In modern humans this ability remains intact and is expressed in a selective preference for types of fruit and vegetables that contain more calories. However, humans evolved consuming these low energy-dense foods (typically&nbsp;&lt;&nbsp;1.75&nbsp;kcal\/g) and it remains unclear whether they can also discriminate more energy-dense foods that now feature in modern Western diets. In two experiment participants (both N&nbsp;=&nbsp;40) completed four tasks that assessed the &#039;value&#039; of different sets of 22 foods that ranged in energy density (0.1&nbsp;kcal\/g-5.3&nbsp;kcal\/g and range 0.1&nbsp;kcal\/g to 6.2&nbsp;kcal\/g in Experiment 1 and 2, respectively). In Experiment 1 three measures (expected fullness, calorie estimation, and food choice), and in foods less than approximately 1.5&nbsp;kcal\/g (typically fruits and vegetables), the relationship between perceived value and energy density is linear. Above this, we observed clear compressive functions, indicating relative and progressive undervaluation of higher energy-dense foods. The fourth task (rated liking) failed to provide evidence for any relationship with energy density. In Experiment 2 the same pattern was replicated in measures of expected fullness, and in two different assessments of subjective calorie content. Consistent with the concept of &#039;evolutionary discordance,&#039; this work indicates that modern human physiology is poorly adapted to evaluate foods that have a historically unusual (high) energy density. This has implications both for our understanding of how &#039;modern&#039; energy-dense foods affect choice and energy intake, and for strategies aimed at removing calories from highly energy-rich foods.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-8579","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Nutrition and Behaviour Unit, School of Experimental Psychology, University of Bristol, 12a Priory Road, Bristol, BS8 1TU, UK.
