the oxalate content significantly decreases compared to the raw soybeans. Moreover, the calcium in tofu can bind with oxalates in food, helping to prevent excessive oxalate accumulation in the body and, to some extent, reduce the risk of stone formation.
It is crucial to note that while stone patients can moderately consume bean products, it does not imply unlimited intake. Doctors advise maintaining a balanced diet, controlling the amount of bean products, and adjusting according to individual health conditions and medical guidance. Additionally, drinking ample water is essential to dilute urine and decrease the likelihood of stone formation.
In conclusion, bean products, as nutrient-dense foods, are not off-limits for stone patients, provided they are consumed in moderation and as part of a balanced diet. The public should approach health information scientifically and rationally, avoiding unnecessary dietary restrictions due to misconceptions.
