Study information
| Primary study design | Interventional |
|---|---|
| Study design | Randomised cross-over trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | |
| Study objectives | 15% sucrose intake is detrimental to insulin action when compared to 5% sucrose intake as part of a eucaloric diet in overweight/obese individuals. |
| Ethics approval(s) | Ethics approval received from the Regional Ethics Committee for Northern Ireland on the 30th October 2007 (ref: HSC REC 3 - REC number 07/NIR03/93). |
| Health condition(s) or problem(s) studied | Overweight/obesity and risk of type 2 diabetes mellitus |
| Intervention | Each subject will undergo two dietary intervention periods, each six weeks long separated by a four week washout period. Both diets are matched for macronutrient profile and differ in their micronutrient profile, in that one will have 5% sucrose and the other 15% sucrose content. |
| Intervention type | Drug |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | Sucrose |
| Primary outcome measure(s) |
Insulin resistance, assessed at the end of each six week dietary period using the euglycaemic hyperinsulinaemic glucose clamp technique. |
| Key secondary outcome measure(s) |
1. Glucose tolerance tests, performed at the beginning and end of each six week dietary period to assess postprandial glucose levels and insulin secretion |
