Rutabaga — a root vegetable from the cruciferous family, which has been part of the diet of various peoples for centuries as an accessible source of energy, vitamins, and minerals.
Due to its low calorie content, moderate carbohydrate content, and high fiber content, rutabaga is suitable for weight management diets and can be used in moderate amounts even in low-carb and keto approaches, provided that portion size and overall carbohydrate limits are considered.
History and Origin
Rutabaga was cultivated long before the spread of potatoes, serving as a staple root vegetable in Europe and Asia. It was valued for its hardiness, ability to be stored in winter, and its filling nature.
