Participants will not receive the priming manipulation.

Participants will be cueing with health benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have health benefits, such as..."

Participants will be cueing with environmental benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have environmental benefits, such as..."

Participants will be cueing with environmental and health co-benefits by asking to do a word-search exercise beginning with: "In the following, please choose words/statements that can indicate that having a healthy and sustainable diet can have both benefits for health and the environment, such as..."

The priming manipulation will be embedded in one discrete choice experiment to test the effect of three priming interventions: priming with health benefits, environment benefits, and co-benefits of having sustainable diets, respectively, on consumers' preference for sustainable foods, and the relative importance of proximal attributes (e.g. taste and price) and distant attributes (e.g., attributes related to environmental sustainability) in determining food choice preference, as well as testing whether the effects of these three priming interventions can be modified by consumers' social orientation values. The cueing manipulation will be achieved by asking participants to complete a word-search exercise.

• Measure name: consumers' food consumption preference
• Measure tool: an online discrete choice experiment
• Measure units: The frequency of choosing sustainable food

• Measure name: Social Orientation Value (SVO)
• Measure tool: survey questionnaire
• Measure units: subjects can slide along a continuum of own-other payoff allocations, measure units should be the times participants choose own or self.
