Erythritol vs. Splenda — What's the Difference?

Difference Between Erythritol and Splenda


Key Differences

Origin & Composition: Erythritol is a sugar alcohol naturally found in certain fruits and fermented foods. It is often extracted from corn. On the other hand, Splenda is a branded product with its primary ingredient being sucralose, a chemically modified form of sugar.
Caloric Value & Sweetness: Erythritol contains almost zero calories and is about 70% as sweet as table sugar. Splenda, though calorie-free in small amounts, contains fillers like maltodextrin and dextrose which may contribute calories in larger quantities. Splenda is significantly sweeter than sugar, necessitating lesser amounts for a similar sweetness level.
Digestive Impact: Erythritol is known for being easily tolerated by the digestive system, with minimal side effects when consumed in reasonable amounts. Splenda, particularly because of sucralose, can have varying digestive effects on individuals, with some reports of bloating or gas.
Usage & Versatility: Erythritol is commonly used in baking and cooking because it doesn't degrade under heat. Splenda, while versatile and heat-stable, might not always replicate the texture and bulk of sugar in recipes.
Popularity & Accessibility: While Erythritol has gained popularity among health enthusiasts and the keto community, Splenda, due to its brand recognition, is widely available in grocery stores and often provided in packets at restaurants and cafes.
