RESUMO

The school meal system could contribute to the transition towards more sustainable food system by promoting plant-based meals. Knowing whether parents want more vegetarian school meals for their children is a prerequisite for a successful implementation. The present study aimed to estimate the proportion of parents who would opt for more vegetarian school meals for their children and to study associations of willingness with family characteristics and food choice motives. An online survey was sent to parents whose children are registered for school canteen in Dijon (France). We collected child-level information, data on family sociodemographic characteristics, and data on dietary habits and food choice motives of the family. We examined family characteristics associated with the willingness to increase the frequency of vegetarian school meals from one meal per week to two or daily. Generalized linear models were performed. In total, 49% of parents were willing to opt for a second weekly vegetarian meal and 26% for a daily vegetarian meal for their children (n = 1261). Parents willing to opt for more vegetarian meal were more likely to have higher education, be flexitarian or vegetarian and to currently opt for pork-free meals for their children, and their children attended the school canteen less frequently. Environmental motives were positively associated with the willing to opt for a second weekly vegetarian meal; familiarity and sensory appeal motives were negatively associated. Health and animal welfare motives were positively associated with the willing to opt for a daily vegetarian meal and sensory appeal was negatively associated. Increasing the frequency of vegetarian school meals would satisfy a demand expressed by parents but must be accompanied by interventions enhancing pleasure of eating vegetarian meals.

RESUMO

In Western countries, a behavioural shift towards more plant-based diets is helpful in protecting population and planet health. School canteens are an important public policy target to achieve this transition. Increasing the frequency of vegetarian meals in school canteens has been proposed as a solution to decrease greenhouse gas emissions while maintaining a good nutritional quality. However, vegetarian meals acceptance by children is key to limit unintended consequences such as increased food waste or increased nutritional inequalities. We aimed to examine children's liking for vegetarian and non-vegetarian main dishes at school canteens; and whether it varied across socioeconomic level. Connected scoring devices displaying a five-point smiley scale were installed in all the 38 primary school canteens of a French city, located in socially diverse neighbourhoods. Every day after their school lunch, children were asked to rate the main dish they had just eaten. During one school year, from September 2021 to June 2022, we collected 208,985 votes for 125 main dishes, including 32 vegetarian (i.e., no meat or fish) and 93 non-vegetarian dishes, for an average of 1672 (SD 440) votes per day across the 38 school canteens. We showed no difference in children's liking for vegetarian and non-vegetarian dishes. Additionally, the socioeconomic level of the schools was found to interact negatively with children's liking for vegetarian main dishes whereby vegetarian main dishes tended to be more liked in schools of lower socioeconomic level. In this French city, children's acceptance would not be a barrier to increase the frequency of vegetarian school meals and would not increase social dietary inequalities.

RESUMO

Although encouraging the shift toward sustainable diets in young adults is a major challenge to preserve population and planet health, the precursors of sustainable diets in this population remain unknown. This study aimed to identify the behavioural determinants of healthier and more environmentally friendly diets among university students. A sample of 582 French university students reported their food consumption using an online 125-item food frequency questionnaire. The nutritional quality (adherence to French recommendations, sPNNS-GS2) and the greenhouse gas emissions (GHGE) of students' diets were calculated for an isocaloric diet. Behavioural determinants were measured based on a literature review and classified into the Capability, Opportunity, Motivation Behaviour (COM-B) framework. Linear models, adjusted for socioeconomic characteristics, were run to identify the most prominent behavioural predictors of nutritional quality and GHGE of students' diets. Higher cooking skills (ß = 0.38, p = 0.01) and health motives (ß = 0.91, p < 0.001) were associated with higher nutritional quality. Greater environmental knowledge was linked to lower GHGE (ß = -0.07, p = 0.002), while health and weight control motives were associated with higher GHGE (ß = 0.26, p = 0.02 and ß = 0.39, p < 0.001). Enhancing cooking skills and environmental knowledge could enable healthy and environmentally friendly diets, but health-based motives can act as a lever and as a barrier.

RESUMO

Infant formulas (IFs), the sole adequate substitute to human milk, undergo several thermal treatments during production that can damage milk proteins and promote the formation of Maillard reaction products, modifying nutritional and sensory properties. The aim of this study was to determine the impact of a minimally processing route based on membrane filtration associated with different levels of heat treatment, on the odor, taste, texture and color attributes of IFs, then to compare with those of commercial milks. Three experimental IFs (produced with membrane filtration associated with low - T-, medium - T+, or high thermal treatments - T+++) were evaluated. Triangular tests conducted with a panel of 50 adults highlighted clear disparities between all the IFs. The same panel applied the Check-All-That-Apply method to evaluate the IFs: the range of variability between T- and T+++ was similar to that between the 2 commercial IFs, and the sensory characteristics of the experimental IFs were not far from the commercial brands for flavor and texture attributes. Analysis performed on the citation frequencies for each descriptor differentiated T-/T+ from T+++, but all the experimental IFs were described with positive sensory characteristics, unlike one commercial IF. Volatile organic compounds (VOCs) content of IFs with low and high thermal treatments were analyzed. Forty VOCs were identified by gas chromatography-mass spectrometry. T- contained a higher quantity of VOCs than T+++, except for benzaldehyde (Maillard reaction product), and aldehydes (oxidation-related products) were the most represented compounds. In conclusion, the processing was associated with sensory differences among IFs, but no marked difference in flavors was found according to CATA and physicochemical analysis. Additionally, no unpleasant sensory descriptors were noted. This shows that the minimally processed route leads to IFs that could fit well within the market from a sensory point of view.

RESUMO

BACKGROUND: Food systems highly contribute to anthropogenic greenhouse gas emissions and shifting towards more environmentally friendly diets is urgently needed. Enabling consumers to compare the environmental impact of food products at point-of-purchase with front-of-pack labelling could be a promising strategy to trigger more environmentally friendly food choices. This strategy remained to be tested. METHODS: The effect of a new traffic-light front-of-pack environmental label on food choices was tested in a 2-arm randomised controlled trial in a virtual reality supermarket. Participants (n = 132) chose food products to compose two main meals for an everyday meal scenario and for an environmentally friendly meal scenario with or without the label. The environmental label (ranging from A: green/lowest impact, to E: red/highest impact) was based on the Environmental Footprint (EF) single score calculation across food categories. The effect of the label on the environmental impact of food choices in each scenario was tested using linear mixed models. RESULTS: In the everyday meal scenario, the environmental impact of meals was lower in the label condition than in the no label condition (-0.17 ± 0.07 mPt/kg, p = 0.012). This reduction was observed at no nutritional, financial nor hedonic cost. The effectiveness of the label can be attributed to a change in the food categories chosen: less meat-based and more vegetarian meals were chosen with the label. In the environmentally friendly meal scenario, we demonstrated that the label provided new information to the participants as they were able to further reduce the environmental impact of their food choices with the label (-0.19 ± 0.07 mPt/kg, p = 0.005). CONCLUSIONS: Implementing a front-of-pack environmental label on food products in real supermarkets could increase awareness of the environmental impact of food and contribute to drive more environmentally friendly food choices. TRIAL REGISTRATION: The study protocol was pre-registered prior to data collection at Clinicaltrials.gov (NCT04909372).

RESUMO

While breast-feeding is the recommended feeding mode in infancy, rates are low in some Western societies, and infants are widely fed formula. France, in particular, shows high rates of infant formula use, including formulas with protein hydrolysates. The degree of protein hydrolysis has previously been associated with neurodevelopmental outcomes. The present study examines the associations between the protein's hydrolysis degree in infant formula and child neurodevelopment up to 3·5 years of age in the French nationwide Étude Longitudinale Française depuis l'Enfance (ELFE study). Parents reported on brand and name of the formula used at 2 months, and protein hydrolysis degree was derived from the ingredient list. Analyses were based on 6979 infants (92·2, 6·8 and 1 % consuming non-hydrolysed, partially and extensively hydrolysed formulas, respectively). Neurodevelopment was assessed at age 1 and 3·5 years with the Child Development Inventory (CDI), at age 2 years with the MacArthur-Bates Communicative Development Inventories and at age 3·5 years with the Picture Similarities sub-scale (British Ability Scales). Associations between protein hydrolysis degree and child neurodevelopment were assessed using linear and logistic regression for overall scores and poor CDI sub-domain scores (<25th centile), respectively. Among formula-fed infants, protein hydrolysis degree in infant formula was not associated with overall neurodevelopmental scores up to 3·5 years. Some associations were found with the motor skills CDI sub-domain, but they were not consistent at 1 and 3·5 years as well as across sensitivity analyses. The use of hydrolysed formula appears safe in terms of overall neurodevelopment, and research should further investigate specific neurodevelopmental domains.

RESUMO

Infants become increasingly exposed to sweet-tasting foods in their first year of life. However, it is still unclear whether repeated exposure to sweet taste is linked to infants' sweetness liking during this period. Making use of data from the OPALINE cohort, this study aimed to examine the link between sweetness exposure and sweetness liking during two important periods in early infant feeding: at the start of complementary feeding (3-6 months) and the transition to the family table (10-12 months). Infants' sweetness exposure was assessed using 7-d food records which were completed by mothers every month (n 312), reporting daily consumption rates of formula/breast milk or complementary food and the type of formula milk and/or complementary foods for each feeding occasion. Infants' sweetness liking was studied in the laboratory at 3, 6 and 12 months of age by assessing their response to a lactose-water solution and the amount drunk of this solution compared with plain water. Linear regressions and structural equation model assessed associations between exposure to and liking for sweetness at 6 and 12 months. Neither at 6 (n 182) nor at 12 months (n 197) was sweetness exposure associated with sweetness liking. While sweetness liking at 3 months was unrelated to liking at 6 months, the latter predicted sweetness liking at 12 months. These findings demonstrate no association between sweetness exposure at 3 to 12 months and liking at 6 and 12 months despite a sharp increase in sweetness exposure in that period. However, sweetness liking at 6 and 12 months was positively associated.

RESUMO

OBJECTIVE: As part of an update of feeding benchmarks targeting children aged 0-3 years, this study aimed to explore parental perceptions, information-seeking practices and needs concerning infant and young child feeding (IYCF) to design an efficient communication strategy. DESIGN: Participants were recruited using the quota sampling to complete an online survey. Effects of parity, child age, prematurity, parental education and financial situation on parents' responses were evaluated separately. SETTING: France. PARTICIPANTS: A nationally representative sample of 1001 parents of children <4 years. RESULTS: Parents whose child had any medical condition affecting feeding (children with medical condition (CMC), 17 %) were considered separately from healthy children's parents. All the healthy children's parents recognised the importance of IYCF for children's health and growth; however, one-third considered the available advice contradictory and not guilt-free. The most used information sources were healthcare professionals (HCP, 81 %), internet (72 %) and parental networks (63 %). The most influential sources (mean influence ± sd) included HCP (7·7 ± 1·7/10), childcare professionals (7·3 ± 1·8/10) and parental networks (6·9 ± 1·8/10). Parents searched for practical tips for implementing IYCF starting when their child was 5 months old. Differences regarding the type of source used by parents with higher v. lower educations were small. Search strategies differed according to parity or child age but not to prematurity. The CMC parents reported slightly different practices and needs. CONCLUSIONS: Parents receive information from multiple sources, which can lead to confusion when deciding which advice to follow. A public health communication strategy adapted to the current parental needs should target these various sources.

RESUMO

BACKGROUND: Parents are crucial in establishing their children's eating habits, and doctors and health/childcare professionals (HCCPs) can provide meaningful and trusted guidance on feeding, especially in the 0-3-year-old period. With the upcoming release of the official brochure containing the new child feeding recommendations in France, this study aims to: (1) assess professionals' practices and perceptions regarding their communication with parents on child feeding and (2) evaluate their perception of the draft of the new brochure. METHODS: A 15-page draft brochure (without pictures) containing updated child feeding recommendations for children 0-3 years old was developed by Santé publique France (the French public health agency). Online semi-structured interviews were conducted with professionals (n = 21), including 13 pediatricians and general practitioners (doctors) and eight healthcare or childcare professionals (HCCPs) two weeks after they were provided with this draft brochure to read. The interview guide was developed and piloted with other professionals (n = 3) prior to these interviews. Interview data were transcribed verbatim and analyzed thematically using an inductive approach. RESULTS: While doctors and HCCPs mostly communicate orally with parents, both acknowledged that the brochure might be a helpful supplement, especially for HCCPs to legitimize their advice to parents. For doctors, giving the brochure to parents may help provide systematic advice and save time during consultations. Professionals serving parents of lower socioeconomic status would prefer a supplement with less text and more illustrations. In general, the messages were perceived to be easily understandable but providing detachable cards to distribute according to the child's age would facilitate information dissemination and might be more useful to parents. Professionals reported that lack of training, the circulation of contradictory information, and language barriers were common challenges. CONCLUSION: French professionals welcomed the new official brochure as a means to spread updated child feeding recommendations. However, this brochure could be modified and specific tools developed to better adapt to professionals' needs of communication with parents and to facilitate the relay of information. Providing updated and consistent information to parents should be considered a priority for public health stakeholders toward increased adherence to new recommendations.

RESUMO

Organic food consumption and its effects on health remain understudied in adults and in children. The aim of this study was to describe family characteristics associated with feeding infants organic foods during the complementary feeding period. The analysis included 9764 children from the French Étude Longitudinale Française depuis l'Enfance (ELFE) birth cohort. In addition to telephone interviews conducted at 2, 12 and 24 months, a monthly questionnaire about milk feeding and complementary foods (including organic foods) was completed by parents between 3 and 10 months. Associations between family characteristics and feeding with organic foods during complementary feeding were analysed by multivariable multinomial logistic regression. Overall, 51 % of infants never consumed organic food during the complementary feeding period (up to 10 months), 24 % sometimes, 15 % often and 9 % always or almost always. As compared with infants never fed organic foods, those 'often' or 'always' fed organic foods were born to older mothers, with higher education level or family income, and lower pre-pregnancy BMI. As compared with never-smoking women, women who had stopped smoking before pregnancy were more likely to feed their infant organic foods. Feeding with organic foods was also related to long breast-feeding duration and later introduction to complementary foods. To conclude, associations between feeding with organic foods and family socio-economic position as well as infant feeding practices need to be considered when studying the impact of organic foods on children's health and development.

RESUMO

To limit the transmission of COVID-19, nationwide lockdown was imposed in France between March, 17th and May 10th, 2020. This disruption in individuals' daily routines likely altered food consumption habits. We examined how changes in food choice motives related to changes in nutritional quality during the lockdown compared to before. A convenience sample of 938 French adults completed online questionnaires on the Qualtrics platform at the end of April 2020. Participants were retrospectively asked about their food choice motives and food consumption during the month before and in the first month of the lockdown. The importance of nine food choice motives was assessed: health, convenience, sensory appeal, natural content, ethical concern, weight control, mood, familiarity, and price, scoring from 1 to 4. Food intakes were recorded using a food frequency questionnaire including 110 foods, 12 non-alcoholic beverages and 4 alcoholic beverages. Adherence to the French dietary recommendations before and during the lockdown was estimated using the simplified PNNS-GS2, scoring from -17 to 11.5. The nutritional quality of diet was lower during the lockdown compared to before (-0.32, SD 2.28, p < 0.001). Food choice motives significantly changed and an increase in the importance of weight control was associated with increased nutritional quality (ß = 0.89, p < 0.001, partial η2 = 0.032), whereas an increase in the importance of mood was associated with decreased nutritional quality (ß = -0.43, p = 0.021, partial η2 = 0.006). The lockdown period in France was related to a decrease in nutritional quality of diet on average, which could be partly explained by changes in food choice motives. The lockdown was indeed related to modification of food choice motives, notably with an increase of mood as a food choice motive for 48% of the participants, but also with an increase of health (26%), ethical concern (21%) and natural content (19%) suggesting a growing awareness of the importance of sustainable food choices in some participants.

RESUMO

Sleep problems reported by parents affect 20% to 30% of infants. Few studies focused on the longitudinal association between infant feeding practices and sleep, especially in France. Analyses were based on 8,696 infants from the French national birth cohort ELFE. Collection of feeding practices from birth to 10 months allowed for the identification of trajectories of use of baby cereals and thickened formula by group-based trajectory modelling and calculation of duration of any breastfeeding (BF) and age at complementary feeding introduction (CFI) excluding baby cereals. Total sleep duration (TSD), night waking (NW) and sleep onset difficulties (SOD) were reported at age 1. Associations between feeding and sleep were tested by multinomial logistic regressions. BF duration ≥6 months was associated with parent-reported frequent NW, SOD and TSD ≤ 12 h/24 h at age 1. For TSD and SOD, this association was no longer significant after accounting for parental sleep-related practices. Early use of baby cereals (≤5 months) was associated with poor sleep. Early CFI (<4 months) was associated with shorter TSD and SOD but not NW. Early use of thickened formula (only <6 months) was related to poor sleep at age 1 (NW and SOD), whereas late (around 6 months) use of thickened formula was associated with better sleep. BF duration ≥6 months was related to poor sleep at age 1 but not after adjustment on 1-year parental sleep-related practices except for NW. The use of baby cereals or early CFI was not related to better sleep at age 1.

RESUMO

BACKGROUND: Large portion sizes encourage overconsumption. Prior studies suggest that this may be due to errors in anticipating the effects of portion size, although the studies were limited to adults and energy-dense foods. OBJECTIVE: Our aim was to investigate potential anticipation errors related to the effects of portion size on hunger, eating enjoyment, and healthiness ratings among 8-to-11-year-old children, for snacks differing in energy density and healthiness perception, and as a function of initial hunger. METHODS: In a within-subject design, 83 children aged 8 to 11 years old were first asked to anticipate how much they would enjoy, how hungry they would feel after eating, and how healthy it would be to eat a recommended serving size, a 50% larger portion, and a 125% larger portion of brownie or applesauce. Over six subsequent sessions, the children were asked to eat all of each of these portions and then rate their post-intake enjoyment, residual hunger, and healthiness perceptions. We also measured hunger at the beginning of each session. RESULTS: For both snacks, larger portions reduced anticipated and experienced residual hunger similarly. In contrast, larger portions increased anticipated but not experienced eating enjoyment for both snacks; although larger portions increased anticipated and experienced enjoyment ratings among extremely hungry children. All children under-anticipated how much they would enjoy the smaller portion sizes. Healthiness ratings were unaffected by portion size for both snacks but differed across foods (applesauce vs. brownie). CONCLUSIONS: Children anticipate the effects of portion size on hunger change accurately, overestimate the effects of portion size on eating enjoyment, and rate food healthiness on food type and not portion size. Helping children better anticipate the enjoyment from smaller (recommended) portion sizes and understand that food quantity, not just quality, matters for healthy eating may be a solution to improve portion control.

RESUMO

Food sensory imagery - creating a vivid mental image of the sensory experience of eating - can lead to the selection of smaller portions because it serves as a reminder that eating enjoyment does not necessarily increase with portion size. The evidence is mostly limited to adults and to energy-dense foods for which it is particularly difficult to predict the satiating effects of consumption quantity. The objective was to study how food sensory imagery influences portion size selection of foods varying in energy density (brownie and applesauce) by 7- to 11-year-old children. During after-school time, 171 children were randomized into two conditions. Children in the food sensory imagery condition were asked to imagine the taste, smell, and texture of eating palatable foods, i.e., chocolate cereal, chocolate waffle, and chocolate candies. Children in the control condition performed a similar sensory imagery task for non-food-related activities. Children were then asked to choose between the recommended serving size, a 50% larger portion, and a 125% larger portion of either brownie or applesauce. One week later, they were placed in the same condition for the other food. Compared to the control condition, food sensory imagery led children to choose 7.1% less brownie but had no effect on applesauce portion selection. Exploratory findings showed that the food sensory imagery intervention was especially effective at reducing brownie portion size selection among children who were moderately hungry, who usually eat fast, and whose parents pressure them to eat. In conclusion, food sensory imagery may be a useful intervention to nudge children towards healthier portion size choices because it reduces the selected portion size of an energy-dense snack without reducing the selected portion size of a healthier snack.

RESUMO

There is some evidence of specific oro-detection of FFAs in rodents and humans. The aim of this study was to record gustatory evoked potentials (GEPs) in response to FFA solutions and to compare GEPs in response to linoleic acid solution with GEPs obtained after stimulation with sweet and salty tastants. Eighteen healthy men were randomly stimulated with fatty (linoleic acid), sweet (sucrose), and salty (NaCl) solutions at two concentrations in the first experiment. Control recordings (n = 14) were obtained during stimulation by a paraffin oil mixture without FFA or by water. In the second experiment, 28 men were randomly stimulated with five FFA solutions and a paraffin emulsion. GEPs were recorded with electroencephalographic electrodes at Cz, Fz, and Pz. GEPs were observed in response to FFA in all participants. GEP characteristics did not differ according to the quality and the concentration of the solutions in the first experiment and according to the FFA in the second experiment. This study describes for the first time GEPs in response to FFA and demonstrates that the presence of FFA in the mouth triggers an activation of the gustatory cortex. These data reinforce the concept that fat taste could be the sixth primary taste.

RESUMO

BACKGROUND: The effect of exposure to microorganisms on allergic diseases has been well studied. The protective effect of early food diversity against allergic diseases was previously shown in the PASTURE cohort study. The consumption of cheese, a food potentially rich in microbial diversity, deserves further examination. We aimed to evaluate whether cheese consumption is associated with allergic diseases. METHODS: In the PASTURE study (birth cohort in 5 European countries), data on feeding practices, environmental factors, and allergic diseases were collected by questionnaires from birth to 6 years (N = 931). Cheese consumption at 18 months of age was quantified in terms of frequency and diversity (ie, number of consumed types among 6 types: hard pressed, semipressed, soft, blue, fresh cheese, and cheese from the farm). Multiple logistic regressions were performed to evaluate the effect of cheese consumption on atopic dermatitis (AD), food allergy (FA), allergic rhinitis, asthma, and atopic sensitization at 6 years after adjustment for confounders of atopy. RESULTS: Cheese consumption (vs. nonconsumption) had a significant protective effect on AD (OR = 0.51 [0.29-0.90], P = 0.02) and FA (OR = 0.32, [0.15-0.71], P = 0.004), but no effect on atopic sensitization, allergic rhinitis, and asthma at 6 years. This effect on AD and FA may be related to the diversity of consumed cheeses (OR = 0.64 [0.48-0.85] per cheese type, P = 0.002; OR = 0.55 [0.33-0.92], P = 0.02, respectively). CONCLUSION: Although reverse causality cannot totally be ruled out, cheese diversity at 18 months had a protective effect against AD and FA at 6 years in addition to the protective effect of diversity of other foods.

RESUMO

PURPOSE OF REVIEW: The current review focuses on studies investigating the factors related to the development of preferences for foods and sensory inputs (tastes, odours, and food textures) in the first years of life, which constitutes a specific window for food learning. RECENT FINDINGS: Foetal nutrition, intrauterine growth, and prematurity influence food preferences; this topic warrants more research to broaden our understanding of the 1000 days phenomenon. Although it is less studied than other sensory inputs, food texture acceptance, and the related sensitive period for texture introduction are attracting more attention, as is the impact of fat acceptance. Research should focus not on vegetables alone but on diverse foods whose consumption is encouraged (e.g., fishes and legumes). The role of parental feeding practices, as another major determinant, continues to inspire research exploring the bidirectional influences between children and caregivers. New interventions have confirmed the strong positive influence of repeated exposure to foods through familiarization via taste lessons, cooking, or play activities on acceptance. Interventions that consider individuals traits are necessary. SUMMARY: Although new evidence is available, it remains a challenge to consider both individual traits and bidirectional influences between parents and children and to investigate this issue worldwide and in all socioeconomic status groups.

RESUMO

The relationship between eating a healthy diet and positive health outcomes is well known; nurturing healthy eating among children therefore has the potential to improve public health. A healthy diet occurs when one's usual eating patterns include adequate nutrient intake and sufficient, but not excessive, energy intake to meet the energy needs of the individual. However, many parents struggle to establish healthy eating patterns in their children due to the pressures of modern life. Moreover, healthcare providers often do not have the time or the guidance they need to empower parents to establish healthy eating practices in their children. Based on existing evidence from epidemiologic and intervention research, the Nurturing Children's Healthy Eating collaboration, established by Danone Institute International, has identified four key themes that encourage and support healthy eating practices among children in the modern Western world. The first - positive parental feeding - explores how parenting practices and styles, such as avoiding food restriction, allowing children to make their own food choices, and encouraging children to self-limit their portion sizes, can influence children's dietary intake. The second - eating together - highlights the link between eating socialization through regular family meals and healthful diet among children. The third - a healthy home food environment - explores the impact on eating practices of family resources, food availability/accessibility, parental modeling, and cues for eating. The fourth - the pleasure of eating - associates children's healthy eating with pleasure through repeated exposure to healthful foods, enjoyable social meals, and enhancement of the cognitive qualities (e.g. thoughts or ideas) of healthful foods. This paper reviews the evidence leading to the characterization of these nurturing themes, and ways in which recommendations might be implemented in the home.

RESUMO

Previous studies have shown a high level of noncompliance with recommendations on breastfeeding duration, especially in France. The objective was to describe the association between breastfeeding initiation and duration and the statutory duration of postnatal maternity leave, the gap between the end of legal maternity leave and the mother's return to work, and maternal working time during the first year post-partum. Analyses were based on 8,009 infants from the French nationwide ELFE cohort. We assessed the association with breastfeeding initiation by using logistic regression and, among breastfeeding women, with categories of breastfeeding duration by using multinomial logistic regression. Among primiparous women, both postponing return to work for at least 3 weeks after statutory postnatal maternity leave (as compared with returning to work at the end of the statutory period) and working less than full-time at 1 year post-partum (as compared with full-time) were related to higher prevalence of breastfeeding initiation. Among women giving birth to their first or second child, postponing the return to work until at least 15 weeks was related to a higher prevalence of long breastfeeding duration (at least 6 months) as compared with intermediate duration (3 to <6 months). Working part-time was also positively related to breastfeeding duration. Among women giving birth to their third child or more, working characteristics were less strongly related to breastfeeding duration. These results support extending maternity leave or working time arrangements to encourage initiation and longer duration of breastfeeding.

RESUMO

This report summarises a workshop convened by ILSI Europe on 3 and 4 April 2017 to discuss the issue of dietary sweetness. The objectives were to understand the roles of sweetness in the diet, establish whether exposure to sweetness affects diet quality and energy intake, and consider whether sweetness per se affects health. Although there may be evidence for tracking of intake of some sweet components of the diet through childhood, evidence for tracking of whole diet sweetness, or through other stages of maturity are lacking. The evidence to date does not support adverse effects of sweetness on diet quality or energy intake, except where sweet food choices increase intake of free sugars. There is some evidence for improvements in diet quality and reduced energy intake where sweetness without calories replaces sweetness with calories. There is a need to understand the physiological and metabolic relevance of sweet taste receptors on the tongue, in the gut and elsewhere in the body, as well as possible differentiation in the effects of sustained consumption of individual sweeteners. Despite a plethora of studies, there is no consistent evidence for an association of sweetness sensitivity/preference with obesity or type 2 diabetes. A multifaceted integrated approach, characterising nutritive and sensory aspects of the whole diet or dietary patterns, may be more valuable in providing contextual insight. The outcomes of the workshop could be used as a scientific basis to inform the expert community and create more useful dialogue among health care professionals.
