Table 3 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 lean rats does not impair glucose tolerance or muscle insulin response

Data presented as mean plus/minus standard deviation, in g/100 g of butter fat or prepared diet (*60% kcal from butter). The main CLA isomers, 9c, 11 t and 10 t, 12c are bolded. ^asignificantly different from non-SARA butter (p < 0.05). n = 4 batches of non-SARA butter, and 4 batches of SARA butter.
