RCT-Olive and MLCT

Details and patient eligibility

About

The type of cooking oil used is a crucial factor influencing dietary quality. The purpose of this study is to investigate the effects of olive oil and MLCT oil intervention on glucose and lipid homeostasis in patients with MetS.

Full description

We conducted a 6-month RCT to evaluate the effects of olive oil and MLCT as cooking oils on glucose and lipid homeostasis in patients with MetS; investigate the changes in lipoprotein subfractions and metabolites using NMR spectroscopy, alongside gut microbiota alterations, to elucidate potential mechanisms; and identify baseline variables associated with the anti-obesity effects of olive oil and MLCT.
