Australian parents are setting their kids up for poor heart health after a study found two thirds consume too much salt and don’t get enough potassium.

A study of more than 650 Victorian primary school-aged children, published in journal The BMJ, found sodium levels in their urine were about twice that of potassium, reports 9 news.

For good heart health children need to be consuming equal amounts of these minerals, says lead author Carley Grimes from the Institute for Physical Activity and Nutrition at Deakin University.

“When we eat too much salt that actually raises blood pressure and that’s even been shown in children. Conversely if you eat higher amounts of potassium it helps to lower blood pressure and that’s also been shown in children,” Dr Grimes said.

“You look at that ratio of salt to potassium in the diet as a kind of quality marker for protecting blood pressure levels and cardiovascular health long term. The kids in this study were having more than double the amount of salt than potassium so that’s concerning for blood pressure and cardiovascular health long term,” she said.

For the IPAN salt study 666 children aged 4-12 were required to provide a urine sample. A parent and child food questionnaire was also used to report on the consumption of discretionary salt. Overall, the average intake of salt was 6.1 grams of sodium per day.

Major sources of sodium were bread, mixed cereal based dishes and processed meat, while nearly half of all participants’ daily sodium intake came from discretionary junk foods.

Four-to-eight year-old children were having 5.3 grams per day and five to 12-year-olds were having 6.6 grams per day.

“Four to eight year-olds should eat no more than 3.5 grams of salt per day and nine to 12 year-olds should be consuming no more than five grams per day,” said Dr Grimes.

“When we look at the whole sample compared to the dietary guidelines seven out of 10 children exceeded that recommendation and that recommendation is the maximum amount of salt they should be having, so it’s really quite concerning.”

The analysis also showed the ratio of sodium to potassium was out of balance at 2:4 respectively.

Dr Grimes blamed this on a lack of fruit and vegetables and excess salt being added to family staple foods like bread and cheese.

“You get potassium from milk, fruits and vegetables and children aren’t eating enough fruits and vegetables. We know that from our other national nutrition surveys,” Dr Grimes said.

To improve the sodium and potassium profile of school children Dr Grimes has called for food reformulation in Australia and says parents should be demanding this as consumers.

“Even if parents are doing everything right it’s still hard in the current food environment to get salt intakes down.

“If there is more demand for products that have less salt in them and there is awareness in the community I think that’s really important,” Dr Grimes said.

Do you closely monitor your children’s diet and how much salt and sugar they intake daily?

  • I notice there is no mention of some raw food containing natural salt. A list of fruit and vegetables that are high in potassium would have been helpful.
    It is not always the parents of their own child at fault. Sometimes children swap food at school.

  • I agree – we try really hard, but there’s salt in EVERYTHING.

  • Yes we’re mindful for salt and sugar intake and love our fresh fruit and veggies and milk products.

  • Yup, parents are responsible for setting the example….

  • Parents are responsible for what their children eat and should not allow so much salt in their diets. My lot mainly eat fruit and veggies as that is what they want.

  • It is a parents responsibility for what their child eats. I monitor my children’s salt, sugar and fat intake but we don’t go over board. A balanced diet with a few treats is fine.

  • Of coarse it’s the parents responsibility for their kids diets, I hardly ever add salt and when I do it natural mineral salt.

  • I agree that parents are ultimately responsible for their children’s diets and therefore their overall health.

  • Its really easy to say “feed them more fruit and vegies” but some days its more challenging than others.

  • I don’t think that my daughter eats too much salt or sugar. But I agree that a lot of health problems come from diet. And, with kids, parents are to be blamed.

  • I am so concerned about my kid’s health. We usually make dishes by adding low salt and sugar. So they are get use to this.
