Diabetes and a high-fat/low-carbohydrate diet enhance the acceptability of oil emulsions to rats.
Acceptability of corn oil and coconut oil emulsions was examined in streptozotocin-diabetic (55 mg/kg, IP) and normal rats fed either a high-fat/low-carbohydrate (HF/LC) or low-fat/high-carbohydrate (LF/HC) diet. Intake of five concentrations of the emulsions (2.5, 5, 10, 20 and 40%) was measured in 30-min, one bottle intake tests. Diabetic rats consumed more of the oil emulsions than did normal rats. Emulsion intake by diabetic rats increased, then decreased across concentrations, whereas emulsion intake by normal rats showed little change across concentrations. No differences in the intake of corn and coconut oil emulsions were observed. Total oil consumption was higher in diabetic than in normal rats at the three highest emulsion concentrations. Total oil consumption was also higher in rats fed the HF/LC diet as compared to those fed the LF/HC diet. These findings suggest that the presence of diabetes or feeding a HF/LC diet can enhance oil emulsion intake of rats in short-term tests.
