Rhubarb, raw

Fun Facts

  1. Rhubarb is one of the least calorie vegetables. 100 g fresh petioles carry just 21 calories. Nonetheless, it holds some vital phyto-nutrients such as dietary fiber, poly-phenolic anti-oxidants, minerals, and vitamins. Further, its petioles contain no saturated fats or cholesterol.
  2. The stalks are rich in several B-complex vitamins such as folates, riboflavin, niacin, vitamin B-6 (pyridoxine), thiamin, and pantothenic acid.
  3. As in other greens like kale, spinach, etc., rhubarb stalks too provide good amounts of vitamin-K. 100 g of fresh stalks provide 29.3 µg or about 24% of daily recommended intake of this vitamin. Vitamin K has a potential role in bone health by promoting osteotrophic (bone formation and strengthening) activity. Adequate vitamin-K levels in the diet help limiting neuronal damage in the brain; thus, has established role in the treatment of Alzheimer’s disease.
  4. Its stalks also contain healthy levels of minerals like iron, copper, calcium, potassium, and phosphorus. However, most of these minerals do not absorb into the body as they undergo chelation into insoluble complexes by oxalic acid, which then excreted out.
