Children who eat more than 60g of yoghurt daily have a better overall diet compared to those who eat none, a new study has shown.

The research, carried out by food scientists at the University of Reading and published in the European Journal of Nutrition, shows that among the 1,687 aged between four and 18 who provided dietary diaries, the highest consumers of yoghurt scored more highly on a Healthy Eating Index.

In particular, the children who on average ate around 100g a day of yoghurt – equivalent to around one small yoghurt pot per day – had significantly higher intake of vitamins A and C, and minerals including iodine from their whole . They also ate less processed foods including white bread, cakes and pastries.

Dr. Ditte Hobbs, from the University of Reading's Hugh Sinclair Unit of Human Nutrition, was lead author of the paper. She said:

"The findings are very interesting, showing a pattern between yoghurt consumption and an overall healthy diet which includes fruit, vegetables and fibre.

"Among the findings, we noted that among younger children aged 10 and under, those eating around 100g of yoghurt a day were consuming significantly less fat and salt than those who ate none."

The researchers also found that yoghurt consumption was low among secondary school-aged children, with fewer than one in three (31%) of 11-18 year olds in the study eating any yoghurt at all.

"The nutritional information reported by the more than two-thirds of secondary school-age children who ate no yoghurt doesn't make for happy reading," Dr. Hobbs said.

"Almost one in five was getting too little iodine from their diet overall, and one in six was not getting enough calcium."

While the new study only looked at sources of nutrients, and did not measure specific iodine or calcium deficiencies in individuals, researchers have expressed concern that the results may indicate that high numbers of children may not be getting enough of these minerals, which are important for good health.

Professor Ian Givens, Director of the University of Reading's Institute for Food Nutrition and Health, who co-authored the research, said:

"Research has repeatedly shown that dairy consumption among young people has been declining for many years, with a particular impact on amounts of iodine being consumed.

"Other studies have shown that there may be a relationship between iodine deficiency in pregnant women and lower IQ in their children. There is also a relationship between lower consumption of dairy among teenage girls and the risk of suboptimal bone development, which may increase the risk of problems such as osteoporosis in later life."

Health markers for children who took part in the study also show an association between good health and yoghurt consumption. Children who said they ate yoghurt had lower blood pressure and lower levels of glycated haemoglobin in their blood, which is used as a marker for diabetes.

Dr. Hobbs said:

"This study was not designed to find a causal link between eating yoghurt and , and there are a range of other foods needed to make up a healthy balanced diet. What we have shown is that children who eat yoghurt tend to eat better in general, and that eating can be part of a healthy diet for children."
