Health Halo Effect
Definition
A cognitive bias in which a single positive health attribute of a food product (e.g., 'organic,' 'gluten-free,' 'low-fat,' 'plant-based') causes consumers to perceive the entire product as healthier than it actually is — often leading them to underestimate calories, sugar, or harmful additives.
Why It Matters
Research published in the Journal of Marketing Research found that consumers eat up to 35% more of a food labeled 'low-fat' compared to regular versions, because the health halo causes them to underestimate calorie content. This effect is exploited heavily: organic cookies are still cookies; gluten-free pizza is still ultra-processed; 'plant-based' meat alternatives can contain more sodium and additives than real meat. Always read the full ingredient list, not just the front-of-package claims.

Greenwashing (in Food)
InformationalA deceptive marketing practice where food manufacturers use natural-looking packaging (earth tones, images of farms, leaves), buzzword claims ('wholesome,' 'simple,' 'real'), or misleading certifications to create the perception of health and sustainability — without the product actually being significantly healthier or more sustainable than conventional alternatives.
No Added Sugar
InformationalA labeling claim regulated by the FDA meaning that no sugar or sugar-containing ingredient (e.g., fruit juice concentrate, honey, corn syrup) was added during processing. It does NOT mean the product is sugar-free or low in sugar — it may still contain high levels of naturally occurring sugars.
