- The archive homepage states that the forbidden-food section is supported by research 'independently of Dr. Diaa's words'. No evidence was found that Elawady himself cited these studies.
- Claimed mechanism
Sweetener toxicity, microbiome effects.

Scientific assessment
Unclear / insufficient evidence – The data do not allow an assessment either way.
Certainty of evidence: low – Further research is likely to change the assessment considerably.
1. What was claimed?
Sweeteners raise cancer and heart disease risk.
2. What is demonstrably correct?
Debras 2022 (A-UPF-18): higher sweetener consumers had cancer HR 1.13 (1.03-1.25); Debras 2022 (A-UPF-19): total sweeteners and CVD HR 1.09 (1.01-1.18), cerebrovascular 1.18.
3. What is wrong or exaggerated?
Single-cohort evidence; absolute incidence differences are small (e.g., CVD 346 vs 314 per 100,000 person-years); not established as causal.
4. What remains unclear?
Causality.
5. Which studies support it?
6. Which studies contradict it?
I-SOD-09 (JECFA ADI reaffirmed).
7. What applies to Germany and Europe?
EU-authorised sweeteners have ADIs; EFSA re-evaluation status not checked in this review.
8. What is known about Egypt?
No Egypt data.
9. What practical conclusion is appropriate?
No firm conclusion; avoiding sweeteners is optional, not medically required.
Assessment details
- Rationale for certainty of evidence
Associations from one large French cohort (HRs 1.09-1.40 with modest absolute differences); reverse causation and residual confounding possible; IARC found only 'limited' evidence for aspartame and liver cancer; JECFA kept the ADI.
- Source quality
Archive lists the NutriNet-Santé studies without interpretation; summary implies causal mechanisms.
- Regional transferability
High (French cohort; EU-authorised sweeteners).
- Individual exceptions
Not applicable.
- Regional scope of the claim
- general (biological/medical)
- Last reviewed
- 25 October 2026 provisional
In plain language
A large French study found slightly more cancer and heart disease among people who consumed more artificial sweeteners. This single study cannot prove that sweeteners are the cause. International experts concluded that aspartame is safe within the accepted daily limit, while asking for more research.

IARC and JECFA on aspartame

Study explained simply
- What did the researchers want to find out?
Carcinogenic hazard and acceptable intake of aspartame.
- How was the study done?
Joint hazard (IARC) and risk (JECFA) assessment (news release read in full).
- How many people, animals or samples were studied?
Not applicable; General population
- What was actually found?
IARC: Group 2B (limited evidence in humans for hepatocellular carcinoma; limited in animals; limited mechanistic). JECFA: no sufficient reason to change the ADI of 0-40 mg/kg bw; a 70 kg adult would need >9-14 cans/day (200-300 mg each) to exceed it. IARC classifications reflect strength of evidence, not risk at a given exposure.
- How large was the observed effect?
ADI 0-40 mg/kg bw
- What do the results mean in everyday life?
Normal intake is within the safe limit for most people.
- What are the study's limitations?
Limited evidence base
- What does it say about Elawady's specific claim?
- Do the results apply to Germany and Europe?
Applies; aspartame (E951) authorised in EU.
- What can explicitly not be concluded from this study?
That aspartame causes cancer.
No study in this group is marked as key.
