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?

Portion control is irrelevant: when comparing avocados, carrots, and chips, energy density is identical across all three and thus does not inform recommendations.

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.

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.

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.
