Swiss chard
Swiss chard is also known as silverbeet or simply chard. It is a leafy green vegetable that contains a thick stalk which ranges from red to orange to white in color. It has a high nutritional value and helps maintain healthy functioning of the body. Studies show that 1 cup (175 grams) of cooked chard offers about 20% of the daily requirements for potassium that is more than double the potassium in a banana. 1 cup of cooked chard also contains 476% of the daily value for vitamin K and 60% of the daily value for vitamin A. It contains low levels of calories and high amounts of fiber. You can take Swiss chard as a delicious base for salads, because it is easy to sauté or steam with oil.
