Explanation – Sucralose is a chemically modified form of sucrose, where three hydroxyl groups are replaced with chlorine atoms. This alteration makes sucralose much sweeter than sucrose (table sugar)—approximately 600 times sweeter—while also rendering it resistant to metabolism by the human body. When sucralose is consumed, it passes through the digestive system largely unchanged. The body does not break it down for energy, so it is not absorbed into the bloodstream to any significant extent. Instead, it is excreted unchanged in the urine. This lack of metabolism means that sucralose does not provide calories or contribute to blood glucose levels, making it an effective non-caloric sweetener for people looking to reduce their caloric intake or manage their blood sugar levels.
