Scientific assessment
Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.
Certainty of evidence: moderate – Further research may still affect the assessment.
1. What was claimed?
Liver and offal are freely allowed.
2. What is demonstrably correct?
Liver is a dense source of iron, vitamin B12 and vitamin A; in WHO dietary modelling, best-case diets for young children included liver, red meat or small fish (I-EGG-103). Occasional consumption is acceptable for most non-pregnant adults.
3. What is wrong or exaggerated?
No limit or exception is given. EFSA advises that liver and offal be eaten at most about once a month to stay below the vitamin A upper limit, and not at all by women who are pregnant or planning pregnancy (I-MEAT-105). One 100 g portion of beef liver can contain 1.7-5.6 times the daily upper limit (I-MEAT-106). High preformed vitamin A intake (>15,000 IU/day) was associated with a 3.5-fold prevalence of cranial-neural-crest defects (I-MEAT-06). The UK NHS lists 'liver and liver products' among foods to avoid in pregnancy (I-MEAT-07). Men in the highest quintile of meat intake had a 41% higher gout risk (RR 1.41, I-MEAT-08), and the ACR conditionally recommends limiting purine intake in gout (I-MEAT-107). The rule also contradicts Elawady's own statement that liver is more harmful than meat (C-MEAT-02), and is inconsistent with limiting muscle meat to once a week.
4. What remains unclear?
Typical liver portion sizes among followers.
5. Which studies support it?
None that supports unrestricted intake. I-EGG-103 supports the nutritional value of liver in small amounts.
6. Which studies contradict it?
I-MEAT-105 (EFSA 2024: liver/offal at most once a month; none in pregnancy or when planning pregnancy), I-MEAT-106 (retinol content of liver), I-MEAT-06, I-MEAT-07, I-MEAT-08, I-MEAT-107 (ACR gout guideline).
7. What applies to Germany and Europe?
EFSA (2024) advises limiting liver and offal to once a month or less and no liver products for women who are pregnant or planning pregnancy (I-MEAT-105). Official pregnancy advice in the UK (I-MEAT-07) also advises avoiding liver.
8. What is known about Egypt?
Liver (kebda iskandarani) and offal are common, affordable foods; pregnant followers may eat them often if they follow the list.
9. What practical conclusion is appropriate?
Liver can be part of a varied diet for most adults, but infrequently (EFSA: about once a month or less). Women who are pregnant or planning pregnancy should not eat liver or liver products, and people with gout should limit offal.
Assessment details
- Rationale for certainty of evidence
EFSA's 2024 opinion (I-MEAT-105) retains a tolerable upper intake of 3000 ug RE/day of preformed vitamin A, with teratogenicity as the critical effect, and states that Europeans are unlikely to exceed it only if liver and offal are eaten once a month or less; women planning pregnancy or pregnant are advised not to consume liver products. Measured bovine liver contains 5,213-16,948 ug retinol per 100 g, i.e. 1.7-5.6 times the upper limit per portion (I-MEAT-106). High vitamin A intake in early pregnancy is associated with birth defects (I-MEAT-06), and the NHS lists liver among foods to avoid in pregnancy (I-MEAT-07). People with gout are advised to limit purine-rich foods (I-MEAT-107). Not “False” because liver itself is a nutritious, permitted food in moderation.
- Source quality
Archive food list and third-party site; contradicted by Elawady's own statements on liver.
- Regional transferability
Universal physiology; offal is popular and affordable in Egypt.
- Individual exceptions
Pregnant women or women planning pregnancy (vitamin A); people with gout or hyperuricaemia (purines); people taking vitamin A supplements.

What does the overall evidence say?
Editorial assessment based on the studies above – not itself a study result.
Which position is better supported?
Liver and offal are nutritious in moderation, but an unrestricted allowance is not safe: one portion of liver can exceed the vitamin A upper limit several-fold; EFSA advises liver at most about once a month and none in pregnancy or when planning pregnancy; people with gout are advised to limit purine-rich foods.
Why some studies weigh more
Official risk assessment (EFSA 2024) and health-service advice (NHS) are direct; measurement data quantify the dose.
Is a causal relationship established? Yes, established Teratogenicity of high preformed vitamin A is established (EFSA critical effect).
Remaining uncertainty
Vitamin A content of Egyptian liver; actual intake frequency among followers.
Justified conclusion
The rule should carry a frequency limit and a pregnancy exclusion.
Why do studies seem to disagree?
Nutritional value (WHO) vs vitamin A toxicity (EFSA): compatible; small, infrequent portions give benefits without exceeding the UL.
Does this depend on the country?
- General biological effects
- Vitamin A teratogenicity is universal.
- Eating habits
- Liver (e.g., kebda iskandarani) and offal are common and affordable in Egypt.
- Origin of the food
- Retinol content varies with breed and feed.
- Contaminants
- Liver also accumulates some metals and residues (C-MEAT-02).
- National production conditions
- No Egyptian liver retinol data reviewed.
- Legal rules
- Not applicable.
- Actual monitoring data
- Not applicable.
A regional difference that changes the conclusion is not supported by robust data.
Statistical re-check
- Retinol per portion vs EFSA UL and Rothman threshold – 50 g: 0.9-2.8 x UL; 100 g: 1.7-5.6 x UL (8,689-56,493 IU per 50-100 g); Rothman threshold 10,000 IU = 3000 ug = UL. recalculated
Certainty of the overall evidence (GRADE, simplified)
- Main outcome
- Exceeding the vitamin A UL / teratogenic risk with unrestricted liver intake
- Starting level
- high (randomised trials)
- Reasons for downgrading
- indirectness (no direct study of followers)
- Result
- moderate

History of the verdict
- 25 October 2026 · Phase 1 · Initial assessment: Potentially false (moderate)
- 26 October 2026 · Phase 4 (systematic evidence review) · Verdict changed: Potentially false (moderate) → Mostly false (moderate)
The EFSA 2024 opinion gives explicit, authoritative advice (liver/offal at most once a month; no liver products in pregnancy or when planning pregnancy) and liver retinol measurements show that one portion can exceed the upper limit several-fold. An unrestricted allowance is therefore contradicted by moderate-to-high-quality evidence, not merely doubtful. “Mostly false” rather than “False” because liver itself is a permitted, nutritious food.
New sources: I-MEAT-105 I-MEAT-106 I-MEAT-107 I-EGG-103
In plain language
The system allows liver and other organ meats without any limit, while it limits beef to once a week. Liver is very rich in vitamin A: one portion can contain several times the daily safe upper limit. Too much vitamin A early in pregnancy can harm the unborn baby, which is why the European Food Safety Authority advises eating liver at most about once a month and not at all during pregnancy or when planning one. Organ meats also raise uric acid and can trigger gout attacks. Dr. Elawady himself said in a video that liver is more harmful than meat.

Regional context
Germany / EU
EFSA (2024) advises limiting liver and offal to once a month or less and no liver products for women who are pregnant or planning pregnancy (I-MEAT-105). Official pregnancy advice in the UK (I-MEAT-07) also advises avoiding liver.
Egypt
Liver (kebda iskandarani) and offal are common, affordable foods; pregnant followers may eat them often if they follow the list.
What applies in my country?
General scientific assessment
Mostly false Liver and offal are nutritious in small amounts, but an unlimited allowance is not safe: EFSA advises about once a month at most and none in pregnancy.
The following areas of food safety are relevant to this statement:
- Veterinary medicines and antibiotics
- Hormonal growth promoters
- Contaminants (heavy metals, PFAS, PCBs, dioxins, nitrate)
- Pathogens (Salmonella, Campylobacter, etc.)
