The role of research in global food and nutrition security

The present discussion document gives an overview of where European research can add the most value in relation to tackling food and nutrition security challenges and points to areas where we can expand our research potential. Moreover, it highlights the need to develop a governance structure that will allow sharing of best practices and facilitate the transfer of knowledge and innovation to feed the planet sustainably. It should stimulate a global discussion with stakeholders and the general public, ultimately shaping a legacy for Expo 2015.JRC.A.TF-EXPO 201

Arginine metabolism in rat enterocytes

Rat enterocytes exposed to L-arginine in the absence of any other exogenous substrate were found to actively metabolize this cationic amino acid. L-Arginine was converted to L-citrulline either directly in a NADPH-sensitive manner thought to be coupled with the generation of NO, or indirectly through the sequence of reactions catalyzed by arginase and ornithine transcarbamylase. A large fraction of L-citrulline and L-ornithine generated from exogenous L-arginine was released in the incubation medium. The production of CO2 and (poly)amines from L-arginine occurred at rates 2 and 3 orders of magnitude lower than that characterizing the net uptake of the cationic amino acid, and this despite the fact that enterocytes were equipped to allow the interconversion of L-ornithine and L-glutamate. It is concluded that the oxidative catabolism of L-arginine in eneterocytes is quantitatively negligible relative to its conversion to L-citrulline and L-ornithine.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Eating patterns and food systems: critical knowledge requirements for policy design and implementation

Eating patterns are important for building sustainable food and agricultural systems. This paper begins by presenting the main features of eating patterns worldwide. These eating patterns include the relative convergence of diets, more rapid food transition in emerging and developing countries, development of a more complex food chain, and substantial food losses and waste at distribution and final consumption stages. These patterns have negative consequences on health and the environment. The drivers of these patterns are examined to identify knowledge gaps, the filling of which should facilitate the design and implementation of actions and policies aimed at making food systems more sustainable
