Towards a More Sustainable Nutrition: Complementary Feeding and Early Taste Experiences as a Basis for Future Food Choices

Determining food choice motivations in Turkish adults: sustainable and healthy eating behavior, ecological footprint awareness, and food insecurity perspective

BACKGROUND

Revealing motivations in food choice and investigating the potential role of sustainable healthy eating behavior, ecological footprint awareness and food security in food choice are important points for a sustainable life. This study was conducted with 5285 adults aged 19-65 residing in Turkey to investigate their food choice motivations in terms of sustainable and healthy eating behavior, ecological footprint awareness, and the food insecurity perspective.

METHODS

In this context, the Food Choice Questionnaire, the Sustainable and Healthy Eating Behaviors Scale, the Awareness Scale for Reducing Ecological Footprint and the Household Food Insecurity Access Scale were used. Pearson correlation analysis was used to examine relationships between scales. The effects of sustainable and healthy eating behaviors, ecological footprint awareness, and household food insecurity on food choice motivations were examined via path analysis.

RESULTS

A moderate positive (r = 0.47, p < 0.05) relationship was found between the participants' awareness levels of sustainable and healthy eating behaviors and reducing the ecological footprint. A weak negative (r=-0.22, p < 0.05) relationship was found between their awareness levels of ecological footprint reduction and household food insecurity, and a weak negative (r=-0.16, p < 0.05) relationship was found between sustainable and healthy eating behaviors and household food insecurity. The explanatory power of ecological footprint awareness, sustainable and healthy eating behaviors, and household food insecurity for food choices was 27.2%. It was observed that ecological footprint awareness (β = 0.21, p < 0.05) and sustainable and healthy eating behaviors (β = 0.38, p < 0.05) significantly and positively affected food choices.

CONCLUSIONS

The variables influencing food choices the most were sustainable and healthy eating behavior, ecological footprint awareness, and household food insecurity. Although there are various data in the literature on the multiple factors that determine food choices, a consensus on the effectiveness of these factors has yet to be reached. A comprehensive examination of this issue, including all the components, is needed.

Dietary Approaches for Complementary Feeding: The Greek Mediterranean Diet as a Model for Caregivers

BACKGROUND/OBJECTIVES

Complementary feeding (CF), is defined as the process of providing foods in addition to milk when breast milk or milk formula alone are no longer adequate to meet nutritional requirements. CF affects not only growth but also the subsequent development of the child's dietary preferences. The Mediterranean diet (MedDiet) is one of the most studied dietary patterns worldwide. The main purpose of this article is to provide practical guidance for CF to caregivers introducing the Greek MedDiet, summarizing the current different approaches. The evidence-based information provided could be used by developers to create a reliable digital app for CF based on Mediterranean foods and traditional dishes.

METHODS

An in-depth literature review of the existing guidelines and recently published research data on CF using PubMed, national recommendations, and grey literature were undertaken.

RESULTS

Practical, simple, evidence-based, comprehensive tables are presented. The tables serve as a guide to simplify the process of introducing Mediterranean foods in CF. Τhe tables consist of a total of more than 90 foods and day-to-day guidance for the first 13 weeks of CF. Furthermore, specific dietary guidance and suggestions regarding the order and content of meals during CF are given.

DISCUSSION

The tables are based on updated recommendations, summarizing the optimal feeding practices in a MedDiet-based perspective.

CONCLUSIONS

Conclusively, there are significant contradictions among different organizations that present practical issues and cause confusion among caregivers. An effort was carried out to provide practical evidence-based guidance for caregivers introducing MedDiet during CF.

Eating Behaviors and Physical Activity versus the Big Five Personality Traits in Women with a Hereditary Predisposition to Breast or Ovarian Cancer

The Big Five personality traits-neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness-represent continuous, individual features that affect a number of vital health aspects, including morbidity, self-reported health status, or lifestyle. The aim of this study was to analyze the relationship between the eating behaviors and engagement in physical activity of women with a hereditary predisposition to breast or ovarian cancer and the Big Five personality traits. A total of 357 women, participants of 'The National Program for Families With Genetic/Familial High Risk for Cancer', were included in the study. In the healthy group, the following statistically significant predictors were found in variables: agreeableness-meal frequency (β = 0.151; p = 0.030); neuroticism-consumption of fruits and vegetables (β = -0.177; p = 0.016) and cereal products (β = -0.223; p = 0.002); openness to experience-consumption of plant-based fats (β = 0.141; p = 0.034) and physical activity (β = 0.153; p = 0.021). In the cancer group, the frequency of dairy consumption (β = 0.286; p = 0.003) and physical activity (β = 0.370; p = 0.000) were found to be statistically significant predictors for the openness to experience variable. Neuroticism is associated with less frequent consumption of fresh fruits and vegetables as well as cereal products. Openness to experience was more often linked with a higher frequency of dairy consumption, plant-based fats, and physical activity. Women with breast or ovarian cancer and a higher openness to experience consumed dairy and engaged in physical activity more often than their peers with the remaining personality traits.

Understanding the relationship between orofacial structures and feeding habits of preschoolers: A multivariate analysis

The understanding of the relationship between orofacial structures and feeding habits in preschoolers is helpful for health professionals and those dedicated to food science. The hypothesis tested was whether this relationship is already present even at a very young age. This cross-sectional study included 91 healthy caries-free children (50 girls/41 boys; 3.4-6.2 years; mean 4.1 years) and a comprehensive evaluation of the stomatognathic system was performed: dietary intake, facial and occlusal morphology, gustatory sensitivity, bite and lip forces, and orofacial myofunctional aspects (mastication, swallowing and breathing functions). Principal component analysis summarized the variables related to the form and function of the orofacial aspects; further, K-means analysis identified two clusters of participants with similar aspects. Cluster 1 ("Low orofacial myofunctional functioning"; n = 51) was characterized by children who showed the worst performance of mastication, swallowing and breathing functions and whose parents reported the consumption of sweets, cookies, chocolate, but not fresh fruits the day before, in addition to the higher bottle-feeding and pacifier use duration. This cluster also showed higher sweet taste threshold. Cluster 2 ("High orofacial myofunctional functioning"; n = 40) showed lower bottle-feeding and pacifier use duration, higher gustatory sensitivity, greater maxillo-mandibular dimensions, and better orofacial function performance. The variables sex and BMI did not associate to clusters profile. The frequencies of open bite and current sucking habit (pacifier) also differed between clusters. The results showed that an association between form and function of the structures that comprise the stomatognathic system and dietary intake is already present in children with primary dentition.

Interlinkages between Climate Change and Food Systems: The Impact on Child Malnutrition-Narrative Review

The pandemics of obesity, undernutrition, and climate change represent severe threats to child health. They co-occur; interact with each other to produce sequelae at biological, psychological, or social levels; and share common underlying drivers. In this paper, we review the key issues concerning child diet and nutritional status, focusing on the interactions with climate and food systems. Inadequate infant and young child feeding practices, food insecurity, poverty, and limited access to health services are the leading causes of malnutrition across generations. Food system industrialization and globalization lead to a double burden of malnutrition, whereby undernutrition (i.e., stunting, wasting, and deficiencies in micronutrients) coexists with overweight and obesity, as well as to harmful effects on climate. Climate change and the COVID-19 pandemic are worsening child malnutrition, impacting the main underlying causes (i.e., household food security, dietary diversity, nutrient quality, and access to maternal and child health), as well as the social, economic, and political factors determining food security and nutrition (livelihoods, income, infrastructure resources, and political context). Existing interventions have the potential to be further scaled-up to concurrently address undernutrition, overnutrition, and climate change by cross-cutting education, agriculture, food systems, and social safety nets. Several stakeholders must work co-operatively to improve global sustainable nutrition.

Making Healthy, Sustainable Diets Accessible and Achievable: A New Framework for Assessing the Nutrition, Environmental, and Equity Impacts of Packaged Foods

There is a growing global consensus among food system experts that diets and how we source our foods must change. The sustainable nutrition community continues exploring the environmental impact and dietary value of foods. Packaged foods have been largely ignored within the dialogue, and if they are addressed, existing frameworks tend to label them all as "ultraprocessed" and uniformly discourage their consumption. This approach lacks the nuance needed to holistically evaluate packaged foods within recommended dietary patterns. Additionally, there is considerable diversity of opinion within the literature on these topics, especially on how best to improve nutrition security in populations most at risk of diet-related chronic disease. In support of addressing these challenges, 8 sustainability and nutrition experts were convened by Clif Bar & Company for a facilitated discussion on the urgent need to drive adoption of healthy, sustainable diets; the crucial role that certain packaged foods can play in helping make such diets achievable and accessible; and the need for actionable guidance around how to recommend and choose packaged foods that consider human, societal, and planetary health. This article summarizes the meeting discussion, which informed the development of a proposed framework based on guiding principles for defining sustainable, nutritious packaged foods across key nutrition, environmental, economic, and sociocultural well-being indicators. Although additional research is needed to substantiate specific metrics in order to operationalize the framework, it is intended to be a foundation from which to build and refine as science and measurement capabilities advance, and an important step toward broader adoption of healthy, sustainable diets.

Considerations for the translation of nutrient recommendations as dietary plans for infants, children, and adolescents as reported in Italian Guidelines for healthy eating

Healthy eating in childhood and adolescence is important for proper growth and development and to establish a healthy foundation for future dietary habits. This paper aims to describe the elaboration of dietary plans for pediatric ages highlighting critical points related to the application of the Italian nutrient recommendations. National databases on food composition data were used to compile the dietary plans. Starting from the definition of serving size for adults, the suggested portion size for pediatric ages was shaped to produce appropriate dietary plans according to the different classes of age. Items from “cereals and derivatives,” “milk,” “fruit,” “vegetables,” “olive oil,” and “water” groups were included daily. Pizza was included once a week. Sweets and snacks were gradually introduced, once a week in infants and up to five times a week in adolescents. Legumes were provided three times a week, as a source of vegetable and sustainable proteins. The main critical aspect of the dietary plans was related to the monotony, especially for snacks and breakfasts. This work demonstrated the limits of the translation of Italian nutrient recommendations into dietary plans for pediatric age groups. Keeping the protein intake in the recommended range of 8–12% of daily energy resulted in inadequate provision of calcium and iron. Other critical points were the reference values for body weight and physical activity. The proposed dietary plans are adequate with regard to food composition, the intake of energy and several nutrients, and in terms of food selection. However, their implementations require action, information, and advocacy.

Mediterranean Diet in Developmental Age: A Narrative Review of Current Evidences and Research Gaps

Numerous studies in recent decades have shown that Mediterranean diet (MD) can reduce the risk of developing obesity in pediatric patients. The current narrative review summarizes recent evidence regarding the impact of MD across the different stages of child development, starting from fetal development, analyzing breastfeeding and weaning, through childhood up to adolescence, highlighting the gaps in knowledge for each age group. A literature search covering evidence published between 1 January 2000 and 1 March 2022 and concerning children only was conducted using multiple keywords and standardized terminology in PubMed database. A lack of scientific evidence about MD adherence concerns the age group undergoing weaning, thus between 6 months and one year of life. In the other age groups, adherence to MD and its beneficial effects in terms of obesity prevention has been extensively investigated, however, there are still few studies that correlate this dietary style with the incidence of non-communicable diseases. Furthermore, research on multi-intervention strategy should be implemented, especially regarding the role of education of children and families in taking up this healthy dietary style.

Health and Sustainable Nutritional Choices from Childhood: Dietary Pattern and Social Models

BACKGROUND

The role of diet in the pediatric age for optimal development, achievement, and maintenance of a healthy status is well recognized. Increasing attention is nowadays also paid to reducing the burden of human nutrition on the planet's health for present and future generations.

SUMMARY

Beyond environmental sustainability, the transition to diets rich in animal and processed foods contributes to an overall unhealthy nutritional status leading to an increased prevalence of obesity- and diet-related noncommunicable diseases. Childhood overweight and obesity are a growing public health crisis worldwide. The aim of this narrative review was to summarize evidence of the nutritional status and dietary habits in children and the link with environmental sustainability.

KEY MESSAGE

Optimizing nutrition in infancy and establishing healthy lifestyles from the preschool years might help to reduce the risk of overweight, and all the disorders related, respecting the sustainability dimension.

Dietary Patterns vs. Dietary Recommendations

Dietary Reference Values (DRVs) are important for developing labeling laws, identifying populations at risk of over- or under-consumption, and promoting public health interventions. However, the process of developing DRVs is quite complex, and they should not be viewed as recommendations ready to use or goals for individuals. Rather, they require interpretation by professionals and can form the basis of dietary advice. On the other hand, focusing on foods rather than macronutrients can assist individuals in understanding a healthy diet by taking into consideration many variables that may help compliance with a healthy dietary style. Evolution, tradition within specific geographical and historical contexts, taste, economic affordability, season-associated local dietary resources, and lifestyle may all explain the increasing popularity of dietary patterns that are highly successful today. Three models (the Mediterranean, New Nordic, and Japanese) have been recently characterized for geographical setting and food composition, as well as the associated lifestyle. Of note, all these three models rely on pyramids sharing a large basis made up of local vegetal resources and a top of red meats (allowed in many cases, but in limited amounts), thus allowing for the urgent demand of sustainability for the planet's health. This mini-review aimed to summarize the meaning of DRVs and to describe the dietary patterns that better contemplate health, diet diversity, and sustainability.

Lower Intake of Saturated Fatty Acids Is Associated with Improved Lipid Profile in a 6-Year-Old Nationally Representative Population

To strengthen the organization of new national dietary surveys and interventions in childhood, our aim was to study macronutrient intake and blood lipid profile at 6 years of age by comparing results from two earlier population-based cohorts. Subjects were n = 131 and n = 162 in the years 2001−2002 and 2011−2012, respectively. Three-day weighed food records were used to estimate diet and calculate nutrient intake. Total cholesterol, HDL-cholesterol and triacylglycerol were measured in serum and LDL-cholesterol was calculated. The average intake of saturated fatty acids (SFA) and trans FA was lower in 2011−2012 than 2001−2002 (13.3E% vs. 14.7E%, p < 0.001, and 0.8E% vs. 1.4E%, p < 0.001, respectively), replaced by a higher intake of unsaturated fatty acids. Total cholesterol and LDL-cholesterol were significantly lower in 2011−2012 than 2001−2002 (4.6 vs. 4.4 mmol/L, p = 0.003 and 2.8 vs. 2.5 mmol/L, p < 0.001, respectively). In a multiple linear regression model, one E% increase in SFA intake was related to a 0.03 mmol/L increase in LDL cholesterol (p = 0.04). A lower intake of saturated and trans fatty acids, replaced by unsaturated fatty acids, may have contributed to an improved lipid profile in a healthy 6-year-old population. Biological data for analysis of blood lipids are important in national dietary surveys in healthy children to monitor important health outcomes of interventions.
