Eating healthily during pregnancy helps baby's growth,
development and well-being. Not only
must you eat well, but
you need to eat carefully, avoiding unsafe
foods, for both you and your baby's well-being. But has
your internet surfng left you confused?
Even the most
well-trained of us can still be mystified about
what can be eaten
during pregnancy and what can't. Accessing
consistent advice or making an informed decision can be
confusing. I've gathered some tips that might
help to clarify the
issue and leave you feeling more confident in
those early stages of
parental responsibility.
Do I have to give
up Camembert
cheese?
Well, that depends on a few things. There
are two potential issues with soft
cheeses, firstly the
risk of listeria infection and secondly the bacteria that may grow
on the surface. But all
is not lost: if the cheese is made from pasteurised milk and
is cooked you can still enjoy
a little.
So what is
listeria?
Listeria monocytogenes infection can cause a mild unwellness during
pregnancy. However, it
can lead to miscarriage, stillbirth, premature birth or issues
with the foetus.
High-risk foods include:
- Smoked fish, including mussels, oysters and raw fish.
- Pre-prepared salad, including coleslaw (because of the mayonnaise).
- Pre-cooked meat products that do not require further cooking, such as pâté
and deli
meats.
- Unpasteurised milk and products made from it.
- Soft-serve ice-cream.
- Soft cheeses, largely due the to surface moulds, though if they are
well-cooked and hot
they are considered to be safe.
What about
fish?
One of the concerns about eating fish is
exposure to toxins, namely mercury,
which can be dangerous to the foetus. So,
while the dietary
guidelines recommend one to two fish meals a
week, this can vary depending on the type of fish. Fish
such as billfish (swordfish/broadbill and
marlin), shark/fake,
orange roughy and catfish are in a league of
their own - there are clear limitations on consumption of these
fish.
Food Standards Australia New
Zealand (FSANZ) advises
that pregnant women, women planning pregnancy
and young children
continue to consume a variety of fish as part of
a healthy diet but limit their consumption of certain species, which
are listed below. Keep in mind that this
advice is based on fish
in Australian and New Zealand waters and
populations, so if you are purchasing fish from other
regions this may not be
relevant.
So how much fish is safe? According
to Food Standards,
pregnant women should:
- Limit to one serve (150g) per fortnight
- billfish (swordfish, broadbill and
marlin) and shark
(flake), with no other fish eaten in that fortnight.
- Limit to one serve (150g) per week - orange roughy (deep sea perch)
or catfish, with no
other fish eaten that week.
- Don't worry if you've had the odd meal of fish with high levels of mercury. It's
only a potential
problem if you eat that type of fish regularly, as this can cause a
build-up of mercury in
your blood.
Is a coffee or a cuppa
safe?
Now, few would tell
you that you have to
give up your one a day coffee or tea, however, a word of caution is
warranted if you are a
heavy drinker of caffeinated drinks. Alertness is a good thing
at relevant times of
the day. However, if you are finding pregnancy or baby is
keeping you awake
already, you may need to look at either timing or amount of
caffeine-containing
drinks.
More
importantly though, there has been some research suggesting
that excessive intake
of caffeine increases the risks of miscarriage.
Recommendations put a
safe level at two cups of coffee and four cups of tea a day. 'Energy' drinks
are not recommended
during pregnancy as some can have very high levels of
caffeine and may
contain ingredients not suitable for pregnancy. Don't worry if you
have been
over-indulging, the evidence is still unclear and of course everyone and
every pregnancy is
different.
Tips to reduce your caffeine intake
and its
effect:
- Opt for decaffeinated drinks
(ideally, if it is
coffee, check it is steam-decaffeinated to reduce any exposure to
toxins)
- Consider de-tannininsed teas. Green
tea, for example, has
almost 30% more tannin that
as a diuretic can leave you feeling very thirsty.
- Don't forget to account
for other caffeine-containing drinks such as
hot chocolate, cola, and some
soft drinks.
- Check with your health
food shop for herbal
teas that are suitable during pregnancy, or opt for the safer
varieties such as
peppermint, lemon or chamomile.
- Ensure you drink plenty of
water and other healthy
beverages.
What about the odd
tipple?
There is now clear evidence that consuming
alcohol during pregnancy can affect foetal development, as it's
linked to low birthweight, miscarriage and other serious concerns.
Most agencies have updated their recommendations to total avoidance
of alcohol during pregnancy.
Reducing allergy in the family
In the past, avoiding allergy-causing foods was
thought to be a good way to reduce the risk of your child
being allergic. While research doesn't support that altering your
diet while pregnant will reduce this risk, there is plenty of
anecdotal evidence. The important thing to remember is that if
anything is removed from the diet you should replace it with a
healthy option. Each food group has specific nutrient properties,
so it is important to ensure you maintain a balanced diet.
Salt
Latest estimates suggest that we are eating
around 6g or more of salt a day in Australia and around 9
grams in NZ (3g is about a teaspoon), and that ideally we should
get this figure under 4g a day (1600 mg of sodium, salt being a
combination of both sodium and chloride). Most of the salt we
consume comes from processed foods (around 65-75%). Low-salt foods
(foods with up to 120 mg of sodium per 100g of food) are standard
recommendations for children and adults. Packaged foods with less
than 120mg per 100g are a rarity, so monitoring your intake of both
salt and processed foods during pregnancy is likely to be
beneficial.
Sugars
Many natural foods contain simple
carbohydrates/sugars and each simple sugar has an important
function. For example, fruit sugar (fructose) aids recovery after
exercise; breastmilk has a simple sugar called galactose, which
with lactose is important for immunity; and blood sugar (glucose)
fuels our brain. So to say that all sugars are bad is
simply not true. What we do need to take care with is how much
simple sugars represent of our daily diet (up to about 10% of
calories can come from simple
sugars).
The least-desirable simple sugar is added sugar, such as common
table sugar (sucrose). Added sugars tend to provide calories (or
kilojoules) without offering other nutrients such as vitamins,
minerals and dietary fibre. Calories derived from these sugars are
often referred to as "empty". When you are
pregnant quality nutrient dense foods is your best
option.
A nutrition panel is a great
way to determine the amount of simple
sugars in a product. Grab a cereal packet. Using the
100g column, note the difference between the "sugars" figure
(represents all sugars, naturally occurring and added) and the
"total carbohydrates" figure (all carbohydrates). Subtract the
sugars figure from the carbohydrates figure; the resulting number
represents complex carbohydrates (or "not simple sugars"). The
greater this figure the more likely the cereal is a healthier
option (at least in this respect). You are likely to find that many
breakfast cereals contain a very high percentage (85%) of simple
sugars.
Trans fats
Trans fats act in a similar way to saturated fat in the
body: they increase the bad cholesterol (known as LDL cholesterol
or low-density lipoprotein) and also increase the risk of heart
disease such as atherosclerosis. But trans fats go one step further
than saturated fat - they also lower the good cholesterol (HDL).
HDLs mop up fat in the body for excretion, so it's a double whammy.
Therefore, while saturated fat in excess can pose a health problem,
in appropriate amounts it is essential for life. However, trans
fats, to the best of our knowledge, perform no health function;
instead they have the potential to do significant
damage.
Levels of just 2% of
trans fats (of our total energy intake) appear to significantly
affect health.
Sadly, in Australia and New
Zealand, manufacturers are not required to note the presence of
trans fats in their products unless they make a claim about
cholesterol or fatty acids. No claim, no
information!
Tips to reduce your trans fat
intake:
- Limit your use of processed meats, for example salami
which has one of the highest levels of trans
fats.
- Currently the levels of trans fats in fast foods and
donuts is jiggling about. The increasing awareness of consumers has
seen a drop in the levels of trans fats in many of the usual
suspects, ideally check government watch dog sites for the latest
as new reviews are released regularly.
- If you choose to eat margarine, opt for brands that note
less then 1% trans fats on the label and are low in saturated
fat.
- Limit the amount and regularity of takeaway food and
deep-fried food.
- Reduce packaged foods.
- Limit or avoid cakes, biscuits, donuts etc.
- Reduce foods with "hydrogenated" or "partially
hydrogenated" vegetable oil as an ingredient, biscuits are high on
this list, so read ingredients labels.
- Opt for natural spreads made from original whole foods;
for example, 100% almond paste, avocado, hummus,
banana.
What's the take home message?
The real message from this is not that eating is tricky
but that the simple things can sometimes be hardest to see and do.
A good diet is one that is rich in a variety of whole, fresh foods,
lots of fresh produce and foods resembling their original
state.
