New research shows that New Zealanders are being fed much more salt in popular processed foods, than people in other countries.
Over 260 products, including fast food and breakfast cereals were compared as part of the research.
The research found New Zealand to be high amongst countries with the most salt added to food.
"In our modern society we consume about nine grams of salt a day which is far too much," says Rob Walker from the Dunedin School of Medicine.
The health group, World Action on Salt and Health, says a KFC fillet burger, has the highest amount of salt, nearly 3.7 grams, compared to the same burger in Australia and Malaysia.
There is more salt in Kellog's All Bran cereal in New Zealand than in America, but not nearly as much as in Canada.
And a six inch Subway fares worse in New Zealand, too, with nearly twice as much salt as its Finnish counterpart.
"Most people are not aware of just how much they are consuming about 80% to 90% of the salt in our diet comes through the processed food, what we add on with the salt shaker in our meals is really only a small proportion of our daily intake of salt," says Walker.
The study says it is hypocritical of manufacturers to make healthy claims about their products when salt is a major factor in cardiovascular disease.
Meanwhile, experts say reducing our salt intake by just a few grams a day reduces the risk of heart disease and stroke, and they are calling on manufacturers for a gradual reduction in the amount salt they add to foods.
