Summary

This trial will study the effects of two types of olive oil on cardiovascular disease risk factors.

Who is the study for?
This trial is for generally healthy men and women aged 20-45 with a BMI of 18.5-29.9 or ≥30 for obese individuals. Exclusions include smokers, heavy alcohol users, drug users, those unable to consent, pregnant/lactating women, people with high cholesterol or blood sugar levels, olive allergies, extreme diets/exercise habits, certain chronic diseases or medication use.
What is being tested?
The study aims to see if consuming low-polyphenol versus high-polyphenol olive oil affects cardiovascular health markers like good/bad cholesterol levels, inflammation indicators and gene expression related to heart disease risk in healthy/overweight and obese participants.
What are the potential side effects?
While not explicitly stated in the provided information, potential side effects may include digestive discomfort due to changes in diet from introducing different types of olive oils.
