Dark coloured foods like black currants are full of antioxidants and the darker the colour, the more antioxidants they contain.
The purple colour of these berries means that they have a high concentration of flavonoids (including resveratrol) which can help decrease blood pressure by relaxing arterial walls and allowing better circulation. Animal studies have found that resveratrol is also responsible for inhibiting the spread of some cancers.
The purple pigment in black currants also contains polyphenols that can reduce inflammation in the body. As well as polyphenols, anthocyanins are found in high concentrations in black currants. Anthocyanins are believed to reduce stomach ulcers as well as preventing oxidation and boosting the activities of other important antioxidants. Black currants are especially known for having more anthocyanins than blueberries and can lower bad LDL cholesterol up to 13 per cent while raising good HDL cholesterol.
