In April 2022, England started a new rule that requires large food Businesses, those with more than 250 workers, to show calorie counts on their menus. This rule is aimed at food places where food is made to eat right away, such as restaurants and cafes. The goal of this rule is to help people make better food choices by showing them how many calories are in their meals. Eating out is often linked to poorer eating habits and higher calorie intake, so the government hopes that by showing calorie information, people might choose healthier options.
Calorie labels have been used in other countries, like parts of Australia, Canada, and the United States. However, studies have shown mixed results on whether these labels actually change what people choose to eat. Some studies suggest that having calorie information leads to lower calorie options being offered on menus.
How Calorie Labeling Works
Businesses can calculate the calories in their food in several ways. They can use values from the manufacturer, average values from similar ingredients, or trusted food databases. The calorie information must be shown next to the serving size and include a note saying that adults need about 2000 calories each day. There is a bit of leeway allowed, where a business can be off by 20% on their calorie counts. However, local enforcement officers, who are responsible for making sure businesses follow these rules, might find it hard to check if the calorie counts are accurate.
In the United States, many businesses followed the rule for calorie labeling early on. A similar trend was seen in England, where a large number of businesses provided calorie information just months after the rule was implemented. Despite this, recent reports indicate that some big chains in the U.S. were not properly reporting calorie information in all required ways. There is a concern that the food industry often finds ways to get around government rules, which may be due to a lack of accountability and resources to check compliance.
The Accuracy of Calorie Labels
There has been research showing that calorie labels on packaged foods can sometimes be inaccurate. For example, one study found that popular snacks in the U.S. often had more calories than shown on their labels. In Canada, a different study tested over 1000 food Items and found that calories were often underreported. Some items had calorie counts that were more than 20% higher than what was listed.
None of the existing research has looked specifically at how accurate calorie labels are in the out-of-home food sector in England since the new rules were put in place. This is important because if people rely on these labels when planning their daily calorie intake, any inaccuracies could mean they end up consuming more calories than they think. Moreover, if consumers notice that calorie labels are often wrong, they might stop trusting them altogether.
Study Overview
To address this, a study was conducted to check the accuracy of calorie labels in food outlets after the new rules were introduced. The research was done in two different local areas in England: Liverpool and Milton Keynes. By choosing these two locations, the study aimed to get a good mix of different types of neighborhoods, including both poorer and wealthier areas.
Businesses that serve food and have a large number of employees were identified for the study. Then, a total of 60 outlets were selected including cafes, restaurants, fast food places, and pubs. Researchers made sure to pick a variety of food items from each type of outlet.
Menu Item Selection
For the study, different kinds of food items were collected from each outlet. The researchers randomly selected one item from various categories such as starters, main dishes, desserts, the most popular item, and an item that might be inaccurately labeled.
A total of 300 items were gathered from the 60 outlets. The researchers recorded the calorie information shown on the menus and then ordered the food to measure the actual calories in each item. They ensured that the scales used for weighing the food were accurate and sent samples to a laboratory for precise calorie analysis.
Results of the Study
The study found that the average number of calories reported on menus was higher than what was actually Measured. Overall, out of all sampled items, about 56% had less measurable calories than what was shown on the menu. Furthermore, 35% of the items had calorie counts that were outside the allowed 20% range, with many of these having much higher calorie counts than reported.
When looking at specific types of outlets, pubs showed the most significant differences. Many items in pubs had calorie counts that were not just slightly off, but considerately more than what was reported. Despite finding some instances of under-reporting, the more common issue was over-reporting calorie counts.
Comparison Between Locations
The research also compared the calorie counts for similar menu items across the two local areas. It found that there were not significant differences in the measured calorie counts between the same types of food served in Liverpool and Milton Keynes. This suggests that most outlets in the same chain generally offer similar calorie counts in their food items.
Factors Influencing Accuracy
Several factors were looked at to see if they influenced how accurate the calorie counts were. Items with higher reported calorie counts tended to have larger discrepancies between reported and measured values. Pubs and restaurants tended to have bigger differences compared to cafes. Certain types of items, like popular dishes, also showed larger differences.
No clear patterns were found for potentially inaccurate items, indicating that it is hard to identify which items are more likely to have wrong calorie counts just by looking at the menu. This raises concerns for the enforcement of the calorie labeling rules.
Conclusion
The findings highlight that calorie counts on menus in the out-of-home sector in England are often inaccurate. There were significant differences, with many items having either over- or under-stated calorie content. These discrepancies could lead to consumers unknowingly exceeding their calorie intake, which goes against the very purpose of calorie labeling.
The research points out that while the new rules are in place, there is a need for better accuracy in calorie counts. Businesses may benefit from regular checks to ensure that the calorie information they provide is correct. Since large chains often have similar offerings across their outlets, performing checks at a larger scale could help maintain consistency and accuracy in calorie labeling.
In conclusion, while calorie labeling is a step toward promoting healthier eating habits, the current accuracy of these labels in England's out-of-home food sector needs addressing to truly benefit consumers.
Title: Accuracy of menu calorie labelling in the England out-of-home food sector during 2024: Assessment of a national food policy
Abstract: Mandatory calorie labelling was introduced in out-of-home (OOH) food sector outlets during 2022 in England. Previous research in North America has found labelled energy content can be underestimated for packaged and quick-serve foods, but no study has evaluated the accuracy of out-of-home food sector menu calorie labelling in response to the mandatory policy introduced in England. N=295 menu items from a range of outlet types (e.g. cafes, pubs, restaurants) and menu categories (e.g., starters and sides, main, dessert) were sampled. Bomb calorimetry was used to quantify energy content and the reported energy content on menus was recorded. Consistency of measured energy was assessed by sampling the same items across outlets of the same business (N=50 menu items). Differences between reported and measured energy content were tested through Wilcoxon Signed Rank tests, and a linear model examined correlates of the difference. Mean measured kilocalories (kcal) were significantly lower than reported kcal (-16.70kcal ({+/-}149.19), V=16920, p20%) to measured energy content for 35% of sampled menu items. There were significant inaccuracies in reported energy content of calorie labelled menu items in English food outlets subject to mandatory calorie labelling and this appears to be caused by both over- and under-estimation of reported energy content. HighlightsO_LI- Energy content measured by bomb calorimetry was significantly higher than on menus. C_LIO_LI- Both under and over estimation of food energy content were frequently observed. C_LIO_LI- Measured energy content was consistent across chain outlets in different locations. C_LI
