Tricks im Supermarkt: Einkaufen nach dem Ampel-Prinzip

Supermarkets are not neutral spaces. They are engineered environments designed to maximize sales, and the psychology behind their layout, lighting, and even the size of shopping carts directly influences what ends up in your basket. In this episode of the F.A.Z. Gesundheit podcast, host Lucia Schmidt speaks with Dr. Volker Manns, a sports scientist and nutrition expert, about how to navigate these traps and turn the supermarket into a "fitness center for nutrition." The core insight: shopping is a skill you can train, and the key is to move from being a passive consumer to an active, informed shopper.

The Supermarket as a Psychological Maze

The design of a supermarket is no accident. Dr. Manns explains that shoppers are almost always guided counter-clockwise through the store, a direction that feels less stressful and encourages longer browsing. The carts themselves are oversized, so a half-full cart feels empty, prompting you to buy more. Even the music, typically at 70-75 beats per minute, is calibrated to slow your pace and create a relaxed mood. Specific lighting is used to enhance products: a greenish hue makes vegetables look fresher, while warm, yellow light makes baked goods more appealing. The smell of fresh bread is often artificially dispersed to trigger an emotional, comforting response. The goal is to keep you in the store longer and make you buy on impulse.
