Saccharin has 132 kcal per 100 g and is roughly 300–400× sweeter than sugar. A typical packet contains 12 mg of sweetener — the per-100 g value is meaningless in practice. JECFA confirms safety at 5 mg/kg/day. Used in tabletop and reduced-calorie products since 1879.
How should I track Jams and preserves, no sugar (with sodium saccharin), any flavor?
The trickiest part about tracking Jams and preserves, no sugar (with sodium saccharin), any flavor is that small portions pack a lot of calories, and most people estimate sweet portions poorly. Research (Almiron-Roig et al., Appetite 2013) found that calorie-dense foods are underestimated by 50–200% when portioned by eye. Weighing on a scale takes the guesswork out. And here is the mindset shift that helps: tracking sweets is not about guilt. It is about awareness. When you log a treat honestly, you can plan around it and still hit your targets for the day.
