But reliably producing and describing F-N conditioning effects with human participants in controlled studies has been challenging, and some studies fail to detect effects. There are a number of reasons this may be. First, people already have extensive exposure to different foods and established likes and dislikes for flavors. Conditioning is likely to be much less effective with familiar flavors. It is also theoretically debatable whether “liking” should be the main dependent variable, since animal experiments sometimes find effects on choice and intake without liking.

Animal studies that can carefully monitor the development of sweet and fat responses show that they differ in several important respects. First, fat palatability emerges much later in the pre-weaning period53,57,58 and increases with maturation, unlike sweet-liking, which is initially high. 59,60 Also, the shape of the concentration-response function differs substantially from that for sugars. In sham-feeding studies of oral reward, intake of sweet solutions increases monotonically as a function of concentration.
