Brief Summary

The study aims at investigating the effects of the consumption of Moringa oleifera Lam leaves on biomedical markers of health among healthy individuals who are hyperglycaemic with a fasting blood glucose equal or greater than 5.5mmol/L.

The main objectives are as follows:

1. To determine the effect of consuming 4 grams of Moringa oleifera Lam leaves infused in 200 ml of hot water twice daily on blood glucose level [BSc (Hons) Medical Science Student].

2. To assess the effect of consuming 4 grams of Moringa oleifera Lam leaves infused in 200 ml of hot water twice daily on plasma lipids level [Master of Public Health Students].

3. To compare the effect of the Moringa tea consumption on lipid profiles of both healthy and hyperglycemic participants [Master of Public Health Students].

4. To evaluate the effects of Moringa oleifera Lam leaves on blood anti-oxidant status [BSc (Hons) Nutritional Sciences Student].

The research work will consist of (1) Experimental intervention: The experimental group will drink Moringa tea; (2) Survey questionnaire, (3) Anthropometric measurements, (4) Blood pressure determination and (5) Blood collections at 15-day intervals during 9 weeks. The blood tests to be performed are as follows: Glucose, HbA1C, Uric acid, C-Protein reactive, Lipid Profile (Total Cholesterol, HDL Cholesterol, Triglycerides), and blood antioxidants (superoxide dismutase, glutathione peroxidase, total blood anti-oxidant capacity).

Detailed Description

Study population

120 participants to include 60 healthy individuals and 60 individuals who are hyperglycaemic with a fasting blood glucose equal or greater than 5.5mmol/L will be recruited by means of flyers, posters and mass email by the help of Staff Club of the UoM.

Experimental design

This research work will to be undertaken under the responsibility and coordination of the Applicant who is the Principal Investigator working with two Academic Supervisors for the supervision of the four student projects.

This randomized clinical study will consist of two parallel groups with a crossover design.

There will be two arms as follows for each group:

1. Intervention group [drinking Moringa tea] and

2. Control group [drinking plain water].

Computer-generated random numbers will be used for simple randomization of subjects to either the experimental or control (equal amount of water) groups. Half of the participants will be assigned to the experimental group and the other control (water) for the first 4 weeks during Phase 1.

The experimental group will be provided with Moringa tea bags and instructed to consume twice daily 2 tea bags (4 tea bags equivalent to 8 grams) of Moringa tea (Kanhye brand) infused in 200 ml of hot water (during 5 minutes) for a period of 4 weeks. The locally available Moringa tea with the international certification by ECOCERT France will be used in this study.

With the cross over design, there will be two phases for both healthy and hyperglycaemic groups with an interchange of the groups during Phase 1 and 2 as follows:

Four-week Phase 1 - Group A drinking Moringa tea v/s Group B drinking plain water One-week washout Four-week Phase 2 - Group A drinking plain water v/s Group B drinking Moringa tea

The duration of the clinical study will normally be nine weeks with possible extension of four weeks.

Outcome Measurements Baseline data collection Measurements of body weight and blood pressure will be performed. Anthropometric measurements will be taken for each subject: Weight will be measured using an electronic weighing machine, height will be measured using a stadiometer, waist circumference will be measured using a non-stretchable measuring tape. Blood pressure will be measured using a sphygmomanometer.

Blood samples will be drawn by Specialized Nursing Officers from right or left ante-cubital vein of participant after a 12-h overnight fast. Blood tests which will be performed are as follows: Glucose, Lipid profile [Triglycerides, Total Cholesterol and HDL Cholesterol levels (LDL Cholesterol being calculated)], Uric Acid, HbA1C, C-Reactive Protein (hs-CRP) and Blood anti-oxidants (superoxide dismutase, glutathione peroxidase, total blood anti-oxidant capacity).

Fortnight monitoring sessions All participants of the two groups will be monitored on a fortnight basis for body weight, height, waist circumference, blood pressure and specified blood tests. Food intake and physical exercise questionnaires will be collected from participants to determine confounding factors.

[The individual quantity of physical activity, in metabolic equivalent-minutes per week (MET-min/week), will be determined by using validated physical activity questionnaire].
