Thematic Support - Nutrition Planetary Health

非洲和南亚的低收入但新兴的国家受到营养不良所谓“双重负担”的困扰：生长衰竭和随之而来的微量营养素缺乏风险，以及导致糖尿病和高血压（高血压）的超重和肥胖水平不断上升。每一项都降低了人口的健康和福祉，阻碍了国家的发展。针对这些情况制定解决方案需要详细了解原因。事情往往不像看起来那么简单。例如，在确定儿童是否缺铁方面，感染至少与饮食中缺乏铁一样重要。同样，在生命后期出现的许多健康状况在前几代人和胎儿发育的最初几天就有其根源。我们的研究旨在了解饮食如何影响生长和疾病，从而设计更好的途径来改善低收入国家的人口。我们最近启动了一项新的地球健康研究方案，以应对人口增长、气候变化和生态系统退化日益严重的威胁。我们的工作旨在就优化粮食系统、农业和土地利用投资的战略向各国政府提供建议。

Low-income but emerging countries in Africa and South Asia are afflicted by the so-called ‘double burden’ of malnutrition: growth failure and the attendant risks of micronutrient deficiencies, and increasing levels of overweight and obesity that cause diabetes and hypertension (high blood pressure). Each of these reduces the health and well-being of the population and inhibits national development.Developing solutions to these conditions requires a detailed understanding of the causes. These are often not so simple as they may seem. For instance, infections are at least as important as poor dietary sources of iron in determining iron deficiency in children. Likewise, many health conditions that emerge later in life have their origins in prior generations and in the very first days of fetal development. Our research seeks to understand how diet affects growth and disease and thereby to devise better routes to improve population in low-income nations.We have recently started a new programme of research in planetary health in response to the growing threat of population growth, climate change and degradation of ecosystems. Our work is aimed at advising governments on strategies to optimise their investments in food systems, agriculture and land use.
