Effect of a cajuína hydroelectrolytic drink on the physical performance and hydration status of recreational runners.

Cajuína is a processed drink derived from cashew and is widely consumed in the northeast region of Brazil. This study evaluated the effect of a cajuína-based hydroelectrolytic drink on the aerobic performance and hydration status of recreational runners. Seventeen males (31.9 ± 1.6 years, 51.0 ± 1.4 ml/kg/min) performed three time-to-exhaustion running sessions on a treadmill at 70% VO2max, ingesting cajuína hydroelectrolytic drink (CJ), high carbohydrate commercial hydroelectrolytic drink (CH) and mineral water (W) every 15 min during the running test. The participants ran 80.3 ± 8.4 min in CJ, 70.3 ± 6.8 min in CH and 71.8 ± 6.9 min in W, with no statistical difference between procedures. Nevertheless, an effect size of η2 = 0.10 (moderate) was observed. No statistical difference was observed in the concentrations of sodium, potassium, and osmolality in both serum and urine between the three conditions. However, the effect size was moderate (urine sodium) and high (serum sodium, potassium, and osmolality). Urine specific gravity, sweating rate and heart rate were not significantly different between drinks. The cajuína-based hydroelectrolytic drink promotes similar effects compared to commercial hydroelectrolytic drink and water, considering specific urine gravity, heart rate, sweating, and time to exhaustion in recreational runners.

EFFECT OF FOOD AND NUTRITION EDUCATION INTERVENTIONS ON WEIGHT AND ANTHROPOMETRIC MEASURES OF SCHOOL CHILDREN / EFECTO DE LAS INTERVENCIONES DE EDUCACIÓN ALIMENTARIA Y NUTRICIONAL SOBRE LAS MEDIDAS ANTROPOMÉTRICAS DE LOS NIÑOS ESCOLARES / Efeito De Intervenções De Educação Alimentar E Nutricional Nas Medidas Antropométricas De Escolares

ABSTRACT: The objective was to identify in the scientific literature which food and nutrition education interventions promote the reduction of anthropometric measures in schoolchildren. Methods: integrative literature review. The search was carried out in the following databases: PUBMED, SCIELO (Online Electronic Scientific Library) and LILACS (Latin American Literature in Health Sciences). The search terms used in the Health Sciences (DeCS) and MESH descriptors: child AND food AND educational nutrition AND obesity. Data collection took place in October and November 2021. Conclusion: the strategies that had the most results for reducing measures in schoolchildren, based on the collected studies, were the distribution of pamphlets and meetings with schoolchildren in which themes were addressed on the proportions of healthy eating; Educational game and weekly lectures on topics related to healthy eating; educational workshops on the preparation of snacks with fruit and the development of health education programs with topics on nutrition and physical activity. The introduction of nutritional food education actions should be carried out from the beginning of school life so that individuals develop an interest and curiosity for food and thus acquire healthy habits to maintain body weight properly.

RESUMEN: El objetivo fue identificar en la literatura científica qué intervenciones en educación alimentaria y nutricional promueven la reducción de medidas antropométricas en escolares. Métodos: revisión integrativa de la literatura. La búsqueda se realizó en las siguientes bases de datos: PUBMED, SCIELO (Biblioteca Científica Electrónica en Línea) y LILACS (Literatura Latinoamericana en Ciencias de la Salud). Los términos de búsqueda utilizados en los descriptores de Ciencias de la Salud (DeCS) y MESH: niño Y alimentación Y nutrición educativa Y obesidad. La recolección de datos se llevó a cabo en los meses de octubre y noviembre de 2021. Conclusión: las estrategias que tuvieron más resultados para la reducción de medidas en escolares, a partir de los estudios recolectados, fueron la distribución de folletos y reuniones con escolares en los que se abordaron temas sobre las proporciones de salud comiendo; Juego educativo y conferencias semanales sobre temas relacionados con la alimentación saludable; talleres educativos sobre la preparación de refrigerios con frutas y el desarrollo de programas de educación en salud con temas de nutrición y actividad física. La implantación de acciones de educación alimentaria nutricional debe llevarse a cabo desde el inicio de la vida escolar para que las personas desarrollen el interés y la curiosidad por la comida y así adquieran hábitos saludables para mantener adecuadamente el peso corporal.  

RESUMO: O objetivo foi identificar na literatura científica quais as intervenções de educação alimentar e nutricional promovem a redução das medidas antropométricas em escolares. Métodos: revisão integrativa da literatura. A busca foi realizada nas seguintes bases de dados: PUBMED, SCIELO (Biblioteca Científica Eletrônica em Linha) e LILACS (Literatura Latino-Americana em Ciências da Saúde). Os termos de busca utilizados nos descritores em Ciências da Saúde (DeCS) e MESH: child AND food AND nutrition educativo AND obesity. A coleta de dados ocorreu no mês de outubro e novembro de 2021. Conclusão: as estratégias que tiveram mais resultados para redução de medidas em escolares, com bases nos estudos coletados, foram a distribuição de panfletos e encontros com os escolares na qual foram abordados temas sobre as proporções de alimentação saudável; Jogo didático e palestras semanas abordando temas pertinentes à alimentação saudável; oficinas educativas de elaboração de lanches com frutas e o desenvolvidos de programas de educação em saúde com tópicos de nutrição e atividade física. A introdução das ações de educação alimentar nutricional devem ser feitas desde o início da vida escolar para que os indivíduos desenvolvam o interesse e curiosidade pelos alimentos e assim possam adquirir hábitos saudáveis para a manutenção do peso corporal de forma adequada.  

Lycopene-Rich Extract from Red Guava (Psidium guajava L.) Decreases Plasma Triglycerides and Improves Oxidative Stress Biomarkers on Experimentally-Induced Dyslipidemia in Hamsters.

This work assessed the effects of a 28-day treatment with lycopene-rich extract (LRE) from red guava fruit (Psidium guajava L.) on the lipid profile and oxidative stress in an experimental model of dyslipidemia. Male hamsters (116.5 ± 2.16 g) were fed with the AIN 93G diet containing casein (20%), coconut fat (13.5%) and cholesterol (0.1%). The animals were divided into four groups: normolipidemic control (standard feed; NC, n = 7); hypercholesterolemic control (HC, n = 7); LRE 25 mg/kg/day (LRE-25, n = 7) and LRE 50 mg/kg/day (LRE-50, n = 9). After treatment, plasma concentrations of triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL) cholesterol (LDL-c), high-density lipoprotein (HDL) cholesterol (HDL-c), malondialdehyde (MDA-p) and myeloperoxidase (MPO), as well as erythrocytic superoxide dismutase (SOD-e) and the atherogenic index, were determined. Malondialdehyde (MDA-h), catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD-h) levels were assessed. Feed intake (FI) and weight gain (WG) were also determined. The LRE-25 group presented significantly lower TG levels and atherogenic index than did the HC group (p < 0.05). Both LRE-25 and LRE-50 groups presented lower levels of MDA-p and MPO than did the HC group (p < 0.05). LRE demonstrated a promising effect against dyslipidemia and oxidative stress.
