Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate whether there are differences in postprandial metabolic indices following interesterified fats used commercially versus the corresponding un-interesterified blend.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Aim: The current study aims to investigate the acute effects of commercially relevant interesterified 'hardstock' versus the corresponding un-interesterified blend on 8 h postprandial fat metabolism.

Hypothesis: Interesterification of a palm kernel and palm stearin fat blend, to produce a fat with a higher proportion of palmitic acid in the middle position of the triglyceride (TAG; but the same fatty acid composition), will alter postprandial lipid metabolism.

Subjects: Participants will include 24 healthy male and female (postmenopausal) volunteers aged between the ages of 45 and 75 years (since during this age metabolic changes start to take place).

Power calculation: Based on previous studies carried out by our group at King's College London, a sample size of 10 males and 10 females is required to detect a (clinically relevant) difference (for males and females separately) between means of 0.3 mmol/L maximal difference in 8 h plasma TAG concentration (standard deviation 0.33 mmol/L, significance level (alpha) of 0.05 and 80% power). 12 males and 12 females will be recruited to allow for a 20% drop out rate.

Expected value:The study will provide novel information on the acute effects of commercially relevant processed fats on postprandial lipaemia.
