Veggie temptations
A Stanford University study has found that people were more likely to choose vegetable dishes when they carried indulgent names. For example, ‘twisted citrus-glazed carrots’ were more popular than the same dish labelled simply as ‘carrots’, despite no difference in how they were prepared or served.
Every weekday of the 2016 autumn quarter (46 days), the university canteen served vegetable dishes, prepared and presented in exactly the same way, but labelled in 1 of 4 ways: basic, indulgent, healthy restrictive, or healthy positive (see table 1). The researchers recorded the number of times that the vegetables were chosen, and measured their portion weights.
Basic | Indulgent | Healthy restrictive | Healthy positive |
---|---|---|---|
Carrot | Twisted citrus-glazed carrots | Carrots with sugar-free citrus dressing | Smart-choice vitamin C citrus carrots |
Beets | Dynamite chilli and tangy lime-seasoned beets | Lighter-choice beets with no added sugar | High-antioxidant beets |
Sweet potatoes | Zesty ginger-tumeric sweet potatoes | Cholesterol-free sweet potatoes | Wholesome sweet potato superfood |
Bok Choy and mushrooms | Tangy ginger bok choy and banzai shiitake mushrooms | Low-sodium bok choy and mushrooms | Wholesome bok choy and mushrooms |
Table 1: Examples of labels assigned to vegetable dishes at Stanford University canteen.
The study found that the dishes popularity varied significantly depending on their name. The healthy restrictive ones (e.g. ‘lighter choice’ ‘free from’ ‘low-sodium’) were least popular, while the indulgently named ones were:
- 25% more popular than the basic,
- 41% more popular than the healthy restrictive, and
- 35% more popular than the healthy positive named dishes.
Not only were the indulgently named veggie dishes selected by more people, they were also taken in larger portions.
This study reveals an interesting, low-cost way to encourage healthier choices, and increase vegetable consumption in restaurants and canteens. It also challenges the assumption that highlighting health benefits may boost vegetable consumption. Further research could focus on analysing the effect of indulgent descriptors in different settings, or populations (e.g. children), and could explore the use of indulgent labelling in reversing the common mindset that healthy foods do not taste good.
