Which interpretation best justifies the recommendation to practice portion control with avocado despite its healthier fats when compared to a carrot and a potato chip?

• A. Portion control is irrelevant: when comparing avocados, carrots, and chips, energy density is identical across all three and thus does not inform recommendations.
• B. Recommend eliminating avocados entirely because any fat regardless of type is nutritionally equivalent to trans fat and therefore must be avoided, unlike carrots which contain no calories.
• C. Avocado contains more calories per gram than a carrot (higher energy density) so although its fats are healthier, a typical serving can contribute many calories; in contrast a potato chip is even more energy dense, so portion control helps prevent excess energy intake while still gaining nutrient benefits.
• D. Because avocado is a single food item, eating it alone always meets all nutrient needs and therefore portion control is unnecessary compared with whole vegetables like carrots.
