There are currently over 7 million people living with heart and circulatory diseases in the UK (British Heart Foundation), so the timely new research from King’s College London, which has shown that purple foods could help with heart health, is very welcome.
And the key to this research are chemicals called anthocyanins, the same chemicals which give certain fruit and veg their purple colour. Anthocyanins are important for the optimum functioning of your heart and cardiovascular system.
Previous epidemiological studies have shown that regular intake of anthocyanins was associated with an 8-12% reduction in the risk of developing hypertension and a 32% reduction in the risk of suffering a heart attack in young and middle-aged women.
This exciting new study demonstrates for the first time that anthocyanins actually cause improvements in the function of endothelial cells in our bodies. Endothelial cells are found in the linings of blood vessels and help to regulate blood pressure and blood flow.
The haskap berry is particularly high in anthocyanins. One of its nicknames is the ‘love berry’ due to its double berry formation; each berry has a purple-blue skin and the two berries are lovingly encased in a further purple-blue outer skin.
At Haskapa we freeze dry our berries to ensure we retain all this natural goodness, so much so that our haskap berries have been shown to have at least 3 to 4 times the anthocyanin content of blueberries.
Taking just one to two teaspoons of Haskapa berry powder each day will provide you with 40 to 80mg anthocyanins... so we like to say that Haskapa is the love berry that’s good for your heart!
