回复：找到一篇豆腐凝固剂文章

I recall that a post was posted here 8 years that Tofu is not a healthy food for human being in particular for male because Tofu contains a significant amount of gypsum. The stomach systems cannot digested gypsum, so that calcium in Tofu (in gypsum) cannot be absorbed as a nutrition element by human beings. The very bad effect is that the very fine crystals (<200 mesh) of gypsum can absorb calcium ion in stomach fluids and thus deplete calcium in the human system, resulting in calcium deficiency.

Please recognize this fact, and do not fool people to suggest them to take Tofu as a source to supplement calcium!!! If possible, read the labels carefully to see if it contain gypsum. If yes, do not buy it. The other consolidated gradients may be ok. That is why Japanese produce Tofu without using gypsum.

I hope that Tofu producer in China will ban gypsum in manufacturing Tofo so that Chinese people would benefit this type of Tofu without any gypsume, and enjoy the taste of Tofu without worrying about the hazard material of gypsum.
