Toddlers who consume two servings of dairy produce daily are likely to have healthier bones as teenagers, a study has revealed.

Researchers tracked the diets of children aged between three and five over 12 years. They found teenagers who had consumed two or more servings of dairy a day had higher bone mineral content.

"Although calcium requirements are highest during the teenage years, as the majority of bones are formed then, this study shows childhood is also an important opportunity to build bones," said Dr Judith Bryans, director of the Dairy Council.
