Detailed Description
The study will be conducted for 3 months (12 weeks) with 58 individuals diagnosed with type 2 diabetes mellitus. The randomisation will be carried out by using a randomisation list. Cinnamon bark (cinnamon cassia) and starch flour (placebo) capsules will be purchased from a local pharmaceutical company in UK; these are freely available for over the counter use. Each capsule contained either 500 mg of cinnamon powder or starch flour. The cinnamon and placebo (starch flour) capsules will be packaged in a non transparent plastic bags.
The patients will be randomly allocated into the two groups of:
Group 1: placebo control group Group 2: cinnamon group
Patients in both placebo and cinnamon groups will receive treatment similar to the treatment they would normally receive from their respective NHS or primary care trust for 12 weeks.
Data collection:
After the randomisation the subjects will be scheduled to visit the clinic at 0 weeks, 6 - 7 weeks and 12 weeks from the beginning of the study. During every visit (week 0, weeks 6 - 7 and week 12) a 3-day diet diary will be collected and the intake of total calories, fats, carbohydrates, proteins and fibre will be determined. Compliance with the diet will be monitored by individual discussions at each clinical visit with dietician and compared with the diet diary. The anthropometric measurements of body weight, height, waist and hip circumferences will be measured before the trial (week 0), during the trial (weeks 6 - 7) and after the trial (week 12) period. The recorded clinical measurements of blood profiles include HbA1c level, fasting plasma glucose concentration and serum lipid profiles including serum total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL) and serum triglycerides, systolic and diastolic blood pressures will be measured at the baseline (week 0) and at 12 weeks during the study period.
