Coca-Cola (and many other soft drinks) have so much sugar content that they need to add phosphoric acid to mask it, otherwise you'd probably vomit. Your pancreas controls your blood-sugar level and can get overworked if you say, drink 2 GALLONS of coke everyday, setting you up for adult diabetes. If one organ is strained they rest have to compensate; this lady's heart couldnt take it anymore.... sad but hey, it's the live we choose.
