Heart and liver lipid fatty acid and behavior changes in mice after a diet change.
270-Day old, male Ham/ICR mice were subjected to a diet change from high protein and carbohydrate and low fat to a diet higher in fat and lower in carbohydrate and protein. Age matched mice were maintained on laboratory rodent chow as controls. The diet change was not defined so the observed differences could not necessarily be ascribed to altered protein, carbohydrate, or fat intake. Comparison of the controls with the experimental mice revealed the " junk food" mice differed in lipid fatty acid profiles of the heart and liver and in percentage of lipid palmitic and oleic acids in these organs and also in plasma. Appearance was altered in the experimental mice which had dull, greasy coats. In addition, the experimental animals were less active, slept singly, and were slower in negotiating a three-choice maze than their comparably housed counterparts, indicating altered activity/curiosity behavior.
