Researchers said changing packaging on meat and dairy-free products, which often proudly tout their vegan status, could result in more people selecting them.

People are more likely to pick a meat-free option if it’s not labelled vegan, a study suggests.

Foods described as “healthy”, “sustainable” or “plant-based” are all more appealing, according to the University of Southern California.

Its research saw more than 7,000 people asked to choose between a vegan food basket and one with meat and dairy.

The former was randomly labelled “vegan”, “plant-based”, “healthy”, “sustainable” or “healthy and sustainable”.

The experiment found people were more likely to select it when the focus was on its benefits (such as “sustainable”) rather than its content, though “plant-based” was still more popular than “vegan”.
