- Comparisons of Nutri-Score and NutrInform Battery on consumer preferences, objective understanding, and food choices among Portuguese consumersPublication . Vasseur, Théo; Fialon, Morgane; Marques-Vidal, Pedro; Pereira, Paula; Meirhaeghe, Aline; Galan, Pilar; Kesse-Guyot, Emmanuelle; Touvier, Mathilde; Deschasaux-Tanguy, Mélanie; Sarda, Barthélémy; Hercberg, Serge; Nabec, Lydiane; Julia, ChantalFront-of-pack nutrition labels (FoPLs) are a cost-effective measure to inform consumers about the nutritional values of foods and to help them make healthier food choices at the point of purchase. This study compared the preference and performance—objective understanding and food choices—of Portuguese consumers for two FoPLs: Nutri-Score and NutrInform Battery. An experimental study was conducted in 2022 on a representative sample of 1014 Portuguese adults (mean age = 45.1 ± 13.8 years; 49% women). Participants were randomly allocated to either the Nutri-Score or the NutrInform Battery group and asked to complete an online questionnaire testing their objective understanding of the label and the effect on purchase intentions for three food categories as well as perceived helpfulness and perception of the FoPL. In terms of participants' ability to identify the most nutritionally favourable foods, Nutri-Score outperformed NutrInform Battery in all categories, with the highest performance observed for the identification of the three foods of higher nutritional value within the breakfast product category (OR = 27.8 [19.4–39.9], P < .0001). Overall, with Nutri-Score, participants were more likely to intend to purchase more nutritionally favourable products than with NutrInform Battery (OR ranging from 2.01 [1.50–2.68] for breakfast cereals to 14.6 [10.2–20.9] for added fats, P < .0001). In terms of preference, Nutri-Score was more appreciated, and perceived as easier to use, more reliable, and more informative than NutrInform Battery. The Nutri-Score appeared to be a more appreciated and effective tool than NutrInform Battery for helping Portuguese consumers to choose foods with a better nutritional composition.
- Lower calcium and iron intake in adolescent gymnasts : a case of concern for youth sports nutritionPublication . Vicente, Filipa; Holanda, Marcela; Ramalho, Renata; Mendes, João; Marques-Vidal, Pedro; Pereira, PaulaObjectives: Diet is important for the appropriate development and maturation of young amateur athletes. The aim of this study was to determine whether young gymnasts were consuming adequate amounts of nutrients, particularly calcium and iron. Methods: This cross-sectional survey was conducted in Portugal's Almada and Lisbon regions in 2020. To determine if participants’ diet was adequate, weight, height, and skinfold measurements were taken. Dietary consumption was examined using two 24-h recalls. We collected data from 66 participants (60% females, 12–18 y of age), of whom 82% had normal weight and 39% had ideal body fat. Results: The daily total energy intake (TEI) was1605 ± 601 kcal. Of the TEI, 19%, 31%, and 50% were comprised of protein, fat, and carbohydrates, respectively. The most often consumed protein sources were poultry and ultra-processed meat products (52% and 45%, respectively). The average daily consumption of calcium and iron was 626 ± 293 and 9 ± 3 mg, respectively. Only 2 of the 66 participants had calcium intake within recommended levels, and 1of 5 had iron intake within recommended levels, the percentage of which was lower in girls than boys (7.5% versus 38.5%, P < 0.05). Conclusions: Despite having a sufficient macronutrient distribution, Portuguese gymnasts consume a high amount of ultra-processed items and a low amount of calcium and iron. The low proportion of female gymnasts with adequate iron consumption is cause for worry in sports nutrition.
