Scientific assessment
False – The statement contradicts the robust evidence.
Certainty of evidence: high – Further research is very unlikely to change the assessment.
1. What was claimed?
High sugar is protective; diabetes does not exist; HbA1c is a lie; unlimited sugar is fine.
2. What is demonstrably correct?
Acute stress (illness, surgery, exercise) raises glucose through cortisol, adrenaline and glucagon; transient stress hyperglycaemia is a real phenomenon and some critical-care researchers consider it adaptive (I-DIAB-107); tight glucose control in critically ill patients increased mortality (A-INS-02). HbA1c can be misleading in anaemia, haemoglobin disorders or G6PD deficiency (I-DIAB-108). Overly aggressive glucose lowering can harm (C-INS-04).
3. What is wrong or exaggerated?
Each 1% reduction in HbA1c was associated with 21% fewer diabetes-related deaths, 14% fewer myocardial infarctions and 37% fewer microvascular complications, with no threshold (I-INS-04). Intensive therapy reduced retinopathy by 76% in type 1 diabetes (I-INS-03) and microvascular endpoints by 25% in type 2 (A-INS-16). HbA1c is a validated measure of average glucose. 'Drink sugar' and 'no upper limit' contradict evidence on sugar-sweetened beverages and diabetes risk (topic of another rule).
4. What remains unclear?
It is unclear how literally followers understand slogans such as 'there is no such thing as diabetes'; no outcome data among followers were found. The adaptive role of short-term stress hyperglycaemia in acute illness is still studied, but this does not apply to chronic hyperglycaemia.
5. Which studies support it?
None for the general claim.
6. Which studies contradict it?
I-INS-03, I-INS-04, A-INS-16, I-INS-02, I-INS-103 (mortality rises with HbA1c in T1D), I-INS-104, I-DIAB-106 (HbA1c tracks average glucose, R2 0.84), I-SUG-03 and A-SOD-01 (sugars and sugar-sweetened beverages).
7. What applies to Germany and Europe?
European (EASD) and German (DDG) guidance follow the same evidence base as the ADA/EASD consensus: individualised HbA1c targets, insulin as mandatory therapy in type 1 diabetes, and SGLT2 inhibitors/GLP-1 receptor agonists for people with cardiovascular or kidney disease. No country-specific difference changes the assessment.
8. What is known about Egypt?
Egypt has one of the highest diabetes prevalences in the region; the same drug classes and insulins are used. Access barriers and cost may make advice to stop medication attractive, which increases the practical risk of this claim. No Egypt-specific evidence changes the assessment.
9. What practical conclusion is appropriate?
Chronically high blood glucose damages eyes, kidneys, nerves and vessels. Avoiding very low targets is reasonable; ignoring high glucose is not.
Assessment details
- Rationale for certainty of evidence
Prospective data (UKPDS 35) show a continuous relationship between HbA1c and complications without threshold; RCTs (DCCT, UKPDS) show that lowering glucose reduces retinopathy, nephropathy and neuropathy. Stress hyperglycaemia exists (kernel), but chronic hyperglycaemia causes organ damage.

Scientific evidence in detail
Scientifically refuted – High-quality evidence shows the opposite, or the claim contradicts well-established physiology.
Research question: In people with diabetes, is chronically raised blood glucose (HbA1c) harmless or protective, is HbA1c an invalid measure, and is there no upper limit for sugar intake?
Research question in detail (PECO)
- Population
- People with type 1 or type 2 diabetes; general population for sugar intake
- Intervention or exposure
- Chronic hyperglycaemia (higher HbA1c); high sugar intake
- Comparison
- Lower HbA1c; lower sugar intake
- Geographic scope
- universal biology
- Outcomes
- Microvascular and macrovascular complications
- Mortality
- Validity of HbA1c as average glucose
- Type 2 diabetes incidence (sugar-sweetened beverages)

What does the overall evidence say?
Editorial assessment based on the studies above – not itself a study result.
Which position is better supported?
Chronic hyperglycaemia causes organ damage and death; HbA1c is a validated measure of average glucose; sugar intake has upper limits recommended by WHO/EFSA.
Why some studies weigh more
RCTs (DCCT, UKPDS) and large cohorts with dose-response outweigh an opinion paper on acute stress hyperglycaemia and a review of HbA1c pitfalls.
Is a causal relationship established? Yes, established Randomised lowering of glucose reduces complications (DCCT, UKPDS) with dose-response in cohorts.
Remaining uncertainty
Optimal glucose in acute critical illness; HbA1c accuracy in anaemia/haemoglobinopathies.
Justified conclusion
The claim is false; only the acute-stress kernel and HbA1c caveats are correct.
Why do studies seem to disagree?
Apparent conflict between 'stress hyperglycaemia is adaptive' (I-DIAB-107, A-INS-02) and 'hyperglycaemia is harmful' (I-INS-03/04) reflects different questions: hours to days of acute illness versus months to years of diabetes. HbA1c limitations (I-DIAB-108) concern specific blood disorders, not the general validity shown by ADAG (I-DIAB-106).
Does this depend on the country?
- General biological effects
- Insulin physiology, autoimmune type 1 diabetes and ketoacidosis are universal human biology.
- Eating habits
- High intake of sugar-sweetened beverages occurs in Egypt and Europe; WHO/EFSA limits apply to both.
- Origin of the food
- Not relevant.
- Contaminants
- Not relevant.
- National production conditions
- Not relevant.
- Legal rules
- Insulin is an essential medicine (WHO list) in Egypt and the EU; prescription rules not relevant to the scientific question.
- Actual monitoring data
- HbA1c can be distorted by anaemia and haemoglobin disorders, which are common in Egypt; this calls for added glucose testing, not abandonment of measurement.
A regional difference that changes the conclusion is not supported by robust data.
Statistical re-check
- Convert HbA1c to estimated average glucose with the published regression – HbA1c 7% = 154 mg/dL, 9% = 212 mg/dL, 12% = 298 mg/dL; R2 0.84 indicates strong but imperfect individual agreement recalculated
- Crude mortality and CI symmetry – Crude death 8.0% vs 2.9% (crude ratio 2.79); CIs log-symmetric recalculated
Certainty of the overall evidence (GRADE, simplified)
- Main outcome
- Microvascular complications and mortality with chronic hyperglycaemia
- Starting level
- high (randomised trials)
- Reasons for upgrading
- dose-response (UKPDS 35, Lind 2014)
- Result

In plain language
Blood sugar can rise briefly during stress, and that is normal. But sugar that stays high for months and years damages the eyes, kidneys, nerves and blood vessels. Large studies show that the higher the long-term sugar (HbA1c), the more complications occur, and that lowering it prevents blindness and kidney failure.

Study explained simply
- What did the researchers want to find out?
Can a UL or safe level for dietary sugars be set?
- How was the study done?
Regulatory scientific opinion with systematic reviews.
- How many people, animals or samples were studied?
Not applicable; General population
- What was actually found?
Sugars are a well-established hazard for caries; RCTs on surrogate endpoints show causal positive relationship of added/free sugars with obesity and dyslipidaemia (moderate certainty), NAFLD and T2D (low), hypertension (very low); no safe level identified; intake of added and free sugars should be as low as possible in a nutritionally adequate diet.
- How large was the observed effect?
Not applicable
- What do the results mean in everyday life?
Applies to sugar, honey and syrups alike.
- What are the study's limitations?
Trials looked at markers (weight, liver fat, blood fats) rather than diseases; cohort studies mostly compared sugar with other calories at equal total energy; few data below 10% of energy.
- What does it say about Elawady's specific claim?
Contradicts C-SUG-01, C-SUG-05 (health relevance); supports C-SOD-01.

Directly applicable in EU/Germany.
- What can explicitly not be concluded from this study?
It cannot name a safe daily amount of sugar; it does not show that sugar is harmful when it does not add extra calories, except for tooth decay.

Is high blood sugar during severe illness protective?
Marik PE, Bellomo R. Crit Care 2013 · PMID 23470218 · DOI 10.1186/cc12514Narrative reviewindependent cross-checkabstract checked★ key studyCritical-care experts argue that a short-term rise in sugar during severe illness may be a survival response; this does not apply to long-term diabetes.
Acute stress hyperglycaemia may be adaptive; does not apply to chronic diabetes.
Does the study support the specific claim? Partly · Methodological quality: low · Certainty of evidence: see overall assessment of the claim

No study in this group is marked as key.
Regional context
Germany / EU
European (EASD) and German (DDG) guidance follow the same evidence base as the ADA/EASD consensus: individualised HbA1c targets, insulin as mandatory therapy in type 1 diabetes, and SGLT2 inhibitors/GLP-1 receptor agonists for people with cardiovascular or kidney disease. No country-specific difference changes the assessment.
Egypt
Egypt has one of the highest diabetes prevalences in the region; the same drug classes and insulins are used. Access barriers and cost may make advice to stop medication attractive, which increases the practical risk of this claim. No Egypt-specific evidence changes the assessment.
What applies in my country?
General scientific assessment
False Chronic high blood sugar is harmful; denying diabetes is false and dangerous.
This statement concerns biological or medical relationships. The scientific assessment above applies regardless of the country; country-specific food data do not change it.
