Table 4. Plasma and liver lipid status.

Lipid concentrations in plasma and liver of diet-induced obese rats fed high fat diet (HF), high fat diet with 10% w/w pectin (HF+P), low fat diet (LF) or low fat diet with 10% w/w pectin (LF+P) for 4 weeks in two independently replicated experiments. Within rows, means with different superscript letters are significantly different (by Tukey’s post hoc tests).
