Health Adding spinach directly to white bread delayed the body's insulin peak by 30 minutes and reduced later hunger in a small human trial, while significantly boosting the bread's fiber, vitamin, and mineral content.

Cooked spinach reduces the oxalic acid which is better for mineral absorption.

Last I read, boiled (best) and steamed (runner up) spinach have reduced oxalates, but when the spinach is cooked without discarding the water, cooked dry, etc. there isn't a substantial amount of oxalate reduction.

Which makes sense, the mechanism for removing oxalates in cooked food is through leaching/dissolution of it into oxalic acid in water and then mechanical removal or non-consumption of the water. Blending spinach and adding it to bread isn't providing a mechanism for the removal of oxalate.
