Sucralose can be up to 1, times sweeter than table sugar and so very small amounts are needed to achieve sweetness. Sucralose keeps its flavour and taste even when baked at high temperatures, hence it can be a popular choice for baking and recipes to replace sugar. This type of sweetener is commonly found in diet drinks such as stores own brand No Added Sugar fruit squashes, stores own brand fizzy diet drinks, stores own brand low sugar sauces eg.
Sucralose has been reported to cause bloating, cramping, flatulence and cause laxative effects in some individuals, usually when consumed in larger amounts. Stevia can be around times sweeter than table sugar. There are many different grades of stevia and also different methods of extraction.
IMPORTANT NOTE: Stevia is usually mixed with other bulking agents such as maltodextrin which has a higher GI value than table sugar and spikes blood glucose levels rapidly , or other sweeteners such as artificial sweeteners like sucralose, or sugar alcohols polyols such as erythritol.
Stevia products can leave a bitter aftertaste, especially cheaper stevia sweeteners which contain very small amounts of stevia. Absorption of NNSs [non-nutritive sweeteners] into the bloodstream occurs in the small intestine and can be transferred to a fetus through the placenta and to an infant through breast milk. Sugar Alcohols, also known as Polyols are small-chain carbohydrates that occur naturally in certain fruits, vegetables and plants. The name comes from their chemical structure which resembles sugar and is similar to alcohol.
Polyols are slowly digested. The glycaemic index is a rating system for foods containing carbohydrates. It shows how quickly each food affects your blood sugar glucose level when that food is eaten on its own. The GI of glucose is and table sugar sucrose is Only small amounts of polyols are absorbed in the small intestines, therefore polyols largely remain intact when entering the large intestines. Polyols attract water as they move through the small intestine by a process called osmosis.
This occurs whether polyols are absorbed, or not, but it can lead to pain and motility problems typically, diarrhoea for people who are more sensitive to the pressure this fluid exerts on the intestinal walls. Polyols that are not absorbed in the small intestine enter the large intestine where they are fermented by gut bacteria. The gas produced as a by-product of this bacterial fermentation distends the bowel, causing additional pain, bloating, and altered bowel habits in susceptible individuals.
This reduces both the osmotic effect they exert in the small intestine and the amount of intact polyol molecules available for fermentation in the large intestine.
Polyols are listed under carbohydrates on nutritional labels, however, not all carbs from polyols are digestible, therefore some polyols can be deducted from the total carb amount when looking at the carbs that impact blood sugar levels depending on the polyol type. Xylitol: The GI value of xylitol varies from one product to another. As this brand of xylitol does not cause spikes in blood sugar levels, I deduct the carbs found in xylitol in my recipes.
Maltitol: The GI value of maltitol is much higher at 35, therefore it is important to recognise that this sweetener will impact blood glucose levels more. In the knowledge that the GI of table sugar is 65, you could halve the carbs found in polyols from maltitol to give an estimate of the impact the carbs could have. As opposed to the negative impact non-nutritive sweeteners have on the gut microbiome, some polyols have been found to have positive effects, increasing the probiotic bacterias found in the gut after consumption.
Effects of polyols on gut microbiota composition. Erythritol, sorbitol, and mannitol do not affect the composition of the gut microbiota; however, lactitol, isomalt, xylitol, and maltitol provoke shifts in the gut microbiome, increasing bifidobacteria numbers in healthy people. So please be warned, if you want some sugar-free sweets do not risk more than two or three individual sweets at a time, or you could end up regretting the decision to have a treat!
Honey in particular is raised in my Facebook support group as something that many perceive as being a natural alternative to cane or beet table sugar, however, raw honey still spikes blood sugar levels.
Some may have a lower GI Glycaemic Index than table sugar, but they will still all raise blood sugar levels:. Agave nectar is very similar to honey or syrup as it is a runny texture which can be used for drizzling. Agave nectar or syrup is produced commercially in Mexico and South America from the agave plant the tequila plant. Agave is commonly marketed as a slow-release carbohydrate with a low glycaemic index. This is true as it contains mainly fructose and only low amounts of glucose.
This can cause major increases in long-term blood sugar and insulin levels, strongly raising the risk of metabolic syndrome and type 2 diabetes. The liver metabolises fructose, but when overloaded it starts turning the fructose into fat globules, which raise blood triglycerides. Having a high level of triglycerides in your blood can increase your risk of heart disease. Some sweeteners in pregnancy are safer than others, with some artificial sweeteners being linked to concerns for both the health of the mother and the child in later life.

The way novel sweeteners are made i. Sugar alcohols polyols : Technically not sugars, sugar alcohols are carbs that occur naturally in certain fruits and vegetables — although they can also be found in many processed foods. And despite their name, these sugars are non-alcoholic. Food labels may use the general term "sugar alcohol" or list the specific name, such as sorbitol.
When eaten in large amounts, sugar alcohols can have a laxative effect. When used in moderation, most pregnant women can safely use any of the eight nutritive and nonnutritive sweeteners approved by the U.
Still, the truth is that sugar substitutes can be a bit of a mixed bag for pregnant women.

Before you leap to consume all these tasty treats, remember everything in moderation. Stevia is a zero-calorie sweetener derived from a South American shrub. Although experts do say stevia does not pose some of the same dangers of sweet addiction that other artificial sweeteners do it does not raise your blood sugar or have any adverse effects on your taste buds your best bet is to check with your doctor before using it.
Even though the FDA does consider saccharin to be safe to use for the general public, saccharin may pose a risk of increased bladder tumors in children who are exposed to it in utero. In fact, saccharin has been banned in some countries as an artificial sweetener. The American Dietetic Association ADA says that saccharin can cross the placenta and stay in the baby's tissues, and the long-term effects, if any, are unknown. Although it is not used as much today as in the past, it still appears in many foods and beverages.
