Adherence
Using taste-focused labels (emphasizing specific flavors and positive experiences) on vegetable dishes significantly increases vegetable selection and consumption compared to health-focused or basic labels.
When labeling healthy food, especially vegetables, describe the specific flavors, ingredients, and preparation methods (e.g., 'Roasted Garlic Broccoli') rather than just listing health benefits (e.g., 'High in Vitamin C'). This approach leverages the natural human preference for taste, making healthy choices more appealing and increasing the likelihood that people will select and consume them.
Across 137,842 diner decisions, 185 days, and 24 vegetable types, taste-focused labels increased vegetable selection by 29% compared with health-focused labels and by 14% compared with basic labels. Vegetable consumption also increased.
