About this study
Potato is one of the world's most popular foods and is widely accepted as a staple food. The objective of this study is to determine the effect of altering commercial blanching and cooling times during manufacture of frozen fries produced by the on blood glucose, satiety and appetite. It hypothesized that the processing regime predetermines the physiologic responses to ingested product and therefore it is possible to produce healthier product lines of potato fries.

What is being measured
The primary outcome is the main question the study is designed to answer.
blood glucose
Glycaemic response will be measured before the treatment (baseline) and at 15, 30, 45, 60, 90 and 120 min after the treatment. The glucose concentration will be measured in capillary blood using portable glucose meter.
Measured: 120 min
Secondary outcomes (1)
food intake
Ad libidum food intake will be measure at 120 min using test pizza meal. The amount of consumed test meal (g) will be converted to the energy (kcal).
Measured: 120 min

Where is the study taking place?
The record lists 1 site in Canada. 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?
blood glucose (time frame: 120 min). 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 18 Dec 2013.
