Bet You Can't Eat Just One: Testing the Abuse Liability of Hyper-palatable Foods
The study will conduct a laboratory study designed to evaluate the rewarding and addictive properties of hyper-palatable foods (HPF), using potato chips as the food stimulus/sample HPF.

Detailní popis
A within-subjects, double-blind, randomized crossover design will be used to test the abuse liability of a commonly consumed hyper-palatable food (HPF; potato chips) in controlled laboratory conditions, compared to a negative (non-HPF) control and modified doses (Aim 1).
In alignment with FDA requirements, the study will randomize participants to complete four study sessions in one of four mixed orders to counterbalance the ordering of food stimuli across participants.
One food will be assessed per session.
Abuse liability tests will consist of an acute dose effects comparison to evaluate differences in acute rewarding effects, and a test of HPF reinforcing effects via a self-administration task and behavioral economic food purchase task.
Participants will be community members who report high dietary intake of potato chips (HPF stimulus in the study), and do not have substance use disorder or eating disorders, which may present confounds.

Jiný: Sequence 1: Full Dose HPF → Modified Dose- No Fat → Modified Dose No Sodium → Negative Control
Participants receive Full Dose HPF chip at Visit 1, Modified Dose- No Fat chip at Visit 2, Modified Dose- No Sodium chip at Visit 3, and Negative Control chip at Visit 4.

This food stimulus is a regular, fried potato chip (with no modifications), considered the full dose hyper-palatable food stimulus. The nutrient characteristics are as followed (per 7 grams): 40kcal calories, 2.5g fat, 35mg sodium, 3.8g carbs.
The food stimulus is a baked/"air fried" potato chip with sodium.
Thus, the stimulus will have almost no fat.
The nutrient characteristics are as followed (per 7 grams): 34kcal calories, 0.9g fat, 37mg sodium, 4.0g carbs.
The food stimulus will be a fried potato chip, unsalted.
The nutrient characteristics are as followed (per 7 grams): 38kcal calories, 2.5g fat, 0.6mg sodium, 3.8g carbs
The food stimulus is a baked/"air fried" Jicama root vegetable chip which will serve as the negative control with no sodium, fat, and lower carbohydrates.
The nutrient characteristics are as followed (per 7 grams): 20kcal calories, 0g fat, 0.1g sodium, 0.7g carbs.

Jiný: Sequence 2: Modified Dose- No Fat → Modified Dose- No Sodium → Negative Control → Full Dose HPF
Participants receive Modified Dose- No Fat chip at Visit 1, Modified Dose- No Sodium chip at Visit 2, Negative Control chip at Visit 3, and Full Dose HPF chip at Visit 4.
