Artificial trans fat is omnipresent in the global food chain, but the medical consensus is that it increases the risk of developing cardiovascular diseases such as heart disease and stroke. Between 2007 and 2011, New York City and six other county health departments implemented bans on trans fat in restaurants. This column presents the first evaluation of the effect of these bans on cardiovascular disease mortality rates.

Diet-related chronic diseases are a major public health concern. Addressing this concern is a key government policy objective. This Vox Talk argues that the impact of these policies on diet and health outcomes depends on how consumers adapt their consumption behaviour and on how firms respond in terms of the prices they set and the foods they offer.

Whereas the Millennium Development Goal of reducing extreme poverty by half was achieved by 2010, the global hunger rate has only fallen by a third since 1990. Differences in survey design may account for part of this discrepancy. This column presents the results of a recent experiment in which households were randomly assigned to different survey designs. These different designs yield vastly different hunger estimates, ranging from 19% to 68% of the population being hungry.

Recently, there has been great concern among policymakers worldwide about rising food prices and increased food-price volatility. It is widely believed that oil and food prices have become closely linked after 2006, owing in part to a shift in US biofuel policies. This column presents evidence that challenges this conventional wisdom.

Africa is not achieving its potential in food trade, increasing the risk of widespread hunger and malnutrition. This column argues that the most serious problems for the continent are problems of political economy and barriers along the value chain. The good news is that, despite demand for food throughout Africa predicted to double over the next decade, governments can act now to overcome these problems. With a regional approach to food security, African governments can spur on benefits to farmers and consumers as well as job creation along the value chain of staples.
