WELLINGTON (AFP)A New Zealand woman’s 10-litre a day Coca-Cola habit was a major factor in her death, a coroner found Tuesday, urging the soft drink giant to put health warnings on its caffeinated products. Natasha Harris, a 30-year-old mother of eight from Invercargill in southern New Zealand, drank huge amounts of the fizzy beverage for years before her death in February 2010, coroner David Crerar found.
