Healthy Weight Gain in Pregnancy

Cravings

Pregnancy cravings can start at any stage in your pregnancy. We are not entirely sure why cravings happen, but the most likely cause is changing hormones.

  • If you are craving safe, healthy foods, then you are safe to enjoy what you are craving. 
  • If you are craving unsafe foods, like cream donuts, sushi and raw meat or seafood, then it is very important that you do not eat these foods. Eating unsafe foods can increase your risk for stillbirth, or becoming very unwell yourself. 
  • If you are craving unhealthy foods, like cake, chocolate bars, fish and chips and pies then it is important you limit your intake of these as over indulgence will lead to weight gain.  

 

Some women crave non-food items, like chalk or dirt. If you find that you are craving things that are not foods, then you should discuss this with your midwife or doctor.

If you are craving unhealthy foods then it helps to try to understand why you are craving what you are craving. Think about the taste, texture, appearance and temperature of what you are craving. This might help you to find a healthier option.

For example: 

  • If you are craving strawberry ice cream, is this because you are craving something cold or creamy or the taste of strawberries? Could you try eating fresh strawberries or freshly opened yoghurt instead? 
  • If you are craving potato chips, is this because you are craving something salty or crunchy or plain? Could an alternative be wholegrain crackers, freshly made popcorn or a slice of grainy, crunchy toast with a salty topping like Marmite or Vegemite?

Changing Body Shape in Pregnancy

During pregnancy your body undergoes a number of changes to accommodate for the growth and development of your baby. Weight gain is normal and if you gain a healthy amount of weight then you should find that the weight you gained in your pregnancy is not too hard to lose following delivery. 

Some women find the changes their body is going through can be strange, confusing, worrying, or alarming. It is important to remember that weight gain in pregnancy is caused by a number of factors. 

The list below gives an idea of why you gain weight in pregnancy. This example is for someone who has a baby between 3 to 3.6 kg and who gains about 12.2 to 14.5 kg.

  • Baby: 3 - 3.6 kg
  • Growth of breasts: 1 kg
  • Growth of uterus: 1 kg
  • Placenta: 700 g
  • Amniotic fluid: 1 kg
  • Increased blood volume: 1.4 - 1.8 kg
  • Increased fluid volume: 1.4 - 1.8 kg
  • Fat stores: 2.7 - 3.6 kg

  • Remember, gaining weight in pregnancy is normal and to be expected
  • If you gain a healthy amount of weight, you should find the weight you gained is easier to lose than if you gain too much weight
  • Healthy weight gain will help your baby to grow to a healthy size
  • Focus on nourishing yourself with good foods that are full of nutrients, like fruits and vegetables and wholegrain cereals
  • Weight loss is not recommended in pregnancy

It is important that you talk to your midwife or doctor if you have any questions or need to discuss your concerns.

Food Safety in Pregnancy... Why is it so Confusing?!

I am often asked about food safety in pregnancy and I am the first to concede that it is an area full of confusion, and conflicting messages. 

During pregnancy, your immune system is less effective and this means you are more likely to get sick from food. Listeria is the 'bug' we are most concerned about while you are pregnant. This is because listeria has been linked to miscarriage, preterm birth and the death of newborn infants.

If you are infected with listeria you may not have any symptoms or, if you do, your symptoms may be like the flu, which means you may not realise that you have listeria at all. 

The main confusion people talk to me about relates to healthy eating in pregnancy, and particularly, what to eat when you are wanting to eat out. According to the guidelines, it is safe to eat a hot meat pie that you have purchased, but not a salad or a salad sandwich. This is confusing because it is the opposite of what we tell you to do with respect to healthy eating!

I wish that there was an easy answer I could provide regarding what is safe to eat when you want to eat out, but the reality is that the New Zealand food safety guidelines are very strict - I don't disagree with the guidelines at all; the impact of listeria can be devastating and is largely avoidable by not eating certain foods while you are pregnant.

Firstly, the most important factor is ensuring your stick to the basic principles of safe eating in pregnancy:

Food Safety in a Nutshell:

  • Wash and dry hands thoroughly
  • Clean, cook, cover and chill
  • Avoid high risk foods
  • Tell people who are preparing your food that you are pregnant
  • Make sure food is well heated to above 70 degrees celsius 
  • Be mindful of 'best before' and 'use by' date: do not eat food that is past these dates
  • If in doubt, do not eat it!
  • When you eat out, avoid the same high-risk foods you would avoid at home
  • Make sure any takeaway food is well cooked and prepared just before it is served to you
  • Avoid eating food from buffets, smorgasbords, salad bars or street vendors, as risks are harder to manage.

Some Ideas:

These are ideas that myself and my colleagues have come up with. These are guidelines only - make sure that what you choose to eat sticks to the guidance in the list above.

The Bottom Line:

  • If in doubt, don't eat it!
  • Pregnancy only lasts for 9 months - but the impact of unsafe eating in pregnancy can last a lifetime.

 

If you have any questions, you are encouraged to talk to your midwife or doctor.
