Sense Memory

Sense memory is very potent in all animals, including humans, of course. We all recognize this rather quickly when we smell a familiar scent from our childhood or a song reminds us of some experience. Strong sense memories very likely helped our ancestors survive since recalling it was yet another way of seeking food and safety or avoiding danger.

Food is also appealing to us based on sense memory. In fact, one of the reasons we crave foods that we favor is that we wish to repeat or reinforce the sense memory. The only thing that separates a carrot slice from a potato chip in desirability is the time it spends on the tongue. Once you swallow it, your stomach doesn't feel worse or better for being full of chips instead of carrots.

The interesting thing about taste as a sense memory though is that it is one of the least reliable. If you've ever revisited a childhood favorite after a long absence and found it unpalatable, you have had experience with this. The tongue seems to have a short sense memory and is more easily "trained" to appreciate different flavors than other senses are to accept variations. Your nose is unlikely to decide a bad scent eventually smells good through repeated exposure, but people do learn to love foods they used to hate and hate foods they used to love.

What's the point of all of this talk about sense memory? Well, I've been thinking about it and how it can be used to break cravings for certain foods and binging. If you're looking to reinforce a sense memory, how much food must be consumed to give satisfaction, and how best to maximize the experience where it is on the tongue such that consuming more is not necessary? Mindful eating is a part of this, but keeping in mind that your tongue and not your stomach is the part of your body that needs satisfaction might help one feel that less is enough.

I'm also thinking that absence from certain types of food can make the tongue grow far less fond of that food. In my case, I have experienced this rather profoundly with Burger King's original chicken burgers. I used to love them when I was in my early college years, but after not consuming them for a decade or more, find them quite unappetizing upon revisiting one recently.

The purpose of this process is not to "trick" myself into not wanting things I want, but rather in "training" myself to want less of things that are less healthy and eaten for entertainment and to more of those things which are nutritious. My tongue doesn't need to be fooled. It just needs to forget a few old things and gain new memories of better food.
