- Docosahexaenoic acid supplementation for children with attention deficit hyperactivity disorder: a comprehensive review of the evidencePublication . Ramalho, Renata; Pereira, Ana Colaço; Vicente, Filipa; Pereira, PaulaAttention deficit hyperactivity disorder (ADHD) is considered the most common behavioural disorder in school-age children. ADHD is a complex and multifactorial disorder characterised by a variety of symptoms, including concentration problems, excessive motor activity and impulsivity which interferes with execution of simple school tasks. Diagnosis has been essentially subjective, since no specific laboratory tests are available. However, ADHD remains overdiagnosed, probably due to social pressures for children to be successful in school from an early age, which leads parents to seek medical support. Although therapeutic approaches for ADHD have been essentially pharmacologic, in recent years several studies were performed to investigate the role of nutrition, especially omega 3 polyunsaturated fatty acid (omega 3-PUFA), in the development and treatment of this disorder. In this review, the authors gathered the most relevant evidence regarding omega 3-PUFA, mainly docosahexaenoic acid, as coadjutant or as a single therapy, in the management of ADHD symptoms. The authors also reviewed this disorder's current medical and therapeutic features.

- Effectiveness of a nutrition education programme on nutritional knowledge in young football players : a pilot studyPublication . Vicente, Filipa; Anastácio, Leandro; Monteiro, Andreia; Brito, José; Ramalho, Renata; Pereira, PaulaBackground: Adequate nutrition is fundamental to the health and performance of young athletes. However, many fail to meet nutritional recommendations. Nutrition education programmes are promising, cost-effective strategies for improving dietary habits. However, research gaps persist, coupled with notable variability amongst the intervention programmes targeting youth athletes. The aim of this study was to assess the nutritional knowledge of Portuguese youth athletes and to evaluate the effectiveness of a nutrition education programme in improving football players’ understanding of a healthy diet. Methods: Participants were recruited from a local football club through public announcement. Male youth football players aged 13 to 18 years, training at least 3 times per week and competing regularly over the past six months, were eligible. The baseline assessment included anthropometric measurements, an assessment of the adherence to the Mediterranean diet using the KIDMED questionnaire, and an assessment of general and sports nutrition knowledge via a structured questionnaire. Following the intervention—comprising three face-to-face educational sessions and two digital infographics—the KIDMED and nutrition knowledge questionnaires were re-administered. Results: A sample of 38 male footballers were eligible for this study. Most participants exhibited a healthy body weight, with a corresponding adequate body composition. The mean KIDMED score indicated moderate adherence to the Mediterranean diet with no statistically significant difference between the baseline and post-intervention (6.79 ± 1.52 versus 6.97 ± 2.01, p > 0.05). There was a significant enhancement in overall nutrition knowledge, accompanied by notable improvements in the comprehension of macro- and micronutrient sources and sports nutrition principles. Conclusions: This pilot programme proved effective in enhancing young football players’ knowledge of nutrient sources and sports nutrition.

- Health professionals’ knowledge and attitudes towards baby led weaning : a cross-sectional, exploratory, and observational studyPublication . Sarreira-de-Oliveira, Paula; Ramalho, Renata; Antunes, Ricardo; Antunes, Vanessa; Loureiro, FernandaBaby Led Weaning (BLW) is a type of infant feeding that allows babies to feed themselves and has gain popularity among parents in recent years. Health professionals’ (HP) knowledge and attitudes towards BLW is less explored. We conducted a cross-sectional, exploratory, and observational study, with a web-based instrument, that aimed to determine the knowledge and attitudes of HP familiar to BLW regarding the use of this method in complementary feeding. In our sample of 118 HP, HP who were women or younger (23–39 years) had a more positive perception of BLW. We found that acceptance and positive attitudes towards BLW were consistent among HP. It is essential to improve the training of HP in the specifics of implementing this approach and to develop clear guidelines to guide practice.
- Ketogenic diet and neuroinflammation : implications for neuroimmunometabolism and therapeutic approaches to refractory epilepsyPublication . Guerreiro, Daniela; Almeida, Anabela; Ramalho, RenataRefractory epilepsy, characterized by seizures that do not respond to standard antiseizure medications, remains a significant clinical challenge. The central role of the immune system on the occurrence of epileptic disorders has been long studied, but recent perspectives on immunometabolism and neuroinflammation are reshaping scientific knowledge. The ketogenic diet and its variants have been considered an important medical nutrition therapy for refractory epilepsy and may have a potential modulation effect on the immune system, specifically, on the metabolism of immune cells. In this comprehensive review, we gathered current evidence-based practice, ketogenic diet variants and interventional ongoing clinical trials addressing the role of the ketogenic diet in epilepsy. We also discussed in detail the ketogenic diet metabolism and its anticonvulsant mechanisms, and the potential role of this diet on neuroinflammation and neuroimmunometabolism, highlighting Th17/Treg homeostasis as one of the most interesting aspects of ketogenic diet immune modulation in refractory epilepsy, deserving consideration in future clinical trials.
- 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.
