This review elucidates the role of dietary factors in influencing myokine secretion, complementing the recognized benefits of physical activity on metabolic health. While exercise is known to positively modulate myokines, contributing to their health-promoting effects, an exploration into how diet affects these critical cytokines remains sparse. Through analysis of the literature, this work identifies dietary patterns that markedly affect myokine levels, underscoring the complex relationship between nutrition and myokine activity. The investigation reveals that specific dietary approaches can profoundly alter myokine secretion, suggesting an essential avenue for combined dietary and exercise interventions to optimize health outcomes. These insights highlight the need for further detailed study into diet-induced myokine modulation. [ABSTRACT FROM AUTHOR]

Achieving a balanced and diverse diet remains a challenge for many people, contributing to an ongoing burden of micronutrient deficiencies, particularly in low-income settings. Fortification or dietary diversification are common food-based approaches. We conducted a scoping review to: 1) find evidence on whether combined food--based strategies are more effective than single strategies, and 2) understand how strategies implemented together could complement each other to achieve optimal nutritional impact on populations. Peer-reviewed articles selected (n = 21) included interventions or observational studies (n = 13) and reviews (n = 8). We found little evidence of an added nutritional impact. On the other hand, it is apparent that fortification and dietary diversification target different types of settings (urban compared with rural) and foods (that is, low priced compared with highly priced). Further research is needed to understand the complementarity of these approaches and establish evidence of the effectiveness of combined strategies to foster policy adoption. [ABSTRACT FROM AUTHOR]

Abstract Mycotoxins are toxic secondary metabolites produced by filamentous fungi that are commonly detected as natural contaminants in agricultural commodities worldwide. Mycotoxin exposure can lead to mycotoxicosis in both animals and humans when found in animal feeds and food products, and at lower concentrations can affect animal performance by disrupting nutrient digestion, absorption, metabolism, and animal physiology. Thus, mycotoxin contamination of animal feeds represents a significant issue to the livestock industry and is a health threat to food animals. Since prevention of mycotoxin formation is difficult to undertake to avoid contamination, mitigation strategies are needed. This review explores how the mycotoxins aflatoxins, deoxynivalenol, zearalenone, fumonisins and ochratoxin A impose nutritional and metabolic effects on food animals and summarizes mitigation strategies to reduce the risk of mycotoxicity.

Food environments exert a significant effect on population dietary choices and health outcomes. Policies that influence the food environment, can have a significant impact on individual and population dietary choices. This rapid review assessed the nature and interaction within the Ghanaian food environment, and the impact that existing school, workplace, and national food policies have on dietary intake and nutritional outcomes. Online databases and university repositories were searched for relevant articles and documents. A total of forty articles and documents were included in the review. Majority of the reviewed papers (85%) used a cross-sectional design. The findings show that traditional outlets (open markets) constitute the main food source among the Ghanaian populace, while convenience stores serve as an important source of processed foods. Prepared local foods are often consumed outside the home and are mainly sourced from street food vendors. Street foods are perceived as less expensive, convenient, and delicious. The food environment was found to influence dietary acquisition, intake, and nutritional outcomes. Although most nutrients provided by the School Feeding Programme (SFP) are below recommended intake standards, the SFP contributes positively to improved diets and nutrition status of school-age children. Children attending SFP-implementing schools experience higher intakes of protein, iron, zinc, calcium, vitamin A, folate, and have higher haemoglobin, and lower prevalence of stunting, underweight, and thinness than children in non-SFP implementing schools. Availability of a private room for breastfeeding mothers improved breastfeeding frequency. Ghana's fatty meat restriction policy has reduced the availability and sale of fatty meat on the Ghanaian market. Reported drivers and barriers to healthy foods consumption include socio-economic factors, media information, food storage facilities, cultural perception, fruit seasonality, knowledge on the nutrient value of fruits and vegetables, safety profile of fruits and vegetables, and contribution of household production to dietary intake. In conclusion, the food environment review reveals the drivers of availability, barriers to healthy food access, and impact of interventions and policies on the Ghanaian food environment.

The current food system is directly influenced by the increase in environmental problems and nutritional inequality globally. Financial and political collapses, health crises, excessive urbanization, and rapid industrialization are some of the principal factors threatening the food supply's security. The food system needs a profound transformation to avoid ecosystem destabilization and a global food crisis. Concerning this transformation, we are certain that the first step for a successful food system change is global resilience thinking. To reach an integrated food system, we proposed introducing the resilient concept linked with other known concepts, such as circular economy and sustainability. A resilient food system can recover over time, ensuring the supply of sustainable and quality food and access to all. This would mean redesigning the value chains in the food system, re‐educating consumers to implement a healthier diet, and introducing technology such as digital innovation. Re‐evaluating these relevant points, redesigning the focus of the food system, not only for economic efficiency but also including significant trade‐offs, or valuing other services in the food system, are essential to reaching the desired resilience. © 2021 Society of Chemical Industry.

The present paper aims to review and assess the impact of the COVID-19 lockdown on food loss and waste (FLW), evaluating the environmental, social, nutritional, and economic repercussions, as well as the challenges addressed by the food sector and the recovery strategies. The main outcomes reveal that the major challenges reside in mobility restrictions, labor and products shortage along the supply chain, and the management of an important amount of household FLW. Measures such as secondary feeding strategies, alternative distribution channels, and e-commerce stand out in achieving a more sustainable and resilient food system.

Biofortified orange maize open-pollinated varieties and hybrids with higher provitamin A carotenoids (pVACs) have been released in sub-Saharan Africa and will be introduced throughout the local food systems. This study assessed the impact of steeping, a traditional processing method, on retention of carotenoids and starch pasting properties of porridges made from select biofortified maize genotypes. Steeping had a modest effect (

The carotenoid composition of gari made from biofortified cassava (BG) was compared to that of existing gari of similar appearance but made from white cassava with added red palm oil (RPG). Storage of both yellow gari products was modelled at ambient temperatures typical of tropical areas (19–40 °C) over a 3-month-period at constant relative humidity. Carotenoid content and hence vitamin A activity of the gari products decreased markedly with time and temperature. Trans-β-carotene degradation fitted well the kinetics predicted by the Arrhenius model, in particular for BG. Activation energies for trans-β-carotene were 60.4 and 81.0 kJ mol −1 for BG and RPG respectively ( R 2 = 0.998 and 0.997, respectively); hence the minimum energy to cause degradation of trans-β-carotene in gari was lower with BG. Rates of degradation of 9-cis-β-carotene in gari were of the same order as with trans-β-carotene. Although the initial content of trans-β-carotene was twice as high in the BG compared to RPG, trans-β-carotene in BG degraded much faster. Results showed that the average shelf life at ambient temperature for BG was significantly shorter than for RPG and therefore carotenoids in BG were less stable than in RPG. [ABSTRACT FROM AUTHOR]

Increasingly, policymakers are setting ambitious goals for sustainability in public procurement, integrated across different pillars. Such ambitions are apparent in public catering services, where procurement models have been shifting towards greater localisation of supply chains and purchasing of more organically grown food. To date however, few studies have examined empirically what the impacts of different procurement models are across these multiple pillars of sustainability. This research aimed to fill the gap, by measuring and comparing the environmental, economic and nutritional outcomes of different models of school meals procurement. Case studies were undertaken of ten primary school meals services in five European countries, capturing different procurement model types. Results showed carbon emissions ranged from 0.95 kgs CO 2 e per meal in the lowest case to 2.41 kgs CO 2 e in the highest case, with adoption of low carbon food waste disposal methods and reduction of the amount of ruminant meat in the menus being the most important actions for lowering emissions. In terms of economic impact, local economic multiplier ratios ranged from 1.59 to 2.46, and although the level of local food sourcing contributed to these ratios, the effect was eclipsed, in some cases, by investment in local catering staff. Meanwhile, implementation of a robust standards regime and improving canteen environment and supervision were the most important actions for nutritional quality and intake. The paper discusses the implications of the findings for integrated, sustainable models of food procurement. [ABSTRACT FROM AUTHOR]

Improving the food supply chain efficiency has been identified as an essential means to enhance food security, while reducing pressure on natural resources. Adequate food loss and waste (FLW) management has been proposed as an approach to meet these objectives. The main hypothesis of this study is to consider that the "strong fluctuations and short-term changes" on eating habits may have major consequences on potential FLW generation and management, as well as on GHG emissions, all taking into account the nutritional and the economic cost. Due to the exceptional lockdown measures imposed by the Spanish government, as a consequence of the emerging coronavirus disease, COVID-19, food production and consumption systems have undergone significant changes, which must be properly studied in order to propose strategies from the lessons learned. Taking Spain as a case study, the methodological approach included a deep analysis of the inputs and outputs of the Spanish food basket, the supply chain by means of a Material Flow Analysis, as well as an economic and comprehensive nutritional assessment, all under a life cycle thinking approach. The results reveal that during the first weeks of the COVID-19 lockdown, there was no significant adjustment in overall FLW generation, but a partial reallocation from extra-domestic consumption to households occurred (12% increase in household FLW). Moreover, the economic impact (+11%), GHG emissions (+10%), and the nutritional content (−8%) complete the multivariable impact profile that the COVID-19 outbreak had on FLW generation and management. Accordingly, this study once again highlights that measures aimed at reducing FLW, particularly in the household sector, are critical to make better use of food surpluses and FLW prevention and control, allowing us to confront future unforeseen scenarios. Unlabelled Image • A multivariable analysis on FLW behavior for the COVID-19 outbreak in Spain was done. • Short-term disruptions on eating habits influence food loss and waste (FLW) patterns. • Higher FLW generation rates (+12%) during early stages of the outbreak were observed. • Economic and environmental impacts rose notably, while nutritional quality decreased. • FLW reduction policies must consider future unexpected food disruption scenarios.

Biofortified orange maize open-pollinated varieties and hybrids with higher provitamin A carotenoids (pVACs) have been released in sub-Saharan Africa and will be introduced throughout the local food systems. This study assessed the impact of steeping, a traditional processing method, on retention of carotenoids and starch pasting properties of porridges made from select biofortified maize genotypes. Steeping had a modest effect (<9% loss) on total carotenoid stability during relatively shorter steeping periods (<72 h). However, more extended steeping periods (up to 120 h) had a detrimental effect on total carotenoid recovery (61% loss). Xanthophylls showed greater stability (82% retention) compared to carotenes (30% retention) during subsequent wet cooking of fermented flours. Interestingly, steeping of maize did modify pasting properties, with peak viscosities increasing from 24–72 h of steeping potentially impacting cooking stability. These results suggest that steeping can impact carotenoid retention and potentially optimal steeping times would be 24–72 h for acceptable carotenoid retention. [ABSTRACT FROM AUTHOR]

Maize is a staple crop that has been the subject of biofortification efforts to increase the natural content of provitamin A carotenoids. Although significant progress toward increasing provitamin A carotenoid content in maize varieties has been made, postharvest handling factors that influence carotenoid stability during storage have not been fully established. The objectives of this study were to determine carotenoid profiles of six selected provitamin A biofortified maize genotypes at various developmental stages and assess the stability of carotenoids in maize kernels during controlled storage conditions (12 month period), including elevated temperature and relative humidity. There were no significant changes in the content of individual carotenoids within genotypes during kernel development from 45 days after pollination through the time of harvest. Carotenoid losses through traditional grain drying were also minimal (<9%). However, the stability of carotenoids in maize kernels over storage time after harvest was found to be dependent on both temperature and humidity, with variation observed among genotypes. Different forms of provitamin A carotenoids follow similar degradation rates. The genotype C17xDE3 had a degradation rate 2 times faster than those of the other genotypes evaluated (P < 0.001). These differences in carotenoid stability under controlled storage were attributed, in part, to observed differences in the physical properties of the kernels (surface area and porosity). These results support the notion that effective control of moisture content and temperature of the kernels during storage conditions is essential to reduce the speed of degradative reactions.

The amounts of earthworm surface casts were monitored for 200 days after commencement of casting in three alley cropping experiments of different ages and hedgerow species. Casts were collected twice per week in transects from under the hedgerow to the middle of the interrowspace. Average annual cumulative amounts of casts were higher in alley cropping systems with one to five years of cropping than in the no-tree control. After five years of cropping, amounts of casts were similar in all treatments. Within the alley cropping systems, casting activity was highest immediately under the hedgerows and decreased towards the middle of the interrow space. In systems using Leucaena leucocephala as hedgerow species, the hedgerow to interrow space gradientof casting activity became more pronounced with increasing length ofcropping. Casting activity in the interrow space was reduced by 12%,55%, 80% and 86% in the first, fourth, sixth and seventh year of cropping, respectively, compared to the casting activity under the hedgerows. Senna siamea, which produced a more recalcitrant mulch, did notshow such a strong decline in casting in the interrow space. In a Dactyladenia barteri system, the difference in casting between interrowspace and hedgerows was insignificant. With perpendicular distance from the hedge, largest gradients in casting activity occurred close to the hedgerows with up to ?4.00 Mg ha^-1 cm^-1 in L. leucocephala but only ?1.23 and ?0.76 Mg ha^-1 cm^-1 in S. siamea and D. barteri, respectively. The shading effect of trees and a relatively low level ofsoil disturbance is apparently more beneficial for earthworms in a cropped system than a high supply of readily available food from fast decomposing L. leucocephala prunings.
