• Our bodies contain about 1kg of calcium and 99% of it is found in our bones and teeth.
• Most people should be able to get enough calcium through healthy eating.
Which foods are calcium rich?
• Dairy products such as milk, yoghurt and cheese.
• Green leafy vegetables such as curly kale.
• Bony fish such as sardines and pilchards.
• Dried fruit such as apricots and currants.
Why do we need Vitamin D?
• We need vitamin D to help our bodies to absorb calcium.
• The best source is sunlight.• You should be able to get enough
vitamin D through diet and by enjoying an active, outdoor lifestyle during the summer months. Don’t forget to be safe in the sun!
• Vitamin D can also be obtained from a small number of foods in our diet.

Put bone in the bank, now!
• During childhood, when the
skeleton is growing, we need to
build bone strength.• By ‘putting bone in the bank’ we will have strong
bones for when we naturally start to lose bone strength when we are older.
Why should we exercise?
• Bone is living tissue which
reacts to weight-bearing
exercise by growing stronger.
• Weight-bearing exercise
means any exercise where
you are supporting the weight of your own body.
Sport
• Team sports like football,
netball and hockey are good
for bone building.
• Tennis is another high impact but enjoyable sport that builds bone strength.
Exercise
• Jumping on the spot or skipping is good for children’s bones. Aim for 50 jumps a day or skipping for 5 minutes every day.
• Exercise to music classes, like aerobics, circuit training and boxercise will boost your bone strength.
• A 20 minute jog 3 times a week is good for building bone in both hip and spine in younger people.
Vitamin D
• The sunshine vitamin. We get 90% of our vitamin D from the sun.
