This project investigates how supermarket shopping habits are linked to differences in weight and health between households in the Netherlands. We know that people with lower income or education are more likely to experience overweight, but we still do not fully understand why. One explanation is that families differ in the types of food they buy: some purchase more fresh and healthy products, while others rely more on energy-dense snacks or sugary drinks. To study this, we will combine existing survey information from the LISS Panel with real purchase histories donated by participants from their supermarket loyalty cards (Albert Heijn and Jumbo). This offers a unique opportunity to measure actual food buying patterns over time, rather than relying only on memory or self-reports. The results will show which types of purchases most strongly explain differences in weight, helping to design policies that make healthy eating easier and more affordable.
