First of all: spinach also contains other chemicals, including beta carotene, lutein, folic acid, vitamin C, iron, phosphorus, potassium and calcium, which are also involved in the formation of spinach teeth.

Second: when you eat spinach, oxalic acid combines with calcium to form calcium oxalate. Calcium oxalate is insoluble in water. So when you eat spinach, you feel these little crystals floating around in your mouth, which gives it an unusual taste.

matters needing attention

Spinach lovers can boil or steam spinach in boiling water to remove oxalic acid. Or drop a little lemon juice on fresh spinach, because the ascorbic acid (vitamin C) in the lemon juice dissolves oxalic acid.
