Black currants nutrition facts

Incredibly rich in numerous health benefiting phyto-nutrients and anti-oxidants, black currants are indeed one of the very popular summer season berries. Currants are native to central and northern Europe and northern Asia. Black currant plant is a small shrub belonging to the family of Grossulariaceae, of the genus; Ribes and has scientific name: Ribes nigrum. In general, currants grow best in regions where summer is humid but winter is severe and chilling. It is a fast growing, deciduous, small shrub reaching about 5-6 ft tall.

During each season, the shrub bears pendulous chain of small berries. The fruit has size of about 1 cm in diameter, very dark purple in color, almost black, with a glossy skin and a persistent calyx at the apex, and containing 3-10 tiny seeds.
Berries of red, white and pink currants are translucent, sweeter in taste, but less nutritional than black varieties.

Health benefits of black currants

  • Blackcurrants have significantly high amounts of phenolic flavonoid phytochemicals calledanthocyanins. Scientific studies have shown that consumption of blackcurrants have potential health effects against cancer, aging, inflammation and neurological diseases.
  • Black currants have anti-oxidant value (Oxygen radical absorbance capacity- ORAC) of 7950 per 100g. One of the highest among fruits after chokeberries, elderberry and cranberries. The ORAC value for red currants is 3387.
  • These berries are an excellent source of antioxidant vitamin, vitamin-C.  100 g of fresh currants provide more than 300% of daily recommended intake values of vitamin C. Research studies have shown that consumption of fruits rich in vitamin C helps body develop immunity against infectious agents and also help scavenge harmful oxygen free radicals from the body.
  • Black currants are very good in vitamin-A and flavonoid anti-oxidants such as beta carotene, zeaxanthin and cryptoxanthin levels. These compounds are known to have antioxidant properties. Vitamin A is also required for maintaining integrity of mucus membranes and skin, and is also essential for vision. Also, consumption of natural fruits rich in flavonoid anti-oxidants helps to protect from lung and oral cavity cancers.
  • Fresh blackcurrants are also rich in many essential vitamins such as pantothenic acid (vitamin B5), pyridoxine (vitamin B-6) and thiamin (vitamin B-1). These vitamins are essential in the sense that body requires them from external sources to replenish and required for metabolism.
  • They also contain good amounts of minerals iron. 100 g currant berries provide about 20% of daily recommended levels. Iron is an important co-factor for cytochrome oxidase guided cellular metabolism. It is also required for red blood cells production in the bone marrow.
  • Black currants are also very good source of other important minerals like copper, calcium, phosphorus, manganese, magnesium, and potassium which are very essential for body metabolism.
