Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The 26 participants will attend in groups of 1-4. Each participant will be invited to attend 4 study visits with a washout period of ~7 days. In each of the study visits, participants will arrive at the Human Nutirtion Research Unit either in Auckland or Palmerston North, Massey university. They will be given a meal containing potatoes and 40g of fat from cream, Each meal will also contain 1 of 4 ingredients:

A= raw turmeric
B= turmeric powder
C= curcumin powder
D= no curcumin or turmeric

The meals will be equivalent to 400mg of curcumin and matched for moisture and dry weight (using corn starch). All meals contain around 550 kcals (foodworks 9, 2016 NZ food files).

A cannula will be inserted into the forearm of the participant and blood will be taken before the meal is consumed or every hour for 6 hours after the meal is consumed.

The participants will also be asked to fill out an appetite assessment questionnaire before and after the meal is consumed.

The blood will be collected from a cannula by an experienced Massey University staff member
Intervention code [1] 299614 0
Treatment: Other
Comparator / control treatment
Since this is a crossover design trial, each participant will serve as their own control. The control meal will contain potatoes and cream without any turmeric or curcumin
Control group
Placebo

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Since this is a crossover trial, allocation concealment is not applicable. All participants will consume all 4 meals in separate visits.

Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The order in which the meals will be given to participants will be determined using 4 pre-generated unique sequences. Each participant will be randomly allocated to one of the 4 sequences using simple randomization generated from a calculator
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s

Pharmacokinetics
Statistical methods / analysis
The sample size was calculated using G*power (version 3.1.9.2) a priori, 2-tailed t-test, difference between 2 dependent means. The sample size was calculated using an anticipated mean difference between time to maximum postprandial chylomicron triglyceride levels and a standard deviation of 101.6 which was assumed based on a previous study. Based on the calculated effect size, 90% power with a level of significance of 0.05 a minimum of 23 participants would be required for each interventional treatment. Allowing for 10% dropouts and non-compliant participants, we will recruit n=26 male participants for each study.

We will be using area under the curve, Cmax, T-test, anova and repeated measure analysis to measure statistical significance

Summary
Brief summary
The main aim of this study is to investigate if there is a difference in how the bioactive compound curcumin behaves in isolation compared to when it is within turmeric. To test this we will be undertaking a single meal crossover study in healthy male participants and fat-induced blood markers measured.
