Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
2 X80g high fat muffins (30% fat) containing 21g sucrose per muffin then 2 X80g high fat muffins (30% fat) containing 21g fructose per muffin (in random order one week apart) in 2 acute studies (3 hour study with blood samples taken at baseline, 30,60.90,120,150 and 180 minutes) immediately followed by 4 weeks of 2 X80g low fat muffins (15% fat)/daily containing 21g fructose per muffin followed immediately by a repeat of the two acute studies.
Compliance assessed by checklist and frozen muffin return.

Lifestyle
Comparator / control treatment
The comparator/control are the 2 X80g low fat muffins (15% fat) containing 21g sucrose per muffin consumed daily for 4 weeks by the control participants. The acute tests are the same for both intervention and control.
Compliance assessed by checklist and frozen muffin return.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
allocation to chronic muffin determined by an administrative person
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
order of acute studies, type of chronic muffin and order of second acute studies using random number generator
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Parallel
Other design features
All treatments were delivered to all people in the acute study. For the chronic muffin consumption the design was parallel only.
Phase
Type of endpoint/s
Statistical methods / analysis
Repeated measures ANOVA with time (0-180 minutes and baseline or 1 month) as repeated measures and acute treatment allocation and chronic muffin allocation as factors

Summary
Brief summary
The aim of this study is to see whether fructose elevates triglyceride acutely and whether this gets worse after a month of consumption of fructose muffins. Overweight or obese volunteers underwent 2 acute fat tests over 3 hours with 2 muffins sweetened with sucrose or fructose. This was repeated after a month of consumption of 2 low fat muffins/day sweetened with either sucrose or fructose. Endpoints were area under the curve for triglyceride and glucose and weight
