The behavioral effects and effects on serum cholesterol of diets containing different fats were studied in Long-Evans hooded rats. Adult males were fed one of four diets: AIN-76A, Group CON; AIN-76A plus 20% safflower oil, Group POLY; AIN-76A plus 20% coconut oil, Group SAT; AIN-76A plus 20% olive oil, Group MONO. After 29 days, the rats were tested for irritability toward handling, open-field activity, passive-avoidance learning on a modified apparatus, and visual discrimination learning with reversal. The rats in Group POLY had lower total-cholesterol-to-HDL- cholesterol ratios than did animals in any other group. Except for shorter latencies by Group MONO rats to leave the platform on the passive-avoidance training trials, no behavioral differences were observed. |
