Food security and nutrition and sustainable agriculture

Future sustainable food systems should more efficiently use natural resources and reduce food waste. Upcycled food – foods elevated in value through ingredients otherwise wasted or previously thought inedible – constitutes a new approach contributing to this much needed transition. Successful market launches of such foods requires favourable consumer perception of these products, knowing the factors determining acceptance, and an adequate communicational framing of the new concept.
Edible macroalgae (i.e., ‘seaweeds’) are a nutritious and sustainable alternative to animal-based proteins. However, consumption of seaweeds in Western countries remains low, and little is known about individual drivers of acceptance. The aim of this study was to further explore the consumer acceptability of seaweed-based food products in the UK. In an online study (N = 476), participants were presented with a general description of edible seaweeds, and descriptions of seaweed-based food products (e.g., ‘seaweed burger’).
Concerns over the impact of global meat production and consumption patterns are leading to increasing interest in alternative sources of protein. This study provides new insight into consumers’ attitudes towards different protein products and factors associated with the acceptance of lab-grown chicken and lab-grown beef.
Meat induces large environmental impact while supplying important nutrients, and meat substitutes are increasingly adopted as direct replacers of meat products. This study assessed the environmental impact of a pork schnitzel and two soy-based schnitzels in terms of three different functional units to reflect the products’ functions as meal components and suppliers of high quality proteins. For a functional unit of 1 kg of product, the pork schnitzel induces the largest environmental impact for most environmental impact indicators.
Cow's milk is considered a staple in many diets due to its high nutritional value. It contains almost every nutrient that the human body needs. Milk is consumed as a beverage, poured on several foods, and added to coffee, tea, and smoothies. Furthermore, many food products are produced from cow's milk, such as ice cream, yogurt, cheese, butter, cake, desserts, and others. However, it is not a suitable option for everyone for reasons, including lactose intolerance, milk allergy, dietary restrictions, and potential health risks.
The availability of food is the basic entity for the survival of human. The resources that make a nation food secured is guided by multiple factors and can be evaluated using a set of indicators. We present an assessment for ranking food security of the South Asian Association for Regional Cooperation (SAARC) nations represented by Afghanistan, Bangladesh, Bhutan, India, Nepal, the Maldives, Pakistan and Sri Lanka using a set of indicators under the prevailing scenarios of climate change.
Several studies have indicated that a global reduction in meat consumption is inevitable for sustainability and public health, despite the challenges inherent to changing eating habits. The purpose of this article is to pursue a stock-take of consumer behavior with regard to reducing meat consumption through a literature review using bibliometric analysis. The findings show the multidisciplinary nature of the field, which is in full development and with many knowledge gaps. Publications are concentrated in a few dominant journals and originated exclusively in developed countries.
Food security and sustainability are the most urgent problems in worldwide. In the present study, the combinations of egg albumen, pea protein, and gellan gum were optimized to fabricate an artificial steak for specific populations. The relationships among the different components on the texture profile analysis, sensory evaluation, viscoelastic properties, and thermal behavior were conducted. 3D printing food was an emerging issue, this study also investigated how to fabricated an artificial steak and mitigate the impacts of meat production.
Plant-based meat substitutes are products used to replace meat in the human diet. These products have developed from traditional whole-grain meat substitutes to products based on an advanced technology called 2nd generation meat substitutes. Increased market visibility of 2nd generation products raised questions about the products´ healthiness once they are classified by NOVA as ultra-processed, are allegedly high in salt and saturated fat, and might not be nutritionally equivalent to meat.
