Balancing Proportion of Food ‘Vices’ May Be Key to Right Diet
New research finds that it may be OK to eat unhealthy food even when trying to lose or maintain weight. The key is keeping the “bad” food at the right level.
Vanderbilt University researchers call the strategy a balance of “vice-virtue bundles” combining nutritious and not-so-nutritious foods.
“We suggest a simple … solution that can help consumers who would otherwise choose vice over virtue to simultaneously increase consumption of healthy foods (virtues) and decrease consumption of unhealthy foods (vices) while still fulfilling taste goals — ‘vice-virtue bundles,’” said Dr. Kelly L. Haws, associate professor of management.
The focus should be on lowering the portion of the “vice” foods and correspondingly raising the portion of a healthy food to replace it.
The idea is to not give up entirely foods that provide pleasure but are not nutritious. Instead, the focus should be on lowering the portion of the “vice” foods and correspondingly raising the portion of a healthy food to replace it.
In a series of experiments, Haws and her colleagues found that people have a “taste-health balance point” — a proportion of vice and virtuous foods that make up one serving — which they find satisfactory.
For most, the perfect vice-virtue bundle is made up of a small (1/4) to medium (1/2) portion of vice.
So if a vice-virtue bundle was made up of fries and slices of apple, it might take a small or very small serving of fries to satiate the need for the vice food.
Haws is among five researchers who lay out their findings in “Vice-Virtue Bundles,” a paper under review for publication.
“Vice-virtue bundles could also be the answer for many in the food service industry who are actively seeking out healthy food options that consumers will voluntarily choose,” Haws said.
“Given that consumers consistently find vice-virtue bundles to be attractive, managers should consider adding vice-virtue bundles to their product lines,” Haws said.
“For restaurants and food vendors that already offer pure vice and virtue options, vice–virtue bundles provide an opportunity for product line expansion through existing items rather than through development of completely new offerings.
“This provides a potential opportunity for cost-savings, as many food establishments devote considerable resources to developing new product offerings, which can in turn increase inventory or production costs.”
This round of research did not mix in any pricing or marketing components, but the researchers say it would be easy for restaurants to pursue such experiments on their own.
“With the right marketing and the right choice sets, we believe that vice-virtue bundles offer exciting directions for future research and practice aimed at maximizing health without compromising tastes,” the researchers concluded.
