AbstractObjectiveTo evaluate the validity of food photographs used to support the reporting of food intake with an FFQ designed for adolescents from Rio de Janeiro, Brazil.DesignA set of ninety-five food photographs was elaborated. The photographs’ evaluation process included the acknowledgement of foods and portions in the pictures. In the identification of foods (ninety-five photographs) and typical portions (twelve photographs), the adolescents were requested to answer a structured questionnaire related to the food photographs. The identification of the portion size of amorphous foods (forty-three photographs) was performed using three different portion sizes of actual preparations. The proportions (and 95 % confidence intervals) of adolescents who correctly identified foods and portion size in each photograph were estimated.SettingA public school in Niterói, Rio de Janeiro State, Brazil.SubjectsSixty-two adolescents between 11·0 and 18·9 years old, randomly selected.ResultsAt least 90 % of adolescents correctly identified the food in ninety-two photographs and the food in the three remaining photographs was recognized by 80–89 % of the adolescents. At least 98 % of the adolescents correctly identified eleven typical or natural portions in the food photographs. For amorphous foods, at least 70 % of teenagers correctly identified the portion size in the photograph of thirty-one foods; for the other photographs, the portion size was correctly recognized by 50–69 % of the adolescents for eight foods and by less than 50 % of adolescents for four foods.ConclusionsThe analysed photographs are appropriate visual aids to the reporting of food consumption by adolescents.

Normal Food

Portion sizes of commercially available foods have increased, and there is evidence that exposure to portion sizes recalibrates what is perceived as ‘normal’ and subsequently, how much food is selected and consumed. The present study aims to explore the role of social (descriptive and injunctive) and personal portion size norms in this effect. Across two experiments, participants were either visually exposed to (Study 1, N = 329) or actually served (Study 2, N = 132) a smaller or larger than normal food portion. After 24 h, participants reported their intended consumption (Study 1) or served themselves and consumed (Study 2) a portion of that food and reported perceived portion size norms. In Study 1, visual exposure to portion size did not significantly affect intended consumption and perceived portion size norms. In Study 2, participants consumed a smaller portion of food when they were served a smaller rather than a larger portion the previous day, which was mediated by perceived descriptive and injunctive social (but not personal) portion size norms. Results suggest that being served (but not mere visual exposure to) smaller (relative to larger) portions changes perceived social norms about portion size and this may reduce future consumption of that food.

Nocturnal Period

Hepatic-portal infusions of isotonic glucose did not influence food intake in free-feeding rabbits. In contrast, several other macronutrients and some of their metabolites, infused via the same route, cause anorexia followed by prolonged hypophagia. Its duration was generally decreased when the same infusions were performed during the nocturnal period. Vagotomy did not significantly alter the food intake responses to hepatic-portal infusions of either glucose or the other experimental substances. The results of related experiments have demonstrated that prolonged anorexia was not a consequence of the fast infusion rate or the generalized behavioral mallaise. However, when the infusions of most anorexigenic substances were followed by intraperitoneal administration of insulin, the duration of anorexia was shortened and food consumption was elevated. The results provided indirect evidence for the vagally mediated regulatory contribution of the previously studied neural and humoral intestinal mechanisms which are bypassed by infusing nutrient loads directly into the hepatic-portal circulation.

Four new Brazilian species of Ruppeliana are described and illustrated: R. barbarensis sp. nov., R. grossii sp. nov., R. longiphallus sp. nov., and R. serrana sp. nov., the first from Minas Gerais State and the other three from Rio de Janeiro State. The new taxa can be easily distinguished from other Ruppeliana species by their color pattern and male genitalia morphology. Ruppeliana coronulifera (Stål, 1862) and R. taschenbergi (Berg, 1899) are synonymized with R. signiceps (Stål, 1862). Additionally, a diagnosis of the genus and a key to species are provided.

The aim of this study was to compare the population structure of the invasive bivalve Isognomon bicolor in three different areas on the coast of Rio de Janeiro State and to verify its temporal variation. All the areas presented high densities, reaching more than 1000 live individuals per 100 cm2. The number of dead individuals and recruits was higher in Ilha do Brandão (Angra dos Reis) than in the other areas. The individuals sampled at Praia Vermelha (Rio de Janeiro) presented the highest maximum and mean sizes, compared to those found at Ilha do Brandão. In this area, vermetid molluscs are dominant and build a complex reef structure where only a few individuals of I. bicolor can really grow.

A species of the genus Amorphinopsis is described for the first time for the Atlantic Ocean. The new species was described based on the study of 25 specimens, collected in the area of the São Sebastião Channel and its environs (northern sector of São Paulo State coastline) and in the Cabo Frio region (Rio de Janeiro State). The form is massive cushion-shaped, lobate, occasionally encrusting. The megascleres are styles [160–260 (N=20)/5–10 (N=10) μm; length/thickness] and oxeas [150–900 (N=100)/5–18 (N=20) μm]. Amorphinopsis atlantica sp. nov. differs from the other species of Amorphinopsis by its colour, dark-greyish-green with or without yellow tinges on the exposed surface, and the smaller size of its oxeas. Amorphinopsis excavans is the closest species to the Brazilian material, but can still be set apart by a series of smaller traits, such as oxeas and styles never overlapping (the smaller oxea is always larger than the larger style).

Bilateral Lesions

The glucoprivation effects of 2-deoxy-D-glucose (2DG) on feeding behavior were studied in rats with bilateral lesions of the dorsomedial hypothalamic nucleus (DMN) and sham-operated controls. The lesioned and sham-operated rats were injected intraperitoneally with 2DG (5% wt/vol) at doses of either 150 mg/kg, 300 mg/kg, or 500 mg/kg, or with saline ("control days"). At all doses significantly more sham-operated rats ate and showed an increased food consumption during the first few hours after 2DG injection when compared to saline control days. However, their 24-h food consumption was normal or less than normal, depending on the dose of 2DG. On the other hand, rats with DMN lesions (DMN-L) did not increase their food consumption during the 4 h after the injection at any of the 2DG doses. In a second experiment DMN-L and sham-operated controls were injected intraperitoneally with glucose (1.36 g/kg body wt or 2.72 g/kg body wt) or saline after an overnight fast. Glucose loads, compared to saline injections, significantly depressed the controls' food consumption only during the first hour of refeeding. On the other hand, glucose injections did not depress food intake of the DMN-L rats. It is suggested that DMN lesions may have either destroyed glucoreceptors in the DMN that monitor glucose or the glucoprivation effects caused by 2DG and/or glucoreceptive pathways that pass through the DMN.

AbstractObjectivePortion sizes and bowl sizes may be related to food intake and perceived fullness. The objective of the present study was to investigate the effects of portion size and bowl size and possible interactions between these variables on food intake and fullness in a sample of Japanese men.DesignParticipants ate four different experimental meals across four weeks and completed questionnaires about their fullness using a visual analogue scale administered before and after meals. The four meal patterns included consistent portions of several foods commonly eaten together in typical Japanese meals, along with 150 g of rice served in a small rice bowl (diameter of 11·5 cm), 150 g of rice served in a large rice bowl (diameter of 13·5 cm), 250 g of rice served in a small rice bowl or 250 g of rice served in a large rice bowl.SettingTokyo.SubjectTwenty-one adult men participated in the study.ResultsPortion size had a significant main effect on rice intake (F(1,20)=83, P<0·001) and fullness (F(1,20)=8·0, P=0·010), but no significant effects of bowl size on the outcome variables were found. The interactions between portion size and bowl size on intake and fullness were not significant.ConclusionsThe sample of Japanese men showed an influence of portion size on food intake. Further research is needed to clarify the combined effects of bowl size and portion size on intake and fullness.

Background: New methods of dietary assessment are increasingly making use of online technologies. The development of a new online food frequency questionnaire warranted investigation of its feasibility and the reproducibility of its results. Objective: To investigate the feasibility and reproducibility of a newly developed online FFQ (WebFFQ). Design: The semiquantitative WebFFQ was designed to assess the habitual diet the previous year, with questions about frequency of intake and portion sizes. Estimations of portion sizes include both pictures and household measures, depending on the type of food in question. In two independent cross-sectional studies conducted in 2015 and 2016, adults were recruited by post following random selection from the general population. In the first study, participants (n = 229) filled in the WebFFQ and answered questions about its feasibility, and in two subsequent focus group meetings, participants (n = 9) discussed and gave feedback about the feasibility of the WebFFQ. In the second study, the WebFFQ’s reproducibility was assessed by asking participants (n = 164) to fill it in on two separate occasions, 12 weeks apart. Moreover, in the second study, participants were offered personal dietary feedback, a monetary gift certificate, or both, as incentives to complete the study. Results: In the feasibility study, evaluation form results showed that participants raised issues regarding the estimation of portion size and the intake of seasonal foods as being particularly challenging; furthermore, in the focus group discussions, personal feedback on diet was perceived to be a more motivating factor than monetary reward. In the reproducibility study, total food intake was lower in the second WebFFQ; however, 63% of the food groups were not significantly different from those in the first WebFFQ. Correlations of food intake ranged from 0.62 to 0.90, >86% of the participants were classified into the same or adjacent quartiles, and misclassification ranged from 0 to 3%. Average energy intake was 3.5% lower (p = 0.001), fiber showed the least difference at 1.6% (p = 0.007), and sugar intake differed the most at −6.8% (borderline significant, p = 0.08). Percentage energy obtained from macronutrients did not differ significantly between the first and second WebFFQs. Conclusion: Our results suggest that at group level, the WebFFQ showed good reproducibility for the estimations of intake of food groups, energy, and nutrients. The feasibility of the WebFFQ is good; however, revisions to further improve portion size estimations should be included in future versions. The WebFFQ is considered suitable for dietary assessments for healthy adults in the Norwegian population.

Food Conversion Efficiency

Mice of 2 strains were fed diets of natural ingredients in 3 different laboratories. The diets, which were fed before and after pelleting, contained levels of protein and energy within the ranges comparable to those found in existing laboratory diets and were the same formulation as those fed to rats in a previous paper. The diet with the lowest energy level supported the lowest rate of bodyweight gain, as it had with rats. Little effect was noticed on food consumption, conversion efficiency or water intake. Animals fed the pelleted diets gained bodyweight faster and there were indications of greater food and water consumption and also food conversion efficiency. It was concluded that food intake was improved with the pelleted diets resulting in the other increases.
