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?
A diet with almost no vegetables and no legumes is healthy.
2. What is demonstrably correct?
Specific vegetables carry specific, avoidable risks (bitter zucchini, contaminated produce, extreme juicing, infant nitrate).
3. What is wrong or exaggerated?
Fruit and vegetables: RR 0.90 for all-cause mortality per 200 g/day (Aune 2017), with benefits up to 800 g/day; green leafy vegetables and salads were inversely associated with CVD and mortality. Fibre: 15-30% lower mortality and disease incidence at highest vs lowest intake; greatest benefit at 25-29 g/day (Reynolds 2019). Potassium (mainly from vegetables, legumes, fruit) lowers blood pressure in hypertension (indirect for vegetables: 20 of the 22 trials used potassium supplements) and is associated with 24% lower stroke risk (Aburto 2013). Legumes lower LDL (Ha 2014) and are associated with lower mortality (Zargarzadeh 2023). Vegetables and legumes are main sources of folate; folate needs are higher in pregnancy.
4. What remains unclear?
Observational associations may be partly confounded; the exact harm of complete elimination has not been tested.
5. Which studies support it?
None.
6. Which studies contradict it?
Aune 2017; Reynolds 2019; Aburto 2013; Ha 2014; Zargarzadeh 2023; Taylor 2009.
7. What applies to Germany and Europe?
German (DGE) and EU guidance recommend daily vegetables and regular pulses (not fetched in this review).
8. What is known about Egypt?
In Egypt, vegetables and legumes are central, affordable sources of fibre, potassium and folate.
9. What practical conclusion is appropriate?
Excluding vegetables and legumes for everyone is not consistent with the evidence; specific risks can be managed individually.
Assessment details
- Rationale for certainty of evidence
Consistent dose-response cohort meta-analyses link fruit/vegetable and fibre intake with lower mortality, CVD and cancer; RCTs show causal effects of fibre, potassium and pulses on risk factors (body weight, blood pressure, LDL). No trial has tested total vegetable elimination, so certainty is moderate.
- Source quality
Food lists (archive and third-party) and archive quote.
- Regional transferability
Applies to Germany and Egypt.
- Individual exceptions
Temporary restriction of specific vegetables may be appropriate in IBS, certain bowel obstructions, potassium restriction in advanced CKD, or individual allergy.
- Regional scope of the claim
- general (biological/medical)
- Last reviewed
- 25 October 2026 provisional
In plain language
The Tayyibat lists ban almost all vegetables, salads and legumes. Large studies consistently link eating more vegetables, fruit, fibre and legumes with lower rates of heart disease, stroke, some cancers and death. Trials show that fibre, potassium and pulses improve weight, blood pressure and cholesterol. Vegetables and legumes are also key sources of folate, which is especially important before and during pregnancy. The specific risks the archive mentions can be managed without giving up these foods.

General scientific assessment
Mostly false Avoiding nearly all vegetables and legumes contradicts a large and consistent body of evidence.
The following areas of food safety are relevant to this statement:
- Pesticides and pesticide residues
- Contaminants (heavy metals, PFAS, PCBs, dioxins, nitrate)
- Mycotoxins (mould toxins)
- Pathogens (Salmonella, Campylobacter, etc.)
