The health benefits of blackcurrants
Blackcurrants carry four times the amount of vitamin C as oranges, and double the amount of antioxidants as blueberries.
They also contain a high amount of anthocyanins which, along with the antioxidants, can help strength your immune system, soothe sore throats, and ease flu symptoms. Studies have found that blackcurrants have a direct effect on your body's inflammatory response.
Blackcurrant seed oil contains gamma-linolenic acid (GLA), a type of omega-6 fatty acid that's been said to help ease inflammation in the body. The high GLA and anthocyanin content can help reduce joint or muscle pain.
Grape-based drinks like wine and juice are known to help decrease plaque buildup, but blackcurrant juice is far more potent. Blackcurrant is high in potassium and GLA, which can help lower your blood pressure too. The GLA also helps cells in your heart resist damage and slows down platelet clumping in your blood vessels.
In addition, one study found that blackcurrant powder increased heart blood flow and decreased overall peripheral resistance. This suggests that blackcurrant may help you recover after exercise. Clinical trials with blackcurrants found that they improve eye function, including; the eyes' ability to adapt to the dark, blood flow to the eyes, slowed progression of visual field deterioration in people with glaucoma and symptoms of visual fatigue.
People who do computer work every day may benefit from blackcurrant supplements. One study found that 1 tablespoon of blackcurrant berries reduced visual fatigue two hours afterward.
The significant impact of blackcurrant's impact on exercise performance has been examined by the University of Chichester and featured in a Channel 4 documentary 'Superfoods: The Real Story' in 2015.
Sports scientist Matt Cook studied how consuming blackcurrants could increase the performance of athletes and how they improve the pumping of blood around the body, through the dilation of blood vessels.
