Broccoli is a wonder food. High in fiber, it's also a great dietary source of two B vitamins, folate and riboflavin, as well as potassium, iron and vitamin C. Even though it's not orange, broccoli contains high amounts of anti-aging beta carotene and lutein.
All these nutrients boost your health, but some have special functions. Folate is essential for cell reproduction and formation of hemoglobin that oxygenates red blood cells. Like antioxidants, it fights cancer and heart disease. Folate also helps keep your hearing sound by slowing the age-related loss of high-frequency sounds.
Riboflavin aids metabolism, gives you energy, and is necessary to make other vitamins function in your body.
Every cell in your body contains iron. It keeps your red blood cells oxygenated for energy and proper muscle and brain function. But your body needs vitamin C to absorb iron. Broccoli has this in spades.
