Frequently Asked Questions

What is the safest artificial sweetener?
Based on current regulatory consensus, stevia (steviol glycosides, E960) and thaumatin (E957) are considered among the safest sweeteners, with approvals in all major markets and no significant controversy. Isomalt (E953) and neotame (E961) also have strong safety profiles. However, 'safe' is relative to the amount consumed — all approved sweeteners are considered safe within their recommended daily intake.
Is aspartame safe?
Aspartame is approved in over 100 countries and has been extensively studied. However, it remains controversial. In 2023, the WHO's IARC classified it as 'possibly carcinogenic to humans' (Group 2B), while the JECFA maintained the existing acceptable daily intake. Most regulatory agencies consider it safe in normal consumption amounts, but people with PKU (phenylketonuria) must avoid it.
What is the difference between natural and artificial sweeteners?
Natural sweeteners come from plant sources (stevia, monk fruit, thaumatin). Artificial sweeteners are chemically synthesized (aspartame, sucralose, saccharin, acesulfame K). Sugar alcohols (erythritol, xylitol, sorbitol) are a middle category — derived from natural sources but processed. Natural doesn't automatically mean safer; the safety of any sweetener depends on the specific substance and consumption level.
Which sweeteners should I avoid?
Based on our data, sweeteners with 'avoid' safety ratings or high controversy levels deserve more caution. Cyclamate is banned in the US. Some sugar alcohols (sorbitol, mannitol) can cause digestive issues in large amounts. Ultimately, moderation is key with any sweetener. Check individual additive pages on AdditiveChecker for detailed safety information.
