One thing we don't like spinach is that when you eat a salad made with this green leaf, it will leave a strange chalky feeling on your teeth.If you ever want to know what that feeling is, then you know, not just you. "Spinach Teeth" is true for most of us. it is caused by a large amount of oxalic acid contained in the leafy plant.

Oxalic acid is a chemical naturally occurring in plants, but spinach contains more oxalic acid. Oxalic acid is known as an anti-nutrient because it binds to minerals and prevents the body from absorbing these nutrients. In the case of spinach, this nutrient is calcium.

When you chew spinach, the calcium in the saliva combines with oxalic acid and then forms calcium oxalate crystals. It is these crystals that stick to your teeth and make it feel sandy. It's like a tiny crystal floating in your mouth, so that's why it's different feelings and textures. This is all the feeling.

You can't minimize this feeling, so accept it and eat all the spinach you want. (Of course, unless you have a tendency to form kidney stones. If this is the case, talk to your doctor because it is best not to eat foods rich in oxalic acid.)
