The implicit advice is to be wary of the 'plant-based' label in food, as it often leads to an increase in the consumption of ultra-processed foods (such as french fries) rather than a better intake of raw vegetables.

Dr. Gabrielle Lyon highlights a behavioral bias here that is well-documented in nutritional studies. Research, such as that published in the 'Journal of the Academy of Nutrition and Dietetics' (observational study), confirms that so-called 'vegan' diets are not automatically healthy if they are rich in ultra-processed products and refined sugars. Science validates the idea that nutritional quality (nutrient density) takes precedence over plant origin alone. It is, however, slightly exaggerated to suggest that this is the universal problem with all plant-based approaches, as many individuals use these diets to increase their intake of fiber and micronutrients. The analysis is therefore a useful reminder of the distinction between 'whole plant-based' and 'processed plant-based.' The current scientific consensus (meta-analyses on diet quality) supports the fact that reducing ultra-processed foods is a more effective pillar for health than simple categorization by origin (animal or plant).
