The Fibre Fix: Your Secret Weapon for Blood Sugar Control
Let’s be real—navigating blood sugar ups and downs can feel like a rollercoaster. But here’s some good news you can chew on: fibre is your steadying force, your health wingman, your unshakable ally in the battle against blood sugar spikes.
If you’ve got prediabetes, Type 2 diabetes, or just want to stay ahead of the curve, fibre is not just “nice to have”—it’s non-negotiable.
Why Fibre? Because It’s Magic for Your Metabolism.
You’ve probably heard fibre is good for your gut. True. But that’s just the tip of the oat flake.
A fibre-rich diet has been tied to lower risks of heart disease, stroke, Type 2 diabetes, and even colorectal and breast cancer.
Oh, and it keeps things moving down there. (You know what we mean.)
But here’s the clutch detail: fibre also helps regulate blood sugar like a boss.
Let’s Break It Down: How Fibre Works for You
There are two types of fibre—soluble and insoluble. Both are heroes. But if we’re talking blood sugar control, soluble fibre, especially the thick, sticky kind called viscous fibre, deserves a standing ovation.
Here’s how it works:
-
It turns into a gel in your stomach (yep, like jelly).
-
That gel slows down how fast food leaves your stomach and enters your small intestine.
-
Translation: your body absorbs glucose more gradually, avoiding the dreaded post-meal sugar spikes.
-
Bonus: your gut bacteria ferment this fibre and produce short-chain fatty acids that boost insulin sensitivity and improve long-term blood sugar levels (a.k.a. your A1c score).
In fact, a 2019 Canadian review of 28 clinical trials showed that just 13 grams of soluble fibre per day lowered A1c in people with Type 2 diabetes. That’s powerful.
So, How Much Fibre Do You Need?
Let’s get to the numbers:
-
Women (19–50): Aim for 25 g/day
-
Men (19–50): Aim for 38 g/day
-
Over 50? Slightly less—but don’t drop below 21 g (women) or 30 g (men)
Pro tip: Shoot for 10 grams of fibre per meal to keep your blood sugar on an even keel.
