Spinach and tofu eaten together will produce calcium oxalate precipitation, but precipitation does not lead to stones. Calcium oxalate will not be absorbed by the body, instead because the presence of calcium in tofu binds some of the oxalic acid and reduces the body's absorption of oxalic acid. A major cause of calcium oxalate stones is the combination of free oxalate ions with calcium in the blood, which then undergoes a series of complex changes to form stones. Therefore, spinach and tofu eat together not only does not cause stones, on the contrary, can also reduce the formation of stones.
About eating spinach and tofu together will cause calcium deficiency, is very one-sided. Indeed, because the formation of calcium oxalate will affect the absorption of calcium in the tofu.
