We all want to be “strong to the fin-ich cause I eat me spin-ach” but our hero Popeye never mentioned that gritty feeling on the teeth after downing some leafy greens. What is that anyways? Ever felt it? The strange residue left coating your pearly whites after eating spinach? You aren’t imagining it, there is, in fact a unique residue on your teeth.
One byproduct of spinach’s metabolism is oxalic acid. These small crystals do not dissolve in water, so when you eat spinach that is the gritty feeling on your teeth. In large quantities, oxalic acid can be harmful, but it is present in only very small amounts in spinach, so you’re safe. You might feel like you need to whip out the Colgate, but then again, you probably needed to do that anyways.
Plus, the health benefits of spinach drastically outweigh the slight gritty residue anyways. You name me any cancer, I’ll tell you why spinach helps prevent it. Ovarian Cancer? Woman who eat spinach have a 40% lower risk of getting it. Prostate Cancer? Chemical compounds in spinach tell the malignant cells to self destruct. Heart Disease? The A & C vitamins combine to form a water and fat soluble anti-cancer team, preventing cholesterol buildup in your arteries. Memory loss? Spinach helps prevent age-induced memory decline. Anemic? Cooked spinach supplies your body with iron like rain to grass. This is one leafy green your body should not live without.
Don’t take my word for it, take the sailor man’s. Gritty teeth never stopped Popeye and he was strong to the fin-ich.
