Cardiovascular Health

Section reviewed by Astghik Grigoryan

Potatoes are a good source of nutrients that can help improve blood pressure and promote fullness. However, the scientific evidence on the effects of eating whole potatoes on body weight and disease risk is inconsistent. Further studies, particularly randomized controlled trials, are required to determine the specific impact of potato consumption on health outcomes and disease states (3).

Research has shown that both rutabagas and russet potatoes contain potassium and fiber, which can effectively lower risk factors for cardiovascular disease. However, further research is required to establish the extent of their benefits (4,5).

Cancer

Rutabaga is high in glucosinolates and vitamin C, which have antioxidant properties. They've been shown to reduce inflammation and may even lower your risk of breast cancer (6).

There have been several test-tube studies on russet potatoes' antioxidants and cancer-prevention properties; however, more human-based research is required before making any health recommendations (7).

Bowel Health

As mentioned above, rutabaga is an excellent source of insoluble fiber. A diet rich in insoluble fiber may help soften stool and promote bowel movements. Besides, this type of fiber is a food for the gut microbiome. Hence, rutabaga consumption may also promote the growth of friendly bacteria in your large intestine (10).
