Scientists conducted an experiment involving rodents and sugary soda, with some reports indicating that the rodents' cognitive abilities were impaired after consuming the soda for two months. However, the specifics of the study, including the type of rodents used and the exact effects observed, are not consistent across reports. The research may also have implications for human health, with some outlets suggesting possible links to cancer, heart disease, and weight gain, although the exact nature of these connections is unclear.
