Our brains course of tastes earlier than factoring in well being info, finds new examine
Our brains course of style info first, earlier than factoring in well being info, in line with a brand new analysis from Duke University.
The findings of the examine had been revealed within the journal ‘Nature Human Behaviour’.
“We spend billions of dollars every year on diet products, yet most people fail when they attempt to diet,” mentioned examine co-author Scott Huettel, a professor of psychology and neuroscience at Duke.
Here’s what the examine has to say
Huettel added, “Taste seems to have an advantage that sets us up for failure. For many individuals, health information enters the decision process too late (relative to taste information) to drive choices toward the healthier option.”
The new paper described the benefit style has over healthfulness within the decision-making course of.
“We’ve always assumed people make unhealthy choices because that’s their preference or because they aren’t good at self-control,” mentioned examine co-author Nicolette Sullivan.
“It turns out it’s not just a matter of self-control. Health is slower for your brain to estimate – it takes longer for you to include that information into the process of choosing between options,” added Sullivan.
The analysis was undertaken when Sullivan was a postdoctoral affiliate at Duke. She is now an assistant professor of selling on the London School of Economics and Political Science.
For the examine, Sullivan and Huettel recruited 79 younger adults of a median age of 24.4 years. Study individuals had been requested to quick for 4 hours earlier than the experiment to make sure they arrived hungry.
Participants had been requested to rate snack meals on their tastiness, healthfulness and desirability. They had been then introduced with pairs of meals and requested to decide on between them – and the researchers timed their choices.
At the tip of the experiment, individuals had been supplied one of many meals that they had chosen.
Study individuals registered style info early of their resolution course of – taking about 400 milliseconds on common to include style info. Participants took twice as lengthy to include details about a snack’s healthfulness into their selections.
That might not sound like a lot time. In many instances although, it’s sufficient to change the selection we make.

“Not every decision is made quickly – house purchases, going to college – people take time to make those choices,” Huettel mentioned.
“But many decisions we make in the world are fast – people reach for something in the grocery store or click on something online,” Huettel added.
The authors mentioned their findings may apply to different choices, and never simply food. For occasion, some monetary selections, corresponding to saving and spending choices, can also be affected by how – and when – the brain processes several types of info. Meanwhile, all will not be lost within the conflict towards junk food cravings.
Half of the examine individuals acquired a blurb earlier than the experiment, stressing the significance of maintaining a healthy diet. Those individuals had been much less doubtless to decide on an unhealthy snack.
The authors additionally recognized one thing easy that may assist individuals with their food choices: slowing down the decision-making course of. When examine individuals took longer to contemplate their choices, they tended to select more healthy ones.
“There may be ways to set up environments so people have an easier time making healthy choices,” Huettel mentioned.
“You want to make it easy for people to think about the healthfulness of foods, which would help nudge people toward better decisions,” Huettel concluded.
