A person argues that eating an entire avocado is healthier than eating a small handful of potato chips because avocado has healthier fats. Which counterargument best uses energy and nutrient density concepts to guide a practical recommendation?

• A. Encourage replacing all solid foods with unlimited avocado because its fats will prevent any weight gain and are therefore safer than eating any number of chips or other snacks.
• B. Avocados and potato chips are nutritionally identical so the choice is only cultural; therefore no practical serving-size advice is needed and any amount consumed is equivalent for health outcomes.
• C. Recommend doubling the avocado portion and eating chips only if the chips are baked rather than fried because frying is the only determinant of poor health, not total calories or nutrient content.
• D. While avocado provides healthier fats and micronutrients, it is substantially higher in calories per gram than a carrot; compared to chips it is lower in energy density, but portion size still matters — recommend measured servings (e.g., half an avocado) so the person enjoys benefits without excessive calorie intake.

Answer: (D)
