Sugar-free, low-fat claims could be misleading. Here’s how to decode food labels.
No-fat or no-sugar, low-fat, low-cholesterol or reduced-salt on food packaging may make you feel you are making healthy choices, but the claims rarely reflect the actual nutritional quality of the food, shows a new study in the Journal of the Academy of Nutrition and Dietetics.
“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 the University of North Carolina at Chapel Hill.
The study, which looked at data from more than 80 million food and beverage purchases in the US over five years, found that 13% of food and 35% of beverage purchases had a low-content claim (including no, free, low or reduced) and that low-fat was the most common claim, followed by low-calorie, low-sugar and low-sodium. “Products high in calories, sodium, sugar or fat may be more likely to have low- or no-content claims,” said Taillie.
It’s all relative
You assume reduced means a healthier product, but what the label means is that product has reduced amounts of an ingredient in reference to the original product. For example, a three-cookie serving of reduced-fat Oreos contains 4.5 grams of fat compared to 7 grams in a serving of full-fat Oreos, but both contain 14 grams of sugar per serving, which doesn’t make the low-fat version is “healthy.”
Chocolate low-fat milk may have lower fat content but it is higher in sugar relative to plain milk and higher in sugar and fat relative to other drinks.
Foods with a “low” claim are equally confusing, but for different reasons. The FDA allows a low-fat label on food if that food has less than three grams per reference amount customarily consumed (RACC), which varies across product categories. For example, the RACC for brownies is 40 grams, whereas the RACC for cheesecake is 125 grams.
“A low-fat brownie could have three grams of fat per 40 grams, whereas a low-fat cheesecake” would have to have three grams of fat per 125 grams. So if a consumer were trying to find a lower-fat option for a dessert, the low-fat brownie would have relatively higher fat than the low-fat cheesecake.”
