The effects of whortleberry on controlling of blood glucose and lipids in patients with type II diabetes: A randomized controlled trial

Type II diabetes is the most common metabolic disease in the world. The aim of present study wos to determine the effects of whortleberry on glucose control index and lipid profile in patients with type II diabetes The present study was a randomized trial (IRCT: 1389). The sample was 75 patients with type II diabetes (30 people in intervention and 45 people in control group) in Karaj-Iran. The control groups took placebo capsules (starch) and whortleberry (500 mg، twice a day after breakfast and lunch) was administered in intervention group. Vein blood samples were taken at the beginning and end of study to measure fasting blood glucose، glycosylated hemoglobin (HbA1c)، insulin serum، Triglyceride، total Cholesterol and its contents. Using HOMA Score، insulin resistance was also measured. Descriptive statistics and chi-squared، T- independent، paired T and ANCOVA testes were used for data analysis. After 90 days of the intervention، there was a significant difference in FBS، two hour blood sugar (BS2hpp) and HOMA Score between Whortleberry and control group. Also In whortleberry group، in all glucose control indexes، there were significant differences After 90 days of the intervention. This study demonstrated that using of oral whortleberry supplement for adjusting blood glucose is suitable for patients with type II diabetes patients. Therefore using of it along with medical treatment can be recommended.
