Calcium for Pregnancy

Our body is unable to produce calcium, so it is an ‘essential’ nutrient that must be obtained through the foods you eat during pregnancy.

Why is calcium important?

Calcium is the most abundant mineral in the body. Almost all of the calcium in the body is found in the skeleton – more than 98% in fact. Therefore, a calcium-rich diet is very important in the development of your infant’s bones and in the maintenance of your own bones.

Calcium is also important in the building and maintenance of teeth and it plays a key role in our cells. In our cells it is involved in many processes, such as in the contraction of our muscles and in the transmission of signals in nerves.

When you are pregnant(and over 19 years old), your calcium needs are 1000mg a day. Pregnant women need to eat at least 3 serves of calcium-rich foods every day to meet their needs.


Calcium-rich foods

The main source of calcium is milk, cheese and yoghurt. Canned fish with edible bones, some nuts and a few fruits and vegetables also contain calcium. The amount of calcium found in the plant-based foods like fruits and vegetables is somewhat smaller than that found in dairy foods.

1 cup (250mL) of milk (whole, reduced fat or skim) 310mg
200g tub of natural or fruit yoghurt 340mg
40g (2 slices) cheddar cheese (mild, tasty, vintage) 310mg
¼ cup mozzarella cheese, grated 260mg
¼ cup ricotta cheese 150mg
½ cup tofu or bean curd 320mg
1 cup (250mL) of calcium-enriched soy drink 290mg
1 cup of vanilla ice cream 150mg
½ cup custard 130mg
100g (1/4 cup) canned pink salmon (bones included) 280mg
60g (1/2 small tin) canned sardines (bones included) 200mg
5 dried figs 190mg
¼ cup raw almonds 70mg
½ cup baked beans, canned in tomato sauce 50mg
1 cup of broccoli 30mg

Calcium at different stages in life

During childhood and adolescence, calcium is used to build and develop the skeleton and teeth. A calcium-rich diet is vital during this growth stage. As an adult, it is important to continue with a calcium-rich diet to maintain your bone strength. With age, calcium is lost from the bones. So eating 3 serves of calcium-rich food each day can help to keep your bones strong. One serve of calcium-rich food provides around 300mg calcium. Pregnant and lactating women need at least 3 serves of calcium-rich food each day.
