Dairy foods and calcium

yoghurt cupsDairy foods such as milk, yoghurt and cheese are a rich source of dietary nutrients. They provide a good source of dietary calcium and contain protein, vitamin A, vitamin B 12, magnesium, phosphorus, potassium, riboflavin and zinc. Table 1 shows the calcium content of some common dairy foods.

Average calcium content of dairy foods

Food Source Serve Size Calcium
Full cream milk 250mL 285mg
Skim milk 250mL 310mg
Natural yoghurt 200g 340mg
Low fat yoghurt 200g 420mg
Cheddar cheese 40g 310mg

Foods and beverages high in calcium may contribute to stronger bones and teeth. There is also some evidence that dairy foods and calcium play a role in the prevention of heart disease and weight management.

The evidence shows that milk and calcium (both dietary calcium and as a supplement) protect against bowel cancer.

Should I eat dairy foods?
Dairy foods should be eaten as part of a varied and nutritious diet to help maintain healthy bones and teeth. However for those who prefer to avoid dairy products, it is recommended that alternatives foods that are either a source of calcium or have added calcium are chosen. Cancer Council supports the Australian Dietary Guidelines, which encourage people to eat at least two and a half serves of dairy foods (milk, yoghurt and cheese) or alternatives each day. Cancer Council encourages people to choose reduced fat varieties.

Recommended Dietary Intake (RDI) of calcium for men and women

Gender Age Group Approximate serves/day
Men 19-70 years 2½ serves
>70 years 3½ serves
Women 19-50 years 2½ serves
>50 years 4 serves

In Australia, people don’t get enough calcium in their diet. It is estimated that more than 25% of men and 50% of women eat less than the recommended number of serves. Of concern are children and teenagers not receiving sufficient calcium while their bones grow and those older Australians who are at risk of osteoporosis.

What is a serve?
One serve of dairy equals:

  • 1 cup milk
  • 200g yoghurt
  • 40g hard cheese (roughly the size of a matchbox, or 2 slices)
  • ½ cup ricotta cheese

The following non-dairy foods are equal to a serve of calcium:

  • 1 cup calcium fortified soy or rice milk, or other cereal beverage with at lease 100mg added calcium per 100mL
  • 100g (about ½ cup) almonds
  • 60g sardines or ½ cup (100g) pink salmon with bones
  • 100g firm tofu
