Abstract
Our objective was to compare the plasma fatty acid composition of individuals following the consumption of a diet with full-fat (3.25%) or non-fat yogurt to evaluate commonly used biomarkers of dairy fat intake. This randomized, double-masked, controlled crossover trial compared the consumption of two experimental diets with three daily servings of either full-fat or non-fat yogurt for three weeks each. Fasting plasma samples were taken after each diet period and analyzed for fatty acids using gas-liquid chromatography. Results suggest that common fatty acid biomarkers may not sufficiently represent dairy-fat intake. Branched-chain fatty acids should be explored as alternative.
