“…A crossover clinical trial was conducted at The Alamedilla Primary Care Research Unit belonging to the Spanish Network for Preventive Activities and Health Promotion (REDIAPP) and the Biomedical Research Institute of Salamanca (IBSAL). The protocol for the Breakfast Glycemic Index (BGI) study (NCT02616276) has recently been published [ 35 ]. For the sample population, 40 subjects aged 20–40 years were selected through consecutive sampling at urban primary care health centers in Salamanca, Spain between 2015 and 2016.…”

This study aimed to evaluate the postprandial effects of high and low glycemic index (GI) breakfasts on vascular function. It was a crossover trial that included 40 young healthy adults (50% women), aged 20–40 years, who were recruited at primary care settings. They consumed three experimental breakfasts in randomized order, each one separated by a 1-week washout period: (1) control conditions (only water); (2) low GI (LGI) breakfast (29.4 GI and 1489 KJ energy); and (3) high GI (HGI) breakfast (64.0 GI and 1318 KJ energy). Blood samples were collected at 60 and 120 min after each breakfast to determine glucose and insulin levels. Vascular parameters were measured at 15 min intervals. Augmentation index (AIx) was studied as a primary outcome. Secondary outcomes comprised glucose, insulin, heart rate (HR) and pulse pressures (PPs). We found a trend toward increased AIx, HR and PPs for the HGI versus the LGI breakfast. A significant interaction between the type of breakfast consumed and all measured parameters was identified (p < 0.05) except for central PP. Stratifying data by sex, this interaction remained significant for AIx and augmentation pressure only in males (p < 0.05). In conclusion, breakfast GI could affect postprandial vascular responses in young healthy adults.

“…Além disso, as crianças apresentam um estresse metabólico superior aos adultos durante o período do sono, consumindo uma maior quantidade de glicose dos estoques de glicogênio 33 . Nesse sentido, a ausência do CM na rotina das crianças pode provocar maiores concentrações de insulina pós-prandial, sugerindo uma inflexibilidade metabólica que pode ser prejudicial à homeostase glicêmica [34][35][36] . A regulação da glicose sanguínea pode ser um mecanismo responsável por alterar o desempenho em muitos domínios cognitivos, principalmente contra o seu declínio nas primeiras horas do dia, podendo facilitar a motivação, a concentração e a retenção de informações, processos cognitivos estes de fundamental importância para a realização de tarefas escolares 4,16,36 .…”

Introdução. A má alimentação e o sedentarismo estão entre os fatores que mais contribuem para o agravo do estado de saúde na infância, sendo associados a dificuldades e problemas de aprendizagem durante o período de escolarização. Estudos sugerem que crianças em idade escolar podem ter desempenho cognitivo aprimorado pelo consumo regular do café da manhã, bom condicionamento físico e da prática de exercícios físicos. Objetivo. Partindo do princípio de que muitas crianças em idade escolar não consomem o café da manhã todos os dias e, também não atingem as metas de exercício recomendadas por diretrizes de saúde, no presente estudo realizou-se uma revisão narrativa da literatura acerca do consumo do café da manhã, do envolvimento em práticas corporais de crianças, e a sua capacidade de manter e aprimorar as funções cognitivas na infância. Método. A investigação englobou aspectos de consumo, resposta glicêmica e a comparação de carboidratos alimentares presentes no café da manhã, além disso, o envolvimento em aulas de educação física, intervalos ativos e programas de exercício físico e a sua relação com a cognição de crianças em idade escolar. Conclusão. Após revisão de artigos e as suas respectivas contribuições científicas para as temáticas, assume-se uma associação positiva entre o consumo adequado do café da manhã e das práticas de exercício físico com o funcionamento cognitivo ideal para crianças em idade escolar. Sendo sugerido pelos autores pesquisados, a adoção e o incentivo dessas práticas para a rotina das crianças durante o período de escolarização.

BackgroundHigh blood pressure is an important risk factor for cardiovascular disease, contributing to about 50% of cardiovascular events worldwide and 37% of cardiovascular-related deaths in Western populations. Epidemiological studies suggest that cocoa-rich products reduce the risk of cardiovascular disease. Flavanols found in cocoa have been shown to increase the formation of endothelial nitric oxide which promotes vasodilation and therefore blood pressure reduction. Here we update previous meta-analyses on the e ect of cocoa on blood pressure. ObjectivesTo assess the e ects on blood pressure of chocolate or cocoa products versus low-flavanol products or placebo in adults with or without hypertension when consumed for two weeks or longer. Search methodsThis is an updated version of the review initially published in 2012. In this updated version, we searched the following electronic databases from inception to November 2016: Cochrane Hypertension Group Specialised Register, CENTRAL, MEDLINE and Embase. We also searched international trial registries, and the reference lists of review articles and included trials. Selection criteriaRandomised controlled trials (RCTs) investigating the e ects of chocolate or cocoa products on systolic and diastolic blood pressure in adults for a minimum of two weeks duration. Data collection and analysisTwo review authors independently extracted data and assessed the risks of bias in each trial. We conducted random-e ects meta-analyses on the included studies using Review Manager 5. We explored heterogeneity with subgroup analyses by baseline blood pressure, flavanol content of control group, blinding, age and duration. Sensitivity analyses explored the influence of unusual study design. Main resultsThirty-five trials (including 40 treatment comparisons) met the inclusion criteria. Of these, we added 17 trials (20 treatment comparisons) to the 18 trials (20 treatment comparisons) in the previous version of this updated review.Trials provided participants with 30 to 1218 mg of flavanols (mean = 670 mg) in 1.4 to 105 grams of cocoa products per day in the active intervention group. The control group received either a flavanol-free product (n = 26 treatment comparisons) or a low-flavanol-containing cocoa powder (range 6.4 to 88 mg flavanols (mean = 55 mg, 13 treatment comparisons; 259 mg, 1 trial).
