There’s one thing we don’t love about spinach, and that’s the strange, chalky feeling it leaves on your teeth after you eat a salad made with this leafy green.
If you’ve ever wondered what that sensation is, know that it’s not just you. “Spinach teeth” is a real thing, and it is a result of the high quantities of oxalic acid found in this leafy green.
Oxalic acid is a naturally occurring chemical found in plants ― but spinach tends to have higher amounts of it. Oxalic acid is referred to as a antinutrient, because it can bond with minerals and block the body’s ability to absorb those nutrients. In the case of spinach, that nutrient is calcium.
Jennifer Moltoni -- administrative coordinator at the Department of Oral Medicine, Infection and Immunity at the Harvard School of Dental Medicine ― told Chowhound that when you chew spinach, the calcium in your saliva combines with the oxalic acid, and then calcium oxalate crystals are created. It is those crystals that stick to your teeth and make it feel gritty.
"It's almost like tiny crystals are floating around in your mouth, so that's what gives it that unusual feeling and texture," Jim Correll, professor of plant and pathology from Arkansas University, explained to Live Science. And that’s all that feeling is.
There isn’t anything you can do to minimize that feeling, so just accept it and eat all the spinach you want. (Unless of course you have a tendency to form kidney stones. If that’s the case, talk to your doctor because it’s best to avoid a diet rich in oxalic acids.)
