Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in liking of non-starchy vegetables served within the plant forward meal | Baseline and after each meal condition (approximately 5 weeks) | Ranking of degree of liking for each vegetable served within the plat forward meal on a scale of 1-100 on a visual analog scale where 1= extremely dislike to 100= Extremely like. Measured at baseline, within a taste test before each meal, and after each meal. |
| Differences in total non-starchy vegetable intake between meal conditions | Baseline and after each meal condition (approximately 5 weeks) | Gram intake of non-starchy vegetable intake at each meal |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Adolescent and young adult (18-25 years) knowledge and attitudes of potato nutrition and preparation | After final 5th meal (approximately 5 weeks) | A series of 10 questions related to nutrient content and health attitude statements where participants rate their agreement on a 1-100 point visual analog scale where 1 = extremely disagree and 100 is extremely agree.
