Time course of lag time of LDL oxidation with in vitro addition of 6 µmol/L α-tocopherol in older adults after acute intake of skim milk vehicle (C), 225 mg (L), or 450 mg (H) GAE ASP. The data are presented as the percent change from the respective baseline (0 h). The mean baseline lag time was 95.7 ± 2.6 min. Values are expressed as mean ± SEM, n = 7. Means not sharing the same letter at the same time point are significantly different, p ≤ 0.05, tested using PROC GLM followed by Tukey’s HSD multi-comparison test. p-Values of the dose and time effect and their interaction were 0.001, 0.014, and 0.049, respectively.
