Water bamboo contains a lot of oxalic acid, and tofu contains more magnesium chloride and calcium sulfate. If both enter the human body at the same time, insoluble calcium oxalate will be generated, which will not only cause calcium loss, but also deposit into stones, so water bamboo can not be eaten with tofu.

In addition, because Zizania latifolia contains more insoluble calcium oxalate, its calcium is not easily absorbed by human body, and it is not suitable for impotence, nocturnal emission, spleen deficiency, stomach cold, kidney disease, urinary calculi or excessive oxalate crystals in urine, diarrhea and so on. Zizania latifolia is rich in dietary fiber, which is also good for the body. However, it should be noted that Zizania latifolia cannot be eaten in large quantities at one time.
