Food Psychology: The three drivers of eating

Do you sit down to watch a movie and wonder why you just can’t seem to stop eating? There may be a very good reason why. In nutrition psychology, there are three potential drivers for the food choices that we make. These are:

1. Palatability: eating to satisfy the want for a certain food sensation (reaching for a particular taste, or texture). For example, this can be in response to a psychological or physical need (such as reaching for comfort foods as a response to stress). It is also interesting to know, humans are naturally more drawn to more sweet tasting foods and reject more bitter foods – these are the only taste preferences we are born with, all of our other preferences are learned!

2.  Physiology: eating to satisfy a physiological need (eg. hunger, energy availability, macronutrient requirement). One very common example of this is finishing a busy work day just to come home and eat everything in the kitchen – reaching for a snack then all of a sudden the whole bag of potato chips is gone. The biggest cause of this behaviour is undereating during the earlier parts of the day (putting the body in a negative energy balance), therefore driving you to reach for more energy dense food choices.

3. Preoccupation: eating food associated with a task or action (eating while watching TV). This eating behaviour is not associated with fulfilling a psychological or physiological need – it is an example of a task-related behaviour. The human brain is not a great multitasker and therefore, can only actively pay attention to completing one task at a time. While we are performing a non-food related task, we are less in-tune with the body’s hunger cues and are more prone to overeating.
