Abstract
Dietary saturated fatty acids (SFAs) mediate behaviour, in the absence of nutrient deficiency, beyond brain development, and at fat levels consistent with North American consumption. The present experiments examined the influence of SFA chain length on macronutrient selection and the roles of glucose and insulin in mediating this feeding behaviour. Rats fed medium-chain triglyceride oil selected more protein and less carbohydrate than rats fed three other fats (hydrogenated coconut oil, fully hydrogenated soybean oil (HSB), and soybean oil). HSB-fed rats selected differently from previously reported long-chain SFA-fed animals, however, HSB was insufficiently absorbed. Although glucose and insulin concentration did not differ among diet groups, measures of insulin sensitivity correlated with selection. These results suggest that SFA chain length may influence macronutrient selection, but the specific relationship between chain length and selection remains undefined. A decrease in insulin sensitivity leads to an increase in protein and a decrease in carbohydrate intake.
