Researchers say that extract of one of Scotland's most popular wild fruits - the blaeberry - could be used to treat diabetes.
In their study, Aberdeen University scientists will explore the possibility of using a concentrated capsule form of the blaeberry to combat the disease.
To come up with the conclusion, scientists will use overweight male volunteers in the study which will examine whether taking a capsule form of the fruit improves symptoms in patients with Type 2 diabetes.
Lead researcher Dr Nigel Hoggard, from Aberdeen University's Rowett Institute for Nutrition and Health, 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."
He explained: "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."
A university spokeswoman said: "We'll be asking volunteers to take a concentrated form of the berry as a capsule three times daily - equating to approximately 11/2 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 to 70 who live in Aberdeen city, shire or the surrounding area, are being sought for the three-week study."
