Glycaemia evolution. Values are mean±SEM of 6 rats per group. Statistical analysis was performed using least significant difference test. *HFD vs. C, #HFD vs. HFD-Alg, †HFD vs. HFD-Ext, and ‡HFD-Alg vs. HFD-Ext were considered significantly different at P<0.05. C, control; HFD, high-fat diet; HFD-Alg, high-fat diet supplemented with 1% algae; HFD-Ext, high-fat diet supplemented with 1% algae extract.
