New Delhi: According to a recent study, food labels can lead to changes in consumers' intake of select nutrients, calories, and fat intake. Over the past two decades, labels on packaged foods, calorie counts on restaurant menus, front-of-pack labels encouraging healthier eating, and "low-sodium" or "fat-free" identifiers have been developed in order to promote healthier choices. This study tries to focus on whether these labels actually work.
A new meta-analysis of interventional studies, led by researchers from the Friedman School of Nutrition Science and Policy at Tufts University, assessed the effectiveness of multiple types of food labels. Researchers found that these approaches can impact some targets, but not others, for both consumer and industry behaviour.
The 60 interventional studies reviewed comprised of two million unique observations, including consumer reported dietary intakes, purchases, and sales receipts.
