Postprandial Glycemia in Orange Products

This study is a randomized, 3-arm, within subject cross-over trial allowing for three acute
evaluations of 100% orange juice (250 g), 100% Orange Juice with enzyme-treated orange pomace
fiber (157 g orange juice with 100 g orange pomace), and raw orange (227 g edible portion of
navel orange) on glucose and insulin response in fifty-two healthy men and women aged 20-45
years.

A planned sample size of 52 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 days. 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. 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.
