Hallelujah Acres Omega 3 Fat Study

This study has been completed.

This research is being done to study the effect of taking flax seed oil and fish oil on blood lipids in vegetarians following the Hallelujah Diet. Omega 3 fats are important to our health and we want to see how effective both flax seed oil and fish oil are in raising your Omega 3 Score (higher is better). The Omega 3 Score is one of many indicators that may show your personal risk of dying suddenly from a heart attack.

Primary Outcome Measures:
  • Omega 3 Score [ Time Frame: 8 weeks of supplementation before testing ]
    A finger prick blood sample is analyzed for fatty acids, including the amount of omega 3 fats in the blood. The Omega 3 Score is the amount of EPA and DHA in whole blood as a percent of fat.

Enrollment: 13
Study Start Date: January 2012
Study Completion Date: December 2015
Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Flax Oil and then Fish Oil
All people in the study will use the flax seed oil and then the fish oil.
Dietary Supplement: Organic flax seed oil
2 tablespoons of organic flax seed oil are eaten daily for 8 weeks.
Other Name: Flora Flax Oil, organic.
Dietary Supplement: fish oil
5 grams (1 tsp.) of fish oil is eaten per day for 8 weeks.
Other Name: Pharmax LLC Finest Pure Fish Oil

Detailed Description:

This study is being conducted to compare the response of individuals to flax seed oil or fish oil, measured by blood lipids. Especially the amount of the long chain omega 3 polyunsaturated fats EPA and DHA will be tested. An omega 3 score for whole blood will be measured. The omega 3 score is the percent sum of omega 3 fats in the blood.

The hypothesis is that 5 grams of fish oil will increase the amount of EPA and DHA in a person's blood to a protective level, and that 30 grams (2 tablespoons) of flax oil will not change the blood levels of EPA significantly and not change the blood concentrations of DHA at all, even for a person consuming a low omega 6 oil diet and following a vegan diet high in fruits and vegetables.

Most of the testing of flax and fish oil has not been done in vegans. This trial will extend this testing to this subpopulation.
