- Equally effective across diverse demographics.
- Highlights the importance of consumer awareness.
New Delhi, July 30 (NationPress) Salt warning labels on restaurant menus might encourage diners to reconsider their choices regarding high-salt meals and opt for healthier options, as indicated by a recent study.
This approach could serve as a significant method to combat cardiovascular diseases and the kidney damage associated with a high-salt diet.
In an unprecedented study, a team from the University of Liverpool in the UK examined the behavior of diners who saw salt warnings compared to those who viewed menus without any warnings.
The results, published in the journal The Lancet Public Health, revealed that consumers found these warning labels effective in deterring the selection of high-salt dishes. The labels also increased awareness regarding salt content and led to a notable reduction in the amount of salt ordered.
Lead author Dr. Rebecca Evans, a Postdoctoral Researcher in Psychology at the university, stated, "Our research indicates that salt warning labels on menus assist individuals in making healthier dietary choices."
"Given that excessive salt consumption is a primary factor contributing to diet-related illnesses, implementing such labeling policies could be crucial for enhancing public health."
The World Health Organization (WHO) recommends a daily salt intake of less than 5 grams (approximately under a teaspoon) or under 2g of sodium.
Annually, roughly 1.89 million deaths are linked to excessive salt intake. Many common dishes served in restaurants contain alarmingly high levels of salt, yet there are few policy measures to tackle this issue.
Research has shown that high salt consumption can elevate blood sodium levels, cause water retention, increase blood volume and pressure (hypertension), subsequently leading to strokes, cardiovascular diseases, kidney problems, osteoporosis, and obesity.
The study incorporated both an online and a real-world randomized controlled trial (RCT), with results indicating the potential effectiveness of menu labeling as a scalable public health initiative.
In the restaurant study, 454 participants were involved, and those provided with salt warning labeled menus ordered on average 12.5 percent (0.54g) less salt compared to diners with menus lacking warning labels, according to the researchers.
In the online RCT involving 2,391 UK adults, participants perceived salt warning labels as effective in discouraging high-salt item selections, leading to a 0.26g reduction in salt ordered per meal.
Across both trials, the labels proved equally effective regardless of age, gender, or education level, suggesting this intervention could benefit everyone, thus not exacerbating health inequalities.
Dr. Evans added, "This study illustrates that even minor nudges at the point of purchase can promote healthier decisions."
Point of View
The findings from the University of Liverpool present a compelling case for the implementation of salt warning labels on restaurant menus. This intervention could play a pivotal role in enhancing public health and addressing the pressing issue of diet-related diseases in our society. By fostering awareness about salt consumption, we can empower individuals to make informed dietary choices, ultimately reducing health disparities across the population.
