“…The premise that acute interventions can enhance mental performance in this population, in whom cognitive function is well protected, is now being reconsidered (8) . Increasingly, interest has turned towards groups who may be more vulnerable to nutritional deficits or cognitive impairment, for example, children and the elderly (9) . Breakfast consumption, as with other meals, provides fuel for preferential oxidation of glucose.…”

Breakfast is recommended as part of a healthy diet because it is associated with healthier macroand micronutrient intakes, BMI and lifestyle. Breakfast is also widely promoted to improve cognitive function and academic performance, leading to the provision of breakfast initiatives by public health bodies. Despite this positive and intuitive perception of cognitive benefits, there has been no systematic review of the evidence. Systematic review methodology was employed to evaluate the effects of breakfast on cognitive performance in well-nourished children and nutritionally at-risk or stunted children. Acute experimental studies, school feeding programmes and studies of habitual breakfast intake are reviewed. Comparisons of breakfast v. no breakfast and breakfasts differing in energy and macronutrient composition are discussed. Included are forty-five studies described in forty-one papers published between 1950 and 2008. The evidence indicates that breakfast consumption is more beneficial than skipping breakfast, but this effect is more apparent in children whose nutritional status is compromised. There is a lack of research comparing breakfast type, precluding recommendations for the size and composition of an optimal breakfast for children's cognitive function. Few studies examined adolescents. Studies of school breakfast programmes suggest that such interventions can have positive effects on academic performance, but this may be in part explained by the increased school attendance that programmes encourage. The present systematic review considers methodological issues in this field and makes recommendations for future research design and policy priorities.

“…Mood state is known to modulate cognitive function (96) ; however, the direction of the relationship is not straightforward (97) . Other research has documented effects of food on cognitive function in the absence of alterations in mood and direct mechanisms of action, for example, via alterations in glucose availability or nutrient-induced synthesis of neurotransmitters (see Gibson & Green (97) and Dye & Blundell (98) ).…”

Foods and dietary patterns that enhance satiety may provide benefit to consumers. The aim of the present review was to describe, consider and evaluate research on potential benefits of enhanced satiety. The proposal that enhanced satiety could only benefit consumers by a direct effect on food intake should be rejected. Instead, it is proposed that there is a variety of routes through which enhanced satiety could (indirectly) benefit dietary control or weight-management goals. The review highlights specific potential benefits of satiety, including: providing appetite control strategies for consumers generally and for those who are highly responsive to food cues; offering pleasure and satisfaction associated with low-energy/healthier versions of foods without feeling 'deprived'; reducing dysphoric mood associated with hunger especially during energy restriction; and improved compliance with healthy eating or weight-management efforts. There is convincing evidence of short-term satiety benefits, but only probable evidence for longer-term benefits to hunger management, possible evidence of benefits to mood and cognition, inadequate evidence that satiety enhancement can promote weight loss, and no evidence on which consumers would benefit most from satiety enhancement. The appetite-reducing effects of specific foods or diets will be much more subtle than those of pharmaceutical compounds in managing hunger; nevertheless, the experience of pharmacology in producing weight loss via effects on appetite suggests that there is potential benefit of satiety enhancement from foods incorporated into the diet to the consumer.

Objective: The aim of this study was to analyze qualitatively how women, who have recovered from anorexia nervosa, perceive and describe their current eating practices, as well as the ones developed during the eating disorder period. Methods: Seven women were interviewed individually with the objective of investigating their eating practices, transition phases and all relevant aspects that somewhat contributed to the habit-forming; experiences, feelings and perceptions related to mealtime and the influence that food has had over the present subjects' life. The interviews were analyzed by the discourse of the collective subject method. results: The results brought up the following topics: a) control; b) concerns and feelings; c) deprivation d) beauty dictatorship; e) eating competence; f) importance of food; g) food cacophony. conclusions: What stands out is a multiplicity of eating practices, which during the eating disorder were similar to and characterized by restriction; however, after recovery, part of the subjects seem to have developed a higher eating competence, whereas others show a practice similar to the one acquired during the anorexia nervosa, such as the difficulty in realizing when they are satisfied and a feeling of discomfort when facing social interactions. reSUMO Objetivo: Este artigo teve como objetivo analisar qualitativamente como mulheres que se recuperaram da anorexia nervosa percebem e relatam suas práticas alimentares atuais, bem como as práticas vigentes no período do transtorno. Métodos: Foram feitas sete entrevistas individuais com mulheres que vivenciaram a anorexia nervosa. Estas abordaram: hábitos alimentares das entrevistadas; mudanças e fatores importantes para a formação destes; vivências, sentimentos e percepções associados ao momento da refeição; e a influência que a alimentação exerce na vida das participantes hoje. A análise dessas deu-se a partir da técnica do Discurso do Sujeito Coletivo. resultados: Os resultados trouxeram os seguintes temas: a) controle; b) preocupações e sensações; c) privação d) ditadura da beleza; e) competência alimentar; f) importância da alimentação; g) cacofonia alimentar. conclusões: Destaca-se Original article Ulian MD et al. nesses a multiplicidade das práticas alimentares, que durante o transtorno se assemelham e se caracterizam pela restrição; no entanto, após a recuperação dos sujeitos, alguns parecem ter desenvolvido maior competência alimentar, enquanto outros apresentam práticas semelhantes às vigentes na anorexia nervosa, além de dificuldade de perceberem quando estão satisfeitos e sensação de desconforto em situações de interação social.
