Heat Gets Tastier: A New Study Links Rising Temperatures to More Sugar Intake in the U.S. — and Its Implications for Thailand
A newly released study finds that as heat worsens across the United States, Americans are reaching for more sugary beverages and, to a lesser extent, frozen desserts. The working thesis is simple but unsettling: climate change is not only warming the planet; it is nudging what people drink and how much sugar they consume. The researchers estimate the heat-related bump in added sugar translates to more than 100 million pounds of sugar each year, a shift that could compound health risks like obesity and diabetes, especially for communities already facing greater health disadvantages. The findings, drawn from weather data matched with consumer purchasing patterns across tens of thousands of households from 2004 to 2019, suggest a clear pattern: when temperatures rise, thirst and caloric sweetness follow, until it becomes uncomfortably hot and appetite for sugary foods wanes. Yet the overall trajectory is a stark reminder that climate-driven behavioral changes can have measurable consequences for public health.
