Aspartame (Equal)

About 200 times sweeter than sugar, aspartame is used in many diet sodas.

• It is a low-calorie sweetener but not suitable for baking as it loses sweetness at high temperatures.
• Individuals with phenylketonuria (PKU) must avoid aspartame.

Sugar Alcohols

Polyols, or sugar alcohols, are carbohydrates with a chemical structure similar to both sugar and alcohol.

Erythritol

Erythritol is found naturally in some fruits and has almost zero calories, making it well-tolerated for most.

• It has a GI of 1 and is less likely than other sugar alcohols to cause digestive issues.
• Best for: Baking and recipes where its near-zero-calorie property is desired.

Xylitol

Xylitol is a natural sugar alcohol derived from plants.

• It has a lower calorie count than sugar and a GI of 7.
• Large amounts can cause gastrointestinal discomfort.
