Sex Differences in Food Preferences of Hadza Hunter-Gatherers

Food preferences are important for understanding foraging choices. In studying human foragers rather than other animals, we have the advantage of being able to ask them which foods they prefer. Yet surprisingly, no studies of systematically collected data exist on human forager food preferences. The Hadza of Tanzania are full-time foragers in an area where the hominin record extends back to 3-4 million years ago, so their diet is very relevant for understanding the paleo-diet. Here, we report on their food preferences, elicited with photographs of species within the five major food categories in their diet: honey, meat, berries, baobab, and tubers. There were sex differences in the ranks of two food categories: meat and berries. While male and female ranks agreed on the other three food categories, females ranked berries second and meat fourth, whereas males ranked meat second and berries fourth. Theses similarities and differences are interesting in light of the fact that the sexes target different foods. We discuss the implications of Hadza food preferences for the origin of the uniquely human sexual division of foraging labor

U.S. DEMAND FOR MILD COFFEES: IMPLICATIONS FOR MEXICAN COFFEE

While the U.S. remains the world's largest coffee importer, consumption of the good has dramatically changed in the past few decades. This study evaluates the influences of U.S. consumption habits, prices of coffees by origin, prices of near substitutes, U.S. income, the ICA, and NAFTA on U.S. consumption of three categories of Arabica coffee- Colombian milds, Mexican and other milds, and Brazilian. Results indicate that U.S. consumption of Mexican coffee is sensitive to its own price; price of Colombian coffee, which appears to be its largest competitor; and ICA controls. Under NAFTA, Mexico appears well positioned to gain increased U.S. market share of shade-grown mild Arabica coffee
