Nutrition: Concepts & Controversies, 12e Sizer/Whitney
2
Learning Objectives Discuss how a toddler’s nutritional needs differ from an adult’s needs. Distinguish among a food allergy, food intolerance, and food aversion, and describe how they can impact the diet. Explain ways in which a teenager’s choice of soda over milk or soy milk may jeopardize nutritional health.
3
Learning Objectives Discuss the importance of physical activity in the later years. Outline food-related factors that can predict malnutrition in older adults. Design a healthy meal plan for an elderly widower with a fixed income. Describe several specific drug-nutrient interactions and name some herbs that may interfere with medication.
