Calcium: a mineral for strong bones and teeth
Calcium and vitamin D are closely connected because we need vitamin D to help our bones and teeth make use of calcium. Dairy products are the best source of calcium.
One piece of research suggests that not having enough calcium may mean that some women are more likely to develop pre-eclampsia – but more proof is needed.
Foods rich in calcium (best first)
milk, yoghurt and hard cheese (soft cheeses, like cottage cheese and cream cheese, also contain calcium – but less than hard cheeses such as parmesan, Cheddar and Double Gloucester)
tinned fish – especially sardines and pilchards (including the soft bones!) and salmon
soya milk and tofu (made from soya) often have calcium added (check the labels – the normal level for cow’s milk is 120mg in 100ml)
foods made using white flour (which is fortified with calcium) – white bread, pizza bases and pastry
spinach and spring greens
chick-peas, kidney beans and tinned baked beans
sesame seeds and almonds
oranges and dried figs
Zinc: the fertility mineral
Zinc plays an important part in fertility (getting pregnant) and healthy pregnancy. It is also needed for growth and healing, and for good immunity to infections and disease. Meat, milk foods and seafood are all good sources of zinc. Some experts are concerned that the absorption of zinc by our bodies can be reduced by an excessive amount of fibre in our diets, and by unnecessary iron and folic acid supplements. This is one reason why it is important to consult your GP, midwife or pharmacist before taking any nutritional supplements during pregnancy.
Foods rich in zinc (best first)
meat – beef, lamb
sardines – especially good for zinc!
cashew nuts, lentils and chick-peas
wholemeal bread
other fish – smoked mackerel and prawns
hard cheese, milk and eggs
baked potatoes
sunflower seeds and peanuts
Iron: for healthy blood
Iron is needed to make haemoglobin, a pigment that is found in our red blood cells. Haemoglobin carries oxygen around our bodies. If our red blood cells are not healthy, the transport of oxygen around our bodies may not be good enough. We may begin to feel tired, breathless, dizzy and miserable. These are some of the signs of anaemia.
Doctors and midwives used to give all pregnant women supplements of iron routinely. We now know that unnecessary iron supplements may interfere with the absorption of other minerals, such as zinc. They may also cause constipation. It is usually better to prevent anaemia by eating more iron-rich foods. Iron supplements are, however, necessary to treat anaemia; your doctor or midwife will advise you as to whether you need an iron supplement.
Foods rich in iron (best first)
lean beef, lamb and kidney
dark chicken or turkey meat
fortified breakfast cereals
sardines
wholemeal bread
red lentils, chick-peas, baked beans, kidney beans
leafy vegetables – broccoli, peas, curly kale, spring greens, spring onions, spinach
cashew nuts, sunflower seeds
dried fruits – apricots, prunes and figs
baked potatoes
eggs
Tips on getting plenty of iron from your food
Eat some food rich in vitamin C with every meal – fresh fruit or vegetables. This will help your body absorb iron, especially from non-meat iron foods. Vegetables such as peas, broccoli and spinach contain vitamin C as well as iron – provided they are not over-cooked. Spring onions are also full of vitamin C and iron – a convenient no-cook snack!
Eat a variety of leafy green vegetables. (Spinach contains plenty of iron but this iron is not well absorbed by our bodies – so try other vegetables as well.)
Eat meat or fish with non-meat iron foods. This will help you absorb as much iron as possible from the non-meat food – for example, minced beef eaten with leafy green vegetables.
Drink tea and coffee between meals – rather than with your food. Both drinks contain chemicals that can reduce the amount of iron that your body can absorb from food. If you drink tea, have a cup an hour before your meal – or two hours afterwards.
Certain foods reduce the amount of iron that our bodies can absorb from a meal. One example is rhubarb!
What about salt?
Most of us eat more salt than we need. Processed foods – such as ham, cheese, bread, baked beans and biscuits – all contain lots of salt. Savoury spreads (like yeast extract and beef extract), crisps, olives and salted nuts are obviously salty foods. In the long term, too much salt in your diet may contribute to high blood pressure and related health problems later in your life.
During pregnancy, however, the situation is more complicated. Restricting your salt intake at this time has not been shown to reduce the risk of high blood pressure during pregnancy. But this does not mean that you should add extra salt to your food. Use salt to flavour your food, as you would normally.
When you have had your baby, you can try reducing the amount of salt you use in cooking and on your food. This will help when your baby starts taking solid food, since babies should not have any salt at all added to their food.
