If your date’s preference for well-done steaks or an aversion to anchovies is a deal breaker for you, you may want to reconsider. A recent study shows that couples begin to develop similar smell and taste preferences if they stay together long enough. The research was conducted by researchers from Poland and Germany. The team studied 100 couples ages 18 to 68 who had been together for 3 months to 45 years. They predicted that the pairs who had been in relationships the longest would share the closest tastes, not unlike how some long-term couples grow to resemble each other in personality and even appearance over time.
What they found is that a couple’s smell and taste preferences do in fact start to align more closely the longer they’ve been together. This is especially true with taste. The study authors write that this is probably the product of a shared environment. If a couple lives in a neighborhood that smells like grass, or if they drink coffee together every morning, they may grow to like those stimuli more than they did at the start of the relationship.
