NCT01157208

Brief Summary

The purpose of this study is: 1) To assess the feasibility of implementing a clinical trial comparing two potentially analgesic dietary interventions in patients with chronic daily headache (CDH) and 2)To assess the preliminary efficacy of the dietary interventions on headache frequency and severity and 3) to assess the impact of the diet on the percentage of omega-6 highly unsaturated fatty acids (HUFA) in total HUFA in whole blood. During a 6-week baseline phase, eligible individuals with CDH will complete web-based daily diaries, self-report questionnaires, and nutrient intake assessments. Before randomization to one of the two intervention groups, blood will be collected to measure baseline nutritional biomarkers. Targeted dietary advice will be administered and foods will be provided throughout the 12-week intervention phase. Samples for biomarkers will be collected every 4 weeks during the intervention. Participants will continue recording headache characteristics with a daily headache diary. At the conclusion of the intervention, participants will provide complete follow-up assessments and blood for nutritional biomarker measurement.

Outcome Measures

Primary Outcomes (1)

  • Headache Impact Test

    Headache-related quality-of-life measure

    Pre-intervention and post-intervention

Secondary Outcomes (1)

  • Omega-3 and omega-6 fatty acids in RBCs and plasma

    pre-intervention and at 4 and 8 weeks, and at the conclusion of the intervention.

Study Arms (2)

Diet A

EXPERIMENTAL

This diet is high in omega-3 fatty acids, low in trans fatty acids, and low in omega-6 fatty acids. Subjects are encouraged to eat fatty fish daily (e.g., salmon), to limit vegetable oil intake, and to eat fruits, vegetables and whole grains. Specifically formulated and other provided foods for this group will include salmon-salad sandwiches, hummus with olive oil, other bean dips and bean dishes, frozen and canned fish, and blueberry-flax muffins.

Other: Diet A

Diet B

EXPERIMENTAL

This diet is low in trans fatty acids and low in omega-6 fatty acids. Subjects are encouraged to to limit vegetable oil intake, to replace meats and eggs with beans and lean fish/shellfish, and to eat fruits, vegetables and whole grains. Specifically formulated and other provided foods for this group will include hummus with olive oil, other bean dips and bean dishes, lean fish and shellfish,and blueberry muffins.

Other: Diet B

Interventions

Diet AOTHER

Subjects receive dietary counseling, food for two meals and two snacks daily, and access to a website with recipes, approved food lists, and dining out guides for a 12-week intervention.
