Plain English summary of protocol

Background and study aims
Palmaria palmata (P. palmata) is an Irish seaweed also called dulse. It has always been consumed over the years and is generally regarded as safe. There is evidence suggesting that it can have a role in promoting health but this has not been studied formally. This study will compare normal bread with bread enriched with 5g of dulse and will note any changes in markers of health.

Who can participate?
Healthy adults.

What does the study involve?
Participants are randomly allocated to one of two groups: the treatment group (bread containing 5 g P. palmata) or the placebo group (bread without P. palmata). They have to eat 1 bread roll (230 g) per day for 28 consecutive days.

What are the possible benefits and risks of participating?
This study will help understand the effects of consuming Irish seaweed on human health. No foreseeable risks are involved.

Where is the study run from?
University of Ulster in Coleraine, Northern Ireland (UK).

When is the study starting and how long is it expected to run for?
August to December 2011.

Who is funding the study?
The Irish Marine Institute and the Department of Agriculture

Scientific titleThe effect of consuming Palmaria palmata enriched bread on inflammatory markers, antioxidant status, lipid profile and thyroid function in a randomised placebo controlled intervention trial of healthy adults
Study acronymSEAPALM
Study objectivesConsumption of P. palmata will favourably alter biomarkers of inflammation and other markers of health (lipid profile, thyroid function and antioxidant status)
Ethics approval(s)Research Ethics Committee of the University of Ulster; ref: REC/11/0078
Health condition(s) or problem(s) studiedInflammation in healthy adults - cardiovascular disease risk
InterventionPalmaria palmata incorporated (5g) into bread (230g total) vs bread alone

Participants were randomly assigned to either the treatment group (bread containing 5 g P. palmata) or placebo group (bread without P. palmata) using an online randomization software (www.randomisation.com) which was determined prior to participant recruitment. Treatment and control breads were labelled and allocated to participant ID according to the randomisation sequence output by an independent researcher not involved in the design or the analysis of the study to ensure that the study was double-blinded to both researcher and participants.
Intervention typeOther
Primary outcome measureC-reactive protein- cytokine analysis
Secondary outcome measures1. Lipid profile - (cholesterol; triglycerides)
2. Thyroid function - (thyroid stimulating hormone (TSH))
3. Antioxidant status - (ferric reducing antioxidant power (FRAP))
