5. Broccoli
One of the greenest members of the cruciferous, or cabbage, family of vegetables, broccoli delivers almost 10% of your recommended daily value of potassium with each cup. Not only that, but you’re loading up on over 100% of your Vitamin C and valuable amounts of folic acid, Vitamin A, and cancer-fighting antioxidants.
Surprisingly, broccoli is over 80% water, making it a low calorie staple for any healthy diet. Broccoli retains most of its nutritional value when consumed in the raw or after being steamed for just a few minutes.
