- In adults, fat is a major determinant of food palatability. From the onset of complementary feeding (CF) adding fat to complementary foods is recommended to ensure an optimal growth and cognitive development. However, whether adding fat to complementary foods would impact acceptance (in terms of intake and liking) has been little investigated. This study sought 1) to evaluate acceptance of added fat (either vegetable oils or dairy fat) in a vegetable puree in weaning-age infants; 2) to determine whether early differential fat exposure through milk (breast milk and formula have different fat composition) and fat addition in complementary foods can influence acceptance and 3) to explore if fat acceptance can be related to inter-individual differences in salivary compounds potentially involved in fat perception.Twenty six infants with contrasted milk feeding history participated and were introduced with complementary foods at 4.8 months. During the 1st month of complementary feeding, acceptance of 3 broccoli purees (0% fat, 7% of vegetable oils, 7% of dairy fat) was determined through ad libitum intake and global liking, in the laboratory and at home. Saliva was collected: lipolytic activity and carbonic anhydrase 6 concentration were determined.Puree intakes were not impacted by fat addition, whatever the type of added fat. Moreover, the history of milk feeding (breast milk vs. vegetable oils based formulas) in the very first months did not explain acceptance for added fat. Finally, no links between intake and saliva composition were evidenced. Altogether, this study found that the addition of fat did not modify food acceptance by infants during early complementary feeding. Thus, future research should investigate the development of fat acceptance over experience in early infancy.
