Consuming food which contains magnesium like nuts is as important as intake of calcium-rich foods in building strong bones in children, a recent research has suggested.

A study of 63 children showed that the amounts of magnesium consumed and absorbed were important indicators of bone health. Intake of dietary calcium did not have a marked impact on total bone mineral content or density.
“We believe it is important for children to have a balanced, healthy diet with good sources of minerals, including both calcium and magnesium,” Dr. Abrams concluded.
Nuts, salmon, cocoa powder, rice, wheat and oats contain magnesium and children would do good to consume it.
