The eminent protein sources among the vegetarian population include cereals and pulses that do not satisfy the Recommended Dietary Allowance (RDA) level.
Edible film, with unique biodegradable and renewable characteristics, is considered a potential alternative for petroleum-derived polymer packaging. The review provides an overview on the various aspects of edible film, such as the film formulation, source of materials, film characteristic as well as safety and regulations of edible film applications.
Brewer's spent grain (BSG), a protein-rich agro-industrial by-product, was used to develop edible film. The effect of pH and protein concentration on the physical properties of films were studied. While high pH favors the increase in the protein film's solubility, with increased tensile strength, elongation at break, and puncture strength; swelling capacity, water activity, and water vapor permeability (WVP) decreased with increasing pH. Increased concentrations of protein in films resulted in enhanced moisture content, mechanical properties, and water activity. Furthermore, the transparency values of films were increased by increasing pH and decreased by increasing the protein concentration.
Water resources and climatic conditions are important in maintaining sustainable agricultural production. Clarifying the important role of food linking the water and carbon cycles promotes the development of sustainable agriculture. Different food consumption patterns, especially one involving a high proportion of animal-based foods, indirectly affect water consumption and green house gas (GHG) emissions. A diet with a high proportion of plant-based foods is confirmed to benefit the environment; reducing the current overconsumption of animal-based foods can both benefit human health and alleviate the climate and water crises. Furthermore, the implementation of an environmentally friendly diet requires consideration of nutrients, cost acceptability, and local food production conditions.
Providing affordable access to enough healthy and safe food for an ever-more-affluent and growing world population has become more challenging in the face of climate change, rising income inequality a
Since the first-ever tax on junk foods was passed in 2014 the same-day purchasing patterns and trends on the Navajo Nation have improved and more than one-third of shoppers who were aware of the Healthy Diné Nation Act (HDNA) legislation attributed healthier shopping habits to the legislation, particularly related to beverages.
The authors conclude improved water, sanitation, and hygiene (WASH activities) were successful in contributing to improved dietary diversity in women. Interventions aimed at enhancing the diet and nutritional status of women during and after pregnancy should include relevant WASH components as essential elements in multisector nutrition programming.
Nutrient-sensitive approach for sustainability assessment of different dietary patterns in Australia
American Journal of Clinical Nutrition, Volume 115, 1 April 2022
The study presents a new approach to analyzing the relations between sustainability indicators, foods, and macronutrients and establishes that proteins, irrespective of the source of protein, are driving dietary environmental and economic impacts.
The results in this paper have implications for consumers and policy makers, as well as other food system actors. Consumers following individual strategies can make important contributions towards more sustainable food systems. To facilitate this shift, changes in food environments are needed and a coordinated action plan with coherent policies that targets a thorough redesign of the food system, including several of the proposed strategies, is needed to achieve large systemic effects. This could encompass suitable education measures, incentives, as well as rules for production, processing, retail, gastronomy, transport, and consumption.
Milk alternatives are compared from an environmental and nutritional point of view for more sustainable food systems.
