Consuming Grass Finished Lamb Improves Blood Plasma ω-3 Fatty Acid Response Among Healthy Consumers.

September 20, 2024 updated by: Lynda Perkins, Queen's University, Belfast

The Effect of Consuming Grass Finished Lamb Meat on Omega-3 Blood Response Among Healthy Consumers

This study will investigate the impact of consuming grass-finished lamb meat on blood omega-3 PUFAs and cardiovascular risk factors compared to concentrate-finished lamb meat. Healthy volunteers will consume three portions of lamb meat/week from a grass-finished meat treatment or a concentrate-finished meat treatment for four weeks. Blood samples will be taken at weeks zero and four. The primary outcome is to assess difference in change in omega-3 PUFA concentration in plasma and platelets between treatment groups. The secondary outcome is to assess between groups differences in change in cardiovascular disease risk factors including blood pressure, BMI and lipids among healthy individuals.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
34

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Healthy male and female volunteers aged between 18-64 years old.

Exclusion Criteria:

  • Participants with a BMI of <18.5 km/m² and greater than >35 km/m².
  • Participants who take prescribed medication, including statins to reduce LDL cholesterol, and any form of dietary supplements (excluding vitamin D).
  • People who smoke.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Concentrate/ Cereal fed lamb
Participants to consume three portions of lamb per week for four consecutive weeks. The lamb diet was a concentrate/cereal pellet.
Experimental: Grass fed lamb
Participants to consume three portions of lamb per week for four consecutive weeks. The lamb diet was grass only.
Other: Grass fed lamb
This study investigated the impact of consuming grass finished lamb on total blood plasma and blood plasma phospholipids (PL) FA and on cardiovascular risk factors, including heart rate, blood pressure (BP), HDL-cholesterol, LDL-cholesterol, and TAG cholesterol, in humans.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Fatty acid (%) change in blood plasma between treatments
Time Frame: Week 0 and week 4
Primary outcome is to assess the impact of consuming grass vs concentrate finished lamb on blood plasma response in healthy volunteers
Week 0 and week 4
Fatty acid change (%) in blood plasma phospholipids between treatments
Time Frame: Week 0 and week 4
Primary outcome is to assess the impact of consuming grass vs concentrate finished lamb on blood plasma phospholipid response in healthy volunteers
Week 0 and week 4

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in weight (kg) in participants between treatments
Time Frame: Week 0 and week 4
Secondary outcome is to assess the impact of consuming grass vs concentrate finished lamb on weight among healthy volunteers
Week 0 and week 4
Change in Body Mass Index (BMI) in participants between treatments - calculated by dividing weight (kg) by height in meters squared
Time Frame: Week 0 and week 4
Secondary outcome is to assess the impact of consuming grass vs concentrate finished lamb on weight and BMI response in healthy volunteers
Week 0 and week 4
Cholesterol
Time Frame: Week 0 and week 4
Secondary outcome is to assess the impact of consuming grass vs concentrate finished lamb on total cholesterol, LDL, HDL and TAG response in healthy volunteers
Week 0 and week 4
Blood pressure (diastolic and systolic)
Time Frame: Week 0 and week 4
Secondary outcome is to assess the impact of consuming grass vs concentrate finished lamb on blood pressure (diastolic and systolic) response in healthy volunteers
Week 0 and week 4
