WELLINGTON, New Zealand -- Experts say a New Zealand woman's 2-gallon-a-day Coca-Cola habit probably contributed to her death, a conclusion that led the soft-drink giant to note that even water can be deadly in excessive amounts.
Natasha Harris, a 30-year-old, stay-at-home mother of eight from Invercargill, died of a heart attack in February 2010. Fairfax Media reported that a pathologist, Dr. Dan Mornin, testified at an inquest Thursday that she probably suffered from hypokalemia, or low potassium, which he thinks was caused by her excessive consumption of Coke and overall poor nutrition.
Symptoms of hypokalemia can include abnormal heart rhythms, according to the U.S. National Institutes of Health.
Mornin said that toxic levels of caffeine, a stimulant found in Coke, also may have contributed to her death, according to Fairfax.
Harris' partner, Chris Hodgkinson, testified that Harris drank between 8 and 10 liters (2.1 and 2.6 gallons) of regular Coke every day.
"The first thing she would do in the morning was to have a drink of Coke beside her bed and the last thing she would do at night was have a drink of Coke," Hodgkinson said in a deposition. "She was addicted to Coke."
