National soft drinks representatives have branded a global report that blames the industry for 184,000 deaths a year as inaccurate.

The study, released last week, claims the the deaths are from diabetes, heart disease and cancer caused by consuming fizzy drinks, fruit drinks, energy drinks and sweetened ice teas. One author of the report said: "Many countries in the world have a significant number of deaths occurring from a single dietary factor - sugar-sweetened beverages."

However, the Canadian Beverage Association and the American Beverage Association said the report, from the Friedman School of Nutrition Science and Policy at Tufts University in Boston, failed to connect the deaths to beverages.

"The authors themselves acknowledge they are at best estimating a presumed effect of sugar-sweetened beverage consumption, which is very different from demonstrating causation," the CBA said.

The British Soft Drinks Association said: "In no way does this study show that consuming sugar-sweetened beverages causes chronic diseases such as diabetes, cardiovascular disease or cancer."

The study based its estimates of consumption from 62 dietary surveys including 611,971 people taken between 1980 and 2010 across 51 countries, along with data on national availability of sugar in 187 countries and other information.

Earlier this year, the American Beverage Association said new US dietary recommendations went too far and lacked any scientific basis.
