Spinach contains an unusually high percentage of _______ acid as a natural product.
Oxalic acid
Oxalic acid is correct.
Spinach naturally contains an unusually high amount of oxalic acid, much of it present as oxalate salts.
Oxalic acid binds calcium to form insoluble calcium oxalate, which lowers the calcium the body can absorb from spinach and, in excess, can contribute to kidney stones. Lactic acid is found in curd and sour milk, citric acid in lemons and oranges, and tartaric acid in tamarind and grapes.
