Spinach is often hailed as a superfood, rich in iron, vitamin A, and vitamin K. A cooked cup contains 6.4 milligrams of iron, more than duck or pork. However, experts say meat is more effective for raising low iron levels.
The key difference lies in iron types. Spinach contains non-heme iron, which the body absorbs at a rate of only 2 to 10 percent. In contrast, heme iron from meat, fish, and poultry is absorbed at up to 30 percent.
Iron deficiency affects about 14 percent of American adults, causing fatigue, headaches, and other symptoms. While plant-based diets can meet iron needs, they require careful planning. Pairing spinach with vitamin C-rich foods like oranges or bell peppers can boost absorption.
For those with low iron, experts recommend combining heme and non-heme sources or considering supplements under medical advice.
