Study finds climate impact labels on sample fast food menu had strong effect on food selection

A brand new research has discovered that together with local weather affect labels on a pattern quick meals menu influenced members’ meals selections in favor of extra climate-friendly objects. The research was led by a researcher on the Johns Hopkins Bloomberg College of Public Well being.

For the research, greater than 5,000 on-line members have been proven a pattern menu resembling a quick meals menu and requested to decide on a single merchandise for dinner. One group of members obtained a menu with non-red meat menu objects corresponding to rooster sandwiches labeled “low local weather affect.” One other group obtained a menu with crimson meat objects—burgers—labeled “excessive local weather affect.” A 3rd management group obtained menus with QR codes on all objects and no local weather labels.

Each the excessive and low local weather affect labels markedly decreased crimson meat choices in comparison with the management group, with the excessive affect labels having a robust impact. Menus with a “excessive local weather affect” label on burgers elevated non-beef selections by 23% in comparison with the management group. Menus that included “low local weather affect” labels elevated non-beef selections, corresponding to a rooster sandwich or a salad, by about 10% extra members than these within the management group.

The research was printed on-line December 27 in JAMA Community Open.

“These outcomes recommend that menu labeling, notably labels warning that an merchandise has excessive local weather affect, might be an efficient technique for encouraging extra sustainable meals selections in a quick meals setting,” says research lead creator Julia Wolfson, Ph.D., affiliate professor within the Division of Worldwide Well being on the Bloomberg College.

Utilizing labels on menus has lengthy been seen as a possible method for selling healthful and sustainable meals choices.

For his or her research, Wolfson and her co-authors wished to check how signaling local weather change impacts of quick meals menu objects would possibly immediate individuals to go for much less crimson meat. Purple meat consumption has been linked to well being issues corresponding to colorectal most cancers, stroke, kind 2 diabetes, and different diseases. Much less consumption of crimson meat additionally would additionally assist to decrease greenhouse gasoline emissions which might assist scale back local weather change as a result of beef manufacturing is the biggest contributor of greenhouse gasoline emissions within the meals and agriculture sector.

The research was fielded from March 30 to April 13, 2022, and included 5,049 nationwide members. The “low local weather affect” labels for vegetarian, rooster, or fish menu objects have been inexperienced. The “excessive local weather affect” labels for all beef burger selections have been crimson. The authors primarily based the excessive/low affect local weather classes on proof that beef has excessive local weather affect in comparison with different proteins.

Along with being requested to decide on an merchandise for dinner, members have been requested to charge how wholesome they thought the merchandise they ordered was. Irrespective of which kind of label was on the menu seen, members who chosen a extra sustainable (i.e., non-beef) merchandise perceived their option to be more healthy in comparison with those that chosen a beef merchandise.

To evaluate the healthfulness of the pattern menu objects, the researchers utilized a broadly used measure known as the Dietary Profiling Index. The Index measures the healthfulness of meals on a 100-point scale, with 64 and decrease thought-about healthful. The researchers discovered that the alternatives of the “excessive local weather affect” label group scored barely higher than these of the management group and the “low local weather affect” group. Nevertheless, not one of the objects on the menu scored excessive sufficient to be thought-about optimally healthful.

Whereas encouraging on the entire, the outcomes recommend that positively framed “low local weather affect” labels are much less efficient in encouraging sustainable meals selections in comparison with “excessive local weather affect” labels. On the identical time, local weather labels could have the undesirable facet impact of constructing a alternative appear more healthy than it truly is.

“An undeserved well being halo conferred to unhealthy menu objects may encourage their overconsumption,” Wolfson says. “So we have now to search for labeling methods that create ‘win-wins’ for selling each extra sustainable and wholesome selections.”

Wolfson and her colleagues intention to do related research in additional real-world food-choice settings.
