Rutabaga (Brassica napus L.; Napobrassica group), also referred to as swedes, Swedish turnips, and turnip-rooted cabbage, is a member of the Cruciferae. The word “Rutabaga” comes from the Swedish “rotabagge,” which means root ram, baggy root, thick root and ram’s foot. Rutabagas are only called rutabagas in the U.S. throughout the rest of the world, they’re known as swedes. This root vegetable is supposed to have originated in Bohemia in the 17th century as a hybrid between the turnip and wild cabbage. Not to be confused with its relative the turnip; rutabagas are actually larger, denser and higher in many essential nutrients. American Purple Top Rutabaga, Joan Rutabaga, Laurentian Rutabaga, Marian Rutabaga, Heirloom and Gourmet Rutabaga are some of the popular varieties of Rutabaga.

High fat diet is one of the most common reasons for developing prostate cancer whereas cruciferous vegetables like rutabaga, cabbage, kohlrabi, Brussels sprouts, watercress and mustard greens are the best options for reducing the risk of prostate cancer.(1)
2. Diabetes and Weight Loss
However rutabagas plays role of potatoes in several food items, they don’t have much carbohydrates, which break down into simple sugars, possibly wreaking havoc on glucose and insulin levels in the body.

Rutabagas are one of the great options for many vegetarians, as it provides a complete protein, something that most vegetarians struggle to acquire when they don’t consume meat. Proteins and amino acids are actually the building blocks of new cells and are essential to encourage proper development, growth, healing, reproduction, muscle contraction, and dozens of other important bodily processes.(3)
4. Improves Digestion
Just like other cruciferous vegetables, rutabagas are naturally very high in fiber. One cup rutabaga has over 8.42% of your daily fiber requirement, making it one of the most dense high-fiber foods. Dietary fiber improves digestion by bulking up the stool and encouraging elimination, so rutabagas can provide natural constipation relief. Research in the World Journal of Gastroenterology showed that dietary fiber intake can obviously increase stool frequency in patients with constipation.
Several researches suggest that getting more fiber in your diet may play a role in the treatment of conditions such as gastrointestinal disease, stroke, hemorrhoids, high cholesterol, diabetes, heart disease and some forms of cancer. Rutabaga’s powerful punch of dietary fiber makes it a smart choice for your overall well-being.(4), (5)

It’s also an electrolyte, a substance that conducts electricity in the body, along with sodium, chloride, calcium and magnesium.
For proper functioning of the heart, potassium is crucial and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function. People who consume potassium in their diets have a lower risk of stroke, especially ischemic stroke. Rutabagas consist of 427 mg of potassium which is 9.09% of the daily recommended value.(7)
7. Enzymatic Function
Zinc present in rutabaga is a key component of many enzymatic functions throughout the body, without which our bodily processes become inefficient, resulting in more dangerous health concerns. The moderate amounts of zinc found in rutabagas are highly praised for this reason. Rutabagas consist of 0.34 mg of zinc which is 3.09% of the daily recommended value and is normally recommended to include it in your regular diet.(8)

Rutabagas consist of considerable amount of Vitamin C which is extremely important for many bodily processes, like stimulation of the immune system to produce white blood cells, which fight against bacteria and infection. Vitamin c helps to improve the outcome of pneumonia, malaria and diarrhea infections. Overall, vitamin C plays an important role in immune function and the modulation of resistance to infectious agents, reducing the risk, severity and duration of infectious diseases.
