These green vegetables also contain a significantly high amount of calcium, increasing the bone-building nutrients in the food. Collard greens are an excellent source of vitamin K as well, and are often mixed with vegetables like mustard and turnip greens in many mixed green products. All of these vegetables contain a high amount of fiber and antioxidants, and most can be easily digested when cooked.

Broccoli, cabbage and Brussels sprouts are excellent sources of vitamin K, as are celery, leeks and cucumber.
