Implementing Nutrition Care (cont’d.)
• Approaches to nutrition care
– Long-term nutrition intervention
• Plan must consider: current food practices,
lifestyle, and degree of motivation
– Implementing long-term dietary changes
• Determine the individual’s readiness for change
• Emphasize what to eat, rather than what not to eat
• Suggest only one or two changes at a time
![Page 5: NHHC chapter 14 ppt](https://reader030.fdocuments.us/reader030/viewer/2022033105/5873ccc81a28ab9d168b5721/html5/thumbnails/5.jpg)

specific to their particular medical condition
• Considerations: person’s age, literacy level, and
cultural background; learning style; etc.
