Current State of Archaeobotanical Research in Ghana: On Diet, Food Resources and Research Perspectives

This review delves into the changes in food consumption patterns over time in West Africa, emphasising the significant role played by archaeobotanical studies. West African food consumption has been influenced by various factors such as economic, environmental, and external influences. Our initial studies focused on plant and animal domestication and the spread of grains. The arrival of Europeans in the 15th century brought changes in foodways, introducing new crops from the New and Old World. Some misconceptions about African food and agriculture have been challenged, accentuating the region’s diversity and resilience. The paper discusses the initial focus on economic factors and the domestication of plants, leading to a better understanding of the connection between food and society. Additionally, it dispels misapprehensions about West African cuisine and highlights the impact of the Atlantic trade on foodways. The study underscores the significance of interdisciplinary research in rectifying any biases surrounding Africa’s food history. Archaeobotanical research has shed light on the dynamic nature of African foodways, including the integration of American crops into local food traditions. However, knowledge of the extent of adoption and use of these crops during the precolonial era remains limited. More research is required to comprehend the adoption of American crops and the resilience of African food systems.

Chemical Analysis of Kitchen Waste for Developing Formulae for Compost Fertilizer

The rapid growth of the global population and changes in food consumption patterns have resulted in issues relating to food insecurity. Improved strategic solutions are needed to allow easy access to food and also to manage large volumes of waste efficiently. From this research, a microeconomic- level solution to manage the aforementioned issues is addressed. Common kitchen waste such as peels and discarded parts of fruits and vegetables can be combined to produce compost fertilizer. Producing compost fertilizer in this manner can be considered a microeconomic-level waste management strategy. Compost fertilizer produced using kitchen waste can subsequently be used in home gardening. Many vegetables and fruits can easily be cultivated in small, confined spaces such as in home gardens. This study analyzed chemical parameters such as total carbon and other total nutrient levels (N, P, Ca, Mg and K) in ten kitchen waste and two supplementary samples using standard methods. The kitchen waste samples consisted of peels and discarded parts of fruits and vegetables. The two supplementary samples- Tithonia diversifolia (Wild sunflower), and Gliricidia sepium were chosen because they are nutrient-rich organic fertilizers. The analysis results were then fed to a computer program developed for this study. It was based on the simulated annealing algorithm. The program generated different formulae for producing 100 g mixtures of raw materials for composting, by mixing the 10 kitchen waste and 2 supplementary samples in 24 different combinations. The nutrient levels of these mixtures were expected to match or exceed a calculated ―target nutrient level‖. It was calculated based on local compost fertilizer standards and the chemical analysis results. The target nutrient level calculated as the minimum required level by dry mass of each material was 25.00% Carbon, 1.25% Nitrogen, 0.63% Phosphorus, 1.25% Potassium, 0.88% Calcium, and 0.63% Magnesium. The program was able to generate mixtures of raw materials in which most of the levels matched or exceeded the target level. However, the phosphorus levels of all formulae fell below the target phosphorus level and in some mixtures, the magnesium level also was less than the targeted level. The actual nutrient level of one of the 100 g mixtures (combination C3) containing 0.19 g banana stem, 0.21 g discarded tea grounds, 0.41 g discarded scraped coconut, 0.57 g banana peel, and 97.34 g Gliricidia leaves was (% by dry mass), 85.68% Carbon, 2.20% Nitrogen, 0.25% Phosphorus, 1.32% Potassium, 2.24% Calcium and 0.71% Magnesium. This promising method can further be developed by adding more nutrient-rich raw materials to the program. The program could be a useful tool for compost fertilizer manufacturing, especially for small-scale horticultural purposes.

Call for emergency action to restore dietary diversity and protect global food systems in times of COVID-19 and beyond: Results from a cross-sectional study in 38 countries

BackgroundThe COVID-19 pandemic has revealed the fragility of the global food system, sending shockwaves across countries' societies and economy. This has presented formidable challenges to sustaining a healthy and resilient lifestyle. The objective of this study is to examine the food consumption patterns and assess diet diversity indicators, primarily focusing on the food consumption score (FCS), among households in 38 countries both before and during the first wave of the COVID-19 pandemic. MethodsA cross-sectional study with 37 207 participants (mean age: 36.70 ± 14.79, with 77 % women) was conducted in 38 countries through an online survey administered between April and June 2020. The study utilized a pre-tested food frequency questionnaire to explore food consumption patterns both before and during the COVID-19 periods. Additionally, the study computed Food Consumption Score (FCS) as a proxy indicator for assessing the dietary diversity of households. FindingsThis quantification of global, regional and national dietary diversity across 38 countries showed an increment in the consumption of all food groups but a drop in the intake of vegetables and in the dietary diversity. The household's food consumption scores indicating dietary diversity varied across regions. It decreased in the Middle East and North Africa (MENA) countries, including Lebanon (p < 0.001) and increased in the Gulf Cooperation Council countries including Bahrain (p = 0.003), Egypt (p < 0.001) and United Arab Emirates (p = 0.013). A decline in the household's dietary diversity was observed in Australia (p < 0.001), in South Africa including Uganda (p < 0.001), in Europe including Belgium (p < 0.001), Denmark (p = 0.002), Finland (p < 0.001) and Netherland (p = 0.027) and in South America including Ecuador (p < 0.001), Brazil (p < 0.001), Mexico (p < 0.0001) and Peru (p < 0.001). Middle and older ages [OR = 1.2; 95 % CI = [1.125–1.426] [OR = 2.5; 95 % CI = [1.951–3.064], being a woman [OR = 1.2; 95 % CI = [1.117–1.367], having a high education (p < 0.001), and showing amelioration in food-related behaviors [OR = 1.4; 95 % CI = [1.292–1.709] were all linked to having a higher dietary diversity. ConclusionThe minor to moderate changes in food consumption patterns observed across the 38 countries within relatively short time frames could become lasting, leading to a significant and prolonged reduction in dietary diversity, as demonstrated by our findings.

Food Purchasing Pattern in Rural Family of Haryana State, India

India experienced a massive change in food consumption patterns. There has been a decline in cereal, especially coarse cereal intake whereas consumption of other food items (fruits, vegetables, meat products and milk products) has slightly increased particularly in rural Haryana. These changes vary across socio-economic groups, which have implications for intergroup inequalities. This paper attempts to show food consumption patterns across selected social and economic groups and identifies food consumption regions in India. This paper shows that the food purchasing pattern of farm families revealed that vegetables (other than leafy) were highly purchased food items, with an average quantity of 14.7 kg per month. Therefore, there is a need to make them aware of different consumer laws.

Exploring Consumer Perceptions and Changing Consumption Patterns for Smoked Paprika: Implications for Traditional Food Products in Spain.

Changes in the level of income of the population and a reduction in time availability are shifting food consumption from traditional to more convenient food products. The production of traditional food has a significantly positive impact on the territory, as it contributes to preserving cultural traditions and identity and supports rural development and resilience, thus becoming essential for the survival of rural areas. Within traditional food products, spices are among the most usual ingredients in traditional cuisine, extensively used to add flavour and colour to dishes. However, spices in general and paprika in particular-one of the most typical spices in the Spanish cuisine and the subject of this paper-have been rarely the subject of scientific studies. The purpose of this study is to analyse consumers' perceptions towards paprika and determine the level of its consumption. For this purpose, a survey was conducted on a representative sample of Spanish consumers. The findings indicated that the average consumption of paprika was 154.5 gr/person per year. Although the general consumers' perceptions toward this spice were generally positive, they proved to be less positive amongst young people and inhabitants of large cities, whose consumption of the spice was also lower. Additionally, the Pimentón de La Vera PDO paprika was the most popular version of paprika, being mentioned by all the participants. The findings from this study confirm the change in food consumption patterns.

Preferences of Food Consumption - Local Food vs Organic Food

Objective: The purpose of this research is to understand the change in food consumption patterns of consumers of organic food especially after the pandemic. Theoretical framework: This study draws suggestions from attitude-behaviour relationship model. The internal factors are - attitudes towards local food, and attitudes towards supporting the local economy, while the external factors are - high price and trust issues related to organic food. Method: Data from organic food consumers was quantitatively analysed using multiple regression in SPSS. A seven point Likert scale was considered to measure the responses and a Cronbach alpha score of 0.8 indicated that the constructs were reliable. Results and conclusion: The findings suggest organic food consumers who have an attitude towards local food consumption and an attitude to support local economy have positive intention towards local food purchase. Also the high price and trust issues related to organic food positively influence the intention to purchase local food. Implications of the research: This study uncovers the changes in food consumption pattern during and after the pandemic. COVID-19 has affected people financially too and affordability has become a key. Marketers will have to come up with affordable solutions to market healthy food. Originality/value: The shift in consumers' preference from organic to local has implications for the environment and the society. Local food is found to be sustainable, healthy and less expensive. Local food systems cater to food traceability and high food safety.

THE IMPACT OF INCREASING COOKING OIL PRICES ON FOOD CONSUMPTION PATTERNS IN VARIOUS HOUSEHOLD INCOME GROUPS IN ACEH PROVINCE

Consumption of cooking oil from year to year continues to increase, especially in Aceh Province. In general, almost all people in this area consume cooking oil derived from oil palm plants for household needs. As one of the basic needs, the increase in the price of cooking oil has affected changes in household consumption patterns. This study aims to analyze the impact of rising cooking oil prices on changes in people's food consumption patterns in various household income groups in a quantitative descriptive manner. The results of the analysis show that the increase in the price of cooking oil has an impact on changes in food consumption patterns, namely a decrease in consumption of several food needs other than cooking oil. This decline occurred in various household income groups in Aceh Province.

Increasing Nitrogen Losses Due to Changing Food Consumption Patterns in Bayannur City, China

Increasing urbanization and affluence have led to changes in food consumption patterns. The application of nitrogen (N) fertilizers ensures food security but also leads to environmental pollution due to N losses, through processes such as acidification, eutrophication, and greenhouse gas emissions. To clarify whether changes in food consumption patterns could increase N losses and to explore sustainable food system pathways, this study integrated the Chinese Food System Dashboard and the Nutrient Flows in Food Chains, Environment and Resources Use model to quantify and compare the link between food consumption and N losses in different agricultural regions using a case study of Bayannur City in the Yellow River Basin from 2000 to 2016. During the study period, Bayannur's food consumption pattern changed from a "high carbohydrate and pork pattern" to a "high fiber and herbivore pattern", which represents a shift from low to high N consumption. The per-capita food consumption decreased by 11.55% from 425.41 kg cap-1, whereas the per-capita N losses increased by 12.42% from 35.60 kg N cap-1. The average share of the plant-oriented and animal-oriented food supply in these losses was 53.39% and 46.61%, respectively. There were differences in the food consumption patterns and N losses in Bayannur's farming, farming-pastoral, and pastoral regions. The changes in N losses were most significant in the pastoral region. The N losses to the environment increased sharply by 112.33% from 22.75 g N cap-1 over the past 16 years. The low level of economic development in Bayannur resulted in a shift in the food consumption pattern to a high N consumption. Four measures to protect food security and reduce the food N cost were proposed: (1) increasing the wheat planting area and maintaining the existing corn one; (2) expanding the scale of high-quality alfalfa planting; (3) enhancing the area of oat grass and wheat replanting; and (4) using modern planting technology.

Indigenous Foods in Decline? A Study on Changing Consumption Patterns Within the Barolong Boo Ratshidi Community, Northwest Province of South Africa

ABSTRACT This study examines changes in food consumption patterns within African communities, with specific reference to the Barolong Boo Ratshidi community in the Northwest Province of South Africa. The study uses a qualitative approach through in-depth interviews conducted with members of this community (or participants) to understand their views of food and consumption patterns. It also sought to understand the participants’ understanding of the factors behind these changes and their effects as well as their understanding of the meanings underlying indigenous African foods. It was found that contrary to the widely held view that only the elderly members of communities are endeared to indigenous foods, this is not so because the youth also express preference for these foods while embracing changes that have effect on their consumption. This is so even though many of the youth are ignorant of the cultural meanings of indigenous African foods served on different occasions. Their enthusiasm for these foods is seen as an optimistic basis for future efforts meant to revitalize them.

Determinants of Changes in the Diet Quality of Japanese Adults during the Coronavirus Disease 2019 Pandemic

This study evaluated changes in diet quality during the coronavirus disease 2019 (COVID-19) pandemic and its association with variations in attitudes or behavior, as well as health status changes. Participants were Japanese adults aged 20-69 years who resided in 13 prefectures where specific cautions were announced to prevent the spread of the virus. An online survey was conducted in September 2021, and participants were those who shopped for food or prepared meals more than twice a week during the survey. Overall, 2101 participants were analyzed. An improved or worsened diet quality was determined based on changes in food consumption patterns, and participants were categorized into three groups (improved diet quality (IDQ), worsened diet quality (WDQ), and others). The IDQ group participants (10.2%) improved their dietary consciousness during COVID-19, cooked almost everything from ingredients, and increased their balanced meal eating frequency. However, the WDQ participants (11.1%) had worsened dietary consciousness and increased consumption of takeaway meals and alcohol but decreased balanced meal consumption. Cooking frequency changes were not independent determinants of variations in diet quality. Our results show that the diet quality changes during COVID-19 were possibly caused by changes in dietary consciousness or different levels of meal preparation practices.

Food security in a changing climate world

The purpose of this article is to analyze the potential impact of climate change on food security. Global environmental changes coupled with socio-economic changes are a major food security issue and challenge. The main findings show that all four key elements of food security, namely availability, stability, use and access are significantly affected by changes in the environment. The most vulnerable segment of the population is those whose living conditions and livelihoods are strictly dependent on climate change and their ability to adapt is the lowest due to household income. This category includes children and women, poor people, the elderly and all those who depend on agriculture, animal husbandry, fishing and other natural resources. Climate change and its impact on demographic patterns, urbanization, population movements, and changes in food consumption patterns are intensifying food system risks globally.

A Playful Approach to Household Sustainability: Results From a Pilot Study on Resource Consumption

Background. U.S. households produce a significant amount of greenhouse gas emissions, indicating a potential to reduce their carbon footprints from changing food, energy, and water (FEW) consumption patterns. Behavioral change to FEW consumption is needed, but difficult to achieve. Interactive and engaging approaches like serious games could be a way to increase awareness of possible measures, leading to more sustainable behavior at a household level. This study looks into the experiences and effects of a digital game for homeowners with the potential to reduce FEW resource consumption impacts. Intervention. In this study, we developed and implemented a digital game to explore its potential to raise awareness of the consumption and conservation of FEW resources and the efficacy of conservation messages. This study aims to measure learning outcomes from game participation and to assess the suitability of the game for informing resource conservation actions. Methods. We tested a proof-of-concept of a digital four-player game, called HomeRUN, with 28 homeowners. The data collected include homeowners’ values and preferences with regard to FEW resources. The patterns of game actions are analyzed with an emphasis on the effectiveness of conservation messaging in informing household consumption behavior. Results. About 65% of the respondents agree that they gained a better understanding of the greenhouse gas emission impacts of FEW resource consumption after playing the game. Over 57% of the respondents agree that the game experience would influence their future consumption behavior, while a quarter of the respondents are unsure. Overall, we demonstrate the HomeRUN game has potential as a tool for informing conservation efforts at a household level.

Mapping research trends on food supply chain: a bibliometric analysis

PurposeThe purpose of the paper is to present research trends in the food supply chain in the context of changes in food systems due to globalization, urbanization, environmental concerns, technological changes and changes in food consumption patterns in the world.Design/methodology/approachThe present investigation was performed by bibliometric analysis using the VOSviewer software, visualization software developed by Nees and Waltman (2020). In this work we performed co-citation, bibliographic coupling and keyword evolution analyses.FindingsThe results show that research in the food supply chain is rapidly changing and growing. By applying co-citation analysis, The authors found that the intellectual structure of the food supply chain has evolved around six clusters, namely, (a) collaboration and integration in the supply chain (b) sustainable supply chain management, (c) food supply chain management (FSCM), (d) models for decision-making in the food supply chain, (e) risk management in the supply chain and (g) quality and food logistics in the supply chain. However, based on bibliographic coupling analysis, The authors find that new or emerging research niches are moving toward food supply market access, innovation and technology, food waste management and halal FSCM. Nevertheless, the authors found that the existing research in each of the thematic clusters is not exhaustive.Research limitations/implicationsThe limitation of the research is that the analysis mainly relates only to the bibliometric approach and only one database, namely, Scopus. Broader inclusion of databases and deeper application of content analysis could expand the results of this research.Originality/valueThere are limited studies that have examined research trends in food supply chains in both developed and developing countries using bibliometric analysis. The present investigation is novel in identifying the thematic research clusters in the food supply chain, emerging issues and likely future research directions. This is important given the dynamics, consumer demand for quality food, technological changes and environmental sustainability issues in food systems.

Online ordering and delivery of ready-to-eat foods in Ghana: a call for policy towards ensuring food safety in the service

Changes in food consumption patterns have resulted in the high demand and patronage of online food ordering and delivery services in Ghana. The attention of every individual involved in the food chain is needed to ensure food safety. Since a food delivery service and person are introduced in online food ordering and delivery services, new and unique food safety challenges and concerns are created. This paper hence investigates the food safety concerns and challenges posed by online food ordering and delivery services and further provide solutions to tackle and improve food safety in the service. Additional concerns raised by food ordering and delivery services include an absence of food transport or delivery regulation in Ghana, a lack of food safety education and training for food delivery persons as well as food fraud actions like mislabeling and substitution. To boost food safety in online food ordering and delivery services, the service should be regulated by the Ghana FDA with policies and manuals that address these food safety concerns. Food meant for delivery should be packaged well to prevent contact with insects and other contaminants. Timely delivery should be a priority to make sure delivered foods are still in the right and safe temperatures for consumption.

Dissecting Supplement and Nutrients Intake of Adults with and without COVID-19 History through the Lens of Health Belief Model.

Over the past two years, the world has faced the pandemic, COVID-19, and various changes. Several regulations and recommendations from the Ministry of Health of Indonesia have contributed to behavioral changes among Indonesian residents, especially in food consumption patterns. The change in food consumption patterns can be a positive change that formed due to the COVID-19 pandemic. This study aimed to examine whether the application of a Health Belief Model (HBM)-based nutrition education programme can be effectively used in changing the beliefs of adults with or without a COVID-19 history in supplement and nutrient intake. This study was a cross-sectional study involving 140 adults. This study placed 70 adults with/without a COVID-19 history into the intervention group. The intervention group participated in a nutrition education programme. The respondents were asked to fill out the questionnaire. The data were analyzed by independent and paired t-tests and Chi-square test. The result of this study showed no association between perceived susceptibility, severity, benefit, barrier, and self-efficacy, of nutrient and supplement intake with the history of COVID-19 among the respondents. However, most of the respondents in this study were low in their scores of perceivedness. Thus, it is still important for the government to increase nutrient and supplement intake education, especially in young adults aged below 25 years old.

Una aproximación isotópica a la reconstrucción de historias de vida en sitios arqueológicos de la Quebrada de Amaicha del Valle (Tucumán, Argentina)

In this paper, we analyze the changes in food consumption patterns throughout the lives of five individuals (n=5), one subadult and four adults, found in archaeological sites of El Remate, Bajo los Cardones and Finca Cruz. All of them are associated with the Formative period (ca. 2500 - 1000 years B. P.) and are located in the Quebrada de Amaicha (Tucumán, Argentina). We propose an analysis of the carbon and nitrogen isotopic composition in the dentin of different sections of the same tooth and in different teeth of the five individuals. This approach sheds light on the way in which the characteristics of children’s diets affect their adulthood, as well as providing a more inclusive perspective on consumption patterns in the agropastoralist societies of the study area by integrating young individuals into the analysis. Little intravariation and intervariation was found, with a predominance of food resources framed in the C4 photosynthetic pattern. The exception is an individual, probably female, whose diet was based on C3 resources during the first period of life. This could be the result of the existence of a “childhood diet” or of a change in geographic residence, with both areas being isotopically distinguishable. Finally, we illustrate the methodological steps required to reconstruct life histories through the serial study of human dental pieces. This is a novel approach, which has been applied to human remains from the Argentine Northwest for the first time.

Karakteristik Kabupaten dan Kota di Indonesia dengan Masalah Gizi Ganda pada Penduduk Dewasa Tahun 2018

Economic transitions, industrialization, urbanization, and technological shifts in developing countries have led to nutrition transitions, which has impact on the incidence of double burden malnutrition. This study aims to identify districts/cities with adult double burden malnutrition (DBM) as well as to analyze the characteristics of the region. The design of this research is an ecological study. Samples are 371 districts/cities with adult nutritional problems based on Riskesdas 2018, which categorized into undernutrition, overnutrition, and DBM region. Regional characteristics are classified based on the national figures. Samples were analyzed by spatial and bivariate analysis. There were 38 districts/cities (10.2%) in Indonesia that experienced adult DBM, with the highest number on Java island. The PPH score (87.01), protein intake (63.92 grams/cap/day), proportion of population with sufficient physical activity (62.93%), percentage of poor population (7.95 %), population density (2968 people/km2) and average length of schooling (9.35%) were not significantly different between DBM and overnutrition region (p&gt;0.05). Harvested area (26 890.58 Ha), rice production (152.899.76 Tons/GKG), and rice productivity (152.899.76 Ku/Ha) were not significantly different between DBM and undernutrition region (p&gt;0.05). The DBM region is a districts/cities that has undergone agricultural and economic transformation, resulting in changes in food consumption patterns and physical activity of the population. The incidence of adult DBM in districts/cities is more related to regional characteristics that increase the prevalence of overnutrition.&#x0D; Keywords: adult double burden malnutrition, nutrition transition, ecological study

DAMPAK MENGKONSUMSI MONOSODIUM GLUTAMAT (MSG) DALAM PERKEMBANGAN OTAK ANAK

Advances in information technology have an impact on changes in people's lifestyles, including changes in food consumption patterns that consume more types of fast food. Monosodium glutamate (MSG) is a flavor enhancer that is often used in cooking to enhance dishes. After being given a little vetsin, the food can be delicious because in the vetsin it contains sodium glutanic acid (glutanic acid sodium). Children's age or growth period is more sensitive to the effects of MSG than the adult group. Many people know about the dangers of monosodium glutamate and if they know the side effects of MSG, people should start reducing the use of MSG, but what happens is not as expected, many people still consume MSG in excess. The purpose of this study was to determine the dangers of Monosodium Glutamate (MSG) for body health and to determine the impact of consuming Monosodium Glutamate (MSG) on children's brain development. We used a research method in the form of secondary data. The results showed that the side effects of consuming foods containing MSG could indirectly make a person experience a decline in brain cognitive function.

Structural changes in meat consumption in Vietnam: evidence from household survey data

Purpose This paper aims to provide empirical insight into the trends and structural changes in meat consumption in Vietnam.Design/methodology/approach This study applies the Quadratic Almost Ideal Demand System model on multiple cross-sectional data sets derived from the Vietnam Household Living Standards Survey (VHLSS) of 2004–2016 and follows a consistent two-step procedure to deal with the zero consumption issue. The estimated demand elasticities are then compared and analyzed over time.Findings The empirical results show that in the last decade, meat consumption patterns in Vietnam have undergone a remarkable structural change, with poultry and beef increasingly taking important roles in the meat consumption structure of households. In addition, demographic characteristics, including settlement type, household size and the age of the household head, have significantly influenced meat expenditure patterns in Vietnam.Research limitations/implications The paper considers the demand for meat consumed at home but not meat consumed away from home.Originality/value In many developing countries, increased disposable income, together with rapid urbanization and international integration, has significantly changed consumers' food consumption behaviors. This is one of the first studies using household survey data, which permits the exploration of heterogeneous preferences between consumers, to explore structural changes in food consumption patterns in Vietnam.
