According to Dr. Gregory Scrinis, which phenomenon undermines how we think about food?

The phenomenon that undermines how we think about food, as explained by Dr. Gregory Scrinis, is the overly reductive focus on nutrients in food. This perspective diminishes the complex relationship we have with food by breaking it down solely into its nutritional components, such as calories, macronutrients, vitamins, and minerals. This approach can lead to viewing food merely as a collection of nutrients to be consumed for health benefits, rather than appreciating it as a source of pleasure, culture, and connection.

This reductive mindset can contribute to disordered eating patterns, such as chronic dieting or an obsession with "healthy" eating, which detracts from an intuitive understanding of hunger and fullness. In contrast, Intuitive Eating emphasizes listening to one’s body signals and recognizing that food has value beyond just its nutrients, promoting a more holistic and satisfying relationship with food.

The other options touch on relevant issues in food culture but do not encapsulate the core problem of overly simplifying food to its nutrient content, which is fundamental to Scrinis' criticism of current dietary approaches.
