Abstract

We investigated the effect of food appearance on appetite and on left-frontal pole blood flow in healthy young subjects. The iEat, a new form of foods with good appearance and greater softness was hypothesized to have the better effects to the subjects than blender-processed foods. The effect on appetite and left-frontal pole blood flow using hemoencephalography was assessed while participants were viewing the slideshows of two kinds of foods respectively. The slideshows were used to control the showing time and other variables. The pictures of iEat foods stimulated both of them more than the blender-processed ones. The measurement of cerebral blood flow could be a useful method to monitor the cognitive and emotional aspects of feeding behavior that are important for humans. Like iEat, the foods that look as good as ordinary food yet are softer can be used for people with poor appetite and eating difficulties to ordinary food.
