A comprehensive review of the constitutive nature, design approaches, structural properties and applications of food gels, pertinent to the food science, nutrition and health communities.
Transgenic corn expressing anti-inflammatory antibodies presents a new avenue for mitigation of the enteric disease coccidiosis, providing new possibilities for antimicrobial-free management of poultry diseases.
Poultry coccidiosis results in about US$3 billion global production losses per year, and is managed by prophylactic antimicrobial use. Lessard et al. have developed chicken feed based on transgenic corn for mitigating coccidiosis, resulting in reduced intestinal lesions and improved body weight and feed conversion in Eimeria-infected corn-fed animals compared to untreated controls. Corn-fed and salinomycin-treated birds had comparable outcomes, indicating potential for antimicrobial-free management of coccidiosis.
The gap between global supply and demand of omega-3 fatty acids is twice previous estimates. Opportunities to narrow that gap include increasing use of fishery by-products and reducing food waste.
The wealth of national food supply data, collected over decades by member states of the Food and Agriculture Organization, provides intriguing insights into regional transitions.
Tom Arnold has a wealth of experience in humanitarian and development approaches to combatting hunger. In his roles in food and agriculture, including with Scaling Up Nutrition and Task Force Rural Africa, he advocates for policy consistency and supportive relationships between civil society, business and government.
The global food system needs a radical overhaul to sustainably feed 10 billion people by 2050. Nature Food calls on scientists from the many disciplines of food to contribute their knowledge and experience to a collective dialogue on food system transformation.
Food systems are increasingly globalized and interdependent. Using food supply data from over 170 countries, Bentham et al. characterize global patterns of food supply change over five decades, highlighting the decline in the supply of animal source food and sugar in many Western countries, the increase in the supply of such foods in Asian countries and remarkably little change in food supply in the sub-Saharan Africa region.
Climate tipping points, such as the collapse of the Atlantic Meridional Overturning Circulation (AMOC), could drive significant structural changes in agriculture, with profound consequences for global food security.
Without a great food system transformation, the world will fail to deliver both on the United Nations Sustainable Development Goals and the Paris Climate Agreement. There are five grand challenges to be faced, by science and society, to effect that transformation.
Omega-3 fatty acids are important for the human diet and for some aqua and animal feeds. This study reports a supply gap, and using quantitative systems analysis identifies targets for increasing efficiency in the global omega-3 cycle.
Transformation of the food system at the national scale requires concerted action from government, business and civil society, based on sound evidence from the research community. A programme for transformation of the United Kingdom’s food system, for healthy people and a healthy environment, is described here.
Globalization transforms societies, economies and cultures. As a subject, food allows us to draw unique narratives on these transformations . The history of pie and mash, also known as the ‘Londoner’s meal’, is such a story of globalization.
