Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will arrive at the provider’s laboratory, after an overnight fast. Following insertion of an intravenous catheter, an initial blood sample will be taken into heparin-treated BD Vacutainers as well as gold top vacutainers for serum. Prior to consumption, 1000 mg paracetamol will be added to all of four beverages to be consumed ( in randomised order) and the beverage thoroughly mixed. The subjects will then consume the assigned beverage (within 5 min) in front of the research technician. Seven further blood samples will be taken over 4 hours at times +15, +30, +60, +90, +120, +180, and +240 following baseline. Samples will be separated by centrifugation for 15 minutes (within 15 minutes of collection). Serum and plasma will be aliquoted and stored at -80 degrees till analysed. Participants present on four separate occasions in total and two intervention products and two competitor products will be tested, each one week apart. Beverages include: Dairy milk UHT beverage containing 10% protein, Dairy milk UHT beverage containing 10% protein, competitor Dairy milk UHT containing 10% protein, competitor Dairy milk UHT containing 14% protein.

Following insertion of an intravenous catheter, an initial blood sample will be taken into heparin-treated BD Vacutainers as well as gold top vacutainers for serum. Prior to consumption, 1000 mg paracetamol will be added to all beverages to be consumed in the current session and the beverage thoroughly mixed. The subjects will then consume the assigned beverage (within 5 min) in front of the research technician. Seven further blood samples will be taken over 4 hours. Participants present on four separate occasions in total and two intervention products and two competitor products will be tested, each one week apart.

The sample size is for each level.
Outcome variables (area under the curve (AUC), raw data and difference from baseline) will be analysed using linear mixed model ANOVA.
For the repeated measures analysis, subject, treatment, visit and time will be included in the procedure, in addition to the treatment-by-time interaction, which addresses whether the trajectory over time during the visit differed between treatments. The model for difference from baseline will include the result at baseline as a covariate.
Where the linear mixed model ANOVA results are significant, Tukey’s post hoc analysis will be used for comparisons between treatments. Statistical significance will be set at a level of 0.05.

Summary
Brief summary
On FOUR separate occasions, the subjects will consume randomly assigned beverage (within 5 min) containing one of the FOUR test products. In total two intervention products and two competitor products will be testec, each one week apart. Dairy UHT beverage containing 10% -14% protein will be compared to competitor UHT products containing 10% - 14% protein effect on postprandial amino acid absorption, paracetamol absorption, blood glucose and insulin response.
