Medium-chain triglycerides and conjugated linolenic acids in functional yogurts: impact of GIT and potential biological activities

Abstract

In recent years, bioactive lipids particularly medium-chain triglycerides and conjugated linolenic fatty acids have obtained more attention due to their possible applicability in obesity metabolism modulation. These compounds are capable to increase thermogenesis and reduce weight gain through the modulation of key neurohormones such as leptin and adiponectin. The purpose of this work was to develop functional yogurts through the addition of coconut (rich in medium-chain fatty acids) or pomegranate oils (rich in conjugated linolenic acids). The presence of these oils led to a significant alteration in the nutritional value of yogurts, showing a capacity to reduce the accumulation of lipids in hepatocytes and increase the release of triglycerides in adipocytes. These results demonstrate that functional yogurts can be a valuable strategy for obesity prevention.
