4. Fish-Misgurnus anguillicaudatus: Under the same weight, the calcium content of Misgurnus anguillicaudatus is nearly 6 times that of carp and about 10 times that of hairtail.

5. Bean products-dried bean curd: dried bean curd made by pressing and concentration, with outstanding calcium content in bean products. For example, the calcium content of small fragrant dried fruit can be as high as 7 times that of water tofu.
