Our global food system has never been more advanced, yet in 2016 almost 1 billion people were hungry, 2 billion suffered from micronutrient deficiencies, and 2 billion were overweight or obese. Decades of placing the onus on consumer choice to improve nutrition and health has failed and the world is looking more broadly at how to achieve healthy and sustainable diets for all.
Agriculture and food systems are increasingly being recognised as key drivers of diet quality and nutrition. This then begs the question: how can agriculture be leveraged to sustainably contribute to better nutrition and health outcomes globally?
We make a unique contribution to this broad research theme through combining expertise in nutrition science, integrated assessment and scenario modelling at multiple scales. Members of our group regularly participate in multiple international committees.
The nutritional benefits of fish are multiple. Fish is a concentrated source of multiple highly bioavailable micronutrients including vitamins, minerals, essential fatty acids and high quality protein. The health benefits of fish consumption, including protection against chronic disease, and benefits for child growth and development are also well known. Fish therefore offers a unique opportunity […]
Insufficient growth during childhood is associated with poor health outcomes. Our work contributed to research published in Nature (Osgood-Zimmerman et al. 2018) that found that between 2000 and 2015, nearly all African countries demonstrated improvements in under-5 stunting, wasting, and underweight, the core components of child growth failure (see below figure). We contributed key data maps of […]
The outputs of agricultural systems are traditionally described in terms of yield per unit area (e.g. tonnes per hectare), where the main goal has been to maximise production. But this gives no indication of nutritional quality of the food produced. Innovative metrics to describe the nutritional quality of food production systems is a new and […]
Globally, approximately two billion people are overweight or obese. The global increase in obesity is a sign of deeper problems within the societal systems that are driving overconsumption, inequalities and societal problems. Obesity is the result of many complex systems, including: food supply, transport, urban design, business, socio-cultural, marketing, communications, education, health, trade, legal, economic, and […]
Fish are a well-recognised source of high quality protein and play an important role in diets, particularly for the poor in many regions of the world. Fish are also a key but under-recognised source of micronutrients such as iron, zinc, calcium, vitamin A, vitamin B12 and essential fats. The fish food system is undergoing rapid change, with […]
Malnutrition directly affects one in three people around the world, causing stunting, wasting or obesity. Malnutrition and diet are by far the biggest risk factors for the global burden of disease: every country is facing a serious public health challenge from malnutrition. Globally, there are agreed targets for nutrition, but despite some recent progress, the […]
