| Study group | Role | What they receive |
|---|---|---|
| Potato form 1 | Experimental | The potato served within the vegetable dish will be oil fried. Receives: Other: vegetable combination 1; Other: vegetable combination 2; Other: vegetable combination 3; Other: vegetable combination 4; Other: vegetable combination 5 |
| Potato form 2 | Experimental | The form of the potato within the vegetable dish will be air fired. Receives: Other: vegetable combination 1; Other: vegetable combination 2; Other: vegetable combination 3; Other: vegetable combination 4; Other: vegetable combination 5 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in liking of non-starchy vegetables served within the plant forward meal
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.
Measured: Baseline and after each meal condition (approximately 5 weeks)
Differences in total non-starchy vegetable intake between meal conditions
Gram intake of non-starchy vegetable intake at each meal
Measured: Baseline and after each meal condition (approximately 5 weeks)
Secondary outcomes (1)
Adolescent and young adult (18-25 years) knowledge and attitudes of potato nutrition and preparation
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. Scores will be reported as two subscales -1) knowledge and 2) attitudes with higher scores equating to greater knowledge and more positive attitudes respectively.
Measured: After final 5th meal (approximately 5 weeks)
