 Meals and snack ideas to help you get your calcium …

  • Start the day with cereal (calcium-fortified) with milk or a milk substitute (calcium-fortified).
  • Use tinned sardines or pilchards (with the bones) instead of tuna in a sandwich or on toast.
  • Have a stir fry including tofu, broccoli spears and chopped nuts for lunch or dinner.
  • Add yoghurt/soya yoghurt to fruit as a pudding or use milk or a milk substitute (calcium-fortified) to make custard and milk puddings.
  • Try a glass of low-fat milk as a snack or to help rehydrate after exercising.
  • Don’t forget that low-fat dairy products have as much and often more calcium than the full-fat versions.
  • Remember to check non-dairy sources have added or are ‘fortified’ with calcium.

Vitamin D helps the absorption of calcium from foods. Foods rich in vitamin D include: oily fish, margarine and fortified breakfast cereals but you cannot get enough vitamin D from food alone. Most of our vitamin D is made by the action of sunlight on the skin so make sure to take advantage of this by going out of doors regularly. Young babies should take a vitamin D supplement providing 8.5-10mcg Vitamin D unless they are drinking more than 500ml formula.

 Are calcium supplements necessary?

If you think you or your child are not meeting your calcium requiements, discuss the need for supplements with your dietitian.
