Metal In Local Groceries Can Increase The Risk Of Neurological Problems In Children

Exposure to calcium at low levels can increase the risk of decreased bone density and kidney dysfunction.

Now, a survey carried out at Edith Cowan University shows that many children may be getting more than the recommended levels of calcium, magnesium and nickel.

"For some of the metals we examined there is limited data worldwide on children's dietary exposure, so it is difficult to compare," said Dr Anna Callan, in a news release. "But we know that for many persistent chemicals in the environment, including metals, diet forms the major exposure pathway for people who don't smoke or who aren't occupationally-exposed."

For the study, researchers found that calcium levels in children eight years and up exceeded the European Food Safety Authority guidelines, while nickel and manganese intake was higher in young children than those reported in international studies.

Researchers found that low levels decreased bone density and kidney function, leading to manganese exposure as well as an increased risk of neurological problems that can cause hyperactivity.

"A healthy, balanced and varied diet is important for everyone, and especially children," Dr Callan added.
"Eating a variety of foods will help to minimize the risks of metals exposure.

"And practicing good hygiene, such as washing your hands before eating and washing fruit and vegetables to remove traces of soil, may also reduce exposure."
