If you’re managing diabetes, following a keto lifestyle, or optimising your metabolic health, you’ve likely spent plenty of time thinking about what impacts blood sugar and what does not. At the top of that list is monitoring one specific metric: blood sugar spikes.
In Australia, the health conversation is shifting. We are moving away from just counting calories to focusing on our glycemic response—how the food we eat impacts our blood glucose and insulin levels. We are learning what caused inflammation in our bodies.
When you crave something sweet, the choice usually boils down to regular sugar vs sweeteners. But why does regular sugar cause a roller coaster of energy crashes, while a natural alternative like a monk fruit keeps your levels completely steady?
The Anatomy of a Sugar Spike
To understand why monk fruit is so revolutionary, we first need to look at what happens when you consume regular table sugar (sucrose). Sucrose is a double sugar made of 50% glucose and 50% fructose. When digested, it quickly breaks down:
Over time, frequent insulin spikes can lead to insulin resistance—the root cause of Type 2 diabetes and metabolic dysfunction.
Monk Fruit & Erythritol: Sweetness Without the Spike
Monk fruit is a small, green melon native to Southeast Asia that delivers incredible sweetness with a zero glycemic response.
How? The sweetness of regular sugar comes from carbohydrates, which your body metabolises into glucose. The sweetness of monk fruit, however, comes from unique antioxidants called mogrosides. Your upper digestive tract cannot break down mogrosides for fuel, so they pass through without being absorbed into your bloodstream. No glucose enters your blood, meaning zero impact on your insulin levels.
Because pure monk fruit extract is up to 250 times sweeter than regular sugar it limits its usability in everyday life. Lakanto mindfully combines it with erythritol to create a perfect 1:1 sugar replacement; an easy swap for drinks, baking and cooking.
Erythritol is a naturally occurring sugar alcohol found in foods like pears and grapes. Unlike other sugar alcohols that can cause digestive distress, erythritol is uniquely absorbed in the small intestine and excreted unchanged in the urine. It provides zero calories, has a glycemic index of zero, and causes a significantly smaller—or non-existent—postprandial rise compared to regular sugar.
Natural Sweeteners vs Artificial Sweeteners
When looking for alternatives, source matters. Chemical-based artificial sweeteners (like aspartame or sucralose) are synthetic compounds. While they may not raise blood sugar in the short term, emerging research suggests they can negatively alter the gut microbiome.
By choosing a natural sweetener like our Lakanto Monkfruit Sweetener, you are opting for a plant-based, minimally processed alternative that works with your body’s natural biology.
The Takeaway
Managing your postprandial glucose doesn't mean giving up sweetness; it’s simply about changing the source. Swapping regular sugar for Lakanto Monkfruit Sweetener allows you to enjoy your favourite treats while keeping your blood sugar stable and supporting your long-term metabolic health.

Disclaimer: While monk fruit and erythritol are widely celebrated for having a minimal to zero impact on blood glucose, individual metabolic responses can vary. We always recommend checking your individual postprandial glucose levels to see how your body responds.
