Scientists are investigating if the extract of a Scottish berry could treat one of the country's most serious health challenges – diabetes.
Experts are exploring if a concentrated capsule form of the blaeberry – a small, dark blue berry which is part of the blueberry family and can be found most abundantly in the north and west Highlands – could be used to combat the disease which affects over 220,000 people in Scotland*.
Overweight male volunteers are being sought for the study which will examine if taking a capsule form of the fruit, improves symptoms in patients with Type 2 diabetes.
Type 2 diabetes develops when the body either does not produce enough insulin – which helps glucose enter the body’s cells, where it is used for energy - or the insulin that is produced doesn’t work properly.
87.4% of diabetics in Scotland have the Type 2 form of the disease, which is closely associated with obesity.
Dr Nigel Hoggard from the University of Aberdeen Rowett Institute for Nutrition and Health, who is leading the study, said: “The exact link between Type 2 diabetes and obesity has never been pinpointed.
“We think the answer to their connection lies in fat tissue. When fat increases, this is associated with a low grade inflammation, and the release of a number of hormones into the blood.
“It is these hormones, and how they act on the glucose in our body, which we believe causes Type 2 diabetes to occur.
“We know that blaeberries – which come from the same family as blueberries – are naturally very high in a chemical substance called polyphenols.
“We believe this substance could reduce the inflammation which occurs when fat increases.
“We’ll be asking volunteers to take a concentrated form of the berry as a capsule three times daily – equating to approximately 1 ½ cups of blaeberries - to test whether this helps reduce inflammation associated with the increased fat tissue, and therefore improve their diabetic symptoms.”
Sixty overweight, male volunteers with Type 2 diabetes between the ages of 40 – 70 who live in Aberdeen city, shire or the surrounding area, are being sought for the 3 week study.
Volunteers must be controlling their diabetes through their diet, rather than insulin.
Dr Hoggard added: “Traditional folk remedies have cited the blaeberry as a natural resource to help combat diabetes for centuries.
“We hope our study will provide scientific evidence of the way in which potentially a local product could help in controlling one of Scotland’s most prevalent diseases.”
