What key theme does Schlosser address regarding consumer awareness?

Schlosser emphasizes the importance of consumer awareness in shaping food choices and the overall food landscape. When consumers are informed about what goes into their food, how it is sourced, and the implications of these choices on health and the environment, they are more likely to demand healthier options from fast-food chains and manufacturers. This heightened awareness can drive change in the industry by encouraging companies to be more transparent and responsible. As consumers become more conscientious about their dietary choices and the impact of fast food on their health and society, they tend to prefer better quality and healthier alternatives, prompting businesses to adapt to these preferences. This key theme underscores the power of informed consumerism in leading to positive shifts in food availability and health outcomes.
