The second category is more oxalic acid containing vegetables, such as spinach, bamboo shoots, wild rice, etc., oxalic acid in the intestinal tract will be combined with calcium into a difficult to absorb calcium oxalate, interfering with the body's absorption of calcium. Therefore, before mixing cold must be blanched with boiling water to remove most of the oxalic acid. The third category is mustard vegetables, such as cabbage
