Consumers focus on food types, not portions, when it comes to perceived healthiness
It's an age-old question: Is it healthier to focus on the type of food you eat or the portion size? Whatever the correct answer is, consumers tend to be more influenced by the perceived healthiness of a food (nuts over chocolate, for example), than a food's portion size. That's one of the findings in new study, to be published in the INFORMS journal Management Science, that also finds that this tendency to neglect food quantity in favor of food type can partly be mitigated by encouraging consumers to compare different portion sizes of food side-by-side.
