STUDY: Food Taste Change According to Our Relationship Status

People in Relationships Taste Food Differently

When you’re in a relationship, especially long-term, a lot of things change. Single life is slowly replaced by habits that you and your significant other make together. That being said, a relationship has a deeper impact on an individual than previously thought.

The impact of dating or being in a relationship goes so far to change the way you taste the food you eat. Seriously! The latest study made this interesting discovery and this post brings you all the details.

Relationships and Taste Preferences

Previous research has already confirmed the existence of partners’ harmony in different domains of relationship life. As the time goes by, the compatibility between two people increases* even more.

While different studies explored this subject, none of them addressed the shift in chemosensory perception in relation to relationship length. Chemosensory perception is defined as the perception of chemical signals by the senses, especially taste and smell.

In order to get an insight into this interesting subject, Agata Groyecka and a team of scientists at the University of Wroclaw from Poland carried out a study.

The primary objective of the research was to examine the relationship between the time heterosexual couples spent together and the degree to which they share olfactory (sense of smell) and gustatory (sense of taste) preferences.
Also, scientists wanted to inspect whether the preferences have anything to do with relationship satisfaction.

How Do Taste Preferences Change In Relationship?

Scientists enrolled 100 couples aged between 18 and 68. The length of relationships also varied from 3 to 540 months (45 years). All couples were asked to rate the pleasantness of different gustatory and olfactory stimuli.

Results of the study, published in the January 2018 issue of journal Appetite[1], confirmed that the way we taste food changes in the relationship. In fact, the longer two people are in a relationship, the more their taste and smell preferences become similar.

Scientists also made yet another discovery showing that relationship satisfaction is closely related to smell preferences. Greater relationship satisfaction was strongly related to bigger smell congruence and vice versa.

Smell and Taste Preferences

Although the study confirmed out smell and taste preferences change in relationships, the reason behind this phenomenon is unknown.

It could be down to the fact that two people become more alike when they spend time together. For example, when couples share meals or live together, they are more likely to eat similar foods.

Scientists explain[2] that shared environment, habits, and exposure to similar taste and smell stimuli, might shape our preferences. As a result, we experience these changes when we’re in a relationship.

Of course, there are some potential biological reasons too. For example, some previous studies found that smell may play a role in evolutionary purpose. The more similarly partners smell the world, the more compatible they get.

Other reasons include the fact that people usually date someone who shares the same interests and preferences. That way, it would be easy to explain why some couples have similar preferences regarding taste and smell.

Researchers who worked on this study call for further research on this topic in order to explore mating mechanisms linking partners’ congruence in odor preferences and relationship satisfaction.

Also, carrying out more studies would help discover underlying mechanisms associated with taste preferences.

When two people spend a lot of time together they become more compatible. A growing body of evidence confirms the compatibility idea, but none of them took into account senses like smell and taste.

A team of scientists from Poland carried out a study which discovered that couples change taste and smell preferences. The discovery calls for more research on this topic.
