About

The purpose of this study is to investigate whether there are differences in postprandial cardiometabolic metabolic indices following interesterified fats used commercially versus application appropriate non- interesterifed alternative fat.

Full description

Aim: The current study aims to investigate the acute effects of commercially available interesterified fat versus versus application appropriate non- interesterifed alternative fat on 8 h postprandial cardiometabolic outcomes.

Hypothesis: Interesterified fat will induce a different cardiomtabolic response compared to a non interesterifed, application appropriate fat.

Subjects: Participants will include 40 healthy male and female volunteers aged between the ages of 35 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 20 participants (males and females separately) will allow a 2.16% (percentage unit) difference in FMD to be detected (90% power, 0.05 alpha, SD 2.9. 50 participants will be recruited allowing for a 20% dropout rate.

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