How many marshmallows can you eat before die?

The number of marshmallows one could eat before dying is not a fixed or precise value and can vary significantly based on individual factors, such as age, health conditions, body mass index (BMI), and the composition of the marshmallows. Overconsumption of any food, including marshmallows, can lead to health problems, but it is not possible to determine a specific number of marshmallows that would be fatal.
