Couples Who Are Together Longer Start To Develop The Same Preference For Taste


When it comes to food preferences, we all have our own likes and dislikes. When a couple marry, chances are they may not agree entirely on their food choices. However, all this can change the longer their marriage.

A study has shown that couples who are married for a longer time, develop a similar sense of taste and smell.


The study, from the University of Wroclaw, is the first of its kind to show that the longer couples have been together, the more similar their tastebuds become.

From years of shared meals and adapting to new tastes and flavors, couples begin to change their food preferences from just eating together.

Sharing their discoveries in the journal Appetite, the Polish researchers express:

“As partners share a household (including a kitchen and fridge) and a significant proportion of meals, they are more likely to eat similar types of food. Even though the role of genetics in accounting for individual differences in food preferences is well documented, shared environment and habits, and consequently exposure to similar olfactory and gustatory stimuli, might together shape similar preferences in both partners.”


The study tested couples who had been married from three months to 45 years, a total of 100 men and 100 women.

The couples were tested on their preferences for various smells, including lavender, white chocolate, coffee, cinnamon, smoked meat, coca cola, lemon and honey, to which both partners were asked to inhale for five seconds.

The subjects were then asked to rate these smells from one to five, from being liked a lot to not at all. The men and women then had sweet, sour, salty, and bitter flavors sprayed into their mouths, again, rating them on the same scale of like and dislike.

The end result from the study on food and taste showed that it was more similar in husbands and wives the longer they had been together.

The length of their marriage made up for nine per cent of the difference in their appreciation in flavor, and six per cent for smells.


The authors, led by Agata Groyecka, wrote:

“Dining customs seem to be an important part of the romantic partners’ daily routine and therefore form a substantial element of their cohabitation. However, dining customs can change over time as partners constantly influence. For example, eating habits and food choices have been shown to shift during the transition from single to cohabiting/married status.”
