Using nutrition information thoughtfully

Nutrition needs and food choices can vary with age, activity, culture, budget, allergies, health conditions and personal preferences. These guides provide general educational information rather than individualized meal prescriptions.

For a diagnosed condition, a medically required diet, food allergy management or other complex dietary needs, consult a qualified healthcare professional or registered dietitian. Check product labels and local food-safety guidance when preparing and storing meals.
