".....Ten research priorities
Here we set out a new global research agenda for nutrition. It is aimed mainly at researchers, funders and governments, but has important messages for all stakeholders.
"Identify entry points for change. Food systems are dynamic; they comprise production, storage, transport and trade, processing, transformation and retail and the interactions between these. We need to understand how each part of the system can contribute in an integrated way to making high-quality diets more available, affordable and appealing. For example, how can we reduce food spoilage in storage, minimize nutrient losses during transformation and improve food quality with minimal processing?
Studies should involve multi-country and site-specific appraisals, qualitative research and mapping, and thorough analyses of value chains. Donors and funders should promote initiatives that are interdisciplinary, involve consumers and policymakers, and analyse which incentives cause actors in the food system to behave differently........
"......Agree on what constitutes a healthy diet. People do not choose nutrients, they select combinations of foods in differing amounts. Pairings of single foods and diseases are the basis of risk-factor analysis in global burden studies, but tell us little about diets as a whole. Although there are studies on the value of, say, the Mediterranean diet, there are few from low-income countries. And even the nutritional profile of many important indigenous foods remains poorly known.
A better understanding of dose–response relationships is needed. Is it better to eat a little of each food category frequently, or a large amount less often? Food researchers need to be more creative and research funders bolder in assessing the health implications of common combinations of foods...."
