The berries of black currant are rich in polyphenolic compounds and especially in anthocyanins, demonstrating antioxidant activity. Antioxidant activities of plant products contribute multiple health benefits.
What are the potential health benefits of black currant juice?
Black currant juice shows anti-cancer activities. In a study of carcinoma-bearing mice, oral administration of black currant juice and cassis polysaccharide retarded the growth of the solid tumor by 45% and 51% respectively. carcinoma-bearing administration had a stimulatory effect on the release of IL-2, IL-10, interferon-gamma, and IL-4 from splenocytes cassis polysaccharide showed a certain cytotoxicity directly against tumor cells.
It also showed anti-oxidant activities against human LDL oxidation. Enzymatic release of phenolic compounds from pomace remaining from black currant (Ribes nigrum) juice exerted a pronounced antioxidant activity against human LDL oxidation in vitro when tested at equimolar phenol concentrations of 7.5-10 microM.
A study indicates that black currant seed oil, which contains 14.5% alpha-linolenic (18:3n3), 12.6% gamma-linolenic (18:3n6), 47.5% linoleic (18:2n6) and 2.7% stearidonic (18:4n3) acids, could potentially serve as alternative to fish oil as a n3 fatty acid source. This study of 15 healthy females indicates that black currant seed oil supplementation can lower serum levels of LDL cholesterol. In another study, black currant oil (gamma-linolenic acid; GLA) diets lower the blood pressure of SHR rats and help relieve inflammation and enhance the immune systems.
