Fact: The more salt you eat, the greater the risk of high blood pressure and having a stroke, with crisps and savoury
snacks significant culprits according to new research commissioned by the Stroke Foundation of New Zealand.
Stroke Foundation Chief Executive, Jo Lambert, says the government and food manufacturers need to do more to slash the
salt in processed foods and reduce the risk of stroke.
“Reducing salt will help combat the 75 percent of strokes that are preventable. It’s disheartening to find only half the
foods tested in our study met voluntary targets for salt content. Some savoury snacks contained over half a teaspoon of
salt per serve, which is more than 50 percent of someone’s recommended maximum daily intake,” she says
“Food manufacturers must consider the health of their customers, and the government must think more about stroke
prevention through salt targets, rather than the public health system being the ambulance at the bottom of the cliff,”
she says.
Analysis of 888 crisps and savoury snacks sold in New Zealand between 2013 – 2019, found huge variation with some snacks
containing 360 times more salt than similar products. Jo says this variation highlights the feasibility of reducing the
amount of salt in snack foods.
“Some manufacturers have made real progress to reduce salt in their products, but this isn’t happening across the board.
The government needs to get more hands-on and set targets for food reformulation, that all manufacturers are strongly
encouraged or required to reach,” explains Jo.
Each year, approximately 9,500 New Zealanders experience a stroke, costing the New Zealand economy $1.1 billion. Anyone
who cuts down their salt consumption will help reduce their risk of stroke, while also reducing the huge burden on the
health sector and economy.
“This research shows once again that increasing our efforts to reduce the amount of salt in processed foods can improve
everyone’s health,” explains Jo.
While we wait for the government to take action on processed food manufacturers, consumers are encouraged to eat more
whole foods and vegetables instead of salty crisps and savoury snacks. If they do treat themselves, we encourage them
all to look for low salt options (less than 520mg of sodium per 100g of food).
