5 Reasons Why We Crave Comfort Foods

The attraction of comfort food

Posted Sep 28, 2016

Comfort foods are typically energy-dense, high fat and sweet, such as chocolate, ice cream, and French fries. They give distinctive pleasure or make us temporarily feel better. The followings describe 5 factors that can contribute to comfort eating.

1. Feel good. Eating food high in fat, sugar or salt activates the brain’s reward system. For example, chocolate has a strong effect on mood, generally increasing pleasant feelings and reducing tension. Highly palatable foods activate the same brain regions of reward and pleasure that are active in drug addiction. Studies of obese individuals show that brain areas associated with drug reward are activated by anticipation and receipt of highly palatable foods (Avena et al., 2012).

2. Comfort food as self-medication. There seems to be a consistent connection between negative emotions and unhealthy foods. A phenomenon called emotional eating. In a bad mood, people are drawn to unhealthy foods (eating sugary and fatty) as a coping mechanism. In contrast, people in a positive mood tend to choose healthy foods (Gardner et al., 2014). However, a study (Mann, 2015) found that although the comfort foods provided some relief from negative moods, but so did the other foods and even receiving no foods at all. Furthermore, comfort foods can put you in bad a mood (Hendy, 2012). In fact, the link between consumption of comfort foods and increased negative moods (due to perhaps crash after a high-carb meal or guilt) lasted over a period of two days.

3. The need to belong. We tend to associate certain foods with members of our family, social gatherings, and people taking care of us (Thanksgiving holidays with family).  So when we feel lonely we crave for these foods to give us comfort and security. That is, comfort food’s power may lie primarily in the associations it calls to mind (memories of secure attachment). For example, for a college student away from home for a first time, comfort foods may serve as a reminder of family or other relational in times of stress or isolation. Evidence showed that people with positive family relationships were more likely than others to reach for comforting foods on the days that they felt lonely (Jordan et a., 2015).

4. Nostalgic eating. There is a strong link between scents and emotional memory. Smell of foods can evoke vivid and detailed emotional memories of our past (Reid, et al., 2014). Our learning history predisposes us to enjoy certain foods. For example, the scent of something deep-fried corn dogs may remind one’s childhood at the state fair during summers. Because odor-evoked memories tend to be positive, the smell improves the mood and produces feelings of social connectedness. 

5. Special occasion. We tend to go for special, often unhealthy, foods on celebratory occasions, like birthdays or Thanksgiving. The excuse reflects an underlying dilemma. From a momentary perspective, the indulgence is the best choice; but from a long-term perspective, healthy eating is the best choice. The ideal solution is to somehow do both. This is impossible, except in one situation. If the situation can be framed as the “last time,” then the dilemma disappears, since the person can say to herself that a new and better life will begin tomorrow.
