Why Oats and Frozen Fruit are Great for Diabetes Management

Oats: These fibre superstars are low on the glycemic index (around 50-55 depending on what type you choose). They release their sugars slowly into your bloodstream which helps to prevent blood sugar spikes. Plus, they’re rich in beta-glucan, a soluble fibre linked to improved blood sugar control and insulin sensitivity.

Frozen Fruit: They pack a punch of vitamins, minerals, and antioxidants without the added sugar found in some flavoured yoghurts or breakfast cereals. The freezing process even intensifies certain antioxidant properties, making them a true nutritional powerhouse. Plus they are a budget-friendly way to enjoy your favourite fruit all year round

However, I am aware that oats can be tricky for some managing diabetes and we have definitely had periods where they have been tricky for us to get the bolusing right. All I would say is to persevere and find the right strategy for you as the health benefits and satisfaction make them well worth teh extra effort!

But this recipe isn’t just for diabetics!

  • Ready in Minutes: Prep the oat mixture the night before, and wake up to a creamy oatmeal breakfast waiting for you! No more rushed mornings or unhealthy choices.
  • Endless Flavor Combinations: Mix and match your favourite frozen fruit and berries, try different plant-based milk like almond milk, soy milk and even coconut milk and even add a scoop of protein powder for an extra boost. 
  • Adaptable for Dietary Needs: This recipe is naturally gluten-free with certified gluten-free oats, and easily made vegan with plant-based milk and yogurt.
  • Meal Prep Magic: Whip up a big batch on Sunday night and portion it out into mason jars for a perfect make-ahead breakfast throughout the busy week.

What Oats should you use in overnight oat recipes?

close up of oats

In overnight oat recipes, it’s best to use old-fashioned rolled oats (well that’s my personal preference). They absorb liquid well and soften overnight, creating a creamy texture. however ultimately, the best oats to use for your recipe are:

  • The ones you enjoy most! Experiment with different textures and flavours.
  • Compatible with your dietary needs. Choose gluten-free oats if needed
  • Fits your lifestyle. If time is tight, rolled oats offer a good balance.

When it comes to the “healthiest” oat for your overnight oats recipe, there’s not a single definitive answer! Each type offers unique qualities, and ultimately, the “best” one depends on your individual preferences and priorities. Here’s a breakdown of the main available types of oats:

Steel Cut Oats or Pinhead & Course Oats:

  • Arguably the “healthiest” of all the oats due to the minimal processing and they retain the most fibre and nutrients
  • However, they need to be cooked or left to soak before using and they will require more liquid. They also result in a chewier texture.

Rolled Oats or Old-Fashioned Oats:

  • They are a good middle ground between health and convenience as they are minimally processed, retain a good fibre content, and cook faster than steel-cut oats.
  • My preference is to buy organic rolled oats as they have fewer chemicals and pesticides.

Quick Oats

  • They cook or absorb liquid the fastest but are more processed and potentially have a higher glycemic index, which might not make them the ideal choice when considering blood sugar management

Instant Oats:

  • These are the least desirable option as they are they are the most processed, often containing added sugars and sodium.

Considerations for Type 1 Diabetes:

  • Glycemic Index: Since managing blood sugar is crucial, consider the glycemic index (GI) of each oat type. Steel-cut and rolled oats generally have lower GI than quick oats.
  • Fibre Content: Opt for oats with higher fibre content, as it slows down digestion and sugar absorption, benefiting blood sugar control. Steel-cut and rolled oats win again!

Ground Flax seeds

  • Boasting high levels of omega-3 fatty acids and fibre

Greek Yoghurt

Recipe Tips and Substitutions

  • For thicker oats, use less milk or add extra chia seeds, hemp seeds or ground flaxseed.
  • Don’t have frozen fruit, then fresh fruit works too, but adjust the liquid amount as needed since fresh fruit releases more water. Why not try my delicious Stewed Apple Overnight Oats
  • Experiment with different flavours by adding spices like cinnamon, nutmeg, or ginger for a flavour boost.
  • Make it a complete nutritious breakfast by adding a sprinkle of chopped nuts, granola, or even a drizzle of dark chocolate!
  • Swirls through some nut or seed butter to add a little healthy fat which can also help to stabilise blood sugars. My favourite is a good dollop of peanut butter!
  • Use your Fruit of Choice – Try tropical fruits like mango and pineapple with coconut milk for a tropical twist
  • Not sweet enough? – Add a little maple syrup or sweetener like my Simple Sugar Free Syrup
  • Top with extra fruit and sprinkle of nuts and seeds
