Cognitive restructuring in the context of nutrition primarily involves:

Cognitive restructuring in the context of nutrition focuses on changing how an individual perceives and interprets food choices. It is centered around the idea that by shifting the perception of foods from a binary perspective of "good" or "bad," individuals can foster a healthier and more balanced relationship with food.

This approach aims to encourage a more nuanced understanding of nutrition, helping individuals to see that foods can have varied nutritional benefits and that labeling foods strictly as good or bad can lead to unhealthy eating behaviors and an unhealthy mindset around food. This shift allows for flexibility and moderation in dietary choices, promoting a less anxious and more positive approach to eating.

The other options do not align with the principles of cognitive restructuring. While listening to others' opinions on food (the first option) may offer insight, it does not actively change one's personal perception of food. Counting calories meticulously (the third option) focuses on a quantitative aspect of nutrition rather than the cognitive or psychological aspect of how one views food. Avoiding all snacks (the fourth option) presents an extreme behavior which contradicts the goal of cognitive restructuring, which is to enable healthier and balanced choices rather than imposing strict rules or avoidance.
