Biofortification: Future Challenges for a Newly Emerging Technology to Improve Nutrition Security Sustainably

Biofortification was coined as a term to define a plant breeding strategy to increase the micronutrient content of staple food crops to reduce the burden of micronutrient deficiencies in low- and middle-income countries. In 2003, the HarvestPlus program, based in the centers comprising the Consultative Group on International Agricultural Research, was initiated to implement the biofortification strategy. This article discusses what has been achieved, what has been learned, and the key challenges to embed biofortification in food systems and to expand its impact. Cost-effectiveness is key to the biofortification strategy. Biofortification piggybacks on the agronomically superior varieties being developed at agricultural research centers. Central plant breeding research discoveries can be spread globally. Farmers have every motivation to adopt the latest high-yielding, high profit crops. High productivity leads to lower food prices. As a consequence, consumers can increase their mineral and vitamin intakes at no additional cost by substituting biofortified staple foods 1-for-1 for nonbiofortified staple foods. After 20 y of investment, biofortified staple food crops are being produced by farmers in over 40 countries and are eaten by hundreds of millions of people. Published nutrition trials have shown nutrient-rich crops to be efficacious. The biofortification strategy is now recognized by the international nutrition community as one effective approach among several interventions needed to reduce micronutrient deficiencies. This is a promising beginning. However, biofortification is still a newly emerging technology. A limitation of biofortification as implemented to date is that densities of single nutrients have been increased in given staple food crops. To reach a higher trajectory, the impacts of biofortification can be multiplied several-fold using genetic engineering and other advanced crop development techniques to combine multiple-nutrient densities with climate-smart traits.

Improving Nutrition Security in Low- and Middle-Income Countries and the Role of Animal-Source Foods.

Nutrition security is challenging in regions where resources are limited and food production is naturally constrained. In low- and middle-income countries (LMICs), undernutrition is high for many reasons, including lack of nutritional diversity and low high-quality protein content. Interest in the role of animal-source food (ASF) in reducing nutrition insecurity is increasing, as evidence from LMICs suggests that consumption of ASF is strongly associated with reduction in stunting, improved diet quality, and overall nutrition, particularly in early stages of life. We review the strengths and limitations of ASF consumption in terms of accessibility, safety, and nutritional benefits compared to non-ASF sources. We present a critical discussion on existing barriers to ASF consumption and its future directions in LMICs. Understanding the role of ASF in improving nutrition security in LMICs is crucial to optimizing public health, designing appropriate interventions, and implementing effective policy in resource-poor settings.

Political Economy of Maternal Child Malnutrition: Experiences about Water, Food, and Nutrition Policies in Pakistan.

This study examined access to water, food, and nutrition programs among marginalized communities in Southern Punjab, Pakistan, and their effects on nutrition. Both qualitative and quantitative data were used in this study. We held two focus group discussions (one with 10 males and one with 10 females) and conducted in-depth interviews with 15 key stakeholders, including 20 mothers and 10 healthcare providers. A survey of 235 households was carried out to evaluate water and food insecurity, with the data analyzed using Wilcoxon's rank-sum test, t-test, and Pearson's chi-square test. The results revealed that 90% of households experienced moderate-to-severe water insecurity, and 73% faced moderate-to-severe food insecurity. Household water and food insecurity were positively correlated with each other (correlation coefficient = 0.205; p = 0.004). Greater household water (p = 0.028) and food insecurity (p < 0.001) were both associated with higher perceived stress. Furthermore, lower socioeconomic status was strongly related to higher levels of water (p < 0.001) and food insecurity (p < 0.001). Qualitative findings highlight the impact of colonial and post-colonial policies, which have resulted in water injustice, supply issues, and corruption in water administration. Women face significant challenges in fetching water, including stigma, harassment, and gender vulnerabilities, leading to conflicts and injuries. Water scarcity and poor quality adversely affect sanitation, hygiene, and breastfeeding practices among lactating mothers. Structural adjustment policies have exacerbated inflation and reduced purchasing power. Respondents reported a widespread lack of dietary diversity and food quality. Nutrition programs face obstacles such as the exclusion of people with low social and cultural capital, underfunding, weak monitoring, health sector corruption, and the influence of formula milk companies allied with the medical community and bureaucracy. This study concludes that addressing the macro-political and economic causes of undernutrition should be prioritized to improve nutrition security in Pakistan.

Coordinates of Food and Nutrition Security in States with Limited Agricultural Resources

Abstract Food security is a topic of a large interest, the new approach shifting towards nutrition security, from people access to sufficient towards safe and nutritious food, emphasizing the structure of the diet and the importance of the nutrients in assuring a healthy life. But malnutrition problems affect people worldwide, in different forms, both undernourishment and overweight and obesity, mostly in countries where agricultural resources, as one of the main sources of food, are scarce. Such a country is United Arab Emirate, where people have access to sufficient food, but based on imports, signalizing a low level of food self-sufficiency. Furthermore, the alarming rate of obesity of 30% raises questions about the structure of the diet and nutrition security. The aim of the study is to determine the level of food security in the United Arab Emirates and identify the factors behind it. Statistical data referring to food and nutrition security in United Arab Emirate have been analysed and predictions have been made using machine learning algorithms. The results are relevant for underpinning food policy at macroeconomic level, helping decision makers in finding solutions for improving nutrition security and food self-sufficiency.

Modelling seasonal and geographical n-3 polyunsaturated fatty acid contents in marine fish from the Northeast Atlantic Ocean

Demand for n-3 polyunsaturated fatty acids (n-3 PUFAs) exceeds supply. Large-scale studies on effects of season and geography of n-3 PUFAs in marine fish from the Northeast Atlantic Ocean (NEAO) may be used to optimize utilization and improve nutrition security. Using a sinusoid model, seasonal cycles of n-3 PUFAs were determined and found to be species-specific and clearly pronounced for the pelagic zooplankton feeding species. The Greenland halibut showed very little seasonal variation. The n-3 PUFA content in North Sea autumn-spawning (NSAS) herring peaked in summer, while Norwegian spring-spawning (NSS) herring and mackerel had their peak in autumn. A time shift of peaks in n-3 PUFAs between the two herring stocks was detected, likely due to different spawning strategies in addition to a delay of n-3 PUFAs flux in the northern regions of the NEAO. This study demonstrates that consideration of nutrient contents, such as n-3 PUFAs, when organizing and structuring fishery approaches may improve overall nutritional yield. Based on total annual Norwegian fish landings and seasonal variation in n-3 PUFA contents, n-3 PUFAs yield could theoretically be increased from 13.79 kilo ton per year from the current fishing tactics, to 15.54 if the pelagic species were only caught during the time of their seasonal n-3 PUFA peaks. Pelagic fish is a good source for dietary n-3 PUFAs, but harvest timing will also influence n-3 PUFAs intake by human consumers. One portion of fatty fish harvested during winter/spring may not meet the weekly intake reference nutritional guidelines for n-3 PUFAs. Marine n-3 PUFAs yields also varied geographically and decreased southwards, with the lowest values in Skagerrak. This study can serve as a model to understand patterns of reproductive cycles and geographical distribution of n-3 PUFAs in fatty fish from the NEAO and the novel approach may be useful to support sustainable, seasonal fishing programmes for optimization of n-3 PUFAs yields.

Stakeholder-driven transformative adaptation is needed for climate-smart nutrition security in sub-Saharan Africa

Improving nutrition security in sub-Saharan Africa under increasing climate risks and population growth requires a strong and contextualized evidence base. Yet, to date, few studies have assessed climate-smart agriculture and nutrition security simultaneously. Here we use an integrated assessment framework (iFEED) to explore stakeholder-driven scenarios of food system transformation towards climate-smart nutrition security in Malawi, South Africa, Tanzania and Zambia. iFEED translates climate–food–emissions modelling into policy-relevant information using model output implication statements. Results show that diversifying agricultural production towards more micronutrient-rich foods is necessary to achieve an adequate population-level nutrient supply by mid-century. Agricultural areas must expand unless unprecedented rapid yield improvements are achieved. While these transformations are challenging to accomplish and often associated with increased greenhouse gas emissions, the alternative for a nutrition-secure future is to rely increasingly on imports, which would outsource emissions and be economically and politically challenging given the large import increases required.

Nutrition quality response of orange‐fleshed sweet potato (Ipomoea Batatas L. Lam) varieties to deficit irrigation in Tanzania

AbstractMalnutrition in all its forms is a global problem, with the worst effects felt in developing countries. The importance of producing food to improve nutrition security is self‐evidently a promising approach to combating malnutrition. The present study assessed the nutritional quality response of orange‐fleshed sweet potato (OFSP) varieties to deficit irrigation (DI). The study's specific objectives were to (i) evaluate yield and root quality and (ii) assess the nutritional root yield and nutritional water productivity of selected OFSP varieties under full and DI. Beta‐carotene, iron, and zinc were the root quality parameters studied. A factorial arrangement of treatments was laid out in a randomized complete block design (RCBD). The irrigation rates used for scheduling were 100% (full irrigation), 60% (60 [DI]), and 30% (30 [DI]) of total available water (TAW). The test varieties were Naspot‐13 and Jewel of the OFSP crop. The beta‐carotene content of the Jewel cultivar was 27% higher than that of the Naspot‐13 cultivar. However, neither cultivar's root quality changed under DI. The results show that serving 125 g of boiled OFSP varieties provides more than 100% of vitamin A, sufficient iron, and minimal zinc dietary requirements for 4‐ to 8‐year‐old children and 10‐ to 50‐year‐old pregnant women. In general, the nutritional water productivity of root quality parameters increased with a decrease in water application. In conclusion, a positive water‐food‐nutrition nexus was established under the Naspot‐13 variety, suggesting a capacity for alleviating vitamin A, iron, and zinc deficiency health‐related problems, particularly in children and pregnant women in regions with limited water resources. Therefore, adoption of DI strategies for underutilized crops using smart pressurized irrigation systems could be significant in undertaking water management reforms.

Exploring the potentials of underutilised indigenous legume for nutritional welfare of rural households in the Northern Part of Oyo State Nigeria

This study analyzed the nature of household demand and the factors that determined household demand for pigeon pea in Oyo State, Nigeria. A multistage sampling technique was employed to select 150 households. Primary data were collected using a structured questionnaire and analyzed using descriptive statistics and Almost Ideal Demand System (AIDS) model. The results of the study showed that the majority(87.3 %) of the sample household were male-headed, married (80 %), between the ages of 40 and 60 years, with a mean household size of nine persons, and their primary occupation was farming. On average, households consumed 2.1 kg of pigeon pea per month and the household head earned ₦460,000 ($1150) per annum. The result of the AIDS model showed that pigeon pea was a normal and necessary food, and as well as complementary food for tubers and cereals. Further, household head’s age, formal education and pigeon pea attributes (taste and cooking time), significantly influenced household’s demand for pigeon pea. Research efforts should, therefore, be tailored towards improved varieties with less cooking time, better taste and awareness creation of its nutritional value to increase production, marketing and consumption for improved nutrition security in the study area.

Challenges and Opportunities for Equity in US School Meal Programs: A Scoping Review of Qualitative Literature Regarding the COVID-19 Emergency.

The emergency school meals program provided free meals to children in the United States (US) during COVID-19-related school closures. This scoping review aims to synthesize the existing qualitative empirical evidence published between March 2020 and January 2023 on the operations and utilization of emergency school meal programs during the pandemic. Qualitative, US-based peer-reviewed literature was collected from three sources: (1) parent review of all federal nutrition assistance programs; (2) systematic search of four databases; and (3) manual search of grey literature. Identified scientific articles and grey literature reports (n = 183) were uploaded into Covidence and screened for duplicates and inclusion/exclusion criteria. Our final sample included 21 articles/reports, including 14 mixed methods and seven qualitative-only projects. Articles spanned all U.S. states. Articles had similar research questions to understand school meals and/or general food access during COVID-19, with an emphasis on long-term policy implications. Hybrid deductive/inductive analytic coding was used to analyze data, utilizing domains from the Getting to Equity Framework (GTE). GTE considers multi-level factors that influence nutrition behavior while centering more equitable pathways to improve nutrition security and reduce adverse health. Findings were sorted into two categories: operational challenges during the pandemic and solutions to address inequities in school meal distribution during and after the pandemic, particularly during school closures such as summers or future emergencies. Key challenges related to supply chain issues, safety, and balancing families' needs with limited staff capacity. Programs addressed equity by (a) reducing deterrents through federally issued waivers and increased communications which allowed the serving of meals by programs to families who previously did not have access, (b) building community capacity through collaborations and partnerships which allowed for increased distribution, and (c) preparing and distributing healthy options unless barriers in supply chain superseded the effort. This review highlights the importance of emergency school meal programs and provides insights into addressing challenges and promoting equity in future out-of-school times. These insights could be applied to policy and practice change to optimize program budgets, increase reach equitably, and improve access to nutritious meals among populations at highest risk for nutrition insecurity.

Dual‐purpose crops for grain and fodder to improve nutrition security in semi‐arid sub‐Saharan Africa: A review

AbstractAddressing the challenge of food and nutrition insecurity in Sub‐Saharan Africa (SSA) will require innovative agriculture production systems that support multiple objectives. In recent years, several high‐yielding, and nutrient‐dense varieties of cowpea (Vigna unguiculata (L.) Walp), pearl millet (Pennisetum glaucum (L.) R. Br.), and sorghum (Sorghum bicolor (L.) Moench) have been developed purposely as dual‐purpose (DP) varieties in SSA to meet human nutrition and livestock feed needs. This review synthesized published data on DP varieties from cowpea, pearl millet, and sorghum. Findings showed that DP crops and varieties were largely grown by smallholder farmers in a variety of soil and climatic conditions with production systems characterized by large gaps between attainable and actual crop yields which varied significantly among regions. While the grain and fodder yield of traditional varieties (TV) of cowpea averaged 700 kg ha−1 and 860 kg ha−1, respectively, the reported grain yield of DP varieties was 1100 kg ha−1 and 2150 kg ha−1 for fodder. The average grain yield of TV millet varieties was 750 kg ha−1 and 2500 kg ha−1 for fodder. Similarly, average grain yield for DP millet varieties was 2000 kg ha−1 and 4200 kg ha−1 fodder. Dual‐purpose sorghum varieties yielded greater grain (&gt;3000 kg ha−1) and fodder (3500 kg ha−1) compared to TV. Little data were obtained on the nutritive qualities of cowpea, millet, and sorghum DP varieties. However, DP millet varieties were reported to be more digestible than TV varieties. Furthermore, adoption of DP varieties improves fertilizer use efficiency, profitability, environmental sustainability, and resilience of the whole farm system compared to TV. Considering fertilizer's high prices, availability, and quality in semi‐arid countries in addition to farmer poverty level, economic evaluation and environmental impact assessment are critical before wide dissemination.

Mineral Composition and Consumer Acceptability of Amaranthus Leaf Powder Supplemented Ujeqe for Improved Nutrition Security.

Malnutrition, especially micronutrient deficiency, is a widespread health challenge that predominantly affects young children, young ladies who are within the productive age, refugees, and older adults who reside in rural communities and informal settlements in underdeveloped and developing countries. Malnutrition is caused by consuming either too little or too much of one or more food nutrients. Additionally, monotonous dietary lifestyle, especially the over-reliance on staple foods, is identified among the top factors limiting many individuals' intake of essential nutrients. Thus, enriching starchy and cereal-based staple foods including Ujeqe (steamed bread) with fruits and especially leafy vegetables is being suggested as a strategic medium for essential nutrient delivery to malnourished populations and especially the Ujeqe regular consumers. Amaranthus, called pigweed, has been rediscovered as a nutrient-dense multipurpose plant. The seed has been explored as a nutrient-enhancer in staple foods; however, the leaves are underutilized, especially in Ujeqe. This study aims to enhance the mineral content of Ujeqe. An integrated research approach was used where Amaranthus dubius was self-processed into leaf powder. Amaranthus leaf powder (ALP), and the ALP-supplemented wheat flour Ujeqe prototypes 0%, 2%, 4%, and 6% were investigated for their mineral composition. Sensory evaluations of enriched Ujeqe were conducted using 60 panelists on a five-point hedonic scale. Findings show that the moisture contents of the raw materials and the supplemented prototypes were low, indicating a good shelf life of the food ingredient before being used for Ujeqe development. Carbohydrates of raw materials ranged from 41.6-74.3%, fat ranged from 1.58-4.47%, ash ranged from 2.37-17.97%, and protein ranged from 11.96-31.56%. Additionally, fat, protein, and ash content had significant differences at (p < 0.05). The moisture content of enhanced Ujeqe was equally low, connoting keeping quality of the sample. The increase concentration of ALP led to an enriched Ujeqe especially in the ash and protein content. Similarly, calcium, copper, potassium, phosphorus, manganese, and iron content were significantly influenced at (p < 0.05); 2% ALP-supplemented Ujeqe was the most acceptable prototype as the control sample, 6% was the least preferred prototype. Although ALP dubius can enrich staple foods including (Ujeqe), this study declared that higher addition of ALP dubius leads to low consumer acceptability rate of the Ujeqe, which is not statistically significant. Amaranthus is an economical source of fiber, which was not investigated in the study. Therefore, further studies can explore the fiber content of the ALP-supplemented Ujeqe.

Applying a nutrition security lens to the Dietary Guidelines for Americans to address metabolic health.

Nutrition security - access to food that promotes well-being and prevents or treats disease, particularly among racial and ethnic minority populations, lower income populations, and rural and remote populations - is a national priority. Leading causes of death and disability in America, such as heart disease, stroke, cancer, and diabetes that disproportionately affect minorities are linked to preventable diet-related risk factors. Mounting evidence indicates that adherence to a lower-carbohydrate dietary pattern is associated with weight maintenance, improved blood glucose and insulin control, lower blood pressure, reduced markers of inflammation, and a more favorable lipid profile. Additionally, prior concerns regarding the higher fat and cholesterol content of this dietary pattern are less founded in modern research. The inclusion of a lower-carbohydrate option that meets all essential nutrient requirements aligns with the contemporary movement toward more flexibility and precision nutrition. Most important, a lower-carbohydrate option positions the Dietary Guidelines for Americans to more accurately reflect the current scientific evidence and more effectively address the metabolic health of the nation. Further, it has the potential to improve nutrition security by addressing metabolic diseases that disproportionately affect people from historically marginalized racial, ethnic, socioeconomic, and cultural backgrounds. Given that most American adults are living with at least one diet-related chronic metabolic disease, updating the Dietary Guidelines for Americans to recognize and reflect the poor health status of the general population is prudent and urgent.

Improving Nutrition Security for Individuals With Serious Mental Illnesses: A Partnership of Public and Nonprofit Agencies.

In conjunction with multiple partners (state agencies, nonprofits, a university, and key stakeholders and content experts), the authors are implementing and evaluating an intervention intended to enable individuals with serious mental illnesses living in community residences (i.e., group homes) and supportive housing apartments to-with support from residential staff-access, purchase, prepare, and enjoy healthy, local produce. The three-component intervention makes fresh produce more accessible; improves its affordability; and conveys knowledge and skills related to purchasing, preparing, and eating healthy foods, especially vegetables. The intervention is being evaluated in preparation for possible larger-scale implementation and potential dissemination to other populations experiencing nutrition insecurity.

Contribution of natural food environments to nutritional intake and biomarker status: insights from the women of indigenous santhal communities of Jharkhand, India

BackgroundMany indigenous communities reside in biodiverse environments replete with natural food sources but show ​poor access and utilization.MethodsTo understand the links between indigenous food access, dietary intakes, and biomarkers, we conducted a cross-sectional study among women of the Santhal Community (n = 211) from 17 villages in the Godda district of Jharkhand, India. Survey methods included household surveys, dietary intake assessment (24 HDR) and micronutrient and inflammatory biomarkers' estimation.ResultsThe diversity in access to foods from different natural sources expressed as Food access diversity index was low. This led to poor consumption and thus a low Minimum Dietary Diversity. The mean nutrient intake was less than the estimated average requirement for all nutrients. Women with higher dietary diversity scores had higher nutrient intakes. Thiamine and calcium intakes were significantly higher in women consuming indigenous foods than non-consumers. One-fourth of the women had elevated levels of inflammatory biomarkers. The prevalence of iron deficiency was approximately 70%. Vitamin A insufficiency (measured as retinol-binding protein) was observed in around 33.6% women, while 28.4% were deficient. Household access to natural food sources was associated with specific biomarkers. The access to kitchen garden (baari) was positively associated with retinol-binding protein levels and negatively with inflammatory biomarkers, while access to ponds was positively associated with ferritin levels.ConclusionThe findings highlight the role of access to diverse natural foods resources, including indigenous foods, for improving nutrition security in indigenous communities. Nutrition and health programs promoting indigenous food sources should include the assessment of biomarkers for effective monitoring and surveillance.

Food insecurity and the role of food assistance programs in supporting diet quality during the COVID-19 pandemic in Massachusetts.

Economic and supply chain shocks resulting from the COVID-19 pandemic in 2020 led to substantial increases in the numbers of individuals experiencing food-related hardship in the US, with programs aimed at addressing food insecurity like the Supplemental Nutrition Assistance Program (SNAP) and food pantries seeing significant upticks in utilization. While these programs have improved food access overall, the extent to which diet quality changed, and whether they helped mitigate diet quality disruptions, is not well understood. To evaluate food insecurity, food pantry and/or SNAP participation associations with both diet quality as well as perceived disruptions in diet during the COVID-19 pandemic among Massachusetts adults with lower incomes. We analyzed complete-case data from 1,256 individuals with complete data from a cross-sectional online survey of adults (ages 18 years and above) living in Massachusetts who responded to "The MA Statewide Food Access Survey" between October 2020 through January 2021. Study recruitment and survey administration were performed by The Greater Boston Food Bank. We excluded respondents who reported participation in assistance programs but were ineligible (n = 168), those who provided straightlined responses to the food frequency questionnaire component of the survey (n = 34), those with incomes above 300% of the federal poverty level (n = 1,427), those who completed the survey in 2021 (n = 8), and those who reported improved food insecurity (n = 55). Current dietary intake was assessed via food frequency questionnaire. Using Bayesian regression models, we examined associations between pandemic food insecurity, perceived disruption in diet, diet quality, and intakes of individual foods among those who completed a survey in 2020. We assessed interactions by pantry and SNAP participation to determine whether participation moderated these relationships. Individuals experiencing food insecurity reported greater disruption in diet during the pandemic and reduced consumption of healthy/unhealthy foods. Pantry participation attenuated significant associations between food insecurity and lower consumption of unhealthy (b = -1.13 [95% CI -1.97 to -0.31]) and healthy foods (b = -1.07 [-1.82 to -0.34]) to null (unhealthy foods: -0.70 [-2.24 to 0.84]; healthy foods: 0.30 [-1.17 to 1.74]), whereas SNAP participation attenuated associations for healthy foods alone (from -1.07 [-1.82 to -0.34] to -0.75 [-1.83 to 0.32]). Results were robust to choice of prior as well as to alternative modeling specifications. Among adults with lower incomes, those experiencing food insecurity consumed less food, regardless of healthfulness, compared to individuals not experiencing food insecurity. Participation in safety-net programs, including SNAP and pantry participation, buffered this phenomenon. Continued support of SNAP and the food bank network and a focus on access to affordable healthy foods may simultaneously alleviate hunger while improving nutrition security.

Collaborative Strategies to Improve Nutrition Security and Education: Lessons Learned During a Pandemic.

The COVID-19 pandemic intensified disparities for underserved populations as accessing resources became more difficult. Dairy Council of California launched the Let's Eat Healthy initiative to address nutrition security through collaborative solutions in the school environment. To ensure nutrition security for children and families, nutritious food and nutrition education must go hand-in-hand. Improving access to high quality food can help address the health disparities that exist for people who are at increased risk for food insecurity. Nutrition education supports students' holistic learning and social and emotional learning skills. Nutrition education models must be increasingly flexible in the face of ongoing challenges. Collaborative efforts to connect food access hubs, such as schools, with support and resources to provide evidence-based nutrition education and agricultural literacy can equip individuals and communities with the knowledge, skills, and ability to make nutrient-rich food choices. Investments and strategies in nutrition security that utilize the Individual plus Policy, System, and Environmental (I + PSE) model, such as the Let's Eat Healthy initiative, will effectively influence positive behavior change and improve community health. Navigating challenges in a rapidly changing environment requires people and organizations to work together, across disciplines, to leverage knowledge, experience, resources, expertise, and creative thinking. Improving access to healthy food and nutrition education will be most effective when done through collaboration.

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

ABSTRACTThere 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.

Impacts of agricultural taxation in Sub‐Saharan Africa: Insights from agricultural produce cess in Tanzania

AbstractThis article analyses the economic impacts of agricultural produce cess in Tanzania and compares its effectiveness with alternative reform options relying on its removal or reduction. Produce cess is one of the common forms of agricultural taxation in Sub‐Saharan Africa. This analysis is performed using the farm‐household model FSSIM‐Dev, which is applied to a country representative sample of 3134 individual farm households taken from the 2012/2013 Tanzania National Panel Survey. Simulations show that the current produce cess is rather high and its removal or reduction would increase production intensity and boost farm income, ranging between +2% and +21% depending on options and regions. These positive impacts are driven by land productivity improvement rather than area reallocation. The largest impacts are experienced in northern and western highlands. Large farms and farms specialized in cash crops tend to gain more from the abolishment or reduction of produce cess. The increase in both production and income is, however, not sufficient to significantly reduce rural poverty and improve nutrition security. Finally, results show that a uniform cess rate of 1% for all crops seems to be the most appropriate policy option. It gives the best trade‐off between government revenue loss and farmers’ economic gain.
