Since I am a vegetarian I have a hard time understanding people not liking veggies (except for mushrooms which I have talked about before and only recently been able to tolerate). So when I read the below article I finally understood how this could happen. I hope you find it as interesting as I did.
This has to do with more than just your taste buds (which are there to taste, yes, but not to dictate whether or not you like something). Just FYI: Your sense of smell plays a role in taste too, by helping determine the flavor, which, unlike taste, is "a multi-sensory construct that our brain 'composes' from multiple sensations, namely taste, smell, sound," explains Hopfer.
While everyone has a similar sensitivity to the various basic tastes, you develop personal preferences over many years, depending on other factors like habits, upbringing, culture, memories, and context, says Dando. You may have grown to hate salmon for example, because you got the stomach bug after eating it once, so now you associate it with nausea (bleh).
All of those factors can also play into why you might hate Brussels sprouts, while your sister loves them-because your experiences with the food differ. But that doesn't mean you'll hate certain foods forever, either. You can actually retrain your brain to like certain tastes by eating them more frequently. And just as you can acclimate your tastes to like something new (or re-like something old), you can also change them to start disliking something. Take sugar, for example: "I recently tried to cut out soda from my diet and after a short time I found just a sip to be sickly sweet," says Dando.
Honestly, a lot is still unknown about why you might've hated something like tomatoes up until, say, a year or two ago. It could be as simple as experiencing a certain type of food in a new way (like, roasted broccoli instead of steamed), says Hopfer. Or, frustratingly enough, "the brain can also change its mind," she says, adding that your mind and perceptions (taste, smell) are constantly undergoing changes throughout your life.
The bottom line: Your taste buds regenerate every couple of weeks-but your ever-changing mind and personal experiences have more to do with why you might start to like or dislike a new food.
