This is Scientific Americans' 60-second science. I'm Erica Barris. Got a minute?

In Marcel Proust's iconic remembrance of things past, a taste of cake elicits a flood of memories.

Now a study finds that the stronger your memory of a particular food, the more likely you are to

choose it again. And it doesn't matter how objectively

unattractive the food may be, which perhaps explains why you may crave those peanut butter and

marshmallow sandwiches from your youth or can't break that fried chicken habit when trying to diet.

The food memory study is in the journal Neuron. Researchers asked 30 hungry young people to rate snacks such as potato

chips and chocolate. No actual food was presented. The snacks were merely displayed on screens

associated with locations. Then the study participants were asked to choose between two locations,

as proxies for the snacks. And the hungry subjects went with memory over taste preference.

That is, they picked what they were better able to remember, even if they had rated them

lower in the first part of the test.

The participants' brains were scanned during the process of choosing, and the researchers

found that the exercise caused increased communication between the hippocampus associated with memory and the part of the frontal lobe home to decision making, which may show why when we're making food decisions, familiarity often went out over other factors, and why your shopping list looks virtually the same week after week.

Thanks for the minute.
