New analyses from the Global Burden of Disease group have combined the three categories of diet risk factors – Maternal and childhood undernutrition, High body mass index, and Dietary risks for non-communicable diseases (NCDs) – into a single risk of ‘Malnutrition in all its forms’. In 1990, this single risk contributed to 24% of the total global burden of disease. By 2017, it had fallen to 19% but it was still the top risk for all countries, usually more than twice the burden of the next biggest risk factor. In some regions (eg Western Sub-Saharan Africa), malnutrition in all its forms fell by up to 10 %-points due to substantial reductions in undernutrition, and only one region (Pa- cific island countries) increased in burden. The food systems within all countries are creating the food environments that sustain thesehigh levels of malnutrition. In middle-income countries, undernutrition has declined markedly in recent decades and has long been eclipsed by diet-related NCDs. In low-income countries, this pattern is also rapidly emerging. What determines the dynamics of the food systems and why are they so difficult to change? Three sets of feedback systems help to answer this question. First, thegov- ernance systems set the rules and economic incentives and disincentives for food businesses and people to operate within. Changing those operating conditions, such as though taxes on unhealthy foods or regulations to restrict marketing to children, to improve the health or environmental out- comes of the food systems often creates substantial (and often successful) push-back fromthe affected food industries. Second, the business system involves the food and food services being exchanged for money, but the health and environmental costs (externalities) are rarely factored into the transaction. Internalising those externalities raises fears of politically unpalatable loss of profits for business and higher food bills for consumers. The third set of feedback systems isthe supply/demand nexus. Consumer expectations and brand marketing creates dietary habits which are slow to change, even in the face of mounting evidence of health and environmental harms. Double- and triple-duty actions are actions that address these feedback systems, thereby reducing two or more of the negative consequences of food systems. Examples for strengthening gover- nance include reducing the power of commercial vested interests and strengthening the power of civil society in policy-making. Examples for changing business models include pigouvian taxes and transparent triple bottom line reporting. Examples for changing supply/demand dynamics in- clude health and environmental labelling of food and tighter marketing constraints. Such actions are, simultaneously, extremely difficult politically, uncertain in their outcomes, yet essential for achieving healthy, sustainable, equitable, and profitable food systems.

The proinflammatory cytokine inter- leukin 6 (IL6) induces hepcidin expression which may lead to decreased intestinal iron absorption. On the other hand, greater blood volume in OW/OB individuals may increase hemoglobin mass and iron requirements and confound iron biomarkers by hemodilution. Using stable iron isotopes, we have systematically studied iron metabolism in obesity. We have
