Why do our taste preferences change as we age?
Why do our tastes change as we get older? Thanks for asking. Think back to when you were a kid and there was a type of vegetable you simply wouldn't go near, let alone eat. It might have been broccoli, Brussels sprouts or spinach, for example. Or perhaps another type of food like seafood, which now as an adult you actually quite like, or can tolerate at least. It's not a coincidence.
There are scientific explanations for why our taste preferences evolve with time.
What tastes do children actually like most then?
sweet and salty in particular, and it's possible that this is due to evolution. In concrete terms, human history has led us to be wary of bitter tastes, and to seek out sweet tastes instead.
That's because sugary foods are seen as attractive for their energy content, whereas bitterness is linked to substances found in toxic products, hence the negative association, and our inclination to avoid it at an early age. Another explanation is that children live in different sensory worlds.
To use the words of biopsychologist Julia Minella, as quoted by Discover magazine in March 2022, a lot of researchers think that children have a hypersensitive sense of taste. No doubt the fact that young children start out with 10,000 taste buds has something to do with it, a number which halves by the time we reach adulthood.
Does this hypersensitivity decrease with age then?
Indeed it does, and that process starts as early as in our teenage years. Our sensitivity to bitterness diminishes, we have less of a preference for sweet and salty foods, and our tastes become more complex as our senses of taste and smell evolve. Our brain starts perceiving flavours differently as we develop our taste experiences.
Taste buds are located on the tongue, palate, oesophagus and at the back of the throat. They respond to five different basic tastes. Sweet, salty, sour, bitter and umami. If you've not heard of umami, then take note. It means savory and was identified in 1908 by Japanese researcher Kikuna Ikeda. Umami foods include onions, mushrooms, raw ham, and fermented foods.
