Hi K. Kokoruz! I had no idea either, so I did a search for you and came up with this info:
Question: What is the difference between a turnip and a rutabaga?
Answer: A rutabaga was called a Swede or yellow turnip, until 1967 when its name was changed to avoid confusion with the turnip. Rutabagas are larger, yellow fleshed with a purple top and are usually waxed for winter storage.
A turnip is a smaller cousin of the rutabaga. It has white flesh, with a purple trimming. It has a sharper taste and is most frequently available during the summer before the new crop of rutabaga.
A 3/4 cup serving of cubed rutabaga has only 47 calories, is an excellent source of Vitamin C, a good source of fibre and small amounts of calcium, iron, potassium. Check Food and Nutrition, Fruit and Vegetables section, for a recipe to cook rutabaga in the microwave.
