Fat TasteFCandPNCT02357329
Food Composition and Palatability
An observational study of Fat Taste, run by Purdue University at 1 site in United States.
Trial summary
This study will investigate fat taste and if free fatty acids (FFA) in food function as a signal for fat content. FFA are quite unpleasant - the investigators want to measure if the concentration in different foods correlates with hedonic preference. Read more about this study

About this study
This study will investigate fat taste and if free fatty acids (FFA) in food function as a signal for fat content. FFA are quite unpleasant - the investigators want to measure if the concentration in different foods correlates with hedonic preference. FFA concentration from a variety of foods will be used to determine if people who have greater sensitivity for FFA find foods with higher FFA concentrations less acceptable. Further, this study with determine whether the relationship between fat taste and hedonic food preference is modified by sex and body mass index (BMI).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Taste and hedonic ratings of NEFA | Linoleic acid solutions from 0.005% to 1.58%. Participants swish and spit 10 - 7.5mL solutions. |
What is being measured
The primary outcome is the main question the study is designed to answer.
NEFA sensitivity (Participants will taste and rate 10 solutions based on intensity)
Participants will taste and rate 10 solutions based on intensity
Measured: 1 day
Secondary outcomes (1)
Food consumption and preference (Participants will answer questions regarding consumption of foods and preference)
Participants will answer questions regarding consumption of foods and preference.
Measured: 1 day

Questions about this trial
What is this clinical trial studying?
An observational study of Fat Taste, run by Purdue University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
NEFA sensitivity (Participants will taste and rate 10 solutions based on intensity) (time frame: 1 day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2015.
