Beets nutrition facts


Beets nutrition facts

Beets are highly nutritious and “cardiovascular health” friendly root vegetables. Certain unique pigment antioxidants present in root as well as top greens have found to offer protection against coronary artery disease and stroke, lower cholesterol levels in the body and have anti-aging effects.

Botanically, the root vegetable belongs to the beta vulgaris species. Scientific name: Beta vulgarisSwiss chard is another member of the beta genus grown for its edible leaves.


Different cultivars exist; red, orange-yellow and white verities. The unique crimson red color of red beet is due to its
 betalain pigments, such as betanin andbetacyanin. Yellow varieties are rich in ß-xanthin pigment. Both root and top leaves of beet are used for consumption. Choggia beet or candy cane variety has alternative red and white concentric whorls.

Health benefits of beets

  • Garden beet is very low in calories (contain only 45 kcal/100 g), and contain only small amount of fat. Its nutrition benefits come particularly from fiber, vitamins, minerals, and unique plant derived anti-oxidants.
  • The root is rich source of phytochemical compound Glycine betaine. Betaine has the property of lowering homocysteine levels in the blood. Homocysteine, one of highly toxic metabolite, promotes platelet clot as well as atherosclerotic-plaque formation, which is otherwise can be harmful to blood vessels. High levels of homocystiene in the blood results in the development of coronary heart disease (CHD), stroke and peripheral vascular diseases.
  • Raw beets are an excellent source of folates; contains about 109 mcg/100 g (Provides 27% of RDA). However, extensive cooking may significantly depletes its level in food. Folates are necessary for DNA synthesis in the cells. When given during peri-conception period folates can prevent neural tube defects in the baby.
  • It contains significant amounts of vitamin-C, one of the powerful natural antioxidant, which helps body scavenge deleterious free radicals one of the reasons for cancers development.
  • Beet greens (tops) are an excellent source of carotenoids, flavonoid anti-oxidants, and vitamin A; contain these compounds several times more than that of in the roots.Vitamin A is required maintaining healthy mucus membranes and skin and is essential for vision. Consumption of natural vegetables rich in flavonoids helps to protect from lung and oral cavity cancers.
  • The root is also rich source of niacin (vit.B-3), pantothenic acid (vit.B-5), pyridoxine (vit.B-6) and carotenoids, and minerals such as iron, manganese, and magnesium.
  • In addition, the root indeed has very good levels of potassium. 100 g fresh root has 325 mg of potassium or 7% of daily requirements. Potassium lowers heart rate and regulates metabolism inside the cells by countering detrimental effects of sodium.
