Spinach and milk cannot be eaten together.

Spinach contains oxalic acid, and milk is rich in calcium ions. The calcium oxalate produced by the combination of the two is a water-insoluble substance that can produce stones. It also affects the absorption of calcium in milk, so it is not recommended to eat it together. Hope this helps.

Be careful to avoid eating it with spinach, because spinach contains more oxalic acid, and oxalic acid combines with calcium to form insoluble calcium oxalate, which will affect the absorption of calcium.
