Spinach can certainly be eaten with tofu, and is a very classic practice. Dare not eat spinach and tofu friends is estimated to have heard of spinach in the rich oxalic acid, easy and tofu in the calcium reaction, generating insoluble calcium oxalate, loss of calcium, and calcium oxalate is not easy to be discharged by the human body, if the long-term hoarding of more calcium oxalate will be the formation of stones, which may lead to kidney stones. But all this worry is actually not necessary, even if the calcium can indeed react with oxalic acid to generate calcium oxalate, but the amount of its reaction is also very small, the loss of that little bit of calcium is actually not a waste of a large number of soybean products in the calcium.

In addition to the calcium oxalate we may be more concerned about a little bit, in fact, the generation of calcium oxalate is not a lot of quantities, we are not every day to eat spinach and tofu, even if a little bit of intake of the body is also not a big deal, and just to avoid this a little bit of calcium oxalate on the abandonment of the intake of soybean products, vegetables, that in fact, may be even more bad for the body. Vegetables are more or less contain oxalic acid, oxalic acid is the most amaranth, even onions in the oxalic acid content is also very high, that we before if we are not careful to mix vegetables and soy products to eat are harmful to themselves? Naturally not. If you are really worried about the impact of oxalic acid, you can blanch the spinach first, oxalic acid is soluble in water, it is easy to be removed, and then cook, you can reduce the bitterness and astringency, but also to avoid letting the oxalic acid and calcium reaction.
