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.
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.
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.
Up to now, creativity, ingenuity, time and more than a little luck have been essential for transforming a wild plant into a new food crop. Building on the understanding of gene function in Arabidopsis, the process of domestication can be rapidly accelerated.
Trade agreements can constrain or enable governments’ ability to implement food system-level actions aimed at improving nutrition and mitigating climate change. The technical and political aspects of trade agreements that interact with food systems are reviewed here, and the coherence between trade policy goals and public interest goals, such as nutrition and climate change, is discussed.
Diet and policy approaches to curb obesity and type 2 diabetes can be contentious and confusing. This Review synthesises state-of-the-art and emerging evidence on diet and health, reflects on policy and reconciles the evolution of the discipline of nutritional science with changes in dietary advice.
Advances such as machine learning may enable the full biochemical spectrum of food to be studied systematically. Uncovering the ‘dark matter’ of nutrition could open new avenues for a greater understanding of the composition of what we eat and how it relates to health and disease
A consistent global gridded multi-model assessment of wheat production under climate change points to large uncertainties arising from crop models, particularly in mid and high latitudes.
This Perspective builds on the concept of full-chain nitrogen use efficiency to propose policy interventions and criteria that target major actors in the agri-food chain.
