If you aren't aware, I study nutrition and dietetics. I'm at a children's hospital for the summer, and recently, I had the opportunity to observe a few feeding evaluations - what are they?
If you've watched a cop show or are familiar with marketing, you might know of one-way mirrored observation rooms (you know, during interrogation or focus group scenes). The same room is used in a feeding evaluation, where the patient being observed is in the room, exposed to foods they like and foods they may have issues with. With a pediatric population, parents tend to be in the room with them, while the clinicians stand behind the glass window and watch how the patient reacts to the foods. Do they eat it? What faces are they making? Is the food visually overwhelming? Is there a common characteristic across the foods avoided? Does the patient have an aversion to texture?
