Natural sweeteners, like stevia and monk fruit, are extracted from plants and are often marketed as "clean label" options. Artificial sweeteners, such as aspartame and sucralose, are chemically synthesized. Both provide low or zero calories, but consumer preference often leans toward natural sources due to perceived safety and minimal processing.

Yes, sugar alcohols like erythritol and xylitol are considered sugar-free because they don’t raise blood sugar levels like regular sugar. They do contain some calories (though fewer than sugar) and are often used in "net carb" calculations for low-carb and keto products.

Some sweeteners, especially sugar alcohols (e.g., maltitol, sorbitol), may cause bloating, gas, or laxative effects if consumed in large amounts. High-intensity sweeteners like stevia or sucralose are generally better tolerated in small doses. It's best to moderate intake and check product labels if you have a sensitive stomach.
