Olives For Health: Benefits of Introducing Table Olives into the Diet

This study, called "Olives For Health," is looking at whether eating table olives can improve the health of young adults. Researchers want to see if adding organic olives to your daily diet for 5 weeks can lower your "bad" cholesterol (LDL) and other health markers. They are looking for healthy college students (freshmen, sophomores, or juniors) between 18 and 23 years old who are willing to eat 6 olives daily. The study aims to see if daily olive consumption leads to a 4.5% decrease in LDL cholesterol levels. The current recruitment status is unclear.

Study design
This is an interventional, randomized clinical trial planning to enroll 226 participants.
What's involved
You would need to consume 6 olives daily for 5 weeks. Blood draws will be taken at the beginning and end of the 5-week period.
Compensation
Not stated in the trial record.
Follow-up
Your health markers will be measured at baseline and after 5 weeks.

  • Change From Baseline in Mean LDL at Week 5at baseline and week 5

    Blood draw to assess LDL at baseline and week five. Change will be calculated by comparing means of the differences (5 weeks-Baseline) between the two study groups, a decrease in the mean from baseline is positive.

  • Compliance/adherence to daily interventionup to week 5

    Assessment and verification of receipt of the olives will be tied to the dining hall card swipe that is part of the student's access to the dining facility, for study participants in the olives group. Swipe=adherent.
