Ever feel like health news is too overwhelming, fast-paced, or hard to decipher? Us too. Here, we filter through the latest in integrative health, wellness trends, and nutrition advice, reporting on the most exciting and meaningful breakthroughs. We’ll tell you exactly what you need to know—and how it might help you become a healthier and happier human.

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.

Considering that research shows that couples share skin microbiomes, this finding isn't too far-fetched—but if you're craving some individuality, you can always try giving your taste buds a reset.
