Plasma BCAA response to mixed-meal ingestion. Plasma concentration of the three branched chain amino acids (BCAA) leucine, isoleucine and valine were measured in healthy control and metabolic syndrome subjects following consumption of a high fat soy or dairy breakfast. A) Time course of BCAA concentrations; healthy control subjects are represented with solid lines and closed squares (■) for the dairy meal and closed circles (●) for the soy meal. Metabolic syndrome (MetS) subjects are represented with dashed lines and open squares (□) for the dairy meal and open circles (○) for the soy meal. B) Area under the curve (AUC); open bars represent soy and closed bars represents dairy meals. The graphs represent mean values ± SEM; n = 10 per group. Ψ = significantly different from baseline within the soy condition irrespective of group P < 0.05. Φ = significantly different from baseline within the dairy condition irrespective of group P < 0.05. ‡ = Significant difference between the dairy and soy conditions irrespective of group P < 0.05.
