Knowledge, Perception and Consumption of Indigenous Foods in Gauteng Region, South Africa.

Urbanisation in South Africa has led to a nutritional transition from traditional diets (mainly based on indigenous foods) to a Western diet. Currently, the country is one of the most concerned about the prevalence of associated malnutrition and non-communicable diseases. One should, therefore, question the position of indigenous foods (IFs) in the population's eating habits since their nutritional and health value is known. This study aimed to collect updated data on South Africans' true awareness and consumption of indigenous foods, especially in the Gauteng region (the most urbanised province of the country). A quantitative cross-sectional research survey was conducted (n = 746). Among a list of 18 IFs, grain sorghum 32.4% (n = 242), marula 32% (n = 239), pearl millet 21.7% (n = 162), amadumbe 19.3% (n = 144) and cowpea 18.6% (n = 139) were the best known. However, the study noticed a maximum consumption of 19.3% (grain sorghum). Overall, this consumption was seasonal, and its level was significantly defined by race (p < 0.05). Black people consume more IFs compared to coloured people, Indian people and white people. Participants mostly consumed these foods for nutritional and health reasons and pointed out the problem of availability. "Poor image" was rated the lowest by all races (black 5.8%, coloured 4.2%, Indian 7.0% and white 4.1%) regarding the reasons for no or low consumption of IFs. Whatever the race, the desire to increase IF consumption was positive. The promotion of their integration into South African diets should, therefore, be considered as an intervention strategy.

Comparison of Effectiveness regarding a Culinary Medicine Elective for Medical Students in Germany Delivered Virtually versus In-Person.

(1) Background: The Culinary Medicine elective at the German medical schools of the universities of Göttingen, Giessen, and Brandenburg is a teaching kitchen-based elective aimed at training medical students on how to improve patient counselling on nutrition and lifestyle medicine topics. This curriculum was either delivered virtually (2021) or in-person (2022/2023). Changes in teaching effectiveness were evaluated. (2) Methods: The elective included seven modules in the teaching kitchen for 3 h each. It consisted of a short introduction and a hands-on interactive cooking part illustrating important dietary principles in different disease groups. The elective was conducted virtually in 2021 in a fully interactive setup using videoconference tools. Students in this cohort attended from their private kitchens whereas students in the in-person cohort (2022/2023) attended the same classes in the teaching kitchen. Standardized comparative self-assessment questionnaires on counselling competencies, nutrition knowledge, eating habits, and mental well-being (WHO-5) before and after the elective were used to determine teaching effectiveness. Paired and unpaired t-tests were performed to evaluate results. (3) Results: A total of 70 students (mean semester 6.3) were included in the virtual cohort, and 80 students (mean semester 6.3) were in the in-person cohort. In both, counselling competencies on 25 nutrition and lifestyle medicine topics increased significantly. Significant changes also occurred in most nutrition knowledge categories. Subjective well-being as well as personal attitudes towards nutrition counselling in medical practice improved significantly during the elective. Healthy eating habits improved in both groups as students ate significantly less unfavourable foods. There were no significant differences between the two groups apart from minor differences in nutrition knowledge. (4) Conclusions: The elective in Culinary Medicine improved students counselling competencies, nutrition knowledge, attitudes, well-being, and eating habits with no relevant difference between virtual and in-person teaching.

The Project "Colourful Means Healthy" as an Educational Measure for the Prevention of Diet-Related Diseases: Investigating the Impact of Nutrition Education for School-Aged Children on Their Nutritional Knowledge.

METHODS: An educational project called Cooking and Educational Workshops "Colourful means healthy" was conducted at the Department of Dietetics of the Faculty of Public Health in Bytom of the Medical University of Silesia in Katowice, Poland, between 1 July 2017 and 30 June 2019. The participants/recipients of the project were second-grade primary schoolchildren (317 pupils aged 7-9 years). OBJECTIVE: The aim of this article is to assess the change in knowledge of the principles of healthy eating among children aged 7-9 years following the nutritional education we carried out as part of the "Colourful means healthy" project. As part of project evaluation, the participating children were asked to rate selected food products in terms of their influence on human health (healthy vs. unhealthy). RESULTS: There was a statistically significant difference between the percentage of correct answers provided by the pupils before and after nutrition education. Thus, one may conclude that conducting an educational programme caused the participants' nutrition knowledge to increase. CONCLUSION: The present study demonstrated the potential of nutrition education in the form of cooking and educational workshops in terms of increasing nutrition knowledge. As such, workshops like these can be a useful measure for improving eating habits and eliminating dietary errors in the study population. However, future research is needed in order to verify whether such cooking and educational workshops can produce beneficial and lasting changes in dietary habits over the long term.

Lost in Communication: Do Family Physicians Provide Patients with Information on Preventing Diet-Related Diseases?

Diet-related diseases remain leading causes of death in most developed countries around the world. The aim of the study was to compare opinions of patients and family physicians on receiving and providing recommendations about physical activity, diet and use of medication. Methods: The questionnaire study was conducted among patients of 36 primary health care clinics in Poland between September 2018 and February 2019. Patients and physicians were interviewed separately by trained researchers. Data from 509 patients and 167 family doctors were analyzed. Results: The median age of patients was 44 years (interquartile range: 29-55) and 70% were women. The majority of physicians were women (59%) and the median age was 37 years (IQR: 31-50). There was a significant difference between physicians' declarations on providing recommendations on diet (92% vs. 39%) and activity (90% vs. 37%) versus patients' declarations on receiving them. Conclusions: The results indicate that there is significant room for improvement in providing patients with proper recommendations on diet and physical activity by their family physicians. Primary care physicians should put more emphasis on clear communication of recommendations on diet and physical activity.

Public Awareness of Diet-Related Diseases and Dietary Risk Factors: A 2022 Nationwide Cross-Sectional Survey among Adults in Poland.

A suboptimal diet is a risk factor for numerous non-communicable diseases. This study aimed to assess the level of knowledge on diet-related diseases and dietary risk factors among adults in Poland as well as to identify factors associated with awareness of diet-related diseases and dietary risk factors. This cross-sectional survey was carried out in July 2022 on a representative sample of adults in Poland. Data were received from 1070 individuals (53.3% females) aged 18−89 years. Out of eight diet-related diseases included in this study, overweight/obesity was the most recognized diet-related disease (85.0%). Stroke (26.2%) and osteoporosis (17.9%) were the least recognized diet-related diseases. Out of eight dietary risk factors included in this study, excessive consumption of sugar and salt (73.4%) was the most recognized dietary risk factor. Less than half of the respondents were aware that (1) too little vitamin intake, (2) too little intake of calcium and magnesium, (3) too little consumption of fish and oils, and (4) too little dietary fiber intake can lead to the development of the diseases. Having higher education and the presence of chronic diseases were the most important factors associated with a higher level of awareness of diet-related diseases and dietary risk factors (p < 0.05).

Edible Flowers as a Source of Dietary Fibre (Total, Insoluble and Soluble) as a Potential Athlete's Dietary Supplement.

Edible flowers have been gaining popularity among researchers, nutritionists and chefs all around the world. Nowadays, flowers are used to make food look and/or taste better; however, they are also a very good source of valuable nutrients (antioxidants, vitamins, proteins, fats, carbohydrates, macro and microelements). The aim of our study was to determine the content of dietary fibre and total protein in selected edible flowers; we also compared the nutritional content of petals, differentiating between the representatives of the Oleaceae and Asteraceae families, as well as herbaceous vs. woody plants. The study material consisted of petals of 12 edible flower species (Magnolia × soulangeana, Sambucus nigra L., Syringa vulgaris L. (white and violet flowers), Robinia pseudoacacia, Forsythia × intermedia, Cichorium intybus L., Bellis perennis, Tussilago farfara L., Taraxacum officinale F.H. Wiggers coll., Centaurea cyanus L., Calendula officinalis). Dietary fibre content was determined by the enzymatic-gravimetric method and ranged from 13.22 (Magnolia × soulangeana) to 62.33 (Calendula officinalis L.) g/100 g. For insoluble dietary fibre (IDF), the values ranged from 8.69 (Magnolia × soulangeana) to 57.54 (Calendula officinalis L.) g/100 g, and the content of soluble dietary fibre (SDF) was between 1.35 (Syringa vulgaris L.-white flowers) and 7.46 (Centaurea cyanus L) g/100 g. Flowers were also shown to be a good, though underappreciated, source of plant protein, with content ranging from 8.70 (Calendula officinalis L.) to 21.61 (Magnolia × soulangeana) g/100 g dry matter (Kjeldahl method). Considerable amounts of protein were found in the flowers of the olive family (Oleaceae) and woody plants, which can enrich the daily diet, especially vegan and vegetarian. Edible flowers of the Asteraceae family, especially the herbaceous representatives, contained high levels of both total dietary fibre and its insoluble fraction; therefore, they can be a rich source of these nutrients in the daily diet of athletes, which would perform a prebiotic function for gut bacteria.

Snacking patterns throughout the life span: potential implications on health.

Eating outside the three main meals - in other words, snacking - is a part of the dietary pattern of individuals in all stages of life. The quality and pattern of snacking have an impact on health during the life span. Thus, the aim of this review was to evaluate various patterns and health outcomes of the snacking habits of different demographical groups, from children to the elderly, throughout their life span. We discuss the snacking pattern among children and adolescents, which is characterized by consuming high energy foods with low nutrient value, and which is associated with increased risk of obesity. During university years, study stress and lack of time were obstacles to a healthy dietary pattern involving nutritious snacks, although awareness of the importance of healthy snacks was higher in this group than among younger age groups. Employment status and skipping regular meals were important factors affecting snacking quality and patterns in adulthood. Unhealthy snacks, high in energy, sugar, and salt and low in nutrients, were demonstrated to have a negative impact on individuals' health, such as oral health, blood pressure, obesity, and diabetes. In conclusion, encouraging individuals to consume healthy snacks that are high in nutrients through education to help them plan for their snacks is important to enhance health and reduce disease risk.

Redox Signaling and Advanced Glycation Endproducts (AGEs) in Diet-Related Diseases.

Diets are currently characterized by elevated sugar intake, mainly due to the increased consumption of processed sweetened foods and drinks during the last 40 years. Diet is the main source of advanced glycation endproducts (AGEs). These are toxic compounds formed during the Maillard reaction, which takes place both in vivo, in tissues and fluids under physiological conditions, favored by sugar intake, and ex vivo during food preparation such as baking, cooking, frying or storage. Protein glycation occurs slowly and continuously through life, driving AGE accumulation in tissues during aging. For this reason, AGEs have been proposed as a risk factor in the pathogenesis of diet-related diseases such as diabetes, insulin resistance, cardiovascular diseases, kidney injury, and age-related and neurodegenerative diseases. AGEs are associated with an increase in oxidative stress since they mediate the production of reactive oxygen species (ROS), increasing the intracellular levels of hydrogen peroxide (H2O2), superoxide (O2-), and nitric oxide (NO). The interaction of AGEs with the receptor for AGEs (RAGE) enhances oxidative stress through ROS production by NADPH oxidases inside the mitochondria. This affects mitochondrial function and ultimately influences cell metabolism under various pathological conditions. This short review will summarize all evidence that relates AGEs and ROS production, their relationship with diet-related diseases, as well as the latest research about the use of natural compounds with antioxidant properties to prevent the harmful effects of AGEs on health.

An exposé of the realpolitik of trade negotiations: implications for population nutrition.

OBJECTIVE: To explore the formal and informal ways in which different actors involved in shaping trade agreements pursue their interests and understand the interactions with nutrition, in order to improve coherence between trade and nutrition policy goals. DESIGN: The paper draws on empirical evidence from Australian key informant interviews that explore the underlying political dimensions of trade agreements that act as barriers or facilitators to getting nutrition objectives on trade agendas. SETTING: Countries experiencing greater availability and access to diets full of energy-dense and nutrient-poor foods through increased imports, greater foreign direct investment and increasing constraints on national health policy space as a result of trade agreements. PARTICIPANTS: Interviews took place with Australian government officials, industry, public-interest non-government organizations and academics. RESULTS: The analysis reveals the formal and informal mechanisms and structures that different policy actors use both inside and outside trade negotiations to pursue their interests. The analysis also identifies the discourses used by the different actors, as they attempt to influence trade agreements in ways that support or undermine nutrition-related goals. CONCLUSIONS: Moving forward requires policy makers, researchers and health advocates to use various strategies including: reframing the role of trade agreements to include health outcomes; reforming the process to allow greater access and voice to health arguments and stakeholders; establishing cross-government partners through accountable committees; and building circles of consensus and coalitions of sympathetic public-interest actors.
