Preconception
The health of a mother and baby is influenced not only by diet during
pregnancy but also by diet before conception. Eating a healthy diet
before pregnancy will give your body a good store of nutrients for the
baby to draw on during pregnancy. The foetus is most susceptible to
nutritional imbalance during the first few months of pregnancy because
this is the time of most rapid development.
If you are very underweight or overweight, you should try to achieve
an acceptable weight for your height by a sensible and well-balanced
diet.
If you take the contraceptive pill, it is a good idea to come off and
use an alternative method of contraception a few months before
conceiving. This is because the pill can alter levels of some nutrients,
particularly vitamin B6, folate and zinc. Ensure that you have a well
balanced diet with plenty of fresh fruit, vegetables (especially green
vegetables) and wholegrain cereals. Try to avoid fatty foods, sweets,
biscuits and cakes.
Now is the time to make other healthy lifestyle changes and so stop
smoking, cut down on alcohol and drinks containing caffeine such as tea,
coffee and cola. Try a barley drink such as Barley Cup, or herb and
fruit teas instead.
If you find you are pregnant before you have had time to think about
preconception, then don't worry, there is still plenty of time to make
healthy changes to your diet.
Pregnancy
Pregnancy is a time when good nutrition is vital, for vegetarians and
non-vegetarians alike. It is a time of readjustment as well as growth.
The nine months are divided up into three divisions of three months each
called trimesters. Many women experience changes in mood, activity and
appetite with the different stages of pregnancy.
There is no truth in the old saying that pregnancy means eating for
two. The extra energy needed is only 200-300 calories a day for nine
months. This is equivalent to two slices of bread with margarine or a
jacket potato with baked beans or cheese. Some women do feel a lot more
hungry than this and if they are gaining weight at the right rate, they
should eat according to their appetite.
0-3 Months
Women usually feel different and may experience tiredness as well as a
feeling of sickness particularly in the morning (see advice on morning
sickness). Calorie needs are only about 100kcal more in the early stages
of pregnancy and some women do not experience much increase in appetite
until the end of this period.
3-6 Months
Appetite usually increases after the first three months and this
period requires about 300-400kcal extra calories a day. Extra calorie
need should be met by cereals, pulses, nuts and seeds, dairy products
(unless vegan) and starchy vegetables such as potatoes.
6-9 Months
The baby is maturing now and this is a time for easing up on activity
and preparing for the birth. The baby takes up a lot of space and may
press on the stomach, reducing the capacity for food. Many women feel
they need to eat small meals more frequently at this stage. Normal
weight gain during pregnancy is about 22 to 28 pounds or one and a half
to two stones (10-12.5kg). Weight gain often slows down during the last
few months of pregnancy.
Exercise
It is a good idea to do some form of exercise during pregnancy.
Antenatal clinics normally advise on appropriate exercise. Swimming or
gentle yoga are often recommended.
Nutrients
Fluid
You may find that you are more thirsty during pregnancy. This is
natural as fluid intake should increase. Never allow yourself to become
over thirsty and include plenty of fresh water, dilute fruit juices,
milk (soya or cow's) and herb teas. Drinks containing caffeine (tea,
coffee and cola) should be limited and alcohol should be avoided
altogether if po
