According to Schlosser, what has been a trend observed in the types of foods offered by fast-food chains?

The trend of standardization and homogenization of menu items among fast-food chains, as outlined by Eric Schlosser, reflects how these businesses have focused on creating a uniform experience across different locations. This approach allows chains to ensure quality control and brand consistency, enabling customers to expect the same taste and menu offerings no matter where they are. Over the years, fast-food companies have increasingly adopted similar menus and cooking methods, often relying on mass production processes to maximize efficiency and minimize costs. Such standardization can lead to a lack of diversity in food options, which is a significant departure from the variety of offerings that might have been present in the past. This trend underscores the broader implications of consumer culture and globalization on food choices in the fast-food industry.

While increased variety of gourmet options, an emphasis on locally sourced ingredients, and the introduction of ethnic cuisines might have their place in some segments of the food industry, they do not capture the prevailing movement noted by Schlosser regarding how fast-food chains have typically operated in a standardized and homogenized manner.
