Food In Global History [PDF ebook] 

Social scientists study food in many different ways. Historians have most often studied the history of specific foods; anthropologists have emphasized the role of food in religious rituals and group identities; sociologists have looked primarily at food as an indicator of social class and a factor in social ties; and nutritionists have focused on changing patterns of consumption and applied medical knowledge to study the effects of diet on public health. Other scholars have studied the economic and political connections surrounding commerce in food. Here these perspectives are brought together in a single volume.
