Brief Summary:
The purpose of the research is to examine the association between price changes, nutrient profiling, and grocery food purchases among household grocery shoppers.

Condition or disease Intervention/treatment Phase
Nutrition Food Purchases Behavioral: Nutrient profiling Behavioral: Price Changes Not Applicable

Detailed Description:
Participants will be asked to select a week's worth of groceries for their household from a virtual online grocery store. Shoppers will be randomly assigned to one of four conditions (control, nutrient profiling, price change, nutrient profiling and price change).

Primary Outcome Measures :
  1. Nutritional Quality of Food Purchases [ Time Frame: Participants were followed for one shopping session, an average of 2.5 hours ]
    The Overall Nutrient Quality Index (ONQI) was used to assess nutritional quality of foods purchased. The ONQI is a 1 - 100 scale in which higher numbers indicate higher nutritional quality. Each food is given a score based on a ratio with positive health nutrients in the numerator and detrimental health nutrients in the denominator, based on a proprietary algorithm created by NuVal. The average ONQI score for all the groceries purchases was used as the outcome measure, of ONQI scores on a scale.
