There is a specific case. One girl (from the states like) drank 4 liters of cola every day for a week (two). And she died. Brevity is not a sister of talent, apparently, yes tq
Half a glass is enough to choke. The question is not hard - to drink. And if you drink, I think that a liter for 10 people will already get problems, and then it already depends on his health in general.
I would answer this way. If you drink a huge amount of any liquid (it is absolutely not essential that it will be Coca-Cola or just water), which individually, again, will be life-threatening. If in one gulp, then it is unlikely that you will be able to die vomiting, which will not allow you to drink a lot. But if gradually and without being in the toilet, then the abundance of fluid you drink will cause an electrolyte imbalance, which can lead to heart failure and death. The number of liters, I repeat, is individual. The record holders drank 25 liters per day. In the case of cola, in addition to the liquid component, the high sugar content will be important. If the cola is dietary (light, for example), then the lethal dose of aspartame as a sweetener, which is metabolized into methanol, will be 40 μg / kg of human weight, in other words, 26.6 liters of diet cola.
The lethal dose of sugar is 29.7 grams per kilogram of body weight.
Let our "subject" weighs 80 kilograms.
1 liter of Coca-Cola contains approximately 100 grams sugar.
By simple calculations, we find a lethal dose of cola - 23.2 liters.
When the kidneys fail, then there will be a critical moment, a turning point for everyone, in this case. Here you just need to type 140 letters, but I really don't like it
