Food preservation and storage can reduce the consumption of calcium. When milk is heated, don't stir it, add more water and stir it for a short time, and the vegetables should not be too broken. Spinach, water bamboo and leek all contain more oxalic acid, so it is advisable to soak them in hot water for a while to dissolve the oxalic acid, so as not to combine with calcium-containing foods to form insoluble calcium oxalate. Lactose can store more dietary calcium. Sorghum, buckwheat chips, oats, corn and other miscellaneous grains contain more calcium than rice and flour, so you should eat some miscellaneous grains properly at ordinary times.

Zinc mainly exists in marine products and animal offal, and other foods contain little zinc-children's favorite water, staple food and eggs contain little zinc, and vegetables and fruits contain little zinc.
