Scientists have found that global warming may indirectly contribute to an increase in obesity. The study, published in Nature Climate Change, found that on hot days, people are more likely to choose sodas, juices and ice cream, leading to an increase in sugar consumption.
An analysis of more than 15 years of shopping data showed that each additional degree between 12 and 30 °C adds an average of 0.7 grams of sugar to the diet per day. This is particularly true for people on low incomes who already have limited access to healthy foods.
According to the researchers, under the “worst-case climate change” scenario, daily sugar consumption among the most vulnerable groups could increase by about 5 grams by the end of the century. It is important to note that this is a scientific prediction, not an absolute guarantee – models always have a certain level of uncertainty.
This additional burden can increase the risk of obesity, diabetes and cardiovascular disease. The researchers emphasize: the connection between warming and obesity is indirect. Increasing temperatures only create conditions that incline people to consume more sweets, but the final choice always remains with the person.
Scientists warn that global warming is increasing the already high burden on healthcare systems, as sugar is already one of the key factors in the obesity epidemic.
