FACT OR FICTION?
Sucralose and the Ketogenic Diet
Sucralose, is a noncaloric artificial sweetener or sugar substitute that is in just about every low sugar, sugar free, 0 calorie food or beverage on the marketplace. Sucralose is safe for diabetics as it contains zero sugar and zero calories. Some branded sucralose products (namely Splenda) do contain maltodextrin or dextrose, increasing its caloric value to a whopping 3 calories per teaspoon. Since its discovery and introduction into the food supply sucralose has revolutionized the way people eat, however it has also been a controversial ingredient due to misinformation that exists in the marketplace. Recently, some Ketogenic Dieters have reignited the Sucralose debate claiming that true Keto should not include Sucralose. This article serves as a platform to discuss (and ultimately dispel) common myths about sucralose, specifically related to the Ketogenic Diet..
Sucralose is a carbohydrate that contains maltodextrin and/or dextrose which are carbohydrates, therefore it should not be used while on the Ketogenic Diet.
The most famous branded Sucralose product on the market is called Spleda. Splenda contains Sucralose. Splenda also contains Maltodextrin and/or dextrose as fillers. Maltodextrin and dextrose are carbohydrates that contain calories. Pure Sucralose, the kind used in thousands of beverages and foods around the globe is not a carbohydrate, and does not contain either maltodextrin and/or dextrose (it is pure), therefore it does not contain calories. Because Pure Sucralose is noncaloric it has a glycemic index of 0, its ingestion does not elevate blood sugar levels (glucose), therefore not impacting insulin levels. Ketogenic Dieters SHOULD use Pure Sucralose. Ketogenic Dieters should NOT use Splenda.
Sucralose is made from sugar.
Pure Sucralose IS made from sugar, created by chemically altering the sugar molecule. Sucralose is in fact 300-1000 times sweeter than sugar.
Natural sweeteners are better than sucralose for ketogenic dieters.
Not all natural sweeteners are created equal. While natural sweeteners like stevia and monk fruit don’t impact your blood glucose levels, other natural sweeteners like honey and sugar cane do. So even though a sweetener is natural doesn’t mean that it won’t impact your blood glucose levels. A general rule is to try and avoid high levels of sugar and honey while on a ketogenic diet.
Sucralose increases blood glucose levels.
There is some controversy surrounding whether or not sucralose impacts blood glucose levels due to a particular study on mice. In this particular study the mice showed increased blood sugar levels, in relation to sucralose, when the bacteria in the gut was changed or altered. There has only been one study, out of many, in human trials to find similar results. Thus, while this theory could be possible, there is not enough evidence to support it.
There have been plenty of human studies that illustrate sucralose having no impact at all on blood glucose levels. For example, in a randomized double-blind study that examined 47 men for a period of 12 weeks who had normal blood glucose levels and were either given a placebo or 1 gram of sucralose per day showed that there was no discernible difference between the sucralose group and the placebo group in any of the 4 tested parameters (HbA1c, C-peptide, fasting glucose, and insulin levels).
Due to the chemical makeup of Pure Sucralose, FINAFLEX food scientists conclude that because Pure Sucralose is noncaloric it does not impact blood glucose levels, therefore more than OK for ketogenic dieters to use. The results of countless human studies have supported this conclusion. FINAFLEX uses Pure Sucralose in its Ketogenic Line of Products. Give them a try today and Redefine Yourself!
