In brief: Sucralose is a low-calorie high-intensity sweetener, around 600 times sweeter than sugar.
Current safety assessment
| Item | Interpretation |
|---|---|
| Additive number | E955 |
| ADI | 15 mg/kg body weight/day |
| Current EU uses | Still assessed as safe in 2026 |
| Additional new uses | Not confirmed across the board |
In 2026, EFSA confirmed the existing ADI and the safety of currently authorised uses.[1]
Prolonged high-temperature heating needs separate assessment
EFSA could not confirm the safety of additional bakery uses because of uncertainties about prolonged heating at high temperatures. Chlorinated compounds whose health significance is unclear may also form during such heating at home. The assessment of existing uses therefore does not automatically apply to every heating process. The ADI is not a recommended target intake.
Gut and blood glucose
Studies on the microbiome and glucose metabolism do not give a consistent picture. Individual findings justify neither a health craze nor alarmism about dangers.
FAQ
Is sucralose carcinogenic?
EFSA currently identifies no such risk for authorised uses.
Does sucralose contain calories?
Very few in practice at usual amounts.
Does it affect blood glucose?
The effects are not consistent.
Is an unlimited amount safe?
No.
Conclusion
Sucralose can replace sugar, but like any additive it should be considered in the context of the overall diet.
