Abstract
Background/Objectives: The increasing presence of "no added sugar" products in the Polish food market provides consumers and nutritionists with access to products with varying nutritional compositions. Comparing the nutritional and energy values of products with and without added sugar provides objective data on their composition, which is important for informed diet planning and for monitoring differences between product groups. Methods: The research material included a total of 1278 food products, including 744 labeled "without added sugar" and 534 containing added sugar, obtained from four online stores and three offline retail outlets in Poland in the second and third quarters of 2023. The product assessment was based on an analysis of the nutritional and energy value, expressed per 100 g of each product. Results: The quantitative analysis revealed that products with added sugar were characterized by a higher energy value and a statistically significantly higher content of saturated fatty acids, carbohydrates, and sugars. Conclusions: Comparison of selected product groups revealed significant differences in nutritional and energy values. Analyzing these differences provides a practical overview of product composition and can be a useful source of information for consumers and nutritionists.
