Do you ever think about how living in a city might affect your food choices? A clever study in China used a unique approach to find out. Instead of relying on guesswork, researchers took advantage of a resettlement program that was decided by a lottery. This made it possible to compare what happened to households that moved to towns versus those that didn’t, offering a fair test of whether city life changes what people eat.

Over three years, they noticed something interesting. Households that moved to towns started eating more and had a wider variety of foods in their diet. This included more of the essential nutrients that keep us healthy. But there was a downside. Some people began to overindulge in carbohydrates, like rice and noodles.

The key factor driving these changes? Better access to markets. It turned out that being able to buy a wider range of food made a big difference. This is a fresh perspective compared to some recent studies that didn’t find much of an effect from living environments. Instead, this research shows that the places we live can shape our diets in significant ways, highlighting the importance of supply-side factors.

But here’s the thing: we need to watch out for overconsumption. Just because we have access to more food doesn’t mean we should eat everything in sight. Balance is key.
