Does consuming allulose (as a sugar substitute) affect insulin levels in blood? Does it really have a negligible effect or does the effect vary from person to person?
I have been using it in tea and for baking etc but am concerned that despite the claims it may be having a negative impact and giving me insulin spikes
Hello
Thank you for your query.
Allulose (also known as D-psicose) is a rare sugar that tastes similar to table sugar but provides very little energy and is absorbed and largely excreted rather than being significantly metabolised.
The current evidence suggests that allulose has little to no impact on blood glucose and insulin levels in most people. In some studies, it has even been shown to modestly reduce the rise in blood glucose after a meal containing carbohydrate. Therefore, for the majority of people, allulose appears to be a useful sugar substitute when trying to reduce sugar intake.
That said, as with many aspects of nutrition, there can be some individual variation. Factors such as overall insulin sensitivity, the amount consumed, and what it is eaten with may influence the response. However, any insulin effect is generally considered to be minimal and far smaller than that seen with sugar or refined carbohydrates.
From a practical perspective:
– Using allulose in tea or coffee is unlikely to have any meaningful impact on insulin levels.
– Using it in baking can be helpful, but it is worth remembering that the other ingredients in the recipe (e.g. flour or starches) may have a much greater effect on blood glucose and insulin than the sweetener itself.
– Some people may experience digestive symptoms such as bloating if large amounts are consumed.
Overall, if you are using allulose to replace sugar, it is very unlikely to be having a negative effect on your insulin levels and is generally considered a reasonable option.
The key message is that the major drivers of insulin secretion are digestible carbohydrates, particularly sugars and refined starches, rather than low-calorie sweeteners such as allulose.
