Rhubarb is a nutrient-dense, low-calorie vegetable (often treated as a fruit) that is particularly prized for its high Vitamin K1 and fiber content. Historically used in traditional Chinese medicine for over 5,000 years, it is now widely recognized for supporting bone, heart, and digestive health. 

Key Health Benefits
* Bone Health: Rhubarb is an excellent source of Vitamin K1, providing roughly 26–45% of the Daily Value (DV) per cup. Vitamin K is essential for bone formation and may help prevent osteoporosis.
* Digestive Support: High in dietary fiber (2.2g per cup), rhubarb acts as a natural aid for constipation. It contains sennosides, which act as natural stimulant laxatives.
* Heart Health: The fiber in rhubarb stalks helps lower "bad" LDL cholesterol. It also contains anthocyanins and resveratrol, antioxidants that support blood vessel function and may reduce cardiovascular risk.
* Anti-Inflammatory & Antioxidant: Rich in polyphenols, rhubarb helps fight oxidative stress and chronic inflammation. Some studies suggest its total polyphenol content may even exceed that of kale.
* Brain Health: Vitamin K is linked to limiting neuron damage, which may play a role in protecting against Alzheimer's disease.
