More work is needed to reduce the excessively high salt intake of New Zealanders and to counter the resulting "very serious" health problems, Dave Monro, of the Heart Foundation, says.

Mr Monro, of Auckland, yesterday gave a talk in Dunedin on a new HeartSAFE initiative, involving the food industry and several other key groups, which aims to further develop voluntary salt reduction initiatives undertaken by New Zealand food companies.

His talk was on the final day of the Dietitians New Zealand conference, at the University of Otago St David lecture complex. More than 200 attended.

New Zealanders consume an average of 9g of salt each day, 3g over the recommended upper limit, and double the suggested dietary target.

Excessive salt intake contributes to higher blood pressure and other adverse health effects.

It has been estimated that reducing the intake of sodium, the harmful part of salt, by 25% would prevent nearly 1000 deaths a year from heart attack and stroke.

Mr Monro, the foundation food industry setting manager, noted that about 80% of average dietary salt intake among New Zealanders came from processed food.

Excessive salt consumption was "a very serious issue for New Zealanders" and was also a big problem in other developed countries, such as Australia and Britain.

"But the good thing is there has been some fantastic work done by the food industry that we can learn from and head towards more efforts in sodium reduction," he said in an interview.

In recent years, the foundation and bread manufacturers had worked together and voluntary steps by companies had resulted in the salt content of high-volume white bread being cut from 550mg per 100g of bread, to 450mg.

Other food companies had also made significant cuts in the salt content of other processed foods.

Facilitated by the foundation, HeartSAFE was a collaborative public-private venture that included food companies, the New Zealand Food Safety Authority, industry associations and individual experts in specific fields.

Mr Monro has a BSc in human nutrition and a postgraduate diploma in dietetics from the University of Otago.
