Gestational diabetes snacks

To help keep blood sugar levels nice and stable, it’s advisable to incorporate gestational diabetes snacks between meals. This can help blood sugar levels from dropping too low, which means you can avoid the liver dumping stored glucose into your bloodstream, spiking levels high.

Eating little and often of the right kind of foods will help achieve blood sugar levels which are more like gently rolling hills, than spikes and crashes of a rollercoaster

“I’m so hungry” vs “I have no appetite”

We all have different experiences in pregnancy and may even fluctuate between times where we could literally eat anything and everything in sight, to times where we can’t think of anything worse than trying to force some food down.

Gestational diabetes snacks are important in both instances and can be adjusted to suit.

Insatiable hunger strikes, then as long as you are outside of your test window, you can munch on your safe gestational diabetes snacks. This refers more to postprandial (post-meal) testing, where you eat and then test levels after 1 hr, 90 mins or 2 hrs. If you start snacking before your test your time, then this will obviously impact the result and may encourage you to overindulge in carbs which your body will struggle to process (you’ll see higher levels) which will not be an accurate account of how well you tolerated the previous meal.

If you really don’t feel like eating, then eat a very small little something just to keep you ticking over. Don’t feel you have to force down 3 big meals plus 3 snacks every day. Break it right down into smaller, manageable amounts.

Gestational diabetes snacks for pre-meal testers

Snacking may prove harder for those that have pre-prandial (pre-meal) test targets as eating too much, or too close before the test will obviously cause a rise in blood sugar levels.

Pre-prandial test targets are much lower than post-prandial and so you don’t want to be testing a pre-prandial target when your blood sugars are actually in a post-prandial state.

It’s important to make good choices that do not contain too much carbohydrate and to leave enough time for your body to process the snack before testing. 90 mins – 2 hours is a good amount of time.

Not enough time to eat snacks due to testing times

If you having difficulty waiting for 2 hrs after eating to be able to test and then snack, or because you are a pre-prandial tester, then speak to your diabetes team and discuss the possibility of changing to 1 hr post-prandial testing.

All our National guidelines (NICE, SIGN and HSE) have targets for testing blood sugar levels in gestational diabetes at 1 hr post-prandially and so unless there are other medical reasons to do so, there is no reason you couldn’t change to 1hr post-prandial testing: –

1.3.5 Advise pregnant women with any form of diabetes to maintain their capillary plasma glucose below the following target levels, if these are achievable without causing problematic hypoglycaemia:
fasting: 5.3 mmol/litre

1 hour after meals: 7.8 mmol/litre or
2 hours after meals: 6.4 mmol/litre. [new 2015]

NICE Guidelines, NG3 Diabetes in pregnancy – 1.3.5 Target blood glucose levels

Postprandial glucose monitoring should be carried out in pregnant women with gestational diabetes and may be considered in pregnant women with type 1 or 2 diabetes. ; In people with type 1 or type 2 diabetes, as long as hypoglycaemia can be minimised, aim to achieve blood glucose: ƒ

  • between 4 and 6 mmol/l preprandially, and ƒ
  • <8 mmol/l one hour postprandially, or ƒ
  • <7 mmol/l two hours postprandially ƒ
  • >6 mmol/l before bed.
SIGN Guidelines 116 – Management of Diabetes – 7.5.1 C GLUCOSE MONITORING

5.3.6 Blood glucose targets during pregnancy The following target values are recommended for optimum maternal and fetal outcome:

  • Fasting capillary glucose level: 3.5-5.0mmol/L
  • 1 hour post-prandial capillary glucose level: <7.0mmol/L (√).
HSE Guidelines for the Management of Gestational Diabetes Mellitus – 5.3.6

Be prepared!

Don’t get caught out. Just like you would (or will soon need to) with young children, you need to plan and take snacks with you! If you don’t then you may be faced with things that you know will cause high blood sugar levels. So plan and prepare to make sure you have suitable gestational diabetes snacks to hand!

Use food pairing to make sensible choices for snacks, so if eating something that is higher in carbohydrates (starchy carbs, fruit, a piece of chocolate) then add natural fats and protein to make it more tolerable e.g.

  • Crackers or crispbreads on their own will be hard to tolerate – add butter and plenty of cheese and you will turn it into a better gestational diabetes snack
  • Apple on its own may raise blood sugar levels too high, but add a handful of nuts or dip it in peanut butter and it becomes a more tolerable gestational diabetes snack

Don’t forget to have a drink with your snack. Hydration is also important for keeping blood sugar levels stabilised


Fruit is called natures natural sweets for a reason. Fruit contains high amounts of fructose which is a type of sugar. Fruit is also full of vitamins, minerals and fibre, but unfortunately, the high sugar content can make fruit a tricky food to tolerate with gestational diabetes.

Some ladies worry about reducing and limiting fruit on a gestational diabetes diet in case they are missing out on essential nutrients, but you can actually get any nutrient found in fruit from vegetables instead, just without all the sugar!

Some fruits are better than others. The lowest sugar (lowest GI) fruits are berries.

This picture shows examples of better fruits to try, but it is always advisable to pair fruit with fat to help slow down the release of sugar:

Bedtime snacks

Bedtime snacks can help with some peoples high fasting blood sugar levels, as they can help counteract the Dawn phenomenon or Somogyi effect. If you would like to know more about high fasting levels and these phenomena then please read more here.

Any of the snacks above may be suitable bedtime snacks, but if you find you are still struggling with high fasting levels then try a snack that is high in protein and natural fat as these are believed to have a better effect than those which include carbohydrates. Things like nuts, cheese & cooked meats are good things to try.

We often get ladies in our support group saying “I’ve tried a bedtime snack but it doesn’t work for me”, yet when asking what they’ve tried they’ve had fruit or toast e.t.c.

The best things to eat are high protein and natural fat. Bedtime snacks may take some playing around with to find what works best for you. As your pregnancy progresses and your insulin resistance increases, you may need to change to find things that work better and many ladies may need the extra help of medication or insulin to lower fasting levels.
