Terms such as no-fat or no-sugar, low-fat or reduced-salt on food packaging may give consumers a sense of confidence before they purchase, but these claims rarely reflect the actual nutritional quality of the food, according to a new study led by researchers at the University of North Carolina at Chapel Hill.
The work, which appears in the most recent issue of the Journal of the Academy of Nutrition and Dietetics, rekindles an ongoing debate on what United States regulators consider healthy labeling, as producers and interest groups grapple over rules on nutrition claims on packaged foods and ready-to-drink beverages – and consumers contend with how to rationalize a purchase and make healthier choices.
“In many cases, foods containing low-sugar, low-fat or low-salt claims had a worse nutritional profile than those without claims,” explained lead investigator Lindsey Smith Taillie, a research assistant professor in the department of nutrition at UNC’s Gillings School of Global Public Health. “In fact, in some cases, products that tend to be high in calories, sodium, sugar or fat may be more likely to have low- or no-content claims.”
For example, a three-cookie serving of reduced-fat Oreos contains four-and-a-half grams of fat compared to seven grams in a serving of full-fat Oreos, but both still contain 14 grams of sugar per serving, which could provide the appearance that the low-fat version is “healthy.” Chocolate low-fat milk is another example. It has the lower fat content but it is higher in sugar relative to plain milk and higher in sugar and fat relative to other beverages.
