Table 1 Content of linoleic acid (18:2 9c, 12c) and conjugated linoleic acid isomers in non-SARA (control) and SARA diets (g/100 g)

From: Feeding butter with elevated content of trans-10, cis-12 conjugated linoleic acid to obese-prone rats impairs glucose and insulin tolerance

  1. Data presented as mean plus/minus standard deviation, in g/100 g of butter fat or prepared diet (a45 % kcal from butter). The main CLA isomers, 9c, 11t and 10t, 12c are bolded *, significantly different from non-SARA butter (p < 0.05). n = 4 batches of non-SARA butter, and 2 batches of SARA butterb as previously reported [13]
