Acquired sensory preferences for protein in diabetic and normal rats

Rats made diabetic by injection of streptozotocin, either after adaptation to a cafeteria or some weeks beforehand, increased their intake of protein relative to that of other macronutrients. Preference for an arbitrary odor added to the protein was increased. Normal rats were repeatedly given brief access to either protein-free or protein-containing diet while maintenance chow was withheld for 10 h. They came to prefer the odor-taste combination included in the protein diet to the flavor included in the protein-free diet. It is suggested that, not only in diabetic and protein-deprived rats, but also in normal rats not long since the end of amino acid absorption, the supply of amino acids establishes a relative conditioned attraction for associated food flavors.
