Spenda And Keto: Friends Or Foes?

The keto diet is a low-carb, high-fat eating plan that involves cutting back on high-carb foods like starches, desserts, and processed snacks. Sucralose, often known by its brand name Splenda, is a calorie-free, high-intensity sugar substitute that is 600 times sweeter than table sugar. While Splenda is technically keto-friendly, there are concerns about its impact on gut health, blood sugar levels, and insulin response. Some studies suggest that Splenda may alter the gut microbiome, leading to issues with digestion and immune function. It can also cause an increase in insulin levels, which is counter to the goal of keto, which is to keep insulin levels low and steady to promote fat-burning and weight loss.

Splenda's impact on gut health and microbiome

Splenda is the commercial brand name for sucralose, an artificial sweetener made from table sugar. It is about 600 times sweeter than table sugar and is easily the most popular artificial sweetener on the market.

While Splenda is a good alternative for those who are calorie-conscious, there are concerns about its impact on gut health and the microbiome. The artificial sweetener has been linked to an increased risk of inflammatory bowel disease (IBD) and has been shown to negatively impact the intestinal microbiota in mice.

One study found that Splenda increased the abundance of bacterial genes related to pro-inflammatory mediators, specifically genes related to lipopolysaccharide (LPS) synthesis, flagella protein synthesis, and fimbriae synthesis, as well as bacterial toxins and drug resistance genes. LPS, flagella, and fimbriae are known pathogen-associated molecular patterns (PAMPs) that can trigger pathological inflammation in the host, and bacterial toxins can induce toxicity.

Another study found that Splenda consumption was associated with altered gut bacteria and signs of chronic liver inflammation in rats. The sucralose-fed rats showed an overgrowth of E. Coli in the intestines and increased bacterial penetration into the gut wall.

In humans, the effect of sucralose on the gut microbiome has not been extensively studied, but some research suggests that non-nutritive sweeteners like Splenda can induce specific changes in glycemic response by modifying the gut microbiome. This challenges the notion that these sugar substitutes are biologically inert.

Overall, while Splenda may be a good option for those looking to reduce their calorie intake, its impact on gut health and the microbiome is a cause for concern and further research is needed to fully understand the potential risks.

Is Splenda a zero-calorie sweetener?

Splenda is a zero-calorie sweetener and sugar substitute. It is made in the USA and is the number one recommended sweetener brand by doctors and dietitians. It is also America's favourite sweetener brand.

Splenda comes in various forms, including sweetener packets, granulated sweetener, liquid sweetener, and sweetener blends. Each packet of Splenda provides the sweetness of two teaspoons of sugar without any calories. It can be used in place of sugar or agave nectar in coffee, tea, baking, and more.

Splenda also offers a range of products specifically for people with diabetes or those following a low-carb lifestyle, such as Splenda Diabetes Care Shakes and Splenda Water Enhancers.

The brand claims to be on a mission to help people reduce sugar from their diets and achieve their health goals.

Is Splenda a keto-friendly sweetener?

Splenda is a highly controversial sweetener. Some keto dieters love it, while others stay away. So, what is Splenda, and is it keto-friendly?

Splenda is the commercial brand name for sucralose, an artificial sweetener made from table sugar. Sucralose is about 600 times sweeter than sucrose (table sugar). To make sucralose, chlorine is added to sugar (sucrose) molecules using a chemical process. This way, the sugar cannot cross into the bloodstream and therefore should not cause a rise in blood sugar levels, at least in theory.

Technically, yes. One packet of Splenda has 1 gram of total carbs and three calories. But you only require a little because it’s so sweet, making it practically a zero-calorie and zero-carb sweetener. However, there are some concerns to account for.

Research shows that maltodextrin, one of the ingredients in Splenda, spikes blood sugar and insulin levels due to its high glycemic index score of 110. Another ingredient, dextrose, is just another word for glucose, which is absorbed into the bloodstream without needing any additional breakdown during digestion.

While sucralose cannot be metabolized by the body, and Splenda is advertised as a zero-calorie sweetener, this is not entirely accurate. The glucose and maltodextrin in Splenda contribute about 3.4 kcal per serving.

There are also concerns about the safety of Splenda, especially when used in cooking. Some studies have found that sucralose could produce harmful compounds when exposed to high temperatures. One study found that in the presence of glycerols (a component of fats), heating sucralose yields potentially cancerous chemicals known as chloropropanols.

Keto-Friendly Sweeteners

Instead of Splenda, you can try these keto-friendly sweeteners:

• Monk fruit sweetener
• Erythritol
• Allulose
• Stevia

These sweeteners are far healthier and tastier than Splenda, and they won't raise your blood sugar or insulin levels like Splenda can.

How does Splenda affect insulin levels?

Splenda is the commercial brand name for sucralose, an artificial sweetener made from table sugar. Sucralose is about 600 times sweeter than sucrose (table sugar). While sucralose cannot be metabolized by the body, Splenda is not entirely calorie-free because it contains dextrose and maltodextrin, which are carbohydrates.

The effect of Splenda on insulin levels is not entirely clear. Some studies have shown that sucralose ingestion leads to raised insulin levels. For example, a 2018 study showed that sucralose increases insulin production by triggering the release of the hormone glucagon-like-peptide 1 (GLP-1). Another study found that people who were given sucralose had 20% higher blood insulin levels than those given water.

However, other studies have found conflicting results, showing that sucralose does not affect GLP-1 production and therefore does not impact insulin levels. One such study injected sucralose directly into the stomach, bypassing the mouth, and found no significant rise in insulin levels.

The effect of Splenda on insulin levels may also be influenced by the presence of dextrose and maltodextrin, which can cause a small insulin response. Additionally, there is evidence that artificial sweeteners like Splenda can affect the body's insulin response over time, with one study finding that patients with Type II diabetes who consumed artificial sweeteners had higher levels of insulin resistance.

While the direct effect of Splenda on insulin levels is not conclusive, it is important to note that the sweet taste of artificial sweeteners can trigger cephalic phase insulin release, causing a small rise in insulin levels. This response is triggered by the sight, smell, taste, chewing, and swallowing of food.

In summary, while Splenda may not directly affect insulin levels in the same way as sugar, it is not entirely inert and may impact insulin levels through other mechanisms. More research is needed to fully understand the effects of Splenda and other artificial sweeteners on insulin levels, especially over the long term.

What are some healthier alternatives to Splenda?

While Splenda is a popular alternative to sugar, it is not the healthiest option. It is made from sugar molecules that are chemically altered to prevent them from being absorbed into the bloodstream. However, Splenda contains other ingredients that contribute to its calorie count and can cause a rise in blood sugar levels.

Stevia

Stevia is a natural sweetener derived from the Stevia rebaudiana plant. It is considered a nonnutritive sweetener, meaning it contains little to no calories or carbs. It is 200 to 300 times sweeter than table sugar and can be used to sweeten everything from drinks to desserts. It is also heat-stable, making it a good option for cooking and baking.

Monk Fruit

Monk fruit is a natural sweetener extracted from a plant native to southern China. It contains natural sugars and compounds called mogrosides, which are antioxidants and are 100–350 times sweeter than sucrose. Monk fruit extract is a no-calorie sugar alternative and is approximately 300 times sweeter than sucrose.

Erythritol

Erythritol is a type of sugar alcohol that occurs naturally in many vegetables and fruits. It is up to 80% as sweet as regular sugar but contains only 5% of the calories. Studies have shown that it may help lower blood sugar levels and is well-tolerated by the gut. It can be used in baking and cooking and substituted for sugar in various recipes.

Fresh Fruits

Fresh fruits like bananas, berries, and dates are naturally sweet and packed with important nutrients. The fiber in fruit helps slow down the absorption of sugar in the body, which helps regulate blood sugar levels. Fruits can be used as toppings, blended into smoothies, or added to baked goods.
