A brand new examine from the University of Kansas within the journal Appetite examines folks’s decisions when confronted with an all-you-can-eat buffet.
It seems that the food we select to heap on our plates may predict our possibilities of having greater weight achieve or weight problems. The researchers centered on meals outlined as “hyperpalatable” — dividing this class into carbohydrate and sodium (CSOD) meals or fats and sodium (FSOD) meals — and in contrast them with high-energy dense and ultra-processed meals.
“Hyperpalatable foods have combinations of ingredients that can enhance a food’s palatability and make a food’s rewarding properties artificially strong,” stated lead writer Tera Fazzino, assistant professor of psychology at KU and assistant director of the Cofrin Logan Center for Addiction Research and Treatment at the KU Life Span Institute. “Common examples would be various chocolates, hot dogs, pretzels or brownies — foods that can be difficult to stop eating.”
In the examine, youthful adults with out weight problems ate a meal at an all-you-can-eat buffet. The analysis crew measured their body composition earlier than the meal and adopted up a 12 months later. The examine tracked associations between proportions of buffet gadgets chosen by members — high-energy density meals, ultra-processed meals and hyperpalatable meals — and members’ weight change and % body fats change one 12 months later.
“We were able to look at their behavioral tendency to consume certain types of foods,” Fazzino stated. “Is that associated with greater energy intake relative to their physiological energy needs, and is it longitudinally associated with weight and percent body fat gain?”
Fazzino’s co-authors had been James Dorling, John Apolzan and Corby Martin of the Pennington Biomedical Research Center, Louisiana State University System. They shared the dataset that was analyzed for this examine and collaborated on the article.
Fazzino and her colleagues discovered members who consumed a larger proportion of hyperpalatable carbohydrate and sodium (CSOD) meals of their buffet meals had considerably larger weight change and % body fats change at the evaluation a 12 months later.
“A couple of classic examples of hyperpalatable CSOD foods would be pretzels or popcorn,” Fazzino stated.
But the examine additionally discovered no vital body modifications a 12 months later for these within the buffet examine who ate high proportions of fats and sodium hyperpalatable meals, high-energy dense and ultra-processed meals.
The researchers concluded eating extra hyperpalatable carbohydrate and sodium meals at an all-you-can-eat buffet might point out a bent towards “hedonic eating,” which can enhance a person’s danger for weight and body-fat achieve in early maturity.
“‘Hedonic eating’ is a general term that’s used in the literature to refer to eating that’s more focused on the rewarding characteristics of a food, as opposed to strictly satisfying physiological hunger,” Fazzino stated. “The take-home point is really that people who tended to consume more carbohydrate and sodium foods — when they were freely available — were at greater risk for weight and body fat gain.”
However, some folks don’t have a alternative in eating hyperpalatable meals.
Fazzino’s new paper builds on analysis she co-wrote earlier this 12 months in Frontiers in Psychology meant to uncover how a lot infants are uncovered to meals deemed hyperpalatable.
“If we think about how these foods can activate the brain-reward neural circuitry in a similar manner as some drugs of abuse, we want to look at the earliest point of exposure,” Fazzino stated. “When babies start to eat tablelike solid foods — that’s what we were interested in. We wanted to know the earliest exposure point possible for these foods and the exposure rate among infants. Also, we wanted to characterize the prevalence of these types of foods in baby foods that are available in the U.S. food system.”

The researchers discovered an astounding 90% of 147 infants within the examine had been fed hyperpalatable meals, primarily as a result of they’re being fed grownup meals frequently. Moreover, 12% of meals marketed as “baby food” had been discovered to be hyperpalatable within the examine.
“We found when babies are starting to eat the adult foods, that’s the primary vehicle for their exposure,” Fazzino stated. “We did characterize their overall caloric intake. For infants under 12 months, they consumed on average 38% of their daily food calories from hyperpalatable foods, and for older infants it was 52%.”
Because the prevalence of hyperpalatable meals amongst U.S.-produced baby food is comparatively low, Fazzino cautioned dad and mom ought to focus their attention on the grownup meals supplied to infants to head off probably dangerous eating habits that might take root in infants as they age.
“If babies are consuming foods that are artificially highly rewarding at early in infancy, this could essentially indicate to their system physiologically — and to their brain — that, ‘Hey, this is what food is supposed to taste like, and this is how rewarding it’s supposed to be.’ Our concern is they’ll get used to this level of really intense taste and intense reward at an initial point, which will then make them want to consume those types of foods more as they grow up. Ultimately, the worry is that maybe this is an early predisposing factor for obesity risk.”
