Popeye's spinach habit didn't just pump up his instant muscles. The leafy green also helped him fight off osteoporosis, heart disease, arthritis, and several types of cancer. Plus it's loaded with vitamins, minerals, fiber, and antioxidants -- ranking third behind garlic and kale.
Traced to fourth-century Persia, this hearty annual made its way to China and Europe before arriving in the United States, now one of the world's largest producers. Popular "a la Florentine" dishes pay tribute to spinach's royal heritage as the favorite vegetable of Catherine de Medici.
This super food is packed with heart-friendly A and C vitamins, folate, and magnesium, and it's also low in calories. However, spinach contains a chemical called oxalic acid, which binds with iron and calcium and reduces the amount your body can take in of these minerals. To improve iron absorption, eat your spinach with vitamin C-rich foods such as orange juice, tomatoes, and citrus fruit.
The Scoop on Folate
You can also find this B-complex vitamin in asparagus, beets, calf's liver, and lentils.
