Many low-income countries deliberately pursue agricultural specialization to increase yields and thereby lift their population out of hunger and poverty. Trade is supposed to offset the implied lower diversity of food production and deliver a food supply that supports the health of their population. This study challenges this assumption. I investigate the link between the prevalence of overweight and agricultural specialization. Using a fixed-effects panel regression on data from 65 low- and middle-income countries over the period 1975-2013, I find that countries in which agricultural production is more specialized have a larger share of overweight women. The positive relationship is higher in countries with lower per capita income. The correlation is not statistically different from zero for the male population, which confirms existing empirical evidence that malnourishment tends to be more frequent for women than for men. My results suggest that there are negative health implications of agricultural specialization in poor countries.
