Behavioral nutrition

Over the past century, dietary recommendations emphasizing food patterns as means to deliver essential nutrients have garnered widespread acceptance. The necessity for foods supplying vital nutrients and energy throughout various life stages requires the involvement of local resources and cultural practices to prevent nutrient deficiency diseases. Since the 1980s, dietary guidelines aimed at adverting chronic diseases have relied on epidemiological research to predict which dietary patterns correlate with reduced risk of chronic disease or links to health outcomes...

Encapsulation technologies have achieved encouraging results improving the stability, bioaccessibility and absorption of bioactive compounds post-consumption. There is a bulk of published research on the gastrointestinal behavior of encapsulated bioactive food materials alone using in vitro and in vivo digestion models, but an aspect often overlooked is the impact of the food structure, which is much more complex to unravel and still not well understood. This review focuses on discussing the recent findings in the application of encapsulated bioactive components in fabricated food matrices...

Eating in the absence of hunger (EAH) has been associated with overweight and obesity during childhood. The gold standard to assess this behavior is a laboratory-based protocol, but a questionnaire to assess EAH more efficiently in children and adolescents has been developed and validated in English. We assessed construct validity (structural and convergent validity) and reliability (internal consistency and temporal stability) of a French translation of the EAH Questionnaire for Children and Adolescents among French-Canadian youths...

Introduction. Dietary quality involves both the quantity and quality of food offered, the way and the setting in which it is offered, and the responses of the person offering it. The objective of this study was to identify behavioral patterns related to responsive feeding in children aged 6 to 23 months in urban areas from Argentina in 2018-2019. Population and methods. Secondary analysis based on data from the second National Survey on Nutrition and Health of 2018-2019 conducted in a multistage probability sample from urban areas of 5000 inhabitants or more in Argentina...

Essential minerals are cofactors for synthesis of neurotransmitters supporting cognition and mood. An 8-week fully-blind RCT of multinutrients for ADHD demonstrated three times as many children (age 6-12) had significantly improved behavior ("treatment responders") on multinutrients (54%) compared to placebo (18%). The aim of this secondary study was to evaluate changes in fasted plasma and urinary mineral concentrations following the intervention, and their role as mediators and moderators of treatment response...

OBJECTIVE: To investigate whether inflammatory indices, including the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), product of platelet and neutrophil count (PPN), and lymphocyte-to-monocyte ratio (LMR), correlate with chronic obstructive pulmonary disease (COPD). METHODS: This was a cross-sectional study from the National Health and Nutrition Examination Survey (NHANES) database 2007-2018. The SII, NLR, PLR, PPN and LMR were calculated based on blood cell counts and were log2-transformed...

The availability of soil water content and nutrition in the maternal plant environment plays pivotal roles in shaping the performance, physio-biochemical properties, and chemical composition of the produced seed. This study aimed to investigate the effects of water and arbuscular mycorrhizal fungi (AMF) of maternal plant environment on performance, physio-biochemical properties, and chemical compositions of Lallemantia species offspring. A split-factorial experiment was performed using a randomized complete block design (RCBD) with three replications...

Intensive multidisciplinary intervention is increasingly recognized as the standard of care for children with complex feeding problems. Much, however, remains unknown about this treatment model. This current qualitative, prospective study sought to identify intensive multidisciplinary day hospital programs operating in the US, describe the treatment approach, and summarize current capacity.

BACKGROUND: The way in which children interact with food has a profound impact on their health and wellbeing. However, most research, strategy and policy where food is the focus are derived from adult perspectives. There is limited understanding of children's perspectives of the nature of their everyday food practices, and their level of involvement and influence. This work garnered children's (8-12 years old) descriptions of, and involvement in, their everyday food practices. METHODS: Forty-two children from 28 families from across Brisbane (Australia) participated in qualitative creative draw-and-tell interviews and 20 of these children (from 15 families) also completed Photovoice data collection...

Norway´s population of older, first-generation immigrants is expected to almost triple by the year 2060 due to decreased mortality and continued immigration. Studies indicate that older immigrants in Norway have a higher rate of non-communicable disease than older non-immigrants. Eating a health-supporting diet is important for reducing disease risk and maintaining independence in older adults. The purpose of this study was to increase understanding of the eating preferences and behaviors of older, home-dwelling, first-generation immigrants in Oslo, and to identify influences on their eating preferences and behaviors...

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...

Primary objectives were to examine: 1) changes in movement behaviours (i.e., outdoor play (OP), organized physical activity (PA), screen time (ST), sleep) across the first two years of COVID-19 among Canadian toddlers and preschoolers, and 2) intrapersonal, interpersonal, community, and policy moderators of change in movement behaviors. Participants were 341 Canadian parents of children (start of study: 1-4 years; 48% female). Participants completed online questionnaires regarding their children's movement behaviours and intrapersonal, interpersonal, and community factors at five time-points before and throughout the pandemic (T1-T5)...

Pancreatic ductal adenocarcinoma (PDAC) presents a formidable clinical challenge due to its intricate microenvironment characterized by desmoplasia and complex tumor-stroma interactions. Conventional models hinder studying cellular crosstalk for therapeutic development. To recapitulate key features of PDAC masses, this study creates a novel sea-and-island PDAC tumor construct (s&i PTC). The s&i PTC consists of 3D-printed islands of human PDAC cells positioned within an interstitial extracellular matrix (ECM) populated by human cancer-associated fibroblasts (CAFs)...

BACKGROUND: Fathers play a pivotal role in parenting and child feeding, but they remain underrepresented in intervention studies, especially those focused on disadvantaged populations. A better understanding of fathers' experiences and needs regarding support access and child nutrition information in the context of disadvantage can inform future interventions engaging fathers. OBJECTIVE: This study aims to explore fathers' experiences; perceived enablers; and barriers to accessing support and information related to parenting, child feeding, and nutrition and to co-design principles for tailoring child nutrition interventions to engage fathers...

The feasibility of defatted grape seed powder (DGSP) stabilizing Pickering emulsion gels as butter substitute was investigated. The Pickering emulsion gel was constructed using DGSP through high-speed homogenization, and the effects of particle concentration ( c ) and oil-phase (Medium chain triglyceride) volume fraction ( φ ) on its structure and properties were investigated. Its application as a butter substitute was also evaluated. The results showed that DGSP had various particle shapes, a wide particle size distribution (3-130 μm), and a three-phase contact angle of 128...

Bone nonunion is a common and serious orthopedic disorder, the occurrence of which is associated with a disruption of the dynamic balance between osteoblasts and osteoclasts during bone repair. However, the critical molecular mechanisms affecting this homeostasis are not well understood, and it is essential to investigate the specific components of this mechanism and to restore the balance between osteoblasts and osteoclasts to promote bone repair. First, we defined this complex local environmental factor as the "bone nonunion microenvironment" and identified the importance of the "struggle" between osteoblasts and osteoclasts, which is the most essential element in determining the process of repair ...
