How long have you been with your partner? A few months? Thirty-five years? The answer to that question may indicate how similar your taste buds are. Yep, you read that right: According to new research published in the journal Appetite, couples develop similar scent preferences and food tastes when they've been together for a while.
For the study, researchers had 100 couples who had been together for different periods of time—this time frame spanned between three months and 45 years—rate different scents, such as smoked meat, leather, rose, and eucalyptus. The couples were then asked what they thought of a series of flavors, such as sweet, salty, sour, umami, and bitter when they were sprayed on their tongues.
Interestingly, the longer they had been together, the more similar their taste buds were—even if they weren't all that happy in their partnership. While researchers don't know exactly why this is, they think it could come down to a number of factors. Perhaps people are more compatible when they smell the world similarly, or it could have to do with environmental exposure.
"Shared environment and habits, and consequently exposure to similar olfactory and gustatory stimuli, might together shape similar preferences in both partners," write the researchers.
