Carry out a literature review on the issue and draw conclusions on the above claims with a title CITRIC ACID and CARBONIC ACID. Also include references and avoid plagiarism. [...] The claim that eating mangoes followed by drinking cold drinks can lead to the creation of a poisonous substance and cause death is not supported by scientific evidence. Mangoes do contain citric acid, which is a natural organic acid found in many fruits. On the other hand, carbonic acid is formed when carbon dioxide is dissolved in water, which is the case with carbonated beverages. However, the reaction between these two substances does not produce poison. In fact, both citric acid and carbonic acid are commonly found in various food items and are generally regarded as safe for consumption.
