About this study

Official title: Effect of Added Fruit Pomace Fiber and Whole Fruit on Postprandial Glycemia in Apple

The primary objective of the study is to compare the effects of a whole apple, apple juice alone, and apple juice with pomace on 2 hr glycemic response as measured by maximal glucose concentration

Read the detailed description

This study is a randomized, 3-arm, within subject cross-over trial allowing for three acute evaluations of 100% Apple Juice (235 g), 100% Apple Juice with enzyme-treated apple pomace fiber (129 g apple juice with 106 g apple pomace), and raw apple (230 g with skin edible portion - not including core or stem) on glucose and insulin responses in fifty-two healthy men and women aged 20-45 years.

A planned sample size of 70 will be enrolled into the study. This study will require one initial screening visit and 3 study visits. This study will take approximately 3-4 weeks per subject to complete.

The initial screening visit will take ~2 hours and provide subject with the informed consent document and determine subject eligibility through anthropometric measurements, body composition measurement, vital signs, fasting blood glucose test (finger prick), a vein access scale evaluation, online 24-hr diet recall, and completion of a survey relate to general eating, health, and exercise habits. For women, a pregnancy test will be conducted.

If willing and eligible to participate, subjects will be invited to participate in the study for 3 study day visits. Eligible subjects will be instructed to follow a relatively low polyphenolic diet for at least 1-week prior the beginning of the study and continue for the duration of the study.

Each Study Day visit will last about ~3 hours. The day before each of the 3 Study Day visits, subjects will be asked to consume the same dinner meal and record on a food record. At each Study Day visit, subjects will arrive at the clinic after fasting for 10 to 12 hours and in a well-hydrated and well-rested state.

Each study visit will require blood draws throughout the visit. After evaluation of subject's health status (via anthropometric, vital sign and blood glucose measurements and in-person interview), a Licensed Health Care Professional will place a catheter in subject's arm for the purpose of multiple blood sample collections and take the initial blood draw in the fasting state. Subjects will be randomized to receive one of study products based on randomized treatment sequences for 3 study visits immediately after fasting blood draw.

Participants will come to the research site on 3 separate occasions separated by a washout period. On each occasion 2 fasting blood samples will be obtained at 5 min intervals (-5, 0 minute (min)). Subjects will then consume one of the 3 treatments. Further blood samples will be taken at 15, 25, 30, 35, 40, 45, 60, 75, 90, 105 and 120 min. Self-reported visual analog scales (VAS) will be used to measure subject hunger, fullness, desire to eat, and prospective food intake at 0, 15, 30, 60, 90, and 120 min. After completion of all study procedures and data/sample collection for the day, the catheter will be removed and subjects will be evaluated for safety and/or discomfort/symptoms before leaving the study site. They will be given a take-home snack and given written instructions in preparation for the next visit. Study day visits will be scheduled at least 3 days apart but no more than 7 days.

Questions about this trial

What is this clinical trial studying?

A study testing Apple Juice1, Apple Juice2 and Raw Apple in people with Healthy, run by Clinical Nutrition Research Center, Illinois Institute of Technology 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 9 inclusion and 16 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 14 Jul 2020. 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. Some participants in this study may receive a placebo. 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?

Plasma Glucose maximal concentration (Cmax) over 2 hours (time frame: Postprandial 2 hours). 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 14 Jul 2020.
