The range of classifications given to food images in this review such as “high” and “low” calorie foods and “palatable” and “bland” foods appears subjective and arbitrary, with no studies consulting a dietitian or nutritionist. Only seven studies specifically identified actual calorific values of foods and the majority of studies did not pilot test images or provide rationale for their selection of presented foods. The selection of foods in research studies is important to ascertain if it is a universal chemical component of food (e.g., selection based sugar or fat content), a whole category of food (e.g., selection of ‘junk food’), or more simply a personal preference (e.g., selection by administering a pre-scan survey) that could make a food more likely to be overeaten. This could provide further insight into whether food addiction is a plausible phenomenon. Furthermore, the range of control images presented were variable and included cars, landscapes, and blurred images. As these images were not standardized across studies, it is unknown as to whether these assorted images may elicit different neural patterns from one another based on their perceived valence and arousal. The variability of food images used in studies has been previously acknowledged and a database of standardized pictures based on image characteristics and nutrient composition has recently been developed (105). Future studies should consider the use of such a database to facilitate the standardization of images and comparability across studies.","tracks":[{"project":"0_colil","denotations":[{"id":"25988110-22319604-908729","span":{"begin":265,"end":267},"obj":"22319604"},{"id":"25988110-17714197-908730","span":{"begin":269,"end":271},"obj":"17714197"},{"id":"25988110-16762940-908731","span":{"begin":273,"end":276},"obj":"16762940"},{"id":"25988110-25009514-908732","span":{"begin":1677,"end":1680},"obj":"25009514"}],"attributes":[{"subj":"25988110-22319604-908729","pred":"source","obj":"0_colil"},{"subj":"25988110-17714197-908730","pred":"source","obj":"0_colil"},{"subj":"25988110-16762940-908731","pred":"source","obj":"0_colil"},{"subj":"25988110-25009514-908732","pred":"source","obj":"0_colil"}]},{"project":"2_test","denotations":[{"id":"25988110-22319604-38724656","span":{"begin":265,"end":267},"obj":"22319604"},{"id":"25988110-17714197-38724657","span":{"begin":269,"end":271},"obj":"17714197"},{"id":"25988110-16762940-38724658","span":{"begin":273,"end":276},"obj":"16762940"},{"id":"25988110-25009514-38724659","span":{"begin":1677,"end":1680},"obj":"25009514"}],"attributes":[{"subj":"25988110-22319604-38724656","pred":"source","obj":"2_test"},{"subj":"25988110-17714197-38724657","pred":"source","obj":"2_test"},{"subj":"25988110-16762940-38724658","pred":"source","obj":"2_test"},{"subj":"25988110-25009514-38724659","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"0_colil","color":"#eceb93","default":true},{"id":"2_test","color":"#d193ec"}]}]}}
