What is one major health concern linked to fast food, according to Schlosser?

One major health concern linked to fast food, as highlighted by Eric Schlosser, is the prevalence of obesity and diet-related diseases. The fast-food industry has played a significant role in shaping dietary habits that contribute to these health issues. The high calorie content, combined with low nutritional value and large portion sizes, makes fast food a major factor in the rising rates of obesity. Moreover, this trend is associated with various diet-related diseases, including type 2 diabetes and cardiovascular conditions.

While the other options also represent valid health concerns—such as sodium content, heart disease, and trans fats—they are more specific aspects of the broader issue of obesity and related diseases. Schlosser emphasizes that the overall impact of fast food on public health is closely tied to its contribution to the increase in obesity rates, making this the most comprehensive choice in understanding the health ramifications.
