A Short Dietary Assessment Instrument to Evaluate Protein Quality and the Diversity of Protein Sources in Malaysian Diets.

The diversity of protein food sources, animal and plant, may be a proxy measure of protein quality and adequate protein nutrition. A population-based sample of 1604 Malaysians aged ≥18 y completed one 24-h dietary recall and a new 29-item protein diversity indicator (PDI). Socio-demographic data were obtained by self-report. Mean total protein intakes were 75.2 g/d from 24-h recalls and 74.9 g/d from PDI. Protein diversity indicator-estimated protein intakes were 36.2% from meat and poultry, 8.8% from fish, 16.0% from eggs and dairy, and 39.0% from plants. Intakes of animal proteins varied with socioeconomic status and ethnicity and were associated with higher protein quality, defined as the adequacy of essential amino acids (EAAs) relative to protein requirements. Protein intakes and protein quality in Malaysia were generally adequate. Protein diversity indicator metrics can complement current methods of dietary assessment and may be useful for monitoring protein diversity and quality in other countries currently undergoing nutrition transition.

Breakfast Consumption and Quality of Macro- and Micronutrient Intake in Indonesia: A Study from the Indonesian Food Barometer.

Breakfast is an important meal that has been shown to have a positive effect on health. The current study aimed to assess the patterns of breakfast consumption among adult Indonesians and to estimate the contribution of breakfast to their nutrient intake and dietary quality. The study used 24-h recall data from the 2018 Indonesian Food Barometer study to assess breakfast intake among 1333 adults aged 18 and above from six provinces in Indonesia. Diet quality was measured using the Nutrient Rich Food index (NRF) 9.3, and the nutritional profile of breakfast was compared across tertiles of NRF 9.3. In total, 5.2% of adults in Indonesia skipped breakfast. Breakfast contributed 26% to daily energy intakes and 22-28% to intakes of all reported nutrients, except for total sugar (12%), vitamin C (8%) and vitamin D (7%). With respect to daily requirements, breakfast contributed approximately 20% to energy, protein, fat and sodium requirements, 26% to saturated fat but <15% to the requirements for most micronutrients and only 5% for fiber. Among breakfast consumers, a higher NRF score was associated with higher daily intakes of protein, dietary fiber and micronutrients and lower intakes of sodium from breakfast. This study suggests that a balanced breakfast in Indonesia should aim to lower fat and saturated fat intake while increasing fiber, potassium, calcium and vitamin C and D intake. These findings could inform the development of nutrient-based guidelines for breakfast consumption in Indonesia.

Breakfast Practices in Malaysia, Nutrient Intake and Diet Quality: A Study Based on the Malaysian Food Barometer.

Breakfast is often referred to as the "most important meal of the day" in shaping diet quality. This study established the patterns of breakfast consumption in Malaysia and assessed its contribution to the overall quality of the diet based on the 24 h recall data from the nationally representative and cross-sectional Malaysian Food Barometer (MFB, second data collection, 2018) to assess breakfast intake among adults (n = 1604). Diet quality was measured using the Nutrient Rich Food index (NRF) 9.3. The nutritional profile of breakfast was compared across tertiles of NRF 9.3. Overall, 89% of Malaysians consume breakfast. Breakfast was found to provide 474 kcal on average. The Malaysian daily diet was found to be rich in fats, saturated fats, total sugars, and sodium, with breakfast making a significant contribution to the daily intakes of these nutrients. Intakes of fiber, potassium, calcium, vitamins C and D, folate, iron, zinc, and magnesium were low. Breakfast was related to the overall diet quality measured by the NRF index. This study revealed that the breakfasts consumed by Malaysian adults were found to be nutritionally unbalanced. This analysis could serve as a basis for nutrient recommendations grounded in existing social and cultural breakfast patterns.

Food socialization of children with Prader-Willi syndrome: an interdisciplinary problematization.

Eating "disorders" of people with Prader-Willi syndrome are frequently reported in the biomedical literature. The eating behaviors are presented as a syndrome-specific trajectory over the course of a lifetime. Infants initially show anorexic behavior, which then develops into hyperphagia that lasts from childhood to adulthood and is characterized by strong cravings for food and relentless thinking about it. However, the sociocultural determinants of these food practices are not fully understood. In the first section of this article, we carry out a literature review of medical articles published on disordered eating in children with PWS. The second section draws on a social science perspective and offers an interdisciplinary problematization using the concept of food socialization. To conclude, the third section explores the challenges facing research and new questions that emerge from the alternative problematization that is the PWS Food Social Norms Internalization (FSNI) theory.

Eater-oriented knowledge framework for reducing salt and dietary sodium intake (scoping review).

Salt and dietary sodium are ubiquitously present in daily food practices and, at the same time, reducing salt intake presents an important public health issue. Given such an ambivalent position of salt in human diet, we argue that public health guidelines toward dietary sodium reduction require an eater-oriented knowledge framework. In this article we are making the first steps toward a flexible interdisciplinary database which would include nutritional, socio-economic, cultural, material, and socio-psychological determinants of salt consumption for comprehensive public health campaigns. We employ an explorative scoping review of academic articles and reports, limiting our review to the original data on salt or sodium consumption published in English or French between 2000 and 2022. We describe salt consumption as research object, identifying its representation in different research fields, data sources, methodologies, samples, and links with nutritional recommendations. We synthesize existing approaches via four eater-oriented categories: Socio-demographic and cultural descriptors of salt consumers; Knowledge, attitudes, and beliefs on nutritional norms; Salt practices associated with dietary or medical regimes; Salt materialities: interactions and contexts. In each category, we identify the dominant relational features, i.e., what kind of 'eater-salt' relation is being put forward. We thus build an interdisciplinary documentary base of dietary sodium consumption factors. We discuss the results, suggesting that comprehensive nutritional policies for global salt reduction require interdisciplinary eater-oriented data frameworks.

Diversity of protein food sources, protein adequacy and amino acid profiles in Indonesia diets: Socio-Cultural Research in Protein Transition (SCRiPT).

The ongoing nutrition transition in lower- and middle-income countries (LMIC) in South East Asia may have a positive impact on protein nutrition. This study assessed the diversity of plant and animal protein food sources in relation to essential amino acid (EAA) adequacy in a population-based sample (N 1665) in Indonesia. Dietary intakes from in-person 24 h recalls provided data on energy and protein intakes (in g/d) from plants (grains, legumes), meat, poultry and fish, and eggs and dairy. Protein diversity scores were based on the number of protein food sources over 24 h. EAA scores were the ratio of amino acid intakes to recommended values. Protein diversity and EAA scores were then compared across multiple socio-demographic indices. Analysis of variance and χ 2 tests were used to test for differences among groups. Energy intakes were 1678 kcal/d for men and 1435 kcal/d for women. Average protein intakes (and prevalence of inadequacy) were 59⋅4 g/d (41⋅7 %) for men and 51⋅5 g/d (51⋅1 %) for women. In regression analyses, higher protein diversity scores were associated with higher protein intakes, more animal protein and less plant protein and with higher EAA scores. Lower protein diversity scores were associated with lower intakes of lysine, leucine and valine relative to requirements, as well as with lower EAA, rural settings, less wealth and less modernisation. Greater diversity of animal protein food sources, observed among groups of higher socio-economic status, was linked to better amino acid adequacy and protein nutrition.

Animal and Plant Protein Food Sources in Indonesia Differ Across Socio-Demographic Groups: Socio-Cultural Research in Protein Transition in Indonesia and Malaysia.

BACKGROUND: Plant-based diets in lower-income countries are often associated with inadequate protein nutrition and adverse health outcomes. OBJECTIVE: To examine the diversity of protein food sources, in both animal and plant, across diverse socio-demographic groups in Indonesia as compared to Malaysia. DESIGN: The SCRiPT (Socio Cultural Research in Protein Transition) study was based on population-based samples recruited in Indonesia (N = 1665) and in Malaysia (N = 1604). Data from 24-h in-person dietary recalls in each country were used to construct the frequency counts of protein sources by food group. Protein sources were defined as fish, poultry, red meat (beef, pork, and mutton), eggs, dairy, and plants (cereals, pulses, and tubers). The percent reported frequencies for animal and plant proteins were compared across socio-demographic strata and by country. Analyses were based on one-way Anovas and general linear model regressions adjusting for covariates. RESULTS: Animal protein frequency counts were 34% of total in Indonesia, but 50% in Malaysia's. Higher reported consumption frequencies for poultry and red meat in both countries were associated with urban living, greater modernization, and higher socioeconomic status, with stronger social gradients observed in Indonesia. Reported fish consumption was higher in Indonesia than in Malaysia. Fish was more likely to be listed by rural island populations in Indonesia and was associated with lower education and incomes. Consumption frequencies for plant-based proteins were associated with lower socio-economic status in Indonesia and in Malaysia. CONCLUSIONS: More affluent groups in both countries reported higher frequencies for meat, eggs, and dairy as opposed to fish. Greater economic development in Southeast (SE) Asia is associated with more animal protein, particularly from poultry, which may displace fish, the traditional source of high quality protein for the region.

Disparities in the participation and adherence of older adults in lifestyle-based multidomain dementia prevention and the motivational role of perceived disease risk and intervention benefits: an observational ancillary study to a randomised controlled trial.

BACKGROUND: Preventive interventions for dementia are urgently needed and must be tested in randomised controlled trials (RCTs). Selection (volunteer) bias may limit efficacy, particularly in trials testing multidomain interventions and may also be indicative of disparities in intervention uptake in real-world settings. We identified factors associated with participation and adherence in a 3-year RCT of multidomain lifestyle intervention and/or omega-3 supplementation for prevention of cognitive decline and explored reasons for (non-) participation. METHODS: Ancillary study during recruitment and follow-up of the 3-year Multidomain Alzheimer Preventive Trial (MAPT) conducted in in 13 memory centres in France and Monaco, involving 1630 community-dwelling dementia-free individuals aged ≥ 70 who were pre-screened for MAPT (1270 participated in MAPT; 360 declined to participate). RESULTS: Response rates were 76% amongst MAPT participants and 53% amongst non-participants. Older individuals (odds ratio 0.94 [95% confidence interval 0.91-0.98] and those with higher anxiety (0.61 [0.47-0.79]) were less likely to participate in the trial. Those with higher income (4.42 [2.12-9.19]) and family history (1.60 [1.10-2.32]) or greater fear (1.73 [1.30-2.29]) of dementia were more likely to participate, as were those recruited via an intermediary (e.g. pension funds, local Alzheimer's associations, University of the 3rd Age, sports clubs) (2.15 [1.45-3.20]). MAPT participants living in larger towns (0.71 [0.55-0.92]) and with higher depressive symptoms (0.94 [0.90-0.99]) were less likely to adhere to the interventions. Greater perceived social support (1.21 [1.03-1.43]) and cognitive function (1.37 [1.13-1.67]) predicted better adherence. Descriptively, the most frequent reasons for accepting and refusing to participate were, respectively, altruism and logistical constraints, but underlying motivations mainly related to (lack of) perceived benefits. CONCLUSIONS: Disparities in uptake of health interventions persist in older age. Those most at risk of dementia may not participate in or adhere to preventive interventions. Barriers to implementing lifestyle changes for dementia prevention include lack of knowledge about potential benefits, lack of support networks, and (perceived) financial costs. TRIAL REGISTRATION: NCT00672685 (ClinicalTrials.gov).

Socio-Cultural and Economic Drivers of Plant and Animal Protein Consumption in Malaysia: The SCRiPT Study.

Countries in South East Asia are undergoing a nutrition transition, which typically involves a dietary shift from plant to animal proteins. To explore the main drivers of protein consumption, the SCRiPT (Socio Cultural Research in Protein Transition) study recruited a population sample in Malaysia (N = 1604). Participants completed in-person 24 h dietary recalls and socio-demographic surveys. Energy and nutrient intakes were estimated using Nutritionist Pro. A novel recipe-based frequency count coded protein sources as meat (chicken, beef, pork, and mutton), fish, eggs, dairy, and plants (cereals, pulses, tubers). Dietary intakes and frequencies were examined by gender, age, income, education, ethnicity, religion, and family status, using ANOVAs and general linear models. Energy intakes were 1869 kcal/d for men and 1699 kcal/d for women. Protein intakes were 78.5 g/d for men and 72.5 g/d for women. Higher energy and protein intakes were associated with Chinese ethnicity, higher education and incomes. Frequency counts identified plant proteins in 50% of foods, followed by meat (19%), fish (12%), eggs (12%), and dairy (7%). Most frequent source of meat was chicken (16%) rather than pork or beef (1.5% each). In bivariate analyses, animal protein counts were associated with younger age, higher education and incomes. In mutually adjusted multivariate regression models, animal proteins were associated with education and ethnicity; plant proteins were associated with ethnicity and religion. Protein choices in Malaysia involve socio-cultural as well as economic variables.

What Lies Behind the Transition From Plant-Based to Animal Protein?

Dietary changes that occur in response to economic development are collectively known as the nutrition transition. More specifically, diets built around staple cereals and tubers give way to diets with more animal products and more added sugars and fats. Although the proportion of dietary protein stays constant, plant proteins are replaced by animal proteins but in ways that are dependent on regional cultural, religious, and ethical concerns. The protein transition, viewed here as a subset of the broader nutrition transition, illustrates how dietary patterns in low- and middle-income countries are shaped by societal as well as by economic forces. The complexity of food decisions justifies the need to integrate nutrition with the social sciences in the study of evolving food systems.

Eating According to One's Genes? Exploring the French Public's Understanding of and Reactions to Personalized Nutrition.

In this article, we analyze qualitatively the understanding of and reactions to personalized nutrition (PN) among the French public. Focus groups were conducted to identify the opinions and discourses about two applications of knowledge from nutritional (epi)genomics: a biotechnology (nutrigenetic testing) and a public awareness campaign (the "first thousand days of life" initiative). Our objective was to understand to what extent PN could lead to changes in eating practices as well as in the representations of food-health relationships within France, a country characterized by a strong commitment to commensality and a certain "nutritional relativism." Although discourses on nutritional genomics testify to a resistance to food medicalization, nutritional epigenomics appears as more performative because it introduces the question of transgenerational transmission, thus parental responsibility.

[Socio-anthropological perspective of the under nutrition care of cancer patients]. / Perspective socio-anthropologique de la prise en charge de la dénutrition du malade cancéreux.

The diet of the cancer patient is a major focus of prevention and treatment strategy of the recent plans that fight against cancer. It is sometimes reduced to a rapid series of more or less general advice, often interfered by other sources of information, more or less conventional. In this pathological situation where the nutritional status of the patient is paramount, it seems crucial to understand the different modalities of how the food behavior is implemented. This article describes the construction modalities of the cancer eater decisions. The goal of the socio-anthropological analysis proposed in this article is to initiate a reflection on the under nutrition problem by focusing on the approach of the eater diagnosed with cancer. The aim is to help identify ways of action to fight against under nutrition and improve the quality of life of the patient.

Influence of social factors on weight-related behaviors according to gender in the French adult population.

Although the prevalence of obesity is higher in low socioeconomic position (SEP), the relationship between SEP and body mass index (BMI) differs according to gender. The purpose of this study is to investigate the relationships between BMI and SEP according to gender and explore the weight-related behaviors. In a cross-sectional survey, 1646 French adults were weighed and answered a questionnaire about eating behavior (DEBQ), SEP markers, ideal weight perception, physical activity and smoking. Our study showed that BMI was inversely correlated with SEP score in women only, independently of other BMI-associated factors (age, restrained eating, smoking status, TV viewing and physical activity). The SEP gradient was the same in both genders for some weight-related behaviors, such as restrained eating, physical activity and TV viewing, but differs for others, such as smoking and weight consciousness. There was an interaction between the SEP score and the actual BMI on the ideal BMI in women only, thus the difference in ideal body weight according to SEP is mainly due to difference in obese women. Our study concluded that gender differences in the relationship between BMI and SEP could be mainly due to the subjects' perception of weight appropriateness and their weight-related behaviors.

Reflexões metodológicas para o estudo das práticas alimentares / Methodological approaches on the studies of food practices

A alimentação humana, envolvendo aspectos psicológicos, fisiológicos e socioculturais, é um fenômeno de grande complexidade e, em assim sendo, o estudo das práticas alimentares tem suscitado o desenvolvimento de instrumentos e métodos no interior de várias disciplinas. Neste artigo, que apresenta a alimentação humana sob abordagem da Sociologia e da Antropologia, definem-se as diferentes dimensões do espaço social alimentar, desde o registro do consumo alimentar até os processos de diferenciação social envolvendo as formas de cozinhar, as formas de consumir e a temporalidade. Analisam-se os diferentes tipos de dados que podem ser utilizados, tomando-se o cuidado de distinguir os dados comportamentais (que podem ser obtidos tanto pela observação quanto pela declaração) dos dados de representação. Apresentam-se, em seguida, os diferentes instrumentos de coleta e as vias de entrada no fenômeno alimentar. Esses instrumentos metodológicos, construídos no interior de um quadro teórico-sociológico, são propostos aos pesquisadores da área, objetivando a construção de uma possível visão comum, que proporcione uma abordagem pluridisciplinar do fato alimentar.

O espaço social alimentar: um instrumento para o estudo dos modelos alimentares / Food social space: a tool to study food patterns

Pensar a alimentação a partir das Ciências Sociais supõe a superação de certos obstáculos epistemológicos que baseiam as posições teóricas da fundação dessa disciplina: o positivismo e a autonomia do social. O conceito de espaço social proposto por Georges Condominas para compreender as inter-relações entre um grupamento humano e o seu meio encontra na alimentação um campo de aplicação particularmente fecundo. Assim, propõe-se o conceito de "espaço social alimentar" como um instrumento de estudo dos modelos alimentares, assinalando a conexão bioantropológica de um grupamento humano ao seu meio. Nele destacam-se seis dimensões principais que focalizam espaços e sistemas diversos: o comestível, a produção alimentar, o culinário, os hábitos de consumo alimentar, a temporalidade e as diferenciações sociais. Um modelo alimentar é uma configuração particular do espaço social alimentar.
