The Dietary Guidelines for Americans provide a variety of information related to nutrition and health, including:
- How to handle food safely
- How to plan a low-sodium diet
- Guidance on calculating caloric needs and understanding food portions
- Recommendations for daily servings of food groups, including grains
While all the options you've listed include useful information related to nutrition, the primary focus of the Dietary Guidelines is on overall healthy eating patterns and lifestyle recommendations rather than specific calculations or handling methods. However, safe food handling is a crucial aspect covered in the guidelines.
So, the most directly relevant option is “how to handle food safely.”
