Values are the mean ± SEM. NS, p > 0.05. ¹ LC, lean rats fed a control diet with palm oil; LPO, lean rats fed a diet with poppy seed oil; LHO, lean rats fed a diet with hemp seed oil; OC, obese rats fed a control diet with palm oil; OPO, obese rats fed a diet with poppy seed oil; OHO, obese rats fed a diet with hemp seed oil. ^a–c Mean values within a column with different superscript letters were shown to be significantly different (p < 0.05); differences among the groups are only indicated with superscripts in the case of a statistically significant interaction O × T and differences between the oil type (p ≤ 0.05).
