LoGicane™: your questions answered

Alan Barclay

The launch of the low GI sweetener LoGicane™ in Australia in March sparked immense interest from around the globe. A growing disenchantment with non-nutritive tabletop sweeteners like aspartame and sucralose, and the hypothesis that high fructose corn syrups are fuelling the obesity epidemic in the USA, are a couple of likely reasons for the high level of interest.

How does LoGicane™ compare with other tabletop sweeteners?

It is important to realise that it is a nutritive sweetener – it provides energy (kilojoules) and carbohydrate, as well as small amounts of minerals like potassium, calcium and magnesium, and other nutritive substances like polyphenols and antioxidants. Other nutritive sweeteners like honey and raw sugar also provide similar amounts of energy, carbohydrate and some of these other nutrients, but on average, they have a higher GI value. All other nutritive tabletop sweeteners are so highly refined that they only provide energy and carbohydrate, and with the notable exception of fructose, have a higher GI. Therefore, LoGicane™ is an overall better choice of nutritive tabletop sweetener.

However, like all nutritive sweeteners, it may contribute to weight gain, and will elevate blood glucose levels in people with diabetes, if consumed in excessive amounts. It is worth noting that total sugar consumption per head of population has been decreasing in Australia over the last 35 years, while rates of overweight/obesity and type 2 diabetes have approximately trebled over the same period.


How does LoGicane™ compare with non-nutritive table top sweeteners like aspartame and sucralose?
As their name suggests, non-nutritive sweeteners provide essentially no nutrients (energy, carbohydrate, minerals, etc…) when consumed as directed. As such, they will not affect blood glucose levels, and in theory may aid in weight management. However, perhaps surprisingly, there is actually little evidence that they help with weight management for reasons that are as yet unclear. It is worth noting that aspartame and sucralose were introduced into the food supply in the early 1980’s and 90’s respectively, again coinciding with the global obesity and diabetes epidemic.

Is Logicane™ low GI due to added chemicals or sweeteners?
Logicane™ is low GI due to the polyphenols that occur naturally in molasses. The important GI lowering polyphenols in molasses are recovered using a membrane filtration process and this material is reincorporated back into washed raw sugar crystals to ensure the clinically “right” amount is captured in the final sugar product to ensure it is low GI.

Where can you buy it?
While LoGicane™ is currently only available in Australia and New Zealand supermarkets, Horizon Science are negotiating with major North American and European manufacturers, and expect the product will be available in these territories in the near future. For more information email:
