Spinach is genuinely nutrient-dense, but it's also wrapped in myths. Here's an honest look at what this leafy green actually does for your body, and what it doesn't.
Iron-deficiency anemia leaves people tired, headachy, and dizzy, and those who menstruate are among the most at risk. Spinach does contain iron, but it's non-heme iron, the plant form, which the body absorbs less efficiently than the iron in meat, especially because spinach's oxalates further limit absorption. Pairing spinach with a source of vitamin C helps your body take up more of it. It's a useful contributor to iron intake, just not the powerhouse the Popeye myth suggests.
