About this study
Official title: The Effect of Pasteurized; Pasteurized and Homogenized and UHT -Treated Homogenized Cow's Milk on Gastrointestinal Symptoms in Sensitive Adults
This study aims to investigate differences in digestion rates and gastrointestinal problems caused by pasteurized; pasturized and homogenized as well as UHT-treated homogenized cow's milks in healthy adults by diary of symptoms, blood glucose and triacylglycerol levels and plasma cytokine levels.
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dietary interventionOther
| Study group | Role | What they receive |
|---|---|---|
| pasteurized milk | Experimental | milk that has undergone pasteurization treatment Receives: Other: Dietary intervention |
| homogenized pasteurized milk | Experimental | Milk that has undergone homogenization and pasteurization treatment Receives: Other: Dietary intervention |

What is being measured
The primary outcome is the main question the study is designed to answer.
Gastrointestinal symptoms (self reported)
Gastrointestinal symptoms (self-reported) as measured by a questionnaire. The questionnaire is devided into seven types of gastrointestinal discomfort, and also includes a possibility to describe a gastrointestinal discomfort outside these seven given alternatives. The severity of the symptoms is self-reported on a three-step scale.
Measured: day 0 - day 5
Secondary outcomes (3)
Plasma triacylglycerols
Measured: 20 min, 40 min, 60 min, 120 min, 180 min, 240 min, 300 min
Plasma glucose
Measured: 20 min, 40 min, 60 min, 120 min, 180 min, 240 min, 300 min

Where is the study taking place?
The record lists 2 sites in Finland. 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?

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?
Gastrointestinal symptoms (self reported) (time frame: day 0 - day 5). 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 25 May 2022.
