Haskapa and Heart Health

by Dr Evie Kemp, Research Director, Haskapa


Each year, the British Heart Foundation (BHF) declares February as National Heart Month in the UK.


Latest statistics from the BHF show there are 7.6 million people living in the UK with heart and circulatory diseases. These diseases, for example heart attacks, cause 27 per cent of all deaths in the UK; that’s nearly 160,000 people each year – or an average of one death every three minutes. We know that helping our clients change their lifestyle can prevent, treat and even sometimes reverse these heart and circulatory diseases.


What about berries and heart health?
There is growing research evidence to suggest a diet containing berries may help us reduce the risk of developing chronic cardiac diseases, such as high blood pressure and heart attacks. It is becoming clear that a group of plant chemicals called anthocyanins are the key to understanding these berry health benefits. Anthocyanins are naturally occurring plant pigments that give fruit and vegetables their deep purple, blue and red colours.
Large population studies have shown that a higher anthocyanin diet is associated with:

  • 32% reduction in the risk of suffering heart attacks in young and middle-aged women[1].
  • 14% reduction in risk of developing non-fatal heart attacks in men[2].
  • 8-12% reduction in the risk of developing high blood pressure[3].

In addition, a major review published in 2017 concluded that eating a diet rich in anthocyanins was associated with a reduced risk of dying from all causes, and specifically from heart and circulatory diseases.[4] An influential 2019 study from King’s College London demonstrated that anthocyanins have a major role to play in how blood vessels in our bodies function, helping to lower blood pressure and improve blood flow.[5]


What’s special about haskap berries?
As a result of their abundant vibrant colour with double blue-purple skin and deep crimson flesh, haskap berries contain at least three to four times more anthocyanins than blueberries.


Haskapa has started commissioning its own clinical research on haskap berries. The first pilot study showing improvements in cognition (word recall and recognition) and diastolic blood pressure in older adults was recently published.[6]


Although there is still no agreed daily intake value for anthocyanins, a recent review paper recommended that we eat 50mg anthocyanins per day for optimal benefit.[7] So, taking just one to two teaspoons of Haskapa berry powder each day will give you your daily anthocyanin boost.
